     — 

    A planned spacewalk by the Russian space agency Roscosmos has been called off following the discovery of a coolant leak coming from the Soyuz MS-22 spacecraft, which is currently docked to the International Space Station.

    NASA’s Rob Navias, speaking on the NASA TV broadcast, called it a “fairly significant” leak. Live images during the broadcast showed liquid spewing out from the Soyuz. Navias said the leak was first observed around 7:45 p.m. ET Wednesday.

    The Soyuz spacecraft is docked to the Russian segment of the space station.

    The crew is safe, and all systems of the space station and the ship are operating normally, according to Roscosmos, in a statement in Russian released Thursday morning on Twitter. (CNN translated the statement.)

    “The crew reported that the warning device of the ship’s diagnostic system went off, indicating a pressure drop in the cooling system,” according to Roscosmos. “A visual inspection confirmed the leak, after which it was decided to interrupt the planned extravehicular activities by the crew members of the ISS Russian Segment Sergey Prokopiev and Dmitry Petelin.”

    Navias said the cause of the coolant leak is “unknown and the effect at this point unknown as Russian managers continue to look over the data and consult with both NASA managers and engineers” and outside experts. He said the astronauts inside the space station were “never in any danger.”

    Russian cosmonaut Anna Kikina, using the camera on Russia’s Nauka module on the space station, “photographed and filmed the outer surface of the ship,” according to Roscosmos. “The data was transmitted to Earth, and the specialists have already begun to study the images.”

    “No decisions have been made regarding the integrity of the Soyuz MS-22 or what the next course of action will be,” Navias added, wrapping up NASA-TV coverage of the canceled spacewalk.

    Roscosmos added that the situation will be analyzed before a decision is made about what comes next.

    NASA took a similar tone in a Thursday statement: “NASA and Roscosmos will continue to work together to determine the next course of action following the ongoing analysis.”

    The Soyuz MS-22 ferried NASA astronaut Frank Rubio and two Russian cosmonauts to the space station on September 21 and is scheduled to bring them back to Earth in late March.

    Japanese lunar exploration company ispace began its long-anticipated first mission on Sunday, with a SpaceX Falcon 9 rocket launching the venture’s lunar lander from Florida.

    “This is the very, very beginning of a new era,” ispace founder and CEO Takeshi Hakamada told CNBC.

    The Tokyo-based company’s Mission 1 is currently on its way to the moon, with a landing expected near the end of April.

    Founded more than a decade ago, ispace originated as a team competing for the Google Lunar Xprize under the name Hakuto – after a mythological Japanese white rabbit. After the Xprize competition was canceled, ispace pivoted and expanded its goals, with Hakamada aiming to create “an economically viable ecosystem” around the moon, he said in a recent interview.

    The company has grown steadily as it worked toward this first mission, with over 200 employees around the world – including about 50 at its U.S. subsidiary in Denver. Additionally, ispace has steadily raised funds from a wide variety of investors, bringing in $237 million to date through a mixture of equity and debt. The investors of ispace include the Development Bank of Japan, Suzuki Motor, Japan Airlines, and Airbus Ventures.

    The ispace Mission 1 lander carries small rovers and payloads for a number of government agencies and companies – including from the U.S., Canada, Japan, and the United Arab Emirates.

    Before the launch, ispace outlined 10 milestones for the mission – with the company having completed the first three so far: Preparation for launch, deployment after launch, and then establishing a communication link. Next up is to maneuver in orbit, and then a one-month period flying through space before entering the moon’s orbit. The milestones demonstrate the complexity and difficulty of ispace’s mission, with Hakamada emphasizing both his confidence in the mission, as well as noting that each milestone represents another step forward for the company’s goals.

    “I have 100% trust in our engineering team, they have been doing the right things to accomplish our successful landing on the lunar surface,” Hakamada said.

    If successful, ispace would be the first private company to land on the moon – a feat previously accomplished by global superpowers.

  • Historic moon mission ends with splashdown of Orion capsule | CNN

    Historic moon mission ends with splashdown of Orion capsule | CNN

     — 

    The Artemis I mission — a 25½-day uncrewed test flight around the moon meant to pave the way for future astronaut missions — came to a momentous end as NASA’s Orion spacecraft made a successful ocean splashdown Sunday.

    The spacecraft finished the final stretch of its journey, closing in on the thick inner layer of Earth’s atmosphere after traversing 239,000 miles (385,000 kilometers) between the moon and Earth. It splashed down at 12:40 p.m. ET Sunday in the Pacific Ocean off Mexico’s Baja California.

    This final step was among the most important and dangerous legs of the mission.

    But after splashing down, Rob Navias, the NASA commentator who led Sunday’s broadcast, called the reentry process “textbook.”

    “I’m overwhelmed,” NASA Administrator Bill Nelson said Sunday. “This is an extraordinary day.”

    The capsule is now bobbing in the Pacific Ocean, where it will remain until nearly 3 p.m. ET as NASA collects additional data and runs through some tests. That process, much like the rest of the mission, aims to ensure the Orion spacecraft is ready to fly astronauts.

    “We’re testing all of the heat that has come and been generated on the capsule. We want to make sure that we characterize how that’s going to affect the interior of the capsule,” NASA flight director Judd Frieling told reporters last week.

    A fleet of recovery vehicles — including boats, a helicopter and a US Naval ship called the USS Portland — are waiting nearby.

    The spacecraft was traveling about 32 times the speed of sound (24,850 miles per hour or nearly 40,000 kilometers per hour) as it hit the air — so fast that compression waves caused the outside of the vehicle to heat to about 5,000 degrees Fahrenheit (2,760 degrees Celsius).

    “The next big test is the heat shield,” Nelson had told CNN in a phone interview Thursday, referring to the barrier designed to protect the Orion capsule from the excruciating physics of reentering the Earth’s atmosphere.

    The extreme heat also caused air molecules to ionize, creating a buildup of plasma that caused a 5½-minute communications blackout, according to Artemis I flight director Judd Frieling.

    INTERACTIVE: Trace the path Artemis I will take around the moon and back

    As the capsule reached around 200,000 feet (61,000 meters) above the Earth’s surface, it performed a roll maneuver that briefly sent the capsule back upward — sort of like skipping a rock across the surface of a lake.

    There are a couple of reasons for using the skip maneuver.

    “Skip entry gives us a consistent landing site that supports astronaut safety because it allows teams on the ground to better and faster coordinate recovery efforts,” said Joe Bomba, Lockheed Martin’s Orion aerosciences aerothermal lead, in a statement. Lockheed is NASA’s primary contractor for the Orion spacecraft.

    “By dividing the heat and force of reentry into two events, skip entry also offers benefits like lessening the g-forces astronauts are subject to,” according to Lockheed, referring to the crushing forces humans experience during spaceflight.

    Another communications blackout lasting about three minutes followed the skip maneuver.

