  • Colonizing Mars could be dangerous and ridiculously expensive. Elon Musk wants to do it anyway | CNN Business

    Colonizing Mars could be dangerous and ridiculously expensive. Elon Musk wants to do it anyway | CNN Business

    [ad_1]


    Austin, TX
    CNN Business
     — 

    Elon Musk has spent nearly two decades rallying SpaceX fans around his goal of colonizing Mars, something world governments aren’t currently attempting — in part because of the unfathomable price tag such a mission will entail.

    Musk, the company’s CEO and chief engineer, refers to his interplanetary ambitions more like a sci-fi protagonist with a moral calling than an entrepreneur with a disruptive business plan.

    “If there’s something terrible that happens on Earth, either made by humans or natural, we want to have, like, life insurance for life as a whole,” Musk said during a virtual Mars conference on Aug. 31. “Then, there’s the kind of excitement and adventure.”

    SpaceX’s plans for a Red-Planet settlement bring up numerous technological, political and ethical questions. One of the most challenging hurdles may also be financial: Not even Musk has ventured to guess an all-in cost estimate.

    The last space program that came close to Musk’s interplanetary travel ambitions was NASA’s Apollo program, the mid-20th Century effort that landed six spacecraft and 12 astronauts on the moon. Apollo cost well over $280 billion in today’s dollars, and, in some years, NASA was taking up more than 4% of the entire national budget. The space agency, which in more recent years has received less than half of one percent of the federal budget, is mapping its own plans to return humans to the moon and, eventually, a path to Mars.

    But the agency has not indicated how much the latter could cost, either.

    Musk’s personal wealth has ballooned to about $100 billion — at least on paper — thanks in no small part to a series of stock and stock awards from his electric car company, Tesla. Musk has also repeatedly said that he hopes profits from SpaceX’s other businesses, including a satellite-internet venture that is currently in beta testing, will help fuel development of his Mars rocket. SpaceX has also raised nearly $6 billion from banks and venture capitalists, swelling into one of the most highly-valued private companies in the world, according to data firm Pitchbook. Presumably, at least some investors will one day be looking to cash out.

    And that begs the question: Is there money to be made on Mars?

    SpaceX is likely still many, many years from developing all the technology a Mars settlement would require. The company is in the early stages of developing its Starship, a massive rocket and spaceship system that Musk hopes will ferry cargo and convoys of people across the at-minimum 30 million-mile void between Earth and Mars. Musk has estimated Starship development will cost up to $10 billion, and Musk said Aug. 31 that SpaceX will look to launch “hundreds” of satellites aboard Starship before entrusting it with human lives.

    If it proves capable of the trek to Mars, settlers will need air-tight habitats to shield them from toxic air and the deadly radiation that rains down on its surface.

    “It’s not for the faint of heart,” Musk said. “Good chance you’ll die, and it’s going to be tough going…It’d better be pretty glorious if it works out.”

    But for at least the first 100 years that humans have a presence on Mars, the economic situation will be dubious, said Michael Meyer, the lead scientist for NASA’s Mars Exploration Program, which recently launched the Perseverance rover to further study the planet robotically.

    Musk does have a plan for making Mars an attractive destination for long-term living: Terraforming, a hypothetical scenario in which humans make Mars more Earth-like by pumping gases into the atmosphere. It’d be an attempt to use the same greenhouse gases causing the climate crisis on our home planet to make Mars’ atmosphere thicker, warmer and more hospitable to life. Musk has promoted the idea that the process could be kicked off by dropping nuclear bombs on the planet.

    The idea of terraforming arose from scientists who were kicking around ideas, Meyer said, but not from anyone who thought it was something humans could or should do.

    “It was an intellectual exercise,” Meyer said. But there’s barely any oxygen in Mars’ atmosphere. And there’s an infinitesimally small amount of water, meaning it will be extremely difficult to grow crops, much less create a Mars-wide water cycle. It’s not even clear if there are enough resources on Mars to make terraforming possible at all.

    Musk, in a photo posted to his Instagram, wears one of SpaceX's

    “I think ‘Total Recall’ has the right idea,” he joked. “You’d need to use some alien technology.”

    Musk has also acknowledged that terraforming will be extremely resource-intensive. But the concept is ingrained in SpaceX lore, so much so that the company sells t-shirts saying “Nuke Mars” and “Occupy Mars.”

    Musk is frequently seen wearing one.

    Values and valuations

    There are no known resources on Mars that would be valuable enough to mine and sell back to Earthly businesses, Meyer said. “Part of the reason [scientists are] interested in Mars is — it’s pretty much made of the same stuff as Earth,” he told CNN Business.

    Musk has previously suggested that he agrees, noting that the resources on Mars would likely be valuable only to settlers hoping to build up industries on the planet. He noted eight years ago that the only “economic exchange” between Mars and Earth dwellers would be “intellectual property.”

    Mars, the fourth planet from the sun, has days that are roughly as long as Earth days. But it's a smaller planet, its temperatures average -81 degrees Fahrenheit, and its atmosphere is much thinner and comprised mostly of carbon dioxide.

    Money-making ambitions aside, the idea that Mars could one day become home to a metropolis and — potentially — a tourist destination is acknowledged by mainstream scientists like Meyer, NASA’s lead Mars expert.

    Meyer said that, 20 years ago, he attended a presentation about Mars business and tourism. “I went in pretty skeptical of this… and coming away I was thinking, ‘Well, [there are] some pretty reasonable ideas,” he said, adding that he now embraces the idea that businesspeople could make space travel more accessible.

    Meyer added that, in his mind, it’s not if Mars travel will one day be a profitable venture, but when.

    Musk hasn’t expanded on his ideas for making money on Mars, but his musings about exporting intellectual property echoed a book written by Robert Zubrin, an influential but polarizing figure in the space community and a longtime Musk ally.

    “Ideas may be another possible export for Martian colonists,” Zubrin, who heads the Mars Society, wrote in his oft-cited 1996 book, “The Case for Mars.”

    To look towards a potential future of humanity, Zubrin looks to its past.

    “Just as the labor shortage prevalent in colonial and 19th century America drove the creation of Yankee Ingenuity’s flood of inventions, so the conditions of extreme labor shortage…will tend to drive Martian ingenuity.”

    In a recent interview with CNN Business, Zubrin stood by those ideas, arguing American colonization has worked. Zubrin again harkens back to the colonization of North America as an example of how would-be Mars colonists might fund their trip.

    “If you say, okay, you want to go to Mars, you’re going to want to offer something,” Zubrin said. “If you look at Colonial America, a middle-class person could travel to America by liquidating their farm. But, the proceeds would give them a one-way ticket. But if you are working, what you could do is sell your labor for seven years. Remember the indentured servants?”

    “So there’ll be some selection for, like, you know, if you can pay it, you can go on your own terms — but if you can’t…effectively it’s like $300,000 which is about what a working person can make in seven years, or what a middle class person can put together by selling their house,” Zubrin added.

    Zubrin, who has worked with conservative think tanks but says he is not politically affiliated, also acknowledged that colonization can go hand-in-hand with exploitation: “If somebody says, ‘But won’t there be exploitation there?’ Well sure, that’s what people do to each other all the time.”

    (Musk has not expounded on his thoughts about colonialism, and he donates to both US political parties.)

    To be clear: The story of American colonialism also included chattel slavery and the brutalization and erasure of many native populations.

    “There aren’t native Martians,” Zubrin said.

    But Damien Williams — a teacher and PhD student at Virginia Tech who studies the intersection of advanced technologies, ethics and societies — warns that the stories we may tell ourselves about America and exploring outer space can leave out key context.

     A prototype of SpaceX's Starship spacecraft is seen at the company's Texas launch facility on September 28, 2019 in Boca Chica near Brownsville, Texas

    It’s still unclear, for example, who Musk envisions as the first Mars settlers. NASA astronauts? Ultra-wealthy thrill-seekers? SpaceX employees?

    “This competitive stance of expansion and exploration, it’s not necessarily a bad thing,” Williams, who also works with the advocacy group Just Space Alliance, said. But, when it comes to a private company using resources that international treaties say do not belong to anyone — “Who’s been brought in and how? Who’s been left out and why? These things matter.”

    Musk’s use of the word “colonization” also belies a long history of Americans and other Western nations enriching themselves by exploiting and enslaving others. And when it comes to colonizing another planet, it’s not just the microbial lifeforms that may exist on Mars that should be concerned. Without clearly defined objectives and agreements, SpaceX’s colony could create a “contentious sphere of conflict,” Williams said.

    “The values that we take with us into space exploration should be front and center,” he added.

    SpaceX did not respond to requests for comment for this story.

    Update: This story has been updated with additional quotes from Robert Zubrin regarding how Mars settlers might pay for their journey.

  • Mystery cylinder on Western Australia beach likely space junk, authorities say | CNN

    Mystery cylinder on Western Australia beach likely space junk, authorities say | CNN

    [ad_1]


    Hong Kong
    CNN
     — 

    A mystery object that washed ashore on Australia’s western coast sparking a flurry of local excitement and speculation over its origin is most likely space junk, police said Tuesday.

    Since it has turned up on a beach at Green Head, a coastal town 250 kilometers (155 miles) north of Perth, the copper-colored cylinder had drawn in curious local residents eager to catch a glimpse of the unidentified object.

    Speculation also erupted online with people posting a host of theories about where it might have come from.

    The Western Australia Police Force said in a statement on Tuesday that the item is believed to be “space debris”, echoing similar comments from the country’s space agency which was working on the same hypothesis.

    Police were initially cautious, throwing up a cordon around the object and telling locals to keep away.

    But in a new update on Tuesday, police said an analysis by the Department of Fire and Emergency Service and Chemistry Centre of Western Australia had found the object to be safe, posing no current risk to the community.

    Police added they were discussing ways with relevant agencies to safely remove and store the object, while working on finalizing their findings.

    But space junk looks the most likely explanation.

    “The object could be from a foreign space launch vehicle and we are liaising with global counterparts who may be able to provide more information,” the Australian Space Agency tweeted on Monday.

    The bulky cylinder, which stands taller than a human, appears to be damaged at one end and is covered with barnacles, suggesting it has spent a significant amount of time at sea before washing up.

    The space agency urged people to avoid handling and moving the object due to its unknown origin and to report any further discovery of suspected debris.

    Police said previously that the item did not appear to originate from a commercial aircraft and vowed to guard it until its removal.

    Alice Gorman, a space archaeologist from Flinders University in Adelaide, said the cylinder is likely the third phase of a polar satellite launch vehicle previously launched by India.

    “It is identical in dimension and materials,” Gorman told CNN, comparing it with launch vehicles used by India since 2010.

    Space rockets are multi-stage, meaning they are made up of various compartments carrying fuel, each of which are dumped in a sequential order when the propellant runs out, with much of the debris falling back to Earth.

    Gorman also said the largely intact color and shape of the cylinder suggests that it did not reach outer space before it detached, sparing it from intense burn with the atmosphere on re-entry. It may have landed in the ocean about five to 10 years ago until a recent deep sea storm pushed it to the shore, she added.

    Gorman said the cylinder runs on solid fuel, which only releases toxic substances under high temperature. But she advised local residents to err on the side of caution.

    “Just as general rule, you don’t touch space junk unless you need to,” she said.

  • India shoots for the moon with historic Chandrayaan-3 mission | CNN

    India shoots for the moon with historic Chandrayaan-3 mission | CNN

    [ad_1]



    CNN
     — 

    India is bidding to become only the fourth country to execute a controlled landing on the moon with the launch Friday of its Chandrayaan-3 mission.

    Chandrayaan, which means “moon vehicle” in Sanskrit, is expected to take off from the Satish Dhawan Space Center at Sriharikota in southern Andhra Pradesh state at 2:30 p.m. local time (5 a.m. ET).

    It’s India’s second attempt at a soft landing, after its previous effort with the Chandrayaan-2 in 2019 failed. Its first lunar probe, the Chandrayaan-1, orbited the moon and was then deliberately crash-landed onto the lunar surface in 2008.

    Developed by the Indian Space Research Organization (ISRO), Chandrayaan-3 is comprised of a lander, propulsion module and rover. Its aim is to safely land on the lunar surface, collect data and conduct a series of scientific experiments to learn more about the moon’s composition.

    Only three other countries have achieved the complicated feat of soft-landing a spacecraft on the moon’s surface – the United States, Russia and China.

    Indian engineers have been working on the launch for years. They are aiming to land Chandrayaan-3 near the challenging terrain of the moon’s unexplored South Pole.

