Hundreds of thousands of miles beyond Earth, a phone booth-size spacecraft is en route to take on a challenge no vehicle launched from the United States has attempted in more than 50 years.The lunar lander called Odysseus or IM-1, created by Houston-based company Intuitive Machines, landed on the moon this week. Coverage of the historic event was livestreamed on NASA TV.Success is not guaranteed. Had it failed, Odysseus would have become the third lunar lander to meet a fiery demise on the moon in less than a year. Russiaâs first lunar lander mission in 47 years, Luna 25, failed in August 2023 when it crash-landed. Hakuto-R, a lander developed by Japan-based company Ispace, met a similar fate last April.Overall, more than half of all lunar landing attempts have ended in failure â tough odds for a feat humanity first pulled off nearly 60 years ago.The Soviet Unionâs Luna 9 became the first spacecraft to make a controlled, or âsoft,â landing in February 1966. The United States followed shortly after when its robotic Surveyor 1 spacecraft touched down on the moonâs surface just four months later.Since then, only three other countries â China, India and Japan â have achieved such a milestone. All three reached the moon with robotic vehicles for the first time in the 21st century. India and Japan each pulled off the monumental feat just within the past six months, long after the U.S.-Soviet space race had petered out. The U.S. remains the only country to have put humans on the lunar surface, most recently in 1972 with the Apollo 17 mission.But the U.S. government hasnât even tried for a soft landing â with or without astronauts on board â since then. Private space company Astrobotic Technology had hoped its Peregrine lunar lander would make history after its recent January launch, but the company waved off the landing attempt mere hours after liftoff because of a critical fuel leak and brought the spacecraft back to burn up in Earthâs atmosphere.Regaining past knowledge and experience is a big part of the challenge for the U.S., Scott Pace, the director of George Washington Universityâs Space Policy Institute, told CNN.âWeâre learning to do things that we havenât done in a long time, and what youâre seeing is organizations learning how to fly again,â Pace said. âGoing to the moon is not a matter of just a brave or brilliant astronaut. Itâs a matter of entire organizations that are organized, trained, and equipped to go out there. What weâre doing now is essentially rebuilding some of the expertise that we had during Apollo but lost over the last 50 years.âTechnical know-how, however, is only part of the equation when it comes to landing on the moon. Most of the hurdles are financial.A new modelAt the peak of the Apollo program, NASAâs budget comprised over 4% of all government spending. Today, the space agencyâs budget is one-tenth the size, accounting for only 0.4% of all federal spending, even as it attempts to return American astronauts to the moon under the Artemis program.âThere were literally hundreds of thousands of people working on Apollo. It was a $100 billion program in 1960s numbers. It would be a multi-trillion-dollar program in todayâs dollars,â said Greg Autry, the director of space leadership at Arizona State Universityâs Thunderbird School of Global Management. âThereâs simply nothing that compares to it.âThe lunar landers of the 21st century are attempting to accomplish many of the same goals at a small fraction of the price.Indiaâs Chandrayaan-3 lander, which became the first spacecraft from the country to safely reach the lunar surface in August 2023, cost about $72 million, according to Jitendra Singh, the Minister of State for Science and Technology.âThe cost of Chandrayaan-3 is merely Rs 600 crore ($72 million USD), whereas a Hollywood film on space and moon costs more than Rs 600 crore,â Singh told The Economic Times, a media outlet in India, in August.In the U.S., NASA is attempting to drastically reduce prices by outsourcing the design of small, robotic spacecraft to the private sector through its Commercial Lunar Payload Services program, or CLPS.Astrobotic was the first company to fly under the CLPS initiative, and after its January setback, Intuitive Machines has picked up the torch â soft-landing Odysseus near the lunar south pole on Thursday, though the craft is now reportedly on its side.âWeâre going a thousand times further than the International Space Station,â Intuitive Machines president and CEO Steve Altemus told CNN. âAnd then, on top of that, you set the target: Do it for $100 million when in the past itâs been done for billions of dollars.âWhy we canât just repeat ApolloItâs also unrealistic to expect that NASA or one of its partners could simply drag out the blueprints of a 1960s lunar lander and recreate it from scratch. Most of the technology used on those missions has long been retired, cast aside by the massive leaps in computing power and material sciences made in the past half-century.Each piece of hardware on a lunar lander must be sourced from modern supply chains â which look far different than those of the 20th century â or designed and manufactured anew.

And so we really havenât had that kind of repetition in lunar landings.âA perilous descentAnd while technology has advanced in the past five decades, the fundamental challenges of landing on the moon remain the same. First, there is the sheer distance â itâs roughly a quarter of a million-mile journey from Earth to the moon. If you could drive a car to the moon at a constant speed of 60 miles per hour, it would take more than five months.âSome people have likened it to hitting a golf ball in New York and having it go into a specific hole in Los Angeles. That kind of precision in long distance is unbelievably difficult to do,â Pace said.Then, there is the tricky lunar terrain. The moon is covered in dead volcanoes and deep craters, making it difficult to find flat landing zones.âApollo 11 would absolutely have crashed and been destroyed if it had landed on the spot it originally came down on,â Autry said. âNeil (Armstrong) was literally looking out the window. He maneuvered the lander over a boulder field and a big crater and found a safe spot to land with just barely enough fuel left. If there wasnât a skilled pilot that could control it, the lander certainly would have wrecked.âWithout the assistance of human eyes inside the spacecraft, modern-day robotic lunar landers use cameras, computers, and sensors equipped with software and artificial intelligence to safely find their landing spot â and avoid boulders and craters â during the final descent. And even humans in mission control rooms back on Earth canât help the spacecraft in those final, critical seconds before touchdown.âIt takes time for a signal to go up and come back, about three seconds total round trip,â Pace said. âA lot can go wrong in that time. So when the vehicle is actually landing, itâs pretty much on its own.âFailure is an optionIn the early days of the 20th-century space race, far more spacecraft failed than safely touched down on the moon.