    As it embarked on its final descent, the capsule slowed down drastically, shedding thousands of miles per hour in speed until its parachutes deploy. By the time it splashed down, Orion was traveling about 20 miles per hour (32 kilometers per hour).

    While there were no astronauts on this test mission — just a few mannequins equipped to gather data and a Snoopy doll — Nelson, the NASA chief, has stressed the importance of demonstrating that the capsule can make a safe return.

    The space agency’s plans are to parlay the Artemis moon missions into a program that will send astronauts to Mars, a journey that will have a much faster and more daring reentry process.

    The Orion capsule captures a view of the lunar surface, with Earth in the background lit in the shape of a crescent by the sun.

    Orion traveled roughly 1.3 million miles (2 million kilometers) during this mission on a path that swung out to a distant lunar orbit, carrying the capsule farther than any spacecraft designed to carry humans has ever traveled.

    A secondary goal of this mission was for Orion’s service module, a cylindrical attachment at the bottom of the spacecraft, to deploy 10 small satellites. But at least four of those satellites failed after being jettisoned into orbit, including a miniature lunar lander developed in Japan and one of NASA’s own payload that was intended to be one of the first tiny satellites to explore interplanetary space.

    On its trip, the spacecraft captured stunning pictures of Earth and, during two close flybys, images of the lunar surface and a mesmerizing “Earth rise.”

    Nelson said if he had to give the Artemis I mission a letter grade so far, it would be an A.

    “Not an A-plus, simply because we expect things to go wrong. And the good news is that when they do go wrong, NASA knows how to fix them,” Nelson said. But “if I’m a schoolteacher, I would give it an A-plus.”

    With the success of the Artemis I mission, NASA will now dive into the data collected on this flight and look to choose a crew for the Artemis II mission, which could take off in 2024.

    Artemis II will aim to send astronauts on a similar trajectory as Artemis I, flying around the moon but not landing on its surface.

    The Artemis III mission, currently slated for a 2025 launch, is expected to put boots back on the moon, and NASA officials have said it will include the first woman and first person of color to achieve such a milestone.

  • NASA capsule flies over Apollo landing sites, heads home

    NASA capsule flies over Apollo landing sites, heads home

    [ad_1]

    CAPE CANAVERAL, Fla. — NASA’s Orion capsule and its test dummies swooped one last time around the moon Monday, flying over a couple Apollo landing sites before heading home.

    Orion will aim for a Pacific splashdown Sunday off San Diego, setting the stage for astronauts on the next flight in a couple years.

    The capsule passed within 80 miles (130 kilometers) of the far side of the moon, using the lunar gravity as a slingshot for the 237,000-mile (380,000-kilometer) ride back to Earth. It spent a week in a wide, sweeping lunar orbit.

    Once emerging from behind the moon and regaining communication with flight controllers in Houston, Orion beamed back photos of a close-up moon and a crescent Earth — Earthrise — in the distance.

    “Orion now has its sights set on home,” said Mission Control commentator Sandra Jones.

    The capsule also passed over the landing sites of Apollo 12 and 14. But at 1,200 miles (1,900 kilometers) up, it was too high to make out the descent stages of the lunar landers or anything else left behind by astronauts more than a half-century ago. During a similar flyover two weeks ago, it was too dark for pictures. This time, it was daylight.

    Deputy chief flight director Zebulon Scoville said nearby craters and other geologic features would be visible in any pictures, but little else.

    “It will be more of a tip of the hat and a historical nod to the past,” Scoville told reporters last week.

    The three-week test flight has exceeded expectations so far, according to officials. But the biggest challenge still lies ahead: hitting the atmosphere at more than 30 times the speed of sound and surviving the fiery reentry.

    Orion blasted off Nov. 16 on the debut flight of NASA’s most powerful rocket ever, the Space Launch System or SLS.

    The next flight — as early as 2024 — will attempt to carry four astronauts around the moon. The third mission, targeted for 2025, will feature the first lunar landing by astronauts since the Apollo moon program ended 50 years ago this month.

    Apollo 17 rocketed away Dec. 7, 1972, from NASA’s Kennedy Space Center, carrying Eugene Cernan, Harrison Schmitt and Ron Evans. Cernan and Schmitt spent three days on the lunar surface, the longest stay of the Apollo era, while Evans orbited the moon. Only Schmitt is still alive.

    ———

    This story has been updated to show that NASA now estimates the flyover of Apollo sites was 1,200 miles above the moon, not 6,000 miles.

  • 3 Chinese astronauts return to Earth after 6-month mission

    3 Chinese astronauts return to Earth after 6-month mission

    [ad_1]

    BEIJING — Three Chinese astronauts landed in a northern desert on Sunday after six months working to complete construction of the Tiangong station, a symbol of the country’s ambitious space program, state TV reported.

    A capsule carrying commander Chen Dong and astronauts Liu Yang and Cai Xuzhe touched down at a landing site in the Gobi Desert in northern China at approximately 8:10 p.m. (1210 GMT), China Central Television reported.

    Prior to departure, they overlapped for almost five days with three colleagues who arrived Wednesday on the Shenzhou-15 mission for their own six-month stay, marking the first time China had six astronauts in space at the same time. The station’s third and final module docked with the station this month.

    The astronauts were carried out of the capsule by medical workers about 40 minutes after touchdown. They were all smiles, and appeared to be in good condition, waving happily at workers at the landing site.

    “I am very fortunate to have witnessed the completion of the basic structure of the Chinese space station after six busy and fulfilling months in space,” said Chen, who was the first to exit the capsule. “Like meteors, we returned to the embrace of the motherland.”

    Liu, another of the astronauts, said that she was moved to see relatives and her fellow compatriots.

    The three astronauts were part of the Shenzhou-14 mission, which launched in June. After their arrival at Tiangong, Chen, Liu and Cai oversaw five rendezvous and dockings with various spacecraft including one carrying the third of the station’s three modules.

    They also performed three spacewalks, beamed down a live science lecture from the station, and conducted a range of experiments.

    The Tiangong is part of official Chinese plans for a permanent human presence in orbit.

    China built its own station after it was excluded from the International Space Station, largely due to U.S. objections over the Chinese space programs’ close ties to the People’s Liberation Army, the military wing of the ruling Communist Party.

    With the arrival of the Shenzhou-15 mission, the station expanded to its maximum weight of 100 tons.

    Without attached spacecraft, the Chinese station weighs about 66 tons — a fraction of the International Space Station, which launched its first module in 1998 and weighs around 465 tons.

    With a lifespan of 10 to 15 years, Tiangong could one day be the only space station still up and running if the International Space Station retires by around the end of the decade as expected.

    China in 2003 became the third government to send an astronaut into orbit on its own after the former Soviet Union and the United States.