    India’s maiden lunar mission, Chandrayaan-1, discovered water molecules on the moon’s surface. Eleven years later, the Chandrayaan-2 successfully entered lunar orbit but its rover crash-landed on the moon’s surface. It too was supposed to explore the moon’s South Pole.

    At the time, Indian Prime Minister Narendra Modi hailed the engineers behind the mission despite the failure, promising to keep working on India’s space program and ambitions.

    Just before Friday’s launch, Modi said the day “will always be etched in golden letters as far as India’s space sector is concerned.”

    “This remarkable mission will carry the hopes and dreams of our nation,” he said in a Twitter post.

    India has since spent about $75 million on its Chandrayaan-3 mission.

    Modi said the rocket will cover more than 300,000 kilometers (186,411 miles) and reach the moon in the “coming weeks.”

    India’s space program dates back more than six decades, to when it was a newly independent republic and a deeply poor country reeling from a bloody partition.

    When it launched its first rocket into space in 1963, the country was no match for the ambitions of the US and the former Soviet Union, which were way ahead in the space race.

    Now, India is the world’s most populous nation and its fifth largest economy. It boasts a burgeoning young population and is home to a growing hub of innovation and technology.

    And India’s space ambitions have been playing catch up under Modi.

    For the leader, who swept to power in 2014 on a ticket of nationalism and future greatness, India’s space program is a symbol of the country’s rising prominence on the global stage.

    In 2014, India became the first Asian nation to reach Mars, when it put the Mangalyaan probe into orbit around the Red Planet, for $74 million – less than the $100 million Hollywood spent making space thriller “Gravity.”

    Three years later, India launched a record 104 satellites in one mission.

    In 2019, Modi announced in a rare televised address that India had shot down one of its own satellites, in what it claimed was an anti-satellite test, making it one of only four countries to do so.

    That same year ISRO’s former chairman Kailasavadivoo Sivan said India was planning to set up an independent space station by 2030. Currently, the only space stations available for expedition crews are the International Space Station (a joint project between several countries) and China’s Tiangong Space Station.

    The rapid development and innovation has made space tech one of India’s hottest sectors for investors – and world leaders appear to have taken notice.

    Last month, when Modi met US President Joe Biden in Washington on a state visit, the White House said both leaders sought more collaboration in the space economy.

    And India’s space ambitions do not stop at the moon or Mars. ISRO has also proposed sending an orbiter to Venus.

  • Search efforts grow as mission to rescue 5 aboard missing submersible races clock | CNN

    Search efforts grow as mission to rescue 5 aboard missing submersible races clock | CNN

    [ad_1]



    CNN
     — 

    The multinational search efforts for a submersible with five people onboard that disappeared Sunday while diving to view the Titanic’s resting place grew Tuesday as more ships and aircraft joined the mission to find the mariners before their oxygen runs out.

    A spokesperson for the US Navy said the military branch is sending subject matter experts and a “Flyaway Deep Ocean Salvage System” to help in the rescue mission for the commercial submersible, which disappeared Sunday morning and as of Tuesday night, had just over 30 hours of oxygen left.

    The system has the capacity to lift and recover large, bulky and heavy undersea objects, like the small submersible.

    The equipment and personnel were expected to arrive at St. John’s, Newfoundland, by Tuesday night, the spokesperson said.

    The US Coast Guard and the Royal Canadian Air Force are also deploying more aircraft and vessels to aid in the search for the 21-foot submersible. The fleet of assets joining the operation include a Canadian pipe-laying vessel with underwater capabilities, along with other vessels and aircraft.

    Follow live updates

    OceanGate Expeditions says the submersible, known as “Titan,” begins each trip with 96 hours of life support on the vessel. That is “a short amount of time,” said retired Capt. Bobbie Scholley, a former US Navy diver.

    “The hard part is finding the submersible. And once they find the submersible, there are all sorts of situations of how to get that submersible to the surface, and rescue the crew,” Scholley said.

    The international search and rescue operation is “doing everything possible” as part of a “complex search effort” but has so far “not yielded any results,” US Coast Guard Capt. Jamie Frederick told reporters Tuesday at a 1 p.m. ET news conference. The “unique” and “challenging” search effort has brought together “our nations’ best experts,” he said.

    At the time, Frederick estimated the vessel was down to 40 hours of oxygen – and officials do not know whether that’s enough time to rescue those onboard.

    “What I will tell you is, we will do everything in our power to effect a rescue,” he said in response to a question about the oxygen time limit from CNN.

    If searchers locate the submersible deep in the ocean, the mission to recover the craft and any onboard survivors will be complex.

    “There’s very few assets in the world that can go down that deep,” said retired Capt. Chip McCord, whose 30 years of US Navy experience includes overseeing several salvage operations.

    Because of the depth of the ocean floor, a search craft would have to “go up and down like an elevator” rather than cruise the bottom of the sea, he added.

    Searchers have taken the mission below sea level after scouring an area of the ocean’s surface about the size of Connecticut, US Coast Guard District 1 Rear Admiral John Mauger said Tuesday morning. “We now have underwater search capability on scene, and so we’re going to be using that to see if we can locate the submersible in the water,” he told CNN.

    The search zone covers an area about 900 miles east of Cape Cod, Massachusetts, and 13,000 feet deep, Mauger said Monday afternoon. “We are deploying all available assets to make sure that we can locate the craft and rescue the people onboard,” he told reporters.

    The submersible known as “Titan” – roughly the size of a minivan – was carrying one pilot and four “mission specialists” when it lost contact with its mother ship about 1 hour and 45 minutes into its descent, authorities said.

    The submersible is operated by OceanGate Expeditions, a company that organizes a journey to the ocean floor for a price of $250,000, according to an archived version of its website.

    The 23,000-pound Titan is made of highly engineered carbon fiber and titanium and is equipped with repurposed everyday items, including a video game controller used to steer.

    The expedition reflects the ongoing fascination with the Titanic’s wreckage more than a century after it hit an iceberg and sank on its maiden voyage, killing more than 1,500 people. The journey is also part of the growing business of wealthy adventure tourism, along with the space flights of Blue Origin or the rise of guided tours to Mount Everest.

    OceanGate CEO and founder Stockton Rush is among the five onboard, according to a source with knowledge of the mission plan.

    The others are British businessman Hamish Harding; Pakistani billionaire Shahzada Dawood and his son, Sulaiman Dawood; and French diver Paul-Henri Nargeolet, according to CNN reporting.

    OceanGate did not immediately respond to CNN’s request for comment about Rush being aboard.

    OceanGate in a statement on Monday said “every step possible is being taken to bring the five crew members back safely. We are deeply grateful for the urgent and extensive assistance we are receiving from multiple government agencies and deep-sea companies as we seek to reestablish contact with the submersible.”

    In 2018, the Manned Underwater Vehicles committee of the Marine Technology Society penned a letter to Rush, expressing concern over what they referred to as OceanGate’s “experimental approach” of the Titan and its planned expedition to the site of the Titanic wreckage, the New York Times reports.

    “Our apprehension is that the current experimental approach adopted by Oceangate could result in negative outcomes, (from minor to catastrophic) that would have serious consequences for everyone in the industry,” the letter – which was obtained by the Times – reads, in part.

    Specifically, the letter expressed concern over the company’s compliance with a maritime risk assessment certification known as DNV-GL.

    “Your marketing material advertises that the TITAN design will meet or exceed the DNV-GL safety standards, yet it does not appear that Oceangate has the intention of following DNV-GL classrules,” the letter says. “Your representation is, at minimum, misleading to the public and breaches an industry-wide professional code of conduct we all endeavor to uphold.”

    OceanGate has not responded to a request for comment on the letter.

    The effort to locate those on board, meanwhile, has grown by the day. The Coast Guard is searching with aerial and water surface craft, and the Canadian Armed Forces is also deploying aircraft to assist in the search, a spokesperson told CNN.

    The Canadian research vessel Polar Prince, which took the submersible to the wreckage site, is assisting search and rescue efforts, a spokesperson for its co-owner Horizon Maritime told CNN.

    Officials involved in the search have not publicly named those aboard the submersible, but social media posts and friends and family have identified them.

    Action Aviation, an aircraft brokerage based in the United Arab Emirates, in a statement on Tuesday confirmed Harding, its chairman, is on board.

    “Both the Harding Family and the team at Action Aviation are very grateful for all the kind messages of concern and support from our friends and colleagues,” the statement said. “We are thankful for the continued efforts of the authorities and companies that have stepped in to aid in the rescue efforts. We put great faith and trust in their expertise.”

    Harding has an extensive record of adventures: In 2019 he took part in a flight crew that broke the world record for the fastest circumnavigation of the globe via both poles, and in 2020 he became one of the first people to dive to Challenger Deep in the Pacific Ocean, widely believed to be the deepest point in the world’s oceans.

    And last year, he paid an undisclosed sum of money for one of the seats on Blue Origin’s space flight.

    The day before the vessel went missing, Harding wrote of the Titanic mission: “I am proud to finally announce that I joined OceanGate Expeditions for their RMS TITANIC Mission as a mission specialist on the sub going down to the Titanic.”

    A friend told CNN on Tuesday that Harding is “larger than life.”

    “He lives exploration. He is an explorer to the core of his soul,” fellow explorer Jannicke Mikkelsen said. “He has been to the bottom of planet earth in the Mariana Trench … he’s even been in space. We circumnavigated the planet together … the north and south pole, and set the world speed record.”

    Nargeolet was scheduled to be on Sunday’s dive with him, Harding said Saturday in a Facebook post:

    “The team on the sub has a couple of legendary explorers, some of which have done over 30 dives to the RMS Titanic since the 1980s including PH Nargeolet,” Harding wrote, according to CNN news partner CTV News.

    A friend of Nargeolet, Mathieu Johann, told CNN Tuesday the missing submariner is a “hero” and said, “I hope that, right to the end, like in the movies, he’ll reappear very quickly to reassure us all.”

    “What we’re going through right now is this interminable wait,” Johann said.

    Nargeolet is a Titanic expert who has taken the trip every year, completing more than 37 dives to the wreck, according to an archived version of OceanGate Expeditions’ website accessible via the Internet Archive’s Wayback Machine.

    “Something we always think about as explorers and scientists … we’ve always known something like this could happen and now it’s happened,” said David Gallo, a colleague of Nargeolet and the senior adviser for Strategic Initiatives at RMS Titanic Inc. “But we’re still pretty much in shock, the community is. I hope it has a good ending.”

    Further, Shahzada Dawood and his son Sulaiman Dawood, of Pakistan, “embarked on a journey to visit the remnants of the Titanic in the Atlantic Ocean,” their family said Tuesday in a statement. “As of now, contact has been lost with their submersible craft and there is limited information available,” the family said, adding they’re praying for their loved ones’ safe return.

    The incident has left the community of undersea explorers in shock, said David Gallo, who called Nargeolet his “closest colleague. “We’ve always known something like this could happen and now it’s happened … I hope it is a good ending,” Gallo, senior adviser for strategic initiatives at RMS Titanic Inc., told CNN.

    An undated photo shows the OceanGate Titan vessel.

    The OceanGate Expeditions trip began with a 400-nautical-mile journey from St. John’s, Newfoundland, to the Titanic wreck site. There, the submersible started its descent Sunday morning before losing contact with the Polar Prince, a converted ice breaker that was its mother ship.

    The last communication between the vessel and OceanGate staff at the surface came in at 11:47 a.m. The vessel was expected to resurface at 6:10 p.m. but did not do so, and authorities were notified at 6:35 p.m., according to Polar Prince co-owner Miawpukek Maritime Horizon Services.

    Chief Mi’sel Joe of Miawpukek First Nation, which co-owns the Polar Prince, got a call Sunday alerting him that the submersible was two hours overdue and still hadn’t surfaced and communication with it was lost, he said. At that point, requests for search and rescue had gone out, he said.

    “There’s a tremendous amount of concern,” Joe said. “I have anguish that people are going through this. I wish there was more I can do.”

    Unlike a submarine, a submersible needs a mother ship to launch it, has fewer power reserves and can’t stay underwater as long.

    A mother ship can communicate with a submersible “via text messages which are exchanged via a USBL (ultra-short baseline) acoustic system,” according to OceanGate Expeditions’ archived website. The submersible is required to communicate with the ship every 15 minutes or more frequently, if needed, the site says. That USBL system is the only communications link between the submersible and the surface, it adds.