    China has also chalked up uncrewed mission successes: Its Yutu 2 rover was the first to explore the little-known far side of the moon. Its Chang’e 5 probe also returned lunar rocks to Earth in December 2020 for the first time since the 1970s, and another Chinese rover is searching for evidence of life on Mars.

    Officials are reported to be considering an eventual crewed mission to the moon, although no timeline has been offered.

     — 

    The International Space Station will receive a power boost during a spacewalk on Saturday, as NASA astronauts Josh Cassada and Frank Rubio install a solar array outside the floating laboratory.

    The spacewalk is on track to begin at 7:25 a.m. ET and will last for about seven hours, with live coverage streaming on NASA’s website.

    During the event, Cassada will serve as extravehicular crew member 1 and will wear a suit with red stripes, while Rubio will wear an unmarked white suit as extravehicular crew member 2. The duo conducted their first spacewalk together in November. Against the backdrop of spectacular views of Earth, the team assembled a mounting bracket on the starboard side of the space station’s truss.

    This hardware allows for the installation of more rollout solar arrays, called iROSAs, to increase electrical power on the space station.

    The first two rollout solar arrays were installed outside the station in June 2021. The plan is to add a total of six iROSAs, which will likely boost the space station’s power generation by more than 30% once all are operational.

    Two more arrays were delivered to the space station on November 27 aboard the 26th SpaceX Dragon commercial resupply mission, which also carried dwarf tomato seeds and other experiments to the orbiting laboratory.

    The arrays were rolled up like carpet and are 750 pounds (340 kilograms) and 10 feet (3 meters) wide.

    During Saturday’s spacewalk, Cassada and Rubio will install a solar array to increase capacity in one of the space station’s eight power channels, located on the station’s starboard truss.

    Once the array is unfurled and bolted into place by the astronauts, it will be about 63 feet (19 meters) long and 20 feet (6 meters) wide.

    The spacewalking duo will also disconnect a cable to reactivate another power channel that recently experienced “unexpected tripping” on November 26.

    “By isolating a section of the impacted array, which was one of several damaged strings, the goal is to restore 75% of the array’s functionality,” according to a release from NASA.

    Cassada and Rubio will go on another spacewalk on December 19 to install a second roll-out solar array on another power channel, located on the station’s port truss.

    The original solar arrays on the space station are still functioning, but they have been supplying power there for more than 20 years and are showing some signs of wear after long-term exposure to the space environment. The arrays were originally designed to last 15 years.

    Erosion can be caused by thruster plumes, which come from both the station’s thrusters and the crew and cargo vehicles that come and go from the station, as well as micrometeorite debris.

    The new solar arrays are being placed in front of the original ones. It’s a good test for the new solar arrays, because this same design will power parts of the planned Gateway lunar outpost, which will help humans return to the moon through NASA’s Artemis program.

    The new arrays will have a similar 15-year life expectancy. However, since the degradation on the original arrays was expected to be worse, the team will monitor the new arrays to test their true longevity, because they may last longer.

     — 

    Three astronauts lifted off to China’s nearly completed space station on Tuesday, marking the beginning of the country’s long-term presence in space.

    It’s a major achievement for China’s ambitious space program, which has explored the far side of the moon and Mars. The milestone also means the aging International Space Station’s role as the sole venue for continuous human occupancy in Earth’s orbit is coming to an end.

    The three astronauts launched aboard the Shenzhou-15 spacecraft at 11:08 p.m. local time (10:08 a.m. ET) on Tuesday from the Jiuquan Satellite Launch Center in the Gobi Desert, Inner Mongolia. The Shenzhou-15 spacecraft is expected to dock with the Tiangong Space Station about 6.5 hours after launch.

    The arrival of the three astronauts — Fei Junlong, Deng Qingming and Zhang Lu — will mark the first crew rotation on the space station, with two teams overlapping for five to 10 days before the Shenzhou-14 crew, who landed at the station in June, returns to Earth.

    The Shenzhou-15 mission will finish the orbital outpost’s construction, expected by the end of December, and launch the first stage of “its application and development,” Ji Qiming, assistant to the China Manned Space Agency director, said at a press conference on Monday, according to state media Xinhua.

    During the mission, according to state media, the crew will also conduct more than 40 experiments and tests in the fields of space science research, space medicine and space technology, as well as three to four extravehicular activities — performed by astronauts in space suits.

    Once construction is completed, the space station is expected to last for 15 years. China plans to launch two crewed missions and two cargo missions to the station every year, according to the CMSA.

    Tiangong, which means heavenly palace, is smaller than the International Space Station but similar in its modular design. The new space station will typically house three rather than six astronauts.

    Officials at NASA have said it will retire the ISS, which is a collaboration between the US, Russia, Japan, Canada and the European Space Agency, in 2030.

    However, Russia has threatened to quit the ISS starting in 2024, which would make operating the ISS difficult, said Dr. Stefania Paladini, a reader in economics and global security at Birmingham City University in the United Kingdom.

    “There is no clarity about the future of the ISS after 2024. While the US seems committed to extend its life until 2030, Russia threatened to withdraw its participation after that date, (which would) make it extremely challenging to continue flying the ISS,” said Paladini, author of “The New Frontiers of Space: Economic Implications, Security Issues and Evolving Scenarios.”

    “The Chinese Space Station may … end up remaining the only human presence in Earth’s orbit for a while.”

    The new space station is expected to host around 1,000 scientific experiments during its life span.

    Most of the experiments taking place on board the Tiangong will involve research originating from China, but the country has invited experiments from international researchers, including how cancer tumors react to zero gravity.

    China’s astronauts have long been excluded from the ISS, due to US political objections and legislative restrictions. However, CMSA astronauts have trained with their counterparts at the European Space Agency.

    It’s not clear whether China would welcome astronauts from other countries to its space station, but Molly Silk, a doctoral researcher at the University of Manchester in the UK focused on China’s space program, said she thought it very likely that international astronauts would visit in the coming years.

    “Several European astronauts have been learning Chinese in order to better cooperate with their Chinese counterparts, which suggests that a visit to the CSS could be on the cards. Pakistan has also been trying to coordinate with China to send their first astronaut to space,” she said.

    “This project demonstrates to the world that China has both the vision and capabilities to pull off such an immensely challenging feat. The CSS will not only allow for China and other nations to conduct experiments in space, but acts as an important checkpoint for China’s planned international research base on the moon.”

    Earlier this year, the space station’s two laboratory modules — Wentian and Mengtian — docked along the Tianhe core cabin, the main living space for the astronauts.

    The Mengtian lab was launched by China’s massive Long March 5B rocket, remnants of which made an uncontrolled reentry into Earth’s atmosphere in early November.

    It was the fourth uncontrolled reentry for a Long March 5B rocket since China’s space agency started flying it two years ago, as the vehicle was designed without the necessary equipment to steer itself to a safe landing.