    What we know about the timeline:

    Friday, June 16:

  • The Polar Prince departs St. John’s, NewfoundlandSaturday, June 17:
  • The Polar Prince arrives at the dive siteSunday, June 18:
  • 9 a.m.: The dive operations started
  • 11:47 a.m.: Last communication between vessel and OceanGate surface staff
  • 6:10 p.m.: Originally scheduled resurface time
  • 6:35 pm.: Authorities notified and response operation initiated
  • All times in Atlantic Daylight Time, which is 1.5 hours ahead of Eastern Time
  • Source: Miawpukek Maritime Horizon Services, which co-owns the Polar Prince

While Titan is made of carbon fiber and titanium, some parts are decidedly low-tech.

“It is operated … by a gaming controller, what essentially looks like a PlayStation controller,” said CNN correspondent Gabe Cohen, who sat in Titan in 2018 while reporting on OceanGate Expeditions for CNN affiliate KOMO.

Cohen was surprised by how simple some of the craft’s technology seemed, he said Tuesday on “CNN This Morning.”

It’s a “tiny vessel, quite cramped and small,” Cohen said. “You have to sit inside of it, shoes off. It can only fit five people.”

A Titanic dive takes about 10 hours from start to finish, including the two and a half hours it takes to reach the bottom, the website says. The company calls its clients “mission specialists,” who are trained as crew members in a variety of different roles, including communicating with the topside tracking team, taking sonar scans and opening and closing the vessel’s dome, the archived site says.

Clients do not need previous maritime experience to join as mission specialists, it adds.

In case of an emergency, the submersible is equipped with basic emergency medical supplies and pilots have basic first aid training, according to OceanGate Expeditions’ website.

Everybody is “focused onboard here for our friends,” an expedition participant on the Polar Prince said Monday.

“We have a situation that is now the part of a major Search and Rescue effort, being undertaken by major agencies,” Rory Golden said on Facebook after CNN contacted him. “That is where our focus is right now.”

Hamish Harding posted an image of the submersible to his social media accounts on Saturday.

Deep sea-mapping company Magellan, known for their one-of-a-kind deep sea imagery of the Titanic, is trying to get involved in the search and rescue efforts but a key transport issue is holding them back. Magellan Chairman David Thompson told CNN that his team is familiar with the site of the wreck and received written notice from OceanGate Expeditions to mobilize early Monday and help.

However, they need an aircraft with the ability to transport their deep-sea diving equipment from the UK to Canada to launch their operation. Specifically, he said, they would require the use of a C-17 Globemaster III military jet.

“We know the wreck site, we know the location, and the equipment we are trying to get picked up is the equipment we used to do that scanning of the Titanic,” Thompson said.

Thompson said the US Air Force or UK Royal Airforce have not gotten back to Magellan letting them know if or when a plane can be procured for them to use to transport the equipment they need to Canada to embark on rescue efforts.

Correction: An earlier version of this story incorrectly described Mathieu Johann’s relationship to Nargeolet. He is a friend.

    CNN
     — 

    Giant solar balloons were sent 70,000 feet up in the air to record sounds of Earth’s stratosphere — and the microphones picked up some unexpected sounds.

    The stratosphere is the second layer of Earth’s atmosphere, and its lower level contains the ozone layer that absorbs and scatters the sun’s ultraviolet radiation, according to NASA. The thin, dry air of the stratosphere is where jet aircraft and weather balloons reach their maximum altitude, and the relatively calm atmospheric layer is rarely disturbed by turbulence.

    Daniel Bowman, principal scientist at Sandia National Laboratories in New Mexico, was inspired in graduate school to explore the soundscape of the stratosphere after being introduced to the low-frequency sounds that are generated by volcanoes. Known as infrasound, the phenomenon is inaudible to the human ear.

    Bowman and his friends had previously flown cameras on weather balloons “to take pictures of the black sky above and the Earth far below” and successfully built their own solar balloon.

    He proposed attaching infrasound recorders to balloons to record the sounds of volcanoes. But then he and his adviser Jonathan Lees of the University of North Carolina, Chapel Hill, “realized that no one had tried to put microphones on stratospheric balloons for half a century, so we pivoted to exploring what this new platform could do,” Bowman said. Lees is a professor of Earth, marine and environmental sciences who researches seismology and volcanology.

    The balloons can take sensors twice as high as commercial jets can fly.

    “On our solar balloons, we have recorded surface and buried chemical explosions, thunder, ocean waves colliding, propeller aircraft, city sounds, suborbital rocket launches, earthquakes, and maybe even freight trains and jet aircraft,” Bowman said via email. “We’ve also recorded sounds whose origin is unclear.”

    The findings were shared Thursday at the 184th Meeting of the Acoustical Society of America in Chicago.

    A recording shared by Bowman from a NASA balloon that circled Antarctica contains infrasound of colliding ocean waves, which sounds like continual sighing. But other crackles and rustling have unknown origins.

    Solar balloons captured a multitude of sounds in the second layer of Earth’s atmosphere, including colliding ocean waves — as well as sounds with unidentified origins.

    In the stratosphere, “there are mysterious infrasound signals that occur a few times per hour on some flights, but the source of these is completely unknown,” Bowman said.

    Bowman and his collaborators have conducted research using NASA balloons and other flight providers, but they decided to build their own balloons, each spanning about 19.7 to 23 feet (6 to 7 meters) across.

    The supplies can be found at hardware and pyrotechnic supply stores, and the balloons can be assembled on a basketball court.

    “Each balloon is made of painter’s plastic, shipping tape, and charcoal dust,” Bowman said via email. “They cost about $50 to make and a team of two can build one in about 3.5 hours. One simply brings it out to a field on a sunny day and fills it up with air, and it will carry a pound of payload to about 70,000 ft.”

    The charcoal dust is used inside the balloons to darken them, and when the sun shines on the dark balloons, the air inside them warms up and becomes buoyant. The inexpensive and easy DIY design means the researchers can release multiple balloons to collect as much data as possible.

    “Really, a group of high schoolers with access to the school gym could build a solar balloon, and there’s even a cellphone app called RedVox that can record infrasound,” Bowman said.

    Bowman estimated that he launched several dozen solar balloons to collect infrasound recordings between 2016 and April of this year. Microbarometers, originally designed to monitor volcanoes, were attached to the balloons to record low-frequency sounds.

    The researchers tracked their balloons using GPS, since they can travel for hundreds of miles and land in inconvenient locations.

    The longest flight so far was 44 days aboard a NASA helium balloon, which recorded 19 days worth of data before the batteries on the microphone died. Meanwhile, solar balloon flights tend to last about 14 hours during the summer and land once the sun sets.

    The advantage of the high altitude reached by the balloons means that noise levels are lower and the detection range is increased — and the whole Earth is accessible. But the balloons also present challenges for researchers. The stratosphere is a harsh environment with wild temperature fluctuations between heat and cold.

    “Solar balloons are a bit sluggish, and we’ve wrecked a few on bushes when trying to launch them,” Bowman said. “We’ve had to hike down into canyons and across mountains to get our payloads. Once, our Oklahoma State colleagues actually had a balloon land in a field, spend the night, and launch itself back in the air to fly another whole day!”

    Lessons learned from multiple balloon flights have somewhat eased the process, but now the greatest challenge for researchers is identifying the signals recorded during the flights.

    “There are many flights with signals whose origin we do not understand,” Bowman said. “They are almost certainly mundane, maybe a patch of turbulence, a distant severe storm, or some sort of human object like a freight train — but it’s hard to tell what is going on sometimes due to the lack of data up there.”

    Sarah Albert, a geophysicist at Sandia National Laboratories, has investigated a “sound channel” — a conduit that carries sounds across great distances through the atmosphere — located at the altitudes Bowman studies. Her recordings have captured rocket launches and other unidentified rumblings.

    Sandia National Laboratories geophysicists (from left) Daniel Bowman and Sarah Albert display an infrasound sensor and the box used to protect the sensors from extreme temperatures.

    “It may be that sound gets trapped in the channel and echoes around until it’s completely garbled,” Bowman said. “But whether it is near and fairly quiet (like a patch of turbulence) or distant and loud (like a faraway storm) is not clear yet.”

    Bowman and Albert will continue to investigate the aerial sound channel and try to determine where the stratosphere’s rumbles are originating — and why some flights record them while others don’t.

    Bowman is eager to understand the soundscape of the stratosphere and unlock key features, like variability across seasons and locations.

    It’s possible that helium-filled versions of these balloons could one day be used to explore other planets like Venus, carrying scientific instruments above or within the planet’s clouds for a few days as a test flight for larger, more complex missions.

  • Hundreds of rockets fired at Israel amid deadly IDF airstrikes in Gaza | CNN

    Hundreds of rockets fired at Israel amid deadly IDF airstrikes in Gaza | CNN

    [ad_1]


    Gaza and Jerusalem
    CNN
     — 

    Israel’s army and Palestinian militants exchanged heavy cross-border fire on Wednesday, with hundreds of rockets launched from Gaza towards Israel after the Israel Defense Forces (IDF) carried out deadly strikes on what it says are Islamic Jihad organization targets along the strip.

    The latest violence came after Israeli military airstrikes earlier in the week killed three leaders of the Palestinian militant group and 10 other Palestinian men, women and children in Gaza and led to threats of retaliation.

    In a new update early Thursday, the IDF said it had targeted another Islamic Jihad commander who was a “central figure” in the Palestinian militant group.

    “We just targeted Ali Ghali, the commander of Islamic Jihad’s Rocket Launching Force, as well as two other Islamic Jihad operatives in Gaza,” the IDF said in a tweet, adding that Ghali was “responsible for the recent rocket barrages launched against Israel.”

    Israel has been bombarding the Islamic Jihad’s operatives and infrastructure, using unmanned drones for surveillance as it monitors militant preparations to propel rockets, IDF chief spokesman Rear Adm. Daniel Hagari said Wednesday.

    At least six Palestinians were killed in Wednesday’s airstrikes, the Ministry of Health in Gaza said, revising down its earlier count.

    Hamas, the Palestinian militant movement that runs Gaza, issued a statement Wednesday strongly suggesting that its forces were releasing rockets towards Israel, shortly after the IDF said firmly it believed Hamas was not doing so.

    “The Palestinian resistance with all its factions, led by the Nasser Salah al-Din Brigades, is participating now in a unified manner by teaching the enemy a lesson that it will not forget and confirming that Palestinian blood is not cheap,” said the statement, issued by Muhammad al-Buraim, an official in the joint resistance committees in Palestine.

    The statement appeared designed to reject an assertion by IDF chief spokesman Hagari that the IDF saw only Islamic Jihad, not Hamas, firing rockets.

    Nearly 500 rockets were fired from Gaza towards Israel in the recent barrage, according to the IDF, as of 9:30 p.m. local time. Of those, 153 were intercepted by Israeli missile defenses and 107 fell short, landing in Gaza.

    The IDF said fighter jets and helicopters targeted over 40 rocket and mortar shells launchers belonging to Islamic Jihad terrorist across the Gaza Strip, adding that it is continuing to target launchers and additional posts belonging to the militant organization.

    Civilians in Israel have been asked to act according to the special instructions posted on the National Emergency Portal.

    Israeli Prime Minister Benjamin Netanyahu and other top officials Wednesday downplayed the idea that a ceasefire with Islamic Jihad was imminent, with Netanyahu saying: “The campaign is not over yet.”

    National Security Council chair Tzachi Hanegbi said that rumors of a ceasefire were “premature,” while Defense Minister Yoav Gallant struck a slightly more optimistic note, saying: “I hope we’ll bring it to an end soon, but we’re ready for the option that it will be prolonged.”

    Over half a million Israelis were in or near shelters, the IDF spokesman Hagari said just after 2 p.m. local time (7 a.m. ET) on Wednesday.

    Medics transport a victim to Shifa Hospital following the deadly Israeli airstrikes launched into Gaza on Tuesday.

    International leaders have condemned the hostilities. The United Nations Secretary-General urged all parties to exercise “maximum restraint” over the escalation of violence in Gaza, a statement by Farhan Haq, deputy spokesperson for the Secretary-General, said on Wednesday.

    “The Secretary General condemns the civilian loss of life, including that of children and women, which he views as unacceptable and must stop immediately,” the statement said.

    “Israel must abide by its obligations under international humanitarian law, including the proportional use of force and taking all feasible precautions to spare civilians and civilian objects in the conduct of military operations. “

    The statement continued to say the Secretary-General also condemns the “indiscriminate launch” of rockets from Gaza into Israel, adding it “violates international humanitarian law and puts at risk both Palestinian and Israeli civilians.”