    Officials at NASA have slammed China for taking unnecessary risks. However, Tuesday’s launch involved China’s smaller Long March-2F rocket, used for human space flight, which experts have previously said is less likely to produce hazardous debris.

  • Amazon used AWS on a satellite in orbit to speed up data analysis in ‘first-of-its kind’ experiment

    Amazon used AWS on a satellite in orbit to speed up data analysis in ‘first-of-its kind’ experiment

    [ad_1]

    An image captured by the ION Elysian Eleonara satellite in January 2022.

    D-Orbit

    Amazon’s cloud computing division successfully ran a software suite on a satellite in orbit, in a “first-of-its-kind” experiment, the company announced Tuesday.

    AWS, or Amazon Web Services, conducted the prototype satellite software demonstration through partnerships with Italian company D-Orbit and Swedish venture Unibap. The experiment was conducted over the past 10 months in low Earth orbit, using a D-Orbit satellite as the test platform.

    The success of the AWS demo has implications across the space industry, as spacecraft – meaning anything from space stations to satellites – face a bottleneck in both data storage and communications while in orbit.

    A “downlink,” the process of transferring data from orbit, requires a spacecraft connect to a ground station, with limitations such as the speed of the connection, or the time window in which the spacecraft is above the ground station.

    AWS’ software automatically reviewed images to decide which were the most useful to send to the ground. It also reduced the size of images by up to 42%.

    “We demonstrated the capability to increase the [satellite’s] productivity,” AWS vice president Max Peterson told CNBC.

    Sign up here to receive weekly editions of CNBC’s Investing in Space newsletter.

    Peterson added that the experiment also showed that AWS can help companies perform “insight operations on the satellite, instead of having to wait until you can downlink back to Earth.”

    “We can train models to recognize practically anything … [giving] the ability to both improve the utilization of a really expensive asset in space, and be able to take huge amounts of data and get insights and translate it into action faster,” Peterson said.

    AWS has steadily built out its Aerospace and Satellite Solutions unit since its establishment in 2020, with the company providing cloud services to a variety of customers and partners across the space sector.

  • China prepares to send new 3-person crew to space station

    China prepares to send new 3-person crew to space station

    [ad_1]

    BEIJING — Final preparations were being made Monday to send a new three-person crew to China‘s space station as it nears completion amid intensifying competition with the United States.

    The China Manned Space Agency said the Shenzhou-15 mission will take off from the Jiuquan Satellite Launch Center on the edge of the Gobi Desert at 11:08 p.m. Tuesday night.

    The six-month mission, commanded by Fei Junlong and crewed by Deng Qingming and Zhang Lu, will be the last “in the construction phase of China’s space station,” agency official Ji Qiming told reporters Monday.

    Fei, 57, is a veteran of the 2005 four-day Shenzhou-6 mission which was the second in which China sent a human into space. Deng and Zhang are flying in space for the first time.

    The station’s third and final module docked with the station earlier this month, one of the last steps in a more than decade-long effort to maintain a constant crewed presence in orbit.

    The astronauts will overlap briefly onboard the station, named Tiangong, with the previous crew, who arrived in early June for a six-month stay.

    Tiangong has room to accommodate six astronauts at a time. Previous missions to the space station have taken about 13 hours from liftoff to docking.

    Next year, China plans to launch the Xuntian space telescope, which, while not part of Tiangong, will orbit in sequence with the station and can dock occasionally with it for maintenance.

    No other future additions to the space station have been publicly announced.

    The permanent Chinese station will weigh about 66 tons — a fraction of the International Space Station, which launched its first module in 1998 and weighs around 465 tons.

    With a lifespan of 10 to 15 years, Tiangong could one day find itself the only space station still running if the International Space Station adheres to its 30-year operating plan.

    China’s crewed space program is officially three decades old this year, but it truly got underway in 2003, when China became only the third country after the U.S. and Russia to put a human into space using its own resources.

    The program is run by the ruling Communist Party’s military wing, the People’s Liberation Army, and has proceeded methodically and almost entirely without outside support. The U.S. excluded China from the International Space Station because of its program’s military ties.

    China has also chalked up successes with uncrewed missions, and its lunar exploration program generated media buzz last year when its Yutu 2 rover sent back pictures of what was described by some as a “mystery hut” but was most likely only a rock. The rover is the first to be placed on the little-explored far side of the moon.

    China’s Chang’e 5 probe returned lunar rocks to Earth for the first time since the 1970s in December 2000 and another Chinese rover is searching for evidence of life on Mars. Officials are also considering a crewed mission to the moon.

    No timeline has been offered for a crewed lunar mission, even as NASA presses ahead with its Artemis lunar exploration program that aims to send four astronauts around the moon in 2024 and land humans there as early as 2025.

    China’s space program has also drawn controversy. Beijing brushed off complaints that it has allowed rocket stages to fall to Earth uncontrolled after NASA accused it of “failing to meet responsible standards regarding their space debris” when parts of a Chinese rocket landed in the Indian Ocean.

    China’s increasing space capabilities also feature in the latest Pentagon defense strategy.

    “In addition to expanding its conventional forces, the PLA is rapidly advancing and integrating its space, counterspace, cyber, electronic, and informational warfare capabilities to support its holistic approach to joint warfare,” the strategy said.

    The U.S. and China are at odds on a range of issues, especially self-governing Taiwan, which Beijing threatens to annex with force. China responded to a September visit to Taiwan by U.S. House Speaker Nancy Pelosi by firing missiles over the island, holding wargames in surrounding waters and staging a simulated blockade, something that could trigger an American military response.

    CAPE CANAVERAL, Fla. — NASA’s Orion capsule entered an orbit stretching tens of thousands of miles around the moon Friday, as it neared the halfway mark of its test flight.

    The capsule and its three test dummies entered lunar orbit more than a week after launching on the $4 billion demo that’s meant to pave the way for astronauts. It will remain in this broad but stable orbit for nearly a week, completing just half a lap before heading home.

    As of Friday’s engine firing, the capsule was 238,000 miles (380,000 kilometers) from Earth. It’s expected to reach a maximum distance of almost 270,000 miles (432,000 kilometers) in a few days. That will set a new distance record for a capsule designed to carry people one day.

    “It is a statistic, but it’s symbolic for what it represents,” Jim Geffre, an Orion manager, said in a NASA interview earlier in the week. “It’s about challenging ourselves to go farther, stay longer and push beyond the limits of what we’ve previously explored.”

    NASA considers this a dress rehearsal for the next moon flyby in 2024, with astronauts. A lunar landing by astronauts could follow as soon as 2025. Astronauts last visited the moon 50 years ago during Apollo 17.

    Earlier in the week, Mission Control in Houston lost contact with the capsule for nearly an hour. At the time, controllers were adjusting the communication link between Orion and the Deep Space Network. Officials said the spacecraft remained healthy.

    CNN
     — 

    NASA released a selfie taken by the Orion capsule and close-up photos of the moon’s crater-marked landscape as the spacecraft continues on the Artemis 1 mission, a 25-and-a-half day journey that will take it more than 40,000 miles beyond the far side of the moon.

    Orion’s latest selfie — taken Wednesday, the eighth day of the mission, by a camera on one of the capsule’s solar arrays — reveals the spacecraft giving angles with a bit of moon visible in the background. The close-up photos were taken Monday as Orion made its closest approach to the moon, passing about 80 miles (129 kilometers) above the lunar surface.

    Should Orion complete its trek beyond the moon and back to Earth, it will be the furthest a spacecraft intended to carry humans has ever traveled. For now, the capsule is only carrying inanimate, scientific payloads.

    Orion is part of NASA’s Artemis program, which aims to eventually establish a lunar outpost that can permanently host astronauts for the first time in history, in the hopes of one day paving a route to Mars.

    The Artemis I mission launched November 16, when NASA’s beleaguered and long-delayed Space Launch System, or SLS, rocket vaulted the Orion capsule to space, cementing the rocket as the most powerful operational launch vehicle ever built.

    As of Thursday afternoon, the capsule was 222,993 miles (358,972 kilometers) from Earth and 55,819 miles (89,831 kilometers) from the Moon, zipping along at just over 2,600 miles per hour, according to NASA.

    Orion is now about a day from entering a “distant retrograde orbit” around our closest neighbor — distant, because it will be at a very high altitude above the lunar surface, and retrograde, because it will circle the moon in the opposite direction from which the moon travels around Earth.

    The path is meant to “stress test” the Orion capsule, as Michael Sarafin, NASA’s Artemis mission manager, put it last week.

    According to NASA’s Artemis blog, the agency’s television coverage of the distant retrograde orbit insertion burn is scheduled for 4:30 p.m. ET Friday and the burn is scheduled to take place at 4:52 p.m. ET.

    After lapping the moon, the Orion capsule is expected to turn back toward Earth and make a gentle splashdown landing in the Pacific Ocean on December 11.

    Europe seeks bigger piece of space market with new launchers

    [ad_1]

    PARIS — France, Germany and Italy announced an agreement Tuesday for a new-generation European space launcher project as part of apparent efforts to better compete with Elon Musk’s SpaceX and other rocket programs in the U.S. and China.

    A statement from the three governments announced an unspecified amount of public funding for the plan, saying it would be based on market prices and economic conditions for each element of the project. The European Space Agency would award contracts to the companies involved.

    The next-generation Ariane and Vega launchers will be used to boost Europe’s role in the commercial and government satellite markets, the French Finance Ministry said.

    The governments also agreed to support development of European-made mini and micro rocket launch systems.

    European government ministers are meeting with ESA in Paris this week. The agency is scheduled to announce its first new team of astronauts in more than a decade on Wednesday, with a focus on more diversity and what are expected to be the first disabled astronauts.

  • NASA capsule buzzes moon, last big step before lunar orbit

    NASA capsule buzzes moon, last big step before lunar orbit

    [ad_1]

    CAPE CANAVERAL, Fla. — NASA’s Orion capsule reached the moon Monday, whipping around the far side and buzzing the lunar surface on its way to a record-breaking orbit with test dummies sitting in for astronauts.

    It’s the first time a capsule has visited the moon since NASA’s Apollo program 50 years ago, and represents a huge milestone in the $4.1 billion test flight that began last Wednesday.

    Video of the looming moon and our pale blue planet more than 230,000 miles (370,000 kilometers) in the distance left workers “giddy” at Houston’s Johnson Space Center, home to Mission Control, according to flight director Judd Frieling. Even the flight controllers themselves were “absolutely astounded.”

    “Just smiles across the board,” said Orion program manager Howard Hu.

    The close approach of 81 miles (130 kilometers) occurred as the crew capsule and its three wired-up dummies were on the far side of the moon. Because of a half-hour communication blackout, flight controllers in Houston did not know if the critical engine firing went well until the capsule emerged from behind the moon. The capsule’s cameras sent back a picture of the Earth — a tiny blue dot surrounded by blackness.

    The capsule accelerated well beyond 5,000 mph (8,000 kph) as it regained radio contact, NASA said. Less than an hour later, Orion soared above Tranquility Base, where Neil Armstrong and Buzz Aldrin landed on July 20, 1969. There were no photos of the site because the pass was in darkness, but managers promised to try for pictures on the return flyby in two weeks.

    Orion needed to slingshot around the moon to pick up enough speed to enter the sweeping, lopsided lunar orbit. Another engine firing will place the capsule in that orbit Friday.

    This coming weekend, Orion will shatter NASA’s distance record for a spacecraft designed for astronauts — nearly 250,000 miles (400,000 kilometers) from Earth, set by Apollo 13 in 1970. And it will keep going, reaching a maximum distance from Earth next Monday at nearly 270,000 miles (433,000 kilometers).

    The capsule will spend close to a week in lunar orbit, before heading home. A Pacific splashdown is planned for Dec. 11.

    Orion has no lunar lander; a touchdown won’t come until NASA astronauts attempt a lunar landing in 2025 with SpaceX’s Starship. Before then, astronauts will strap into Orion for a ride around the moon as early as 2024.

    Mission manager Mike Sarafin was delighted with the progress of the mission, giving it a “cautiously optimistic A-plus” so far.

    The Space Launch System rocket — the most powerful ever built by NASA — performed exceedingly well in its debut, Sarafin told reporters. He said teams are dealing with two issues that require workarounds — one involving the navigational star trackers, the other the power system,

    The 322-foot (98-meter) rocket caused more damage than expected, however, at the Kennedy Space Center launch pad. The force from the 8.8 million pounds (4 million kilograms) of liftoff thrust was so great that it tore off the blast doors of the elevator, leaving it unusable.

    Sarafin said the pad damage will be repaired in plenty of time before the next launch.

  • Philippines and China tussle over retrieving rocket debris floating in disputed South China Sea | CNN

    Philippines and China tussle over retrieving rocket debris floating in disputed South China Sea | CNN

    [ad_1]


    Hong Kong
    CNN
     — 

    The Philippines and China tussled on Sunday over Chinese rocket debris in the disputed South China Sea, raising tensions ahead of a scheduled visit by US Vice President Kamala Harris.

    A Chinese vessel allegedly blocked a Philippine naval boat twice before taking the debris it was towing off Thitu Island, which is occupied by the Philippines and known locally as Pag-asa Island, said Philippine Vice Admiral Alberto Carlos.

    In a statement issued Monday, Carlos said that the Chinese coast guard had “forcefully retrieved” floating debris off the waters. He said local personnel used a long-range camera and spotted the debris about 800 yards away from a sandbar on Sunday and set out to inspect it.