    Qatar has been engaged in “intensive and continuous calls” to stop Israel’s “brutal aggression” on the Gaza Strip to avoid “more losses,” the spokesperson for Qatar’s Ministry of Foreign Affairs Majed Al-Ansari said in a statement on Wednesday.

    Meanwhile, Egyptian state-affiliated XtraNews said there are “intensive efforts” to reach a ceasefire in Gaza, citing Egyptian sources, without clarifying which parties have been communicated with. The news was carried on Egyptian state newspaper’s Al Ahram’s online website.

    Hamas said in a statement that the head of its political bureau, Ismail Haniya, spoke with officials from Egypt, Qatar and the UN.

    Rockets fired from Gaza into Israel streak across the sky on Wednesday.

    The Ministry of Health in Gaza said one person was killed in Wednesday’s attack. It named him as Muhammad Yusuf Saleh Abu Ta’ima, 25, and said he was killed in the bombing east of Khan Younis, in the southern Gaza Strip.

    A CNN producer in Gaza reported explosions in Khan Younis, Rafah and northern Gaza.

    Shortly after, he saw at least six rockets fired from Gaza towards Israel. Sirens warning of incoming rockets sounded in the southern Israeli cities of Sderot and Ashkelon and the Lachish area, all near the Gaza Strip, the Israel Defense Forces said. Sirens later sounded in Tel Aviv, Israel’s main city on the Mediterranean coast, warning of potential incoming rocket fire.

    Several locations in Israel suffered direct hits by rockets from Gaza, authorities said, but there were no immediate reports of casualties. A rocket landed near buildings and caused extensive damage in Ashkelon, pictures distributed by Israel Fire & Rescue Authority showed. A building in Kibbutz Nir Am also was hit, and a rocket landed in the garden of a house in Sderot.

    One of the three Islamic Jihad commanders killed on Tuesday was working on capabilities to launch rockets from the West Bank toward Israel, IDF chief spokesman Hagari said at the time.

    Rockets have never been fired from the West Bank into Israel.

    Islamic Jihad confirmed three of its commanders were killed in the overnight operation along with their wives and children.

    The commanders killed were Jihad Shaker Al-Ghannam, secretary of the Military Council in the al Quds Brigades; Khalil Salah al Bahtini, commander of the Northern Region in the al Quds Brigades; and Ezzedine, one of the leaders of the military wing of the al Quds Brigades in the West Bank, the group said.

    Hagari said the operation had been planned since last Tuesday, when Islamic Jihad fired more than 100 rockets toward Israel following the death of its former spokesman while on hunger strike in an Israeli prison.

    But, the IDF did not have the “operational conditions” until overnight Tuesday.

    The IDF launched a further strike on Tuesday, saying its air force targeted “a terrorist squad” belonging to Islamic Jihad in Khan Younis in the southern Gaza Strip.

    The Palestinian ministry of health in Gaza said two people were killed and two others injured in that attack east of Khan Younis, although they have yet to identify them, bringing the death toll in Gaza to 15 on Tuesday.

    Gaza is one of the most densely packed places in the world, an isolated coastal enclave of almost two million people crammed into 140 square miles.

    Governed by the Palestinian militant group Hamas, the territory is largely cut off from the rest of the world by an Israeli blockade of Gaza’s land, air and sea dating back to 2007. Egypt controls Gaza’s southern border crossing, Rafah.

    Israel has placed heavy restrictions on the freedom of civilian movement and controls the importation of basic goods into the narrow coastal strip.

    CNN
     — 

    Just a few months after NASA introduced the world to the most powerful rocket ever flown to orbit, Elon Musk’s SpaceX is prepared to set off its own creation — which could pack nearly twice the power of anything flown before.

    SpaceX’s vehicle, called Starship, is currently sitting on a launch pad at the company’s facilities on the southern Texas coastline. The company is targeting liftoff at 8 a.m. CT (9 a.m. ET) on Monday, although it has the ability to take off anytime between 8 a.m. CT (9 a.m. ET) and 9:30 a.m. CT (10:30 a.m. ET).

    “I guess I’d like to just set expectations low,” SpaceX CEO Elon Musk said during a Twitter “Spaces” event for his subscribers Sunday evening. “If we get far enough away from launch pad before something goes wrong, then I think I would consider that to be a success. Just don’t blow up the pad.”

    He added: “There’s a good chance that it gets postponed since we’re going to be pretty careful about this launch.”

    It will be SpaceX’s first attempt to launch a fully assembled Starship vehicle, building on a years-long testing campaign.

    Musk has talked about Starship — making elaborate presentations about its design and purpose — for half a decade, and he frequently harps on its potential for carrying cargo and humans to Mars. Musk has even said that his sole purpose for founding SpaceX was to develop a vehicle like Starship that could establish a human settlement on Mars.

    Additionally, NASA has already awarded SpaceX contracts and options worth several billions of dollars to use Starship to ferry government astronauts to the surface of the moon under the space agency’s Artemis program.

    The inaugural flight test will not complete a full orbit around Earth. If successful, however, it will travel about 150 miles above Earth’s surface, well into altitudes deemed to be outer space.

    Starship consists of two parts: the Super Heavy booster, a gargantuan rocket that houses 33 engines, and the Starship spacecraft, which sits atop the booster during launch and is designed to break away after the booster expends its fuel to finish the mission.

    The massive Super Heavy rocket booster will give the first blast of power at liftoff.

    Less than three minutes after takeoff, it’s expected to expend its fuel and separate from the Starship spacecraft, leaving the booster to be discarded in the ocean. The Starship will use its own six engines, blazing for more than six minutes, to propel itself to nearly orbital speeds.

    The vehicle will then complete a partial lap of the planet, reentering the Earth’s atmosphere near Hawaii. It’s expected to splash down off the coast about an hour and a half after liftoff.

    Starship’s ultimate success or failure immensely consequential. Not only is it crucial to SpaceX’s future as a company — it also underpins the United States government’s ambitions for human exploration.

    But it’s not all riding on this inaugural test flight. SpaceX has long established its willingness to embrace mishaps, mistakes and explosions in the name of refining the design of its spacecraft.

    In the lead-up to the first launch of the company’s Falcon Heavy rocket in 2018, which held the title of most powerful rocket before NASA’s SLS took flight last year, Musk foresaw only a 50-50 chance of success.

    “People (came) from all around the world to see what will either be a great rocket launch or the best fireworks display they’ve ever seen,” Musk told CNN at the time.

    The inaugural Falcon Heavy launch was ultimately successful.

    Development of Starship has been based at SpaceX’s privately held spaceport about 40 minutes outside Brownsville, Texas, on the US-Mexico border. Testing began years ago with brief “hop tests” of early spacecraft prototypes. The company began with brief flights that lifted a few dozen feet off the ground before evolving to high-altitude flights, most of which resulted in dramatic explosions as the company attempted to land them upright.

    One suborbital flight test in May 2021, however, ended in success.

    SpaceX workers on February 8 make final adjustments to Starship's orbital launch mount, and the booster's matrix of Raptor engines within, ahead of the company's engine test.

    Since then, SpaceX has also been working to get its Super Heavy booster prepared for flight. The massive, 230-foot-tall (69-meter-tall) cylinder is packed with 33 of the company’s Raptor engines.

    Fully stacked, Starship and Super Heavy stand about 400 feet (120 meters) tall.

    SpaceX has been waiting more than a year to get FAA approval for this launch attempt.

    The company, and federal regulators tasked with certifying SpaceX launches won’t pose risks to people or property in the area surrounding the launch site, have faced significant pushback from the local community, including from environmental groups.

    But the Federal Aviation Administration, which licenses commercial rocket launches, announced Friday, April 14, that it granted the company’s request for an uncrewed flight test of the rocket out of the SpaceX facilities in South Texas.

    “After a comprehensive license evaluation process, the FAA determined SpaceX met all safety, environmental, policy, payload, airspace integration and financial responsibility requirements,” the agency said in a statement.

    During a call with reporters last week, an FAA official, who declined to be named for publication, said that the agency has been overseeing SpaceX’s compliance with the mitigating actions, some of which are still in the works, even as the company prepares for launch.

    The FAA official said government personnel will be on the ground to ensure SpaceX complies with its license during the test launch.

    SpaceX’s contract with NASA to use Starship for the space agency’s Artemis III moon landing later this decade leaves much of Starship’s development work to SpaceX. A $2.9 billion deal, inked in April 2021, was awarded to SpaceX over several competitors. It was later expanded to include a second lunar landing mission in 2027.

    NASA has been working over the past year to hash out a work flow between the space agency and SpaceX. It’s a dynamic the two organization have had to iron out in previous SpaceX-NASA projects, including an ongoing partnership that uses SpaceX’s Dragon spacecraft to get astronauts to and from the International Space Station.

    A moon mission, however, involves more powerful and complex hardware.

    NASA is not, however, involved in planning the flight profile for this test flight or directing SpaceX on what to do, according to Lisa Hammond, NASA’s associate program manager of the Human Landing System at Johnson Space Center in Houston.

    Hammond did not share a specific checklist of tests or flights that NASA hopes to see before Starship is entrusted with a moon landing mission.

    “I would not put it with a number,” she said, adding that the Artemis II mission, slated for next year, will see humans fly atop the SLS rocket after only one uncrewed test flight.

    “The confidence comes in the design, the confidence comes in the safety of the vehicle for the crew,” Hammond said.

    SpaceX president Gwynne Shotwell previously said she hopes the company will conduct more than 100 orbital test flights of Starship before putting humans on board, as the company will need to do in order to help NASA carry out its moon landing with the Artemis III mission, slated for 2025.

    “I think that would be a great goal,” Shotwell said Wednesday, when asked whether that target was still feasible. “I don’t think we will do 100 flights of Starship next year, but maybe (in) 2025 we will do 100 flights.”

    NASA’s current timeline targets 2025 for the first lunar landing mission, which will see astronauts transfer from their Orion capsule, which will launch atop a NASA Space Launch System rocket, and into a Starship spacecraft already in lunar orbit. It will be the Starship vehicle that ferries the crew down to the lunar surface.

    It’s not clear, however, if 2025 is feasible. NASA’s inspector general has already suggested it is not. Delays, according to comments from the inspector general in March 2022, could revolve around Starship.

     — 

    SpaceX has cleared the final regulatory hurdle standing before the inaugural launch of its Starship rocket — the most powerful rocket ever constructed.

    The Federal Aviation Administration, which licenses commercial rocket launches, announced Friday that it granted the company’s request for an uncrewed flight test of the rocket out of the SpaceX facilities in South Texas. The vehicle, which has already undergone preflight ground testing, is poised to take off as soon as Monday.

    “After a comprehensive license evaluation process, the FAA determined SpaceX met all safety, environmental, policy, payload, airspace integration and financial responsibility requirements,” the agency said in a statement.

    Earlier Friday, the FAA issued an air traffic restriction for the area surrounding the launch. The Notice to Air Missions, or NOTAM, orders planes and other air traffic to steer clear of the launch area — which lies due East of Brownsville, Texas — on Monday between 7 a.m. and 10:05 a.m. CT (8 a.m. and 11:05 a.m. ET).

    This will be SpaceX’s first attempt to put Starship into orbit, building on a yearslong testing campaign to work out the design of the rocket.

    SpaceX CEO Elon Musk has talked about Starship for about a decade, making elaborate presentations about its design and describing it as the vehicle that underpins SpaceX’s founding purpose: sending humans to Mars for the first time.

    Additionally, NASA has already awarded SpaceX contracts and options — worth more than $3 billion — to use Starship to ferry government astronauts to the surface of the moon under the space agency’s Artemis program.

    Starship consists of two parts: the Super Heavy booster, a gargantuan rocket that houses 33 engines, and the Starship spacecraft, which sits atop the booster during launch and is designed to break away after the booster expends its fuel to finish the mission.

    On this flight, the rocket booster will be discarded into the ocean shortly after liftoff. In future flights, however, SpaceX plans to recover the vehicle by guiding it to an upright landing back at the launch site. The Starship spacecraft will complete nearly one full lap of the planet, ending its flight with a splashdown off Hawaii.

    Development of Starship has been based at SpaceX’s privately held spaceport about 40 minutes outside Brownsville, Texas, on the US-Mexico border.

    In June, the FAA granted SpaceX one key approval for launching Starship, though it laid out a list of “mitigating actions” the company would need to take before the first launch.

    During a call with reporters this week, an FAA official, who declined to be named for publication, said that the agency has been overseeing SpaceX’s compliance with the mitigating actions, some of which are still in the works, even as the launch license is issued.

    The FAA official said government personnel will be on the ground to ensure SpaceX complies with its license during the test launch.

  • Dozens of rockets fired from Lebanon into Israel after raids on al-Aqsa mosque | CNN

    Dozens of rockets fired from Lebanon into Israel after raids on al-Aqsa mosque | CNN

    [ad_1]


    Jerusalem
    CNN
     — 

    Dozens of rockets were fired from Lebanon into Israel on Thursday, the Israeli military said, in a major escalation that comes amid regional tensions over Israeli police raids at the al-Aqsa mosque in Jerusalem.

    Some 34 rockets were launched from Lebanese territory into Israeli territory, the Israel Defense Forces (IDF) said, with the majority intercepted but six landing in Israel.

    It was the largest such attack since a 2006 war between the two countries left around 1,200 Lebanese people and 165 Israelis dead.

    Videos posted on social media showed rockets streaking through the skies over northern Israel, and the sounds of explosions in the distance.

    The country closed its northern airspace in the wake of the barrage. No deaths were reported, and it is not yet known which group in Lebanon launched the rockets.

    Israel said it would “decide on the place and time” of its response, an IDF defense official who asked not to be named told CNN. An Israeli military spokesman said they believed a Palestinian militant group was behind the attack, not the Lebanese militant group Hezbollah.

    The Lebanese army confirmed a number of a rockets were launched from the country’s south, but did not detail who had fired them. It said on Twitter that a unit had found “missile launchers and a number of rockets intended for launch” in the vicinity of the Lebanese towns of Zibqin and Qlaileh, and was “currently working to dismantle them.”

    Hezbollah has not yet commented on the incident. It comes a day after Ismail Haniyeh, the leader of the Palestinian militant group Hamas, arrived in Beirut for meetings with Hezbollah officials.

    Tensions are sky-high in the region after Israeli police stormed the al-Aqsa mosque in Jerusalem on two separate occasions Wednesday, as Palestinian worshipers offered prayers during the holy month of Ramadan.

    Footage from inside the mosque showed Israeli officers beating people with their batons and rifle-butts, then arresting hundreds of Palestinians. Israeli police said they entered the mosque after “hundreds of rioters” tried to barricade themselves inside.

    The incident, which was met with widespread condemnation from the Arab and Muslim world, sparked retaliatory rocket fire from Gaza into Israel.

    Jordan’s Foreign Minister Ayman Safadi told CNN “we are at a very dangerous moment.”

    “What we see unfolding on the Lebanese border is obviously a consequence, a reaction to what we saw happening in al-Aqsa [mosque].” Safadi said.

    Trails from rockets can be seen over the skies of northern Israel in this video screengrab, as authorities raised concerns over increased tensions between Israel and Lebanon.

    Lebanon and Israel are considered enemy states, but a truce between them has largely held since the 2006 war.

    There have been several small-scale rocket attacks from Lebanon in recent years that have prompted retaliatory strikes from Israel. Few casualties were reported in those incidents, with the largest death toll in an exchange of fire in 2015 that left two Israeli soldiers and a Spanish peacekeeper dead. Palestinian factions in Lebanon were believed to be behind those rocket attacks.

    The 2006 conflict was the biggest flare-up between Lebanon and Israel since 1982. Around 1,200 Lebanese people and 165 Israelis died in an exchange of fire that involved a nationwide Israeli aerial assault, and a naval and aerial blockade. Hezbollah fired many rounds of rockets reaching deep into Israeli territory during the conflict.

    The Israeli military pinned the blame for the rockets on either Hamas or the Palestinian Islamic Jihad, with international spokesman Lt. Col. Richard Hecht saying the IDF assumed that “Hezbollah knew about it, and Lebanon also has responsibility.”

    But he emphasized several times that the IDF viewed the attack as having come from a Palestinian source, and that it did not represent a widening of the conflict to actors outside of the direct Israeli-Palestinian conflict, raising hopes that tensions could be ratcheted down after the incident.

    The Lebanese foreign ministry also said it was ready to cooperate with the United Nations and take steps to “restore calm and stability” in the south, while calling on “the international community to put pressure on Israel to stop escalation,” the state-owned National News Agency reported.

    The IDF has been concerned for some time about an escalation on the Lebanese border, and hosted a high-level seminar in the spring of 2022 to brief journalists and policy makers about it.

    The UN peacekeeping mission in Lebanon (UNIFIL) said Thursday’s escalation of violence between Lebanon and Israel was “extremely serious.”

    UNIFIL also said it has directed its personnel stationed at the border between the two countries to move to air raid shelters, as a “common practice.”

    The White House said it was “extremely concerned by the continuing violence and we urge all sides to avoid further escalation.”

  • Israeli police storm al-Aqsa mosque during Ramadan prayers, sparking rocket fire from Gaza | CNN

    Israeli police storm al-Aqsa mosque during Ramadan prayers, sparking rocket fire from Gaza | CNN

    [ad_1]



    CNN
     — 

    Israeli police stormed the al-Aqsa mosque in Jerusalem, one of Islam’s holiest sites, during Ramadan prayers early Wednesday, arresting hundreds of Palestinians and sparking retaliatory rocket fire from militants in Gaza.

    Footage shared on social media showed Israeli officers striking screaming people with batons inside the darkened building. Eyewitnesses told CNN that police had smashed doors and windows to enter the mosque and deployed stun grenades and rubber bullets once inside. Video shared by Israeli police show forces holding riot shields up as fireworks were launched back at them, ricocheting off the walls.

    Israeli police said in a statement that its forces entered al-Aqsa after “hundreds of rioters and mosque desecrators (had) barricaded themselves” inside.

    “When the police entered, stones were thrown at them, and fireworks were fired from inside the mosque by a large group of agitators,” according to the statement.

    The Palestinian Red Crescent in Jerusalem said at least 12 people were injured during clashes in and around the mosque, and at least three of the injured were transferred to hospital, some with injuries from rubber bullets.

    The Red Crescent added that at one point its ambulances were targeted by police and were prevented from reaching the injured.

    The incident drew condemnation from across the Arab and Muslim world. Jordan’s Ministry of Foreign Affairs condemned the Israeli police actions “in the strongest terms,” and called on Israel to immediately remove its forces from the mosque. Egypt’s Foreign Ministry also condemned the “storming” of the mosque by police, saying it had caused “numerous injuries among worshipers and devotees” and was “in violation of all international laws and customs.”

    Police said they arrested and removed more than 350 people in the mosque, and that one Israeli police officer was wounded in the leg by stones.

    Images shared on social media showed dozens of detained people lying facedown on the floor of the mosque with their legs and arms bound behind their backs, and others with their hands tied being led into a vehicle.

    Al-Aqsa has seen hundreds of thousands of worshipers offer prayers during the Muslim holy month of Ramadan this year. Jews are set to celebrate Passover on Wednesday evening.

    Over the last two weeks, there have been calls by Jewish extremist groups to slaughter goats at the mosque compound as part of an ancient Passover holiday ritual that is no longer practiced by most Jews. A greater number of Muslim worshipers stayed in the mosque after calls came to prevent those attempts.

    Last week, a Palestinian man was shot and killed by Israeli police at the entrance of the compound. Palestinian and Israeli sources disputed the circumstances that led to the killing of 26-year-old Muhammad Al-Osaibi.

    The mosque compound, frequently a flashpoint in tensions, is home to one of Islam’s most revered sites but also the holiest site in Judaism, known as the Temple Mount.

    The compound reopened for prayers shortly after.

    In a statement Wednesday, Palestinian Authority Prime Minister Mohammad Shtayyeh condemned the actions of the Israeli police, saying: “What is happening in Jerusalem is a major crime against worshipers.”

    “Israel does not want to learn from history, that al-Aqsa is for the Palestinians and for all Arabs and Muslims, and that storming it sparked a revolution against the occupation,” Shtayyeh added.

    The Israel Defense Forces (IDF) said Wednesday that nine rockets were fired from Gaza Strip toward Israel after the incident in Jerusalem.

    “Following the previous report regarding the sirens which sounded in Sderot, five rockets were fired from the Gaza Strip into Israeli territory,” said the IDF. “Four of them were intercepted by the aerial defense array.”

    The IDF also said four additional rockets launched from Gaza toward Israel but landed in open space.

    “Following the additional sirens that sounded in the surroundings of the Gaza Strip, four rockets were launched from the Gaza Strip that landed in open areas. No interceptors were launched according to protocol,” the IDF added.

    Ismail Haniyeh, the leader of Hamas, the militant group that runs Gaza, said in a statement that “the current Israeli occupation’s crimes at the al-Aqsa mosque are unprecedented violations that will not pass.”

    Later on Wednesday, the Israeli military said its fighter jets had struck weapons manufacturing and storage sites in the Gaza Strip belonging to Hamas.

    “This strike was carried out in response to rockets fired from the Gaza Strip toward Israeli territory earlier,” it said in a statement.

    Last year was the deadliest for both Palestinians in the occupied West Bank and for Israelis in nearly two decades, CNN analysis of official statistics on both sides showed.

    And this year has seen a violent beginning, too. At least 90 Palestinians have been killed, according to Palestinian Ministry of Health statistics. In addition to suspected militants being targeted by Israeli forces, the dead include Palestinians killing, wounding or attempting to kill Israeli civilians, people clashing with Israeli security and bystanders, CNN records show.

    In the same period, at least 15 Israelis have been killed in attacks by Palestinians in Israel and the West Bank, CNN records show – 14 civilians and a police officer who was hit by friendly fire after being stabbed by a Palestinian teenager while inspecting bus passengers.

    CNN
     — 

    Four astronauts — including three Americans and one Canadian — will be tapped by NASA to complete a generation-defining mission to the moon’s orbit, returning humans to deeper into the solar system than has been reached in five decades.

    On Monday, the public will finally learn the crew members’ names.

    Scheduled to launch in 2024, Artemis II will be the program’s first crewed mission to orbit the moon, flying farther into space than any humans since the Apollo program. It will pave the way for the Artemis III crew to walk on the moon in 2025, all aboard the world’s most powerful rocket and at a price tag that by then will approach $100 billion.

    Following months of closed-door decision making, NASA officials plan to unveil the names of the crew members in a ceremony scheduled for Monday at 11 am ET.

    Though officials have remained tight-lipped about their choices, CNN previously spoke with nearly a dozen current and former NASA officials and astronauts to pull back the curtain on the secretive selection process.

    Reid Wiseman, a 47-year-old decorated naval aviator and test pilot who was first selected to be a NASA astronaut in 2009, is at the top of the list, according to CNN’s prior reporting.

    Wiseman served as chief of the astronaut office until November 2022. While the chief is not permitted to fly while holding the post, they are able to wrangle the best flight assignments upon stepping down, an “acknowledged perk” of the job, according to former NASA astronaut Garrett Reisman.

    Before stepping down as astronaut chief, Wiseman was also responsible for the decision to broaden the pool of astronauts eligible to fly in order to include himself. While NASA had initially deemed 18 astronauts to be the “Artemis Team” and eligible to fly on moon missions, Wiseman expanded the group of candidates to all 41 active NASA astronauts.

    People familiar with the process also told CNN that along with Wiseman, there are a handful of other candidates atop the list:

    • Randy Bresnik, 55, is also a decorated naval aviator and test pilot who flew combat missions in support of Operation Iraqi Freedom. He has flown two missions to the International Space Station: one on the Space Shuttle, another on a Russian Soyuz spacecraft. Bresnik is often mentioned as a top contender for Artemis because, since 2018, he has overseen the astronaut office’s development and testing of all rockets and spacecraft that will be used in the Artemis missions.
    • Anne McClain, 43, is a decorated army pilot and West Point graduate who flew more than 200 combat missions in support of Operation Iraqi Freedom and went on to graduate from the US Naval Test Pilot School in 2013, the same year she was selected to be a NASA astronaut. After launching on a Russian Soyuz spacecraft in 2018, she spent more than 200 days at the International Space Station and served as the lead of two spacewalks.
    • Stephanie Wilson is the most senior astronaut on this list. The 56-year-old joined NASA’s 1996 astronaut class, and she served as a mission specialist on three Space Shuttle flights, including the first flight after the 2003 Columbia disaster, which killed seven astronauts.
    • Christina Koch, 44, is a veteran of six spacewalks. She holds the record for the longest single spaceflight by a woman, with a total of 328 days in space. Koch is also an an electrical engineer who helped develop scientific instruments for multiple NASA mission. She’s also spent a year at the South Pole, an arduous stay that could well prepare her for the intensity of a moon mission.
    • Jessica Meir is 45-year-old biologist with a doctorate from the Scripps Institution of Oceanography. She was a member of a NASA Extreme Environment Mission Operations (NEEMO) mission in 2002, which involved spending days in an underwater research facility, and, in 2016, completed a two-week caving mission in Italy.