    The debris was described as “metallic” and similar to fragments recovered in other parts of the country two weeks ago, raising suspicions that it originated from a recent Chinese rocket launch, state-run Philippine News Agency (PNA) reported.

    Speaking at a regular press conference on Monday, Mao Ning, a spokesperson for China’s Ministry of Foreign Affairs, also confirmed that Chinese maritime police ships found an unknown floating object in the disputed waters on Sunday.

    Mao denied any confrontation and told reporters “there was no so-called interception and seizure at the scene.”

    “After identifying it as the debris of a rocket fairing recently launched by China, local personnel first salvaged and towed the floating object. After friendly negotiations between the two sides, the Philippine side returned the floating object to the Chinese side on the spot, and Chinese personnel expressed their gratitude to the Philippine side,” Mao said Monday.

    The incident was reported Sunday, a day before a scheduled visit by Harris to the western province of Palawan where a Philippine military command in charge of defending and patrolling its waters on the edge of the South China Sea is located.

    This was not the first time China’s space debris was found near the Philippines. Debris retrieved in two different locations off the waters of Palawan and Occidental Mindoro may have come from a Long March 5B rocket that China launched in late October, the Philippine Space Agency (PhilSA) said in a statement on November 9.

    “In relation to this, PhilSA would like to reiterate its sustained efforts to promote and encourage accountability among nations for objects launched into space,” the statement said.

    China has been criticized repeatedly for allowing rocket stages to make uncontrolled reentry to Earth, with NASA last year accusing Beijing for “failing to meet responsible standards regarding their space debris” after parts of a Chinese rocket landed in the Indian Ocean.

  • Fired SpaceX employees accuse company of violating labor law

    Fired SpaceX employees accuse company of violating labor law

    [ad_1]

    NEW YORK — Several SpaceX employees who were fired after circulating an open letter calling out CEO Elon Musk’s behavior have filed a complaint accusing the company of violating labor laws.

    The complaint, made Wednesday to the National Labor Relations Board, details the aftermath of what allegedly happened inside SpaceX after employees circulated the letter in June, which, among other things, called on executives to condemn Musk’s public behavior on Twitter — including making light of allegations he sexually harassed a flight attendant — and hold everyone accountable for unacceptable conduct.

    The letter was sent weeks after a media report surfaced that Musk paid $250,000 to the flight attendant to quash a potential sexual harassment lawsuit against him. The billionaire has denied the allegations.

    Employees in their letter urged SpaceX to uniformly enforce its policy against unacceptable behavior and commit to a transparent process for responses to claims of misconduct. A day later, Paige Holland-Thielen and four other employees who participated in organizing the letter were fired, according to the filing, which was made by Holland-Thielen to a regional NLRB office in California. Four additional employees were fired weeks later for their involvement in the letter.

    A company spokesperson did not immediately respond to a request for comment.

    Musk, who is the CEO of Tesla and SpaceX and is currently running Twitter, prefers to do things his own way even if that means running afoul of rules and regulations. He’s currently in a defiant fight with Civil Rights department, a California regulator that is suing Tesla for rampant racial discrimination.

    Some view Musk’s management style as autocratic and demanding, as evidenced by a recent email he sent to Twitter staff giving them until Thursday evening to decide whether they want to remain a part of the business. Musk wrote that employees “will need to be extremely hardcore” to build “a breakthrough Twitter 2.0″ and that long hours at high intensity will be needed for success.

    A number of engineers also said on Twitter they were fired last week after saying something critical of Musk, either publicly on Twitter or on an internal messaging board for Twitter employees.

    In a statement, Holland-Thielen said as a woman engineer at SpaceX, she experienced “deep cultural problems” and comforted colleagues who had experienced similar issues.

    “It was clear that this culture was created from the top level,” she said.

    Still, she said part of what she liked about the company was that any person could escalate issues to leadership and be taken seriously.

    “We drafted the letter to communicate to the executive staff on their terms and show how their lack of action created tangible barriers to the long term success of the mission,” Holland-Thielen said. “We never imagined that SpaceX would fire us for trying to help the company succeed.”

    The firings coincide with Musk’s $44 billion buyout of Twitter. Around the same time, the billionaire used a sexual term to make fun of Microsoft co-founder Bill Gates’ belly and also posted a poop emoji during an online discussion with then-Twitter CEO Parag Agrawal.

    After terminating the first set of employees, SpaceX allegedly interrogated dozens of others over the next two months in private meetings, telling them they couldn’t disclose those conversations to anyone else due to attorney-client privilege, according to the complaint. Four additional employees who helped draft or share the letter were fired in July and August, the filing said, adding up to nine terminations in total.

    “Management used this ‘ends justifies the means’ philosophy to turn a blind eye to the ongoing mistreatment, harassment, and abuse reported by my colleagues, much of which was directly encouraged and inspired by the words and actions of the CEO,” said Tom Moline, who was also fired from SpaceX after organizing the letter.

    Jeffery Pfeffer, a professor who specializes in organizational behavior at Stanford University’s business school, said that the allegations were hardly a surprise given Musk’s leadership style at Twitter. Musk’s success at companies like Tesla and SpaceX have created what he labeled as hubris under the false notion that it was “all about individual genius.”

    “Powerful people get to break the rules. They don’t think they are bound by the same conventions as other people,” Pfeffer said, criticizing Musk’s behavior. He said it showed the arrogance of Musk, one of the world’s richest men: “Why would he think he is a mere mortal?”

  • NASA’s mightiest rocket lifts off 50 years after Apollo

    NASA’s mightiest rocket lifts off 50 years after Apollo

    [ad_1]

    CAPE CANAVERAL, Fla. — NASA’s new moon rocket blasted off on its debut flight with three test dummies aboard Wednesday, bringing the U.S. a big step closer to putting astronauts back on the lunar surface for the first time since the end of the Apollo program 50 years ago.

    If all goes well during the three-week, make-or-break shakedown flight, the crew capsule will be propelled into a wide orbit around the moon and then return to Earth with a Pacific splashdown in December.

    After years of delays and billions in cost overruns, the Space Launch System rocket thundered skyward, rising from Kennedy Space Center on 8.8 million pounds (4 million kilograms) of thrust and hitting 100 mph (160 kph) within seconds. The Orion capsule was perched on top and, less than two hours into the flight, busted out of Earth’s orbit toward the moon.

    “It’s a great day,” said NASA Administrator Bill Nelson.

    The moonshot follows nearly three months of vexing fuel leaks that kept the rocket bouncing between its hangar and the pad. Forced back indoors by Hurricane Ian at the end of September, the rocket stood its ground outside as Nicole swept through last week with gusts of more than 80 mph (130 kph). Although the wind caused some damage, managers gave the green light for the launch.