    Koch and Meir together conducted the first three all-female spacewalks in 2019 and 2020.

    Rounding out the Artemis II crew will be one astronaut from Canada, terms that were cemented in a 2020 treaty between the two countries.

    The Canadian Space Agency’s currently has a cadre of just four astronauts, but among them, Jeremy Hansen has generated the most buzz, according to CNN’s reporting. Hansen was selected to be an astronaut almost 14 years ago, but he’s still waiting for his first flight assignment. The 47-year-old fighter pilot recently became the first Canadian to be put in charge of training for a new class of NASA astronauts.

    NASA has also previously committed to selecting a crew with racial, gender and professional diversity.

    Those criteria have not historically been the case for high-profile missions. Going back to the Gemini era, astronauts selected for inaugural crewed missions have been only White and male, and typically come from a background as a military test pilot — a profile notably characterized in the 1979 book “The Right Stuff” by Tom Wolfe.

    That has held true through NASA’s most recent inaugural crewed flight, of SpaceX’s Crew Dragon capsule to the International Space Station in 2020, which included former military test pilots Bob Behnken and Doug Hurley.

    And it may hold mostly true for the Artemis II mission as well: Nearly a dozen current and former NASA officials and astronauts told CNN they anticipated multiple test pilots being named.

    However, if Wiseman, a White man, is selected, that means the other spots will almost certainly need to go to at least one woman and at least one person of color.

    The Artemis II mission will build on Artemis I, an uncrewed test mission that sent NASA’s Orion capsule on a 1.4 million-mile voyage to lap the moon that concluded in December. The space agency deemed that mission a success and is still working to review all the data collected.

    If all goes to plan, Artemis II will take off around November 2024. The crew members, strapped inside the Orion spacecraft, will launch atop a NASA-developed Space Launch System rocket from NASA’s Kennedy Space Center in Florida.

    The journey is expected to last about 10 days and will send the crew out beyond the moon, potentially further than any human has traveled in history, though the exact distance is yet to be determined.

    The “exact distance beyond the Moon will depend on the day of liftoff and the relative distance of the Moon from the Earth at the time of the mission,” NASA spokesperson Kathryn Hambleton said via email.

    After circling the moon, the spacecraft will return to Earth for a splashdown landing in the Pacific Ocean.

    Artemis II is expected to pave the way for the Artemis III mission later this decade, which NASA has vowed will put the first woman and person of color on the lunar surface. It will also mark the first time humans have touched down on the moon since the Apollo program ended in 1972.

    The Artemis III mission is expected to take off later this decade. But much of the technology the mission will require, including spacesuits for walking on the moon and a lunar lander to ferry the astronauts to the moon’s surface, is still in development.

    NASA is targeting a 2025 launch date for Artemis III, though the space agency’s inspector general has already said delays will likely push the mission to 2026 or later.

     — 

    The four astronauts who make up the Crew-5 team aboard the International Space Station began their return trip home Saturday morning, marking the end of a five-month stay in space.

    The SpaceX Crew Dragon capsule disembarked from the space station at 2:20 am ET, beginning the final leg of the astronauts’ journey. The spacecraft is set to splash down off Florida at around 9:02 p.m. ET Saturday.

    Rescue ships will be awaiting the team’s arrival, ready to haul the capsule out of the ocean and allow the crew to disembark, giving the astronauts their first breath of fresh air in nearly 160 days. Shortly afterward, the crew will depart for NASA Johnson Space Center in Houston.

    The four crew members — NASA astronauts Nicole Mann and Josh Cassada, astronaut Koichi Wakata of JAXA, or Japan Aerospace Exploration Agency, and cosmonaut Anna Kikina of the Russian space agency Roscosmos — launched to the space station aboard a SpaceX Crew Dragon capsule this past October. They’ve spent the past few months carrying out research experiments and keeping up with maintenance of the two-decade-old orbiting laboratory.

    And for the past few days, the four have been handing off operations to the Crew-6 team of astronauts who arrived at the space station on March 3.

    Mann, a registered member of the Wailacki tribe of the Round Valley reservation, became the first Native American woman to travel into orbit. Like the other astronauts, she devoted time on her journey to public outreach, some of which focused on inspiring Indigenous children. During one outreach event in November 2022, Mann showed off a dream catcher — a traditional totem for Native Americans meant to ward off bad dreams — that she took with her to the space station.

    “I am very proud to represent Native Americans and my heritage,” Mann told reporters before launch. “I think it’s important to celebrate our diversity and also realize how important it is when we collaborate and unite, the incredible accomplishments that we can have.”

    Kikina’s participation in this flight came as part of a ride-sharing agreement by NASA and Roscosmos in July 2022. Despite geopolitical tensions between the United States and Russia as the war in Ukraine has escalated, NASA has repeatedly said its partnership with Roscosmos is vital to continuing the space station’s operations and the valuable scientific research carried out on board.

    The journey marked the first trip to space for Mann, Cassada and Kikina.

    Wakata previously flew on NASA’s space shuttle flights and Russia’s Soyuz spacecraft. This trip was the Japanese astronaut’s fifth spaceflight mission.

    CNN
     — 

    Japan’s maiden launch of its new flagship space rocket ended in failure on Tuesday when controllers issued a destruct command just 15 minutes after liftoff, the country’s space agency said.

    “A destruct command has been transmitted to H3 around 10:52 a.m. (Japan Standard Time), because there was no possibility of achieving the mission,” a statement from the Japan Aerospace Exploration Agency (JAXA) said.

    A report from public broadcaster NHK said the second stage of the H3 rocket did not ignite.

    The rocket, which took off from the Tanegashima Space Center in southern Japan, was carrying the Advance Land Observation Satellite-3 (ALOS-3), a ground-mapping and imaging orbiter that the space agency said was planned to become a key tool in disaster management efforts.

    ALOS-3 “would cover all of the land areas of not only Japan but also across the whole world,” it said.

    Tuesday’s failure occurred on JAXA’s second attempt to launch the H3. On February 17, two secondary booster engines strapped to the side of the space vehicle did not ignite on the launch pad and the H3 failed to take off.

    The space agency has touted the H3 as the successor to Japan’s H-2A and H-2B rockets, with flexible configurations based on what it would need to lift into orbit. It has previously touted the expected ability of the H3 to launch both government and commercial missions.

    JAXA said the H3 would be more economical than many other launch vehicles because its uses “commercial-off-the-shelf products of other domestic industries such as the automobile industry rather than products exclusive to space use.”

    “With several configurations, the H3 offers performance and price suitable for purposes of each satellite,” it said, adding that it was looking for regular launches over the long term.

    “We are aiming to create an operational world where Japanese industrial base can be underpinned by steadily launching the H3 six times or so annually for 20 years,” JAXA said.

    Mitsubishi Heavy Industries is the prime contractor for the rocket. NHK reported that JAXA and Mitsubishi have spent more that $1.5 billion on the project since its inception nine years ago.

    CNN
     — 

    Russia is gearing up to launch a Soyuz spacecraft to the International Space Station that will replace a capsule that sprang a coolant leak in December, leaving two cosmonauts and one NASA astronaut without a ride home.

    Liftoff of the capsule, called the Soyuz MS-23, is expected to occur out of Russia’s Baikonur Cosmodrome launch site in Kazakhstan on Thursday at 7:24 p.m. ET, which is 5:24 a.m. Friday local time. NASA will air coverage of the event beginning at 7 p.m. ET Thursday.

    The uncrewed spacecraft will spend two days in orbit, maneuvering toward the orbiting laboratory. It’s expected to dock with the Poisk module — which is on the space station’s Russian-run portion — just after 8 p.m. ET Saturday.

    The Soyuz MS-23 will be the return vehicle for cosmonauts Sergey Prokopyev and Dmitri Petelin and NASA astronaut Frank Rubio, all of whom traveled to the space station aboard the Soyuz MS-22 capsule in September.

    About two months into the three men’s journey, the MS-22 experienced a coolant leak, leaving the cabin at temperatures deemed unsafe for the crewmates. The Russian space agency Roscosmos and NASA quickly worked to establish plans to send a replacement vehicle. Roscosmos officials said they had determined that the leak resulted from a small hole caused by an impact with a micrometeoroid.

    Plans to launch the rescue vehicle, however, were drawn into question when a Russian cargo ship, called Progress, experienced a similar coolant leak after docking with the space station on February 11. Three days later, Roscosmos had said in a post on the social media site Telegram, that it would delay the Soyuz MS-23 launch until at least March while the agency investigated the cause of the Progress vehicle’s coolant leak.

    On Tuesday, however, Roscosmos said in an updated Telegram post that it had determined the cause of the Progress spacecraft leak was “external influences.”

    “The Russians are continuing to take a very close look at both the Soyuz and the Progress coolant leaks,” Dana Weigel, the space station’s deputy manager for NASA, said during a Wednesday briefing.

    “They formed a state commission that is assessing the anomalies,” she added, noting that the team is analyzing potential causes from the time the capsules launched through their journey in orbit.

    Originally, Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub and NASA astronaut Loral O’Hara were expected to launch to the space station on March 16 aboard MS-23.

    Instead, Prokopyev, Petelin and Rubio’s time will be extended on the space station until they can return to Earth aboard Soyuz MS-23 later this year. That return could happen in September, according to a report from Russia state-run media outlet TASS.

    If that timeline holds, the three crewmates will have extended their expected six-month stay in space to about one year.

    When asked about the extended stay, Joel Montalbano, the space station’s program manager for NASA, said the crew remains in good health and there is no reason to expedite their journey home.

    The crew is “willing to help wherever we ask,” Montalbano said during a January 11 news conference. “They’re excited to be in space, excited to work and excited to do the research that we do on orbit. So they are ready to go with whatever decision that we give them.”

    He added, “I may have to fly some more ice cream to reward them.”

    The launch of the Soyuz MS-23 spacecraft comes just days before NASA and SpaceX will launch their Crew-6 mission. Expected to lift off early Monday morning, Crew-6 will carry NASA astronauts Stephen Bowen and Warren “Woody” Hoburg as well as Sultan Alneyadi, an astronaut with the United Arab Emirates, and Roscosmos cosmonaut Andrey Fedyaev.

    Shortly after those four arrive at the space station, NASA’s Crew-5 astronauts will return home from their five-month stay there aboard the SpaceX Crew Dragon capsule. NASA officials said this week that the coolant leaks experienced on the Soyuz and Progress vehicles would not have any impact on the SpaceX missions and that no similar issues were discovered on Crew Dragon vehicles.

  • Palestinian man killed and 13 injured in Israeli raid in West Bank, say Palestinian officials | CNN

    Palestinian man killed and 13 injured in Israeli raid in West Bank, say Palestinian officials | CNN

    [ad_1]



    CNN
     — 

    A Palestinian man was killed and 13 were injured in an Israeli raid in Nablus early Monday, Palestinian health officials said, in what Israeli authorities said was an operation to arrest suspects in the fatal shooting of an Israeli soldier last year.

    The Palestinian Ministry of Health said Amir Ihab Bustami, 21, “was shot by the Israeli occupation soldiers and killed at dawn today in Nablus.”

    Six people were wounded by live bullets during the raid in Nablus and seven others were injured “as a result of the army’s pursuit of them,” the Palestinian Red Crescent said. The agency said one person was hospitalized, and that they had also handled 75 cases of tear gas inhalation.

    The Israeli military said the overnight raid was in response to the killing of Ido Baruch in an attack near the settlement of Shavei Shomron in the occupied West Bank on October 11, 2022.

    “[Israeli forces] apprehended the assailants Obkamel Guri and Asama Tuille, from Nablus, who carried out the shooting attack during which Staff Sergeant Ido Baruch was killed,” the Israel Defense Forces (IDF) said in a statement on Monday. “The forces also apprehended three additional suspects who were with the assailants.”

    The Israeli forces exchanged fire with the suspects and confiscated two rifles at an apartment in Nablus, the IDF said, adding that two of the suspects were injured during the raid.

    Lion’s Den, a Palestinian militant group that emerged in Nablus last year, claimed responsibility for the killing of Baruch. The group put out a statement Monday saying it had lured Israeli soldiers into an ambush in Nablus and killed them, but there was no evidence to support that claim. The IDF said no Israeli injuries were reported in the raid.

    The official Palestinian news agency WAFA reported that Israeli forces “surrounded one of the residential buildings” in Nablus and heavy gunfire and an explosion were heard.

    Separately, the Israeli military launched airstrikes in Gaza, targeting “an underground complex” belonging to Hamas for manufacturing rockets, the Israel Defense Forces (IDF) said in a statement early Monday. The airstrikes came after a rocket was launched from Gaza into Israel on Saturday, which the IDF said was intercepted.

    Hamas confirmed in a statement that one of its sites was hit in West Gaza on Monday. Israeli warplanes “launched about 10 air raids targeting a site of the resistance,” al-Qassam Brigades, the armed wing of Hamas, said in a statement early Monday, adding that there were no casualties.

    Following the strikes, four rockets were launched from Gaza into Israel, according to a later statement by the IDF that said it struck Hamas military posts in response.

  • China wants to dominate the ‘near space’ battlefield. Balloons are a key asset | CNN

    China wants to dominate the ‘near space’ battlefield. Balloons are a key asset | CNN

    Hong Kong
    CNN
     — 

    In China’s eyes, the newest superpower battlefield sits between 12 and 60 miles above the Earth’s surface in a thin-aired layer of the atmosphere it calls “near space.”

    Lying above the flightpaths of most commercial and military jets and below satellites, near space is an in-between area for spaceflight to pass through – but it is also a domain where hypersonic weapons transit and ballistic missiles cross.

    China has paid close attention to other countries’ developments in this region, which has been hailed by Chinese military experts as “a new front for militarization” and “an important field of competition among the world’s military powers.”

    In addition to developing high-tech vessels such as solar-powered drones and hypersonic vehicles, China is also reviving a decades-old technology to utilize this area of the atmosphere – lighter-than-air vehicles. They include stratospheric airships and high-altitude balloons – similar to the one identified over the continental United States and shot down on Saturday.

    China maintains the balloon is a civilian research airship, despite claims by US officials that the device was part of an extensive Chinese surveillance program.

    While questions remain about that incident, an examination of Chinese state media reports and scientific papers reveal the country’s growing interest in these lighter-than-air vehicles, which Chinese military experts have touted for use toward a wide range of purposes, from communication relay, reconnaissance and surveillance to electronic countermeasures.

    Chinese research on the high-altitude balloons dates back to the late 1970s, but over the past decade there’s been renewed focus on using older technology equipped with new hardware as major powers around the world have bulked up their capabilities in the sky.

    “With the rapid development of modern technology, the space for information confrontation is no longer limited to land, sea, and the low altitude. Near space has also become a new battlefield in modern warfare and an important part of the national security system,” read a 2018 article in the PLA Daily, the official newspaper of the People’s Liberation Army (PLA).

    And a range of “near-space flight vehicles” will play a vital role in future joint combat operations that integrate outer space and the Earth’s atmosphere, the article said.

    Chinese leader Xi Jinping has urged the PLA Air Force to “speed up air and space integration and sharpen their offensive and defensive capabilities” as early as 2014, and military experts have designated “near space” as a crucial link in the integration.

    Searches on CNKI, China’s largest online academic database, show Chinese researchers, both military and civilian, have published more than 1,000 papers and reports on “near space,” many of which focus on the development of “near space flight vehicles.” China has also set up a research center to design and develop high-altitude balloons and stratospheric airships, or dirigibles, under the Chinese Academy of Sciences, a top government think tank.

    One particular area of interest is surveillance. While China already deploys a sprawling satellite network for sophisticated long-range surveillance, Chinese military experts have highlighted the advantages of lighter-than-air vehicles.

    Unlike rotating satellites or traveling aircraft, stratospheric airships and high-altitude balloons “can hover over a fixed location for a long period of time” and are not easily detected by radar, wrote Shi Hong, the executive editor of Shipborne Weapons, a prominent military magazine published by a PLA-linked institute, in an article published in state media in 2022.

    In a 2021 video segment run by state news agency Xinhua, a military expert explains how near-space lighter-than-air vehicles can surveil and take higher resolution photos and videos at a much lower cost compared to satellites.

    In the video, Cheng Wanmin, an expert at the National University of Defense Technology, highlighted the progress by the US, Russia and Israel in developing these vehicles, adding China has also made its own “breakthroughs.”

    An example of advances China has made in this domain is the reported flight of a 100-meter-long (328 feet) unmanned dirigible-like airship known as “Cloud Chaser.” In a 2019 interview with the Southern Metropolis Daily newspaper, Wu Zhe, a professor at Beihang University, said the vehicle had transited across Asia, Africa and North America in an around-the-world flight at 20,000 meters (65, 616 feet) above the Earth.

    Another scientist on the team told the newspaper that compared with satellites, stratospheric airships are better for “long-term observation” and have a range of purposes from disaster warning and environmental research to wireless network construction and aerial reconnaissance.

    Cheng Wanmin, an expert at the National University of Defense Technology, discusses the development of lighter-than-air vehicles in a video segment run by state news agency Xinhua in 2021.

    It’s also clear that China is not alone in seeing new uses for a technology that’s been leveraged for military reconnaissance as far back as the late 18th century, when French forces employed a balloon corps.

    The US has also been bolstering its capacity to use lighter-than-air vehicles. In 2021, the US Department of Defense contracted an American aerospace firm to work on using their stratospheric balloons as a means “to develop a more complete operating picture and apply effects to the battlefield,” according to a statement from the firm, Raven Aerostar, at the time.

    “This isn’t just a China thing. The US, and other nations as well, have been working on and developing high-altitude aerostats, balloons and similar vehicles,” said Brendan Mulvaney, director of the China Aerospace Studies Institute (CASI), a research center serving the US Air Force.

    “They are cheap, provide long-term persistent stare for collection of imagery, communications and other information – including weather,” said Mulvaney, who authored a 2020 paper that detailed China’s interest in using lighter-than-air vehicles for “near-space reconnaissance.”

    China also appears acutely aware of the potential for other countries to use balloons to spy.

    In 2019, a documentary series on China’s border defense forces produced by a state-owned television channel featured an incident where the PLA Air Force spotted and shot down a suspected high-altitude surveillance balloon that “threatened (China’s) air defense safety.”

    The documentary did not provide further detail about the time and location of the incident, but a paper published last April by researchers in a PLA institute noted air-drift balloons were spotted over China in 1997 and 2017.

    Other experts have pointed to the potential use of balloons in data collection that can aid China’s development of hypersonic weapons that transit through near space.

    “Understanding the atmospheric conditions up there is critical to programming the guidance software” for ballistic and hypersonic missiles, according to Hawaii-based analyst Carl Schuster, a former director of operations at the US Pacific Command’s Joint Intelligence Center.

    Chinese state media reports show China has also used balloons to test advanced hypersonic vehicles. In 2019, state broadcaster CCTV’s military channel showed footage of a balloon lifting off for what it described as maiden testing of three miniaturized models of “wide-range aircraft,” which according to Chinese media reports, can fly at a wide range of speeds, up to five times the speed of sound.

    A 2019 report broadcast by state broadcaster CCTV's military channel showed footage of a balloon lifting off for what it described as maiden testing of three miniaturized models of

    US intelligence officials believe the Chinese balloon identified over the US in recent days is part of an extensive, Chinese military-run surveillance program involving a fleet of balloons that has conducted at least two dozen missions over at least five continents in recent years, CNN reported on Tuesday.

    Beijing on Thursday said the assessment was “likely part of the US’ information and public opinion warfare” against China. It has maintained that the device identified over the US is civilian in nature, and linked it to “companies,” though it declined to provide more information on which entity manufactured the balloons.

    Both the self-governing island of Taiwan and Japan have acknowledged past, similar sightings, though it is not clear if they are related to the US incident.

    A US military commander on Monday acknowledged that the US has a “domain awareness gap” that allowed three other suspected Chinese spy balloons to transit the continental US undetected during the previous administration.

    An FBI team is working on understanding more about the equipment reclaimed from the balloon shot down over the sea – including what kind of data it could collect and whether it could transmit that in real time.

    CASI’s Mulvaney said that whether the balloon itself is characterized as “dual use” or “state-owned,” data collected would have gone back to China, which is now receiving another kind of information from the incident.

    “At the end of the day responses and (tactics, techniques, and procedures) from the US and other countries on how they react, or fail to – all of that has value to China and the PLA.”

    What is a suspected Chinese spy balloon doing above the US? | CNN

    [ad_1]


    Seoul, South Korea
    CNN
     — 

    News that the Pentagon is monitoring a suspected Chinese surveillance balloon in the skies over the continental United States raises a series of questions – not least among them, what exactly it might be doing.

    US officials have said the flight path of the balloon, first spotted over Montana on Thursday, could potentially take it over a “number of sensitive sites” and say they are taking steps to “protect against foreign intelligence collection.”

    But what’s less clear is why Chinese spies would want to use a balloon, rather than a satellite to gather information.

    This is not the first time a Chinese balloon has been spotted over the US, but this seems to be acting differently to previous ones, a US defense official said.

    “It is appearing to hang out for a longer period of time, this time around, [and is] more persistent than in previous instances. That would be one distinguishing factor,” the official said.

    Using balloons as spy platforms goes back to the early days of the Cold War. Since then the US has used hundreds of them to monitor its adversaries, said Peter Layton, a fellow at the Griffith Asia Institute in Australia and former Royal Australian Air Force officer.

    But with the advent of modern satellite technology enabling the gathering of overflight intelligence data from space, the use of surveillance balloons had been going out of fashion.

    Or at least until now.

    Recent advances in the miniaturization of electronics mean the floating intelligence platforms may be making a comeback in the modern spying toolkit.

    “Balloon payloads can now weigh less and so the balloons can be smaller, cheaper and easier to launch” than satellites, Layton said.

    Blake Herzinger, an expert in Indo-Pacific defense policy at the American Enterprise Institute, said despite their slow speeds, balloons aren’t always easy to spot.

    “They’re very low signature and low-to-zero emission, so hard to pick up with traditional situational awareness or surveillance technology,” Herzinger said.

    And balloons can do some things that satellites can’t.

    “Space-based systems are just as good but they are more predictable in their orbital dynamics,” Layton said.

    “An advantage of balloons is that they can be steered using onboard computers to take advantage of winds and they can go up and down to a limited degree. This means they can loiter to a limited extent.

    “A satellite can’t loiter and so many are needed to criss-cross an area of interest to maintain surveillance,” he said.

    According to Layton, the suspected Chinese balloon is likely collecting information on US communication systems and radars.

    “Some of these systems use extremely high frequencies that are short range, can be absorbed by the atmosphere and being line-of-sight are very directional. It’s possible a balloon might be a better collection platform for such specific technical collection than a satellite,” he said.

    Retired US Air Force Col. Cedric Leighton, a CNN military analyst, echoed those thoughts.

    “They could be scooping up signals intelligence, in other words, they’re looking at our cell phone traffic, our radio traffic,” Leighton told CNN’s Erin Burnett.

    Intelligence data collected by the balloon could be relayed in real time via a satellite link back to China, Layton said.

    Analysts also noted that Montana and nearby states are home to US intercontinental ballistic missile silos and strategic bomber bases.

    US officials say they have taken actions to ensure the balloon cannot collect any sensitive data. They decided against shooting it down because of the risk to lives and property by falling debris.

    And if the US could bring down the balloon within its territory without destroying it then the balloon might reveal some secrets of its own, Layton added.

    But maybe there are no secrets or spying involved. This could be just an accident, with the balloon blown off course or Chinese operators losing control of it somehow.

    “There’s at least some possibility that this was a mistake and the balloon ended up somewhere Beijing didn’t expect,” Herzinger said.

    For its part, China says it’s looking into things.

    “We are aware of reports [of the balloon] and are trying to understand the circumstances and verify the details of the situation,” a Foreign Ministry spokesperson said Friday. “I’d like to stress that before it becomes clear what happened, any deliberate speculation or hyping up would not help handling of the matter.”

    New York
    CNN Business
     — 

    In the fervor-filled days leading up to the November 16 launch of the long-awaited Artemis I mission, an uncrewed trip around the moon, some industry insiders admitted to having conflicting emotions about the event.