    An estimated 15,000 people jammed the launch site, with thousands more lining the beaches and roads outside the gates, to witness NASA’s long-awaited sequel to Project Apollo, when 12 astronauts walked on the moon from 1969 and 1972. Crowds also gathered outside NASA centers in Houston and Huntsville, Alabama, to watch the spectacle on giant screens.

    Cheers accompanied the rocket as it rode a huge trail of flames toward space, with a half-moon glowing brightly and buildings shaking as though hit by a major quake.

    “For the Artemis generation, this is for you,” launch director Charlie Blackwell-Thompson called out, referring to all those born after Apollo.

    The liftoff marked the start of NASA’s Artemis lunar-exploration program, named after Apollo’s mythological twin sister. The space agency is aiming to send four astronauts around the moon on the next flight, in 2024, and land humans there as early as 2025.

    “You have earned your place in history,” Blackwell-Thompson told her team following liftoff.

    The 322-foot (98-meter) SLS is the most powerful rocket ever built by NASA, with more thrust than either the space shuttle or the mighty Saturn V that carried men to the moon. A series of hydrogen fuel leaks plagued the summertime launch attempts as well as countdown tests. A fresh leak erupted at a new location during Tuesday night’s fueling, but an emergency team managed to tighten the faulty valve on the pad. Then a U.S. Space Force radar station went down, resulting in another scramble, this time to replace an ethernet switch.

    “The rocket, it’s alive. It’s creaking. It’s making venting noises. It’s pretty scary. … My heart was pumping. My nerves were going,” said Trent Annis, one of the three men who entered the blast danger zone to fix Tuesday night’s leak.

    Orion should reach the moon by Monday, more than 230,000 miles (370,000 kilometers) from Earth. After coming within 80 miles (130 kilometers) of the moon, the capsule will enter a far-flung orbit stretching about 40,000 miles (64,000 kilometers) beyond.

    The $4.1 billion test flight is set to last 25 days, roughly the same as when crews will be aboard. The space agency intends to push the spacecraft to its limits and uncover any problems before astronauts strap in. The mannequins — NASA calls them moonequins — are fitted with sensors to measure such things as vibration, acceleration and cosmic radiation.

    The rocket was supposed to have made its dry run by 2017. Government watchdogs estimate NASA will have spent $93 billion on the project by 2025.

    Ultimately, NASA hopes to establish a base on the moon and send astronauts to Mars by the late 2030s or early 2040s.

    But many hurdles still need to be cleared. The Orion capsule will take astronauts only to lunar orbit, not the surface.

    NASA has hired Elon Musk’s SpaceX to develop Starship, the 21st-century answer to Apollo’s lunar lander. Starship will carry astronauts back and forth between Orion and the lunar surface, at least on the first trip in 2025. The plan is to station Starship and eventually other companies’ landers in orbit around the moon, ready for use whenever new Orion crews pull up.

    Reprising an argument that was made during the 1960s, Duke University historian Alex Roland questions the value of human spaceflight, saying robots and remote-controlled spacecraft could get the job done more cheaply, efficiently and safely.

    “In all these years, no evidence has emerged to justify the investment we have made in human spaceflight — save the prestige involved in this conspicuous consumption,” he said.

    NASA is waiting until this test flight is over before introducing the astronauts who will be on the next one and those who will follow in the bootsteps of Apollo 11′s Neil Armstrong and Buzz Aldrin.

    Most of NASA’s corps of 42 active astronauts and 10 trainees were not even born yet when Apollo 17 moonwalkers Gene Cernan and Harrison Schmitt closed out the era, 50 years ago next month.

    “We are jumping out of our spacesuits with excitement,” astronaut Christina Koch said Tuesday.

    After a nearly yearlong space station mission and all-female spacewalk, Koch, 43, is on NASA’s short list for a lunar flight. So is astronaut Kayla Barron, 35, who finally got to witness her first rocket launch, not counting her own a year ago.

    “It took my breath away, and I was tearing up,” Barron said. “What an amazing accomplishment for this team.”

  • Apple invested $450 million in a satellite-powered SOS system. We tested it out | CNN Business

    Apple invested $450 million in a satellite-powered SOS system. We tested it out | CNN Business

    [ad_1]



    CNN Business
     — 

    When Apple announced at its closely-watched September product launch event that it would soon introduce an Emergency SOS feature powered by a network of satellites orbiting above Earth, Brooklyn probably wasn’t the secluded location most had in mind for using it.

    But on a rainy afternoon last week, I found myself trying to stay connected to one of the satellites from Prospect Park as part of a demo of the upcoming feature. I stepped out from under a giant oak tree and the rain started to come down harder. Then I moved my device slightly to the right and quickly regained access to the signal and continued messaging with an emergency dispatcher.

    The rain wasn’t the issue; it was the foliage limiting my phone’s view of the sky.

    On Tuesday, Apple

    (AAPL)
    will launch the Emergency SOS via Satellite feature for those with an iPhone 14 in the United States and Canada, with plans to roll it out in the UK, France, Germany and Ireland next month. The free feature promises to let iPhone users contact dedicated dispatchers in emergency situations via satellites when a cell phone network is unavailable.

    Hikers, emergency responders and intrepid travelers may be well versed in the existing world of satellite phones, which provide voice, SMS, and data services anywhere on Earth. Now Apple is attempting to do the same with its iPhones, as part of a broader pitch this year to consumers that its devices don’t just help them live better, but also live safer. In the process, it could make its pricey products seem a bit more indispensable in an uncertain economic environment that has some rethinking expenses.

    Apple recently invested $450 million in Globalstar, a global satellite service, and other providers to support the development of 24 low-orbit satellites flying 16,000 mph at a higher altitude than the International Space Station. The investment is part of Apple’s Advanced Manufacturing Fund, which has previously been used for glass production with Corning and laser technology for facial recognition.

    During my test with an iPhone 14 provided by Apple, I attempted to call 911 but was automatically redirected to Emergency SOS via Satellite dispatchers for the purposes of the demo. When the device was unable to connect to cellular service, a small green icon appeared at the bottom right of the call screen to initiate a text conversation with emergency services.

    I was prompted to fill out a questionnaire and tapped through a handful of short multiple choice questions; I noted I was lost but not injured. Nearly 20 seconds later, I received confirmation that my geo-location coordinates were sent to a dispatcher, along with my medical ID, emergency contact information and the answers to my questions. I was told to keep responses short, likely to cut down on the amount of data needed to transfer to the satellite and back down to a dispatcher. I was also asked to identify nearby landmarks and where I entered the park. My total exchange lasted about four minutes.

    Apple said the size of messages was greatly condensed so the satellite can more efficiently route them to ground stations located all over the world. Once received, texts are sent to local emergency services or a relay center with Apple-trained emergency specialists who can send help.