    On one hand, there was the thrill of watching NASA take its first steps toward eventually getting humans back to the lunar surface; on the other, a shadow cast by the long and costly process it took to get there.

    “I have mixed feelings, though I hope that we have a successful mission,” former NASA astronaut Leroy Chiao said in an opinion roundtable interview with The New York Times. “It is always exciting to see a new vehicle fly. For perspective, we went from creating NASA to landing humans on the moon in just under 11 years. This program has, in one version or another, been ongoing since 2004.”

    There have been numerous delays with the development of the rocket at the center of the Artemis I mission: NASA’s Space Launch System (SLS), the most powerful rocket ever flown — and one of the most controversial. The towering launch vehicle was originally expected to take flight in 2016. And the decade-plus that the rocket was in development sparked years of blistering criticism targeted toward the space agency and Boeing, which holds the primary contract for the SLS rocket’s core.

    NASA’s Office of Inspector General (OIG) repeatedly called out what it referred to as Boeing’s “poor performance,” as a contributing factor in the billions of dollars in cost overruns and schedule delays that plagued SLS.

    “Cost increases and schedule delays of Core Stage development can be traced largely to management, technical, and infrastructure issues driven by Boeing’s poor performance,” one 2018 report from NASA’s OIG, the first in a series of audits the OIG completed surrounding NASA’s management of the SLS program, read. And a report in 2020 laid out similar grievances.

    For its part, Boeing has pushed back on the criticism, pointing to rigorous testing requirements and the overall success of the program. The OIG report also included correspondence from NASA, which noted in 2018 that it “had already recognized the opportunity to improve contract performance management” and agreed with the report’s recommendations.

    In various op-eds, the rocket has also been deemed “the result of unfortunate compromises and unholy politics,” a “colossal waste of money” and an “irredeemable mistake.”

    Despite all the heated debate that has followed SLS, by all accounts, the rocket is here to stay. And officials at NASA and Boeing said its first launch two months ago was practically flawless.

    “I worked over 50 Space Shuttle launches,” Boeing SLS program manager John Shannon told CNN by phone. “And I don’t ever remember a launch that was as clean as that one was, which for a first-time rocket — especially one that had been through as much as this one through all the testing — really put an exclamation point on how reliable and robust this vehicle really is.”

    The Artemis program manager at NASA, Mike Sarafin, also said during a post-launch news conference that the rocket “performed spot-on.”

    But with its complicated history and its hefty price tag, SLS could still face detractors in the years to come.

    Many have questioned why SLS needs to exist at all. With the estimated cost per launch standing at more than $4 billion for the first four Artemis missions, it’s possible commercial rockets, like the massive Mars rocket SpaceX is building, could get the job done more efficiently, as the chief of space policy at the nonprofit exploration advocacy group Planetary Society, Casey Dreier, recently observed in an article laying out both sides of the SLS argument.

    (NASA Administrator Bill Nelson noted that the $4 billion per-launch cost estimate includes development costs that the space agency hopes will be amortized over the course of 10 or more missions.)

    Boeing was selected in 2012 to build SLS’s “core stage,” which is the hulking orange fuselage that houses most of the massive engines that give the rocket its first burst of power at liftoff.

    Though more than 1,000 companies were involved with designing and building SLS, Boeing’s work involved the largest and most expensive portion of the rocket.

    That process began over a decade ago, and when the Artemis program was established in 2019, it gave the rocket its purpose: return humans to the moon, establish a permanent lunar outpost, and, eventually, pave the path toward getting humans to Mars.

    But the SLS is no longer the only rocket involved in the program. NASA gave SpaceX a significant role in 2021, giving the company a fixed-price contract for use of its Mars rocket as the vehicle that will ferry astronauts to the lunar surface after they leave Earth and travel to the moon’s orbit on SLS. SpaceX’s forthcoming rocket, called Starship, is also intended to be capable of completing a crewed mission to the moon or Mars on its own. (Starship, it should be noted, is still in the development phases and has not yet been tested in orbit.)

    Boeing has repeatedly argued that SLS is essential and capable of performing tasks that other rockets cannot.

    “The bottom line is there’s nothing else like the SLS because it was built from the ground up to be human rated,” Shannon said. “It is the only vehicle that can take the Orion spacecraft and the service module to the moon. And that’s the purpose-built design — to take large hardware and humans to cislunar space, and nothing else exists that can do that.”

    Starship, meanwhile, is not tailored solely to NASA’s specific lunar goals. SpaceX CEO Elon Musk has talked for more than a decade about his desire to get humans to Mars. More recently, he has said Starship could also be used to house giant space telescopes.

    Yet, another reason critics remain skeptical of SLS is because of its origins. The rocket’s conception can be traced back to NASA’s Constellation program, which was a plan to return to the moon mapped out under former President George W. Bush that was later canceled.

    But the SLS has survived. Many observers have suggested a big reason was the desire to maintain space industry jobs in certain Congressional districts and to beef up aerospace supply chains.

    Members of Congress and NASA Administrator Charles Bolden unveil the Space Launch System design on September 14, 2011. From left: Sen. Kay Bailey Hutchison R-Texas, Sen. John Boozman, R-Ark., Sen. Bill Nelson, D-Fla., Rep. Chaka Fattah, D-Pa., Administrator Bolden.

    Much of the criticism levied against SLS, however, has focused on the actual process of getting the rocket built.

    At one point in 2019, former NASA administrator Jim Bridenstine considered sidelining the SLS rocket entirely, citing frustrations with the delays.

    “At the end of the day, the contractors had an obligation to deliver what NASA had contracted for them to deliver,” Bridenstine told CNN by phone last month. “And I was frustrated like most of America.”

    Still, Bridenstine said, when his office reviewed the matter, it found “there were no options that were going to cost less money or take less time than just finishing the SLS” — and the rocket was never ultimately sidelined. (Bridenstine noted he was also publicly critical of delayed projects led by SpaceX and others.)

    NASA continued to stand by Boeing and the SLS rocket even as it became a political hot potato, with some in Congress both criticizing its costs and refusing to abandon the program.

    The SLS rocket ended up flying its first launch more than six years later than originally intended. NASA had allocated $6.2 billion to the SLS program as of 2018, but that price tag more than tripled to $23 billion as of 2022, according to an analysis by the Planetary Society.

    Those escalating costs can be traced back to the type of contracts that NASA signed with Boeing and its other major suppliers for SLS. It’s called cost-plus, which puts the financial burden on NASA when projects face cost overruns while still offering contractors extra payments, or award fees.

    In testimony before the Senate Appropriations Subcommittee on Science last year, current NASA Administrator Bill Nelson criticized the cost-plus contracting method, calling it a “plague.”

    More in vogue are “fixed-price” contracts, which have a firm price cap, like the kind NASA gave to Boeing and SpaceX for its Commercial Crew Program.

    In an interview with CNN in December, however, Nelson stood by cost-plus contracting for SLS and Orion, the vehicle that is designed to carry astronauts and rides atop the rocket to space. He said that without that type of contract, in his view, NASA’s private-sector contractors simply wouldn’t be willing to take on a rocket designed for such a specific purpose and exploring deep space. Building a rocket as specific and technically complex as SLS isn’t a risk many private-sector companies are anxious to take on, he noted.

    “You really have difficulty in the development of a new and very exquisite spacecraft … on a fixed-price contract,” he said.

    “That industry is just not willing to accept that kind of thing, with the exception of the landers,” he added, referring to two other branches of the Artemis program: robotic landers that will deliver cargo to the moon’s surface and SpaceX’s $2.9 billion lunar lander contract. Both of those will use fixed-price — often referred to as “commercial” — contracts.

    Commercial landers will carry NASA-provided science and technology payloads to the lunar surface, paving the way for NASA astronauts to land on the Moon by 2024.

    “And even there, they’re getting a considerable investment by the federal government,” Nelson said.

    Still, government watchdogs have not pulled punches when assessing these cost-plus contracts and Boeing’s role.

    “We did notice very poor contractor performance on Boeing’s part. There’s poor planning and poor execution,” NASA Inspector General Paul Martin said during testimony before the House’s Subcommittee on Space and Aeronautics last year. “We saw that the cost-plus contracts that NASA had been using…worked to the contractor’s — rather than NASA’s — advantage.”

    Shannon, the Boeing executive, acknowledged in an interview that Boeing and SLS have faced loud detractors, but he said that the value of the drawn out development and testing program would become evident as SLS flies.

    “I am extremely proud that NASA — even though there were significant schedule pressures — they could set up a test program that was incredibly comprehensive,” he said. “The Boeing team worked through that test process and hit every mark on it. And you see the results. You see a vehicle that is not just visually spectacular, but its performance was spectacular. And it really put us on the road to be able to do lunar exploration again, which is something that’s very important in this country.”

    But the rocket is still facing criticism. During a Congressional hearing with the House’s Science, Space, and Technology Committee in March 2022, NASA’s Inspector General said that current cost estimates for SLS were “unsustainable,” gauging that the space agency will have spent $93 billion on the Artemis program from 2012 through September 2025.

    Martin, the NASA inspector general, specifically pointed to Boeing as one of the contractors that would need to find “efficiencies” to bring down those costs as the Artemis program moves forward.

    In a December 7 statement to CNN, Boeing once again defended SLS and its price point.

    “Boeing is and has been committed to improving our processes — both while the program was in its developmental stage and now as it transitions to an operational phase,” the statement read, noting the company already implemented “lessons learned” from building the first rocket to “drive efficiencies from a cost and schedule perspective” for future SLS rockets.

    “When adjusted for inflation, NASA has developed SLS for a quarter of the cost of the Saturn V and half the cost of the Space Shuttle,” the statement noted. “These programs have also been essential to investing in the NASA centers, workforce and test facilities that are used by a broad range of civil and commercial partners across NASA and industry.”

    The successful launch of SLS was a welcome winning moment for Boeing. Over the past few years, the company has been mired in controversy, including ongoing delays and myriad issues with Starliner, a spacecraft built for NASA’s Commercial Crew Program, and scandal after scandal plaguing its airplane division.

    Now that the Artemis I mission has returned safely home, NASA and Boeing can turn to preparing more of the gargantuan SLS rockets to launch even loftier missions.

    SLS is slated to launch the Artemis II mission, which will take four astronauts on a journey around the moon, in 2024. From there, SLS will be the backbone of the Artemis III mission that will return humans to the lunar surface for the first time in five decades and a series of increasingly complex missions as NASA works to create its permanent lunar outpost.

    Shannon, the Boeing SLS program manager, told CNN that construction of the next two SLS rocket cores is well underway, with the booster for Artemis II on track to be finished in April — more than a year before the mission is scheduled to take off. All of the “major components” for a third SLS rocket are also completed, Shannon added.

    For the third SLS core and beyond, Boeing is also moving final assembly to new facilities Florida, freeing up space at its manufacturing facilities to increase production, which may help drive down costs.

    Shannon declined to share a specific price point for the new rockets or share any internal pricing goals, though NASA is expected to sign new contracts for the rockets that will launch the Artemis V mission and beyond, which could significantly change the price per launch.

    Nelson also told CNN in December that NASA “will be making improvements, and we will find cost savings where we can,” such as with the decision to use commercial contracts for other vehicles under the Artemis program umbrella.

    How and whether those contracts bear out remain to be seen: SpaceX needs to get its Starship rocket flying, a massive space station called Gateway needs to come to fruition, and at least some of the robotic lunar landers designed to carry cargo to the moon will need to prove their effectiveness. It’s also not yet clear whether those contracts will result in enough cost savings for the critics of SLS, including NASA’s OIG, to consider the Artemis program sustainable.

    As for SLS, Nelson also told reporters December 11, just after the conclusion of the Artemis I mission, that he had every reason to expect that lawmakers would continue to fund the rocket and NASA’s broader moon program.

    “I’m not worried about the support from the Congress,” Nelson said.

    And Bridenstine, Nelson’s predecessor who has been publicly critical SLS, said that he ultimately stands by SLS and points out that, controversies aside, it does have rare bipartisan support from its bankrollers.

    “We are in a spot now where this is going to be successful,” Bridenstine said last month, recalling when he first realized the Artemis program had support from the right and left. “All of America is going to be proud of this program. And yes, there are going to be differences. People are gonna say well, you should go all commercial and drop SLS…but at the end of the day, what we have to do is we have to bring together all of the things that are the best programs that we can get for America and use them to go to the moon.”