    But even in a city, I lost access to the satellite several times when I wasn’t in clear view of the sky. A grayscale circle with a green signal image showed up when connected but turned yellow when conditions were poor and red when connectivity was lost. I walked about 200 feet away from my original location to find a satellite. Once there, I held the device naturally in my hand; Apple said there’s no need to raise or wave it around.

    When it works, the lifesaving potential for such a feature is obvious. But there are some caveats. To start, it’s text only; users will need to physically have the device in their hands to start an exchange, which may not always be possible if injured. The tool does, however, work with the iPhone 14 and Apple Watch’s crash detection feature, so it could automatically dial emergency services or send coordinates to a dispatcher when a user is unconscious or unable to reach their iPhone.

    For now, Emergency SOS via satellite only works in English, Spanish, and French, although the dispatchers have professional interpretation services available for many more languages. Apple said it also may not work in all areas, such as in places above 62° latitude, including northern parts of Canada and Alaska.

    For iPhone 14 users who want to see how the tool works, and test out the process for searching for a satellite, a demo is now available in Settings under “Emergency SOS via satellite.” Apple said the feature is available for free for two years and then it will reevaluate the offering based on what it’s learned about usage during that time.

    CNN
     — 

    Things are about to get busy on the International Space Station as the first in a series of end-of-the-year spacewalks kicked off Tuesday morning.

    First-time spacewalkers and NASA astronauts Josh Cassada and Frank Rubio began their excursion outside the space station at 9:14 a.m. ET, with live coverage on NASA’s website. The event is expected to last for about seven hours.

    Cassada is wearing the spacesuit with red stripes as extravehicular crew member 1, while Rubio is in the unmarked suit as extravehicular crew member 2.

    The astronauts will assemble a mounting bracket on the starboard side of the space station’s truss. The hardware that will be installed during the spacewalk was delivered to the space station on November 9 aboard a Northrop Grumman’s Cygnus spacecraft, which safely delivered its cargo despite only one of its two solar arrays deploying after launch.

    This hardware will allow for the installation of more rollout solar arrays, called iROSAs, to give the space station a power boost. The first two rollout solar arrays were installed outside the station in June 2021. Six iROSAs total have been planned and will likely boost the space station’s power generation by more than 30% once all are operational.

    During two more spacewalks on November 28 and December 1, a two-astronaut crew will unroll and install another pair of solar arrays once the mounting hardware is in place. The solar arrays will be delivered on the next SpaceX Dragon commercial resupply mission, currently slated for launch on November 21.

    Spacewalks are part of the space station crew’s routine as they maintain and upgrade the aging orbital laboratory, but Tuesday’s spacewalk is NASA’s first since March. The agency’s spacewalks came to a halt after European Space Agency astronaut Matthias Maurer ended his first spacewalk with water in his helmet.

    A thin layer of moisture that exceeded the normal, expected amount was discovered in Maurer’s helmet once he returned to the airlock after a nearly seven-hour spacewalk. Maurer quickly shed the helmet, in an event deemed “a close-call” by NASA, and water samples, suit hardware and the spacesuit itself were returned to Earth for investigation. Officials at NASA determined the suit didn’t experience any hardware failures.

    “The cause for the water in the helmet was likely due to integrated system performance where several variables such as crew exertion and crew cooling settings led to the generation of comparatively larger than normal amounts of condensation within the system,” according to NASA in a blog post update.

    “Based on the findings, the team has updated operational procedures and developed new mitigation hardware to minimize scenarios where integrated performance results in water accumulation, while absorbing any water that does appear. These measures will help contain any liquid in the helmet to continue to keep crew safe.”

    Officials at NASA gave the “go” for spacewalks to resume after concluding the review in October.

    The investigation team has developed techniques to manage temperatures in the suit and added new absorption bands to the helmet, said Dina Contella, operations integration manager for the International Space Station Program.

    The thin orange pieces have been placed in different parts of the helmet, which has already been tested on orbit by the astronauts inside the space station.

    “We’ve taken several different models of this up and the crew on board sloshed water around, essentially tried to inject water into the helmet at the same rate that would be kind of a worst, worst case. And we found that these pads were very, very effective,” Contella said.

    Tuesday’s spacewalk will allow the crew to test the new pads as they work outside of the space station before the more complex solar array installation spacewalks within the next couple of weeks.

    Meanwhile, a Russian spacewalk is scheduled to take place on Thursday. Cosmonauts Sergey Prokopyev and Dmitri Petelin will begin their walk at 9 a.m. ET to work on the outside of the Nauka multipurpose laboratory module. The duo will prepare a radiator for transfer from the Rassvet module to Nauka during their seven-hour spacewalk, which will also stream live on NASA’s website.

  • NASA’s moon rocket on track for Wednesday launch attempt

    NASA’s moon rocket on track for Wednesday launch attempt

    [ad_1]

    CAPE CANAVERAL, Fla. — NASA remained on track for Wednesday’s planned liftoff of its new moon rocket, after determining that hurricane damage provided little extra risk to the test flight.

    Hurricane Nicole’s high winds caused a 10-foot (3-meter) section of caulking to peel away near the crew capsule at the top of the rocket last Thursday. The material tore away in small pieces, rather than one big strip, said mission manager Mike Sarafin.

    “We’re comfortable flying as is,” based on flight experience with this material, Sarafin told reporters Monday night.

    Liftoff is scheduled for the early morning hours of Wednesday from NASA’s Kennedy Space Center, with test dummies rather than astronauts on board. It’s the first test flight for the 322-foot (98-meter) rocket, the most powerful ever built by NASA, and will attempt to send the capsule into lunar orbit.

    The nearly monthlong $4 billion mission has been grounded since August by fuel leaks and Hurricane Ian, which forced the rocket back into its hangar for shelter at the end of September. The rocket remained at the pad for Nicole; managers said there wasn’t enough time to move it once it became clear the storm was going to be stronger than anticipated.

    Sarafin acknowledged Monday night that there’s “a small likelihood” that more of the pliable, lightweight caulking might come off during liftoff. The most likely place to be hit would be a particularly large and robust section of the rocket, he noted, resulting in minimal damage.

    Engineers never determined what caused the dangerous hydrogen fuel leaks during the two late summer launch attempts. But the launch team is confident that slowing the flow rate will put less pressure on the sensitive fuel line seals and keep any leakage within acceptable limits, said Jeremy Parsons, a deputy program manager.

    The space agency plans to send astronauts around the moon in 2024 and land a crew on the lunar surface in 2025.

    Astronauts last visited the moon in December 1972, closing out the Apollo program.

    A microwave oven-size NASA satellite, meanwhile, arrived Sunday in a special lunar orbit following a summer liftoff from New Zealand. This elongated orbit, stretching as much as tens of thousands of miles (kilometers), is where the space agency plans to build a depot for lunar crews. The way station, known as Gateway, will serve astronauts going to and from the lunar surface.

    The satellite, called Capstone, will spend six months testing a navigation system in this orbit.
