For the primary time since 1972 a spacecraft launched from the U.S. has landed softly on the floor of the moon. And, for the primary time ever, this profitable extraterrestrial touchdown was achieved by a spacecraft constructed and operated by non-public trade reasonably than by a authorities house program.
At 6:23 P.M. EST a 14.1-foot-tall lander resembling a police sales space on stilts descended to the moon’s floor on a ballooning blue flame of rocket exhaust. Seconds later, the lander’s six toes crunched into the darkish soil of Malapert A, a crater nestled deep within the moon’s southern latitudes.
This robotic voyager, aptly nicknamed Odysseus, carries six scientific payloads on behalf of NASA. However crucially, the U.S. house company isn’t operating the mission: Odysseus is the primary industrial spacecraft ever to land safely on one other celestial physique.

Odysseus was constructed and operated by Intuitive Machines, a personal spaceflight firm based mostly in Houston, as a part of the corporate’s IM-1 mission. Along with NASA gear, Odysseus carries payloads from non-public shoppers that vary from a gaggle of sculptures by artist Jeff Koons to a robotic “selfie” digicam constructed by college students at Embry-Riddle Aeronautical College.
And like its namesake from the traditional Greek epics, Odysseus confronted trials because it sailed towards the lunar floor. Mere hours earlier than touchdown, two onboard ranging lasers that Odysseus had deliberate to make use of to detect the moon’s floor broke. In response, Intuitive Machines improvised a software program patch that allow Odysseus commandeer two lasers onboard an experimental navigation payload constructed by NASA.
For greater than quarter-hour after landing, Intuitive Machines’ mission management in Houston, Texas, waited in tense silence, as flight controllers tried to ascertain contact with Odysseus. “Indicators of life—now we have a return sign we’re monitoring,” quipped Tim Crain, Intuitive Machines’ chief know-how officer IM-1 mission director. “We’re additionally not useless but.”
Minutes later, Crain confirmed that Odysseus was transmitting from the moon’s floor, albeit weakly. At press, the explanation for the sign’s weak spot stays unclear.
IM-1 is the primary U.S. mission to the touch down softly on the lunar floor since Apollo 17 in 1972. And in contrast to IM-1, Apollo 17 was crewed. The nation’s final robotic gentle touchdown on the moon happened in January 1968, with the landing of the NASA lander Surveyor 7.
“Odysseus has taken the moon,” NASA administrator Invoice Nelson stated in a pre-recorded congratulatory message. “This feat is a huge leap ahead for all of humanity.”
The mission additionally achieves some technical firsts. The spacecraft’s fundamental engine—which burns liquid methane and liquid oxygen—is the primary of its type for use in a moon touchdown. IM-1 additionally marks the southernmost moon touchdown ever accomplished. The lunar lander of India’s Chandrayaan-3 mission, the primary on this normal area, touched down at 69 levels south latitude, which on Earth can be like touchdown on the Antarctic Peninsula. IM-1, nonetheless, is sitting at greater than 80 levels south latitude—the lunar equal of the deep Antarctic inside.
IM-1’s onboard NASA devices will present the primary in situ measurements of this forbidding setting, the place the solar’s excessive angle on the horizon can create enormous swings in floor temperatures, in addition to in publicity to the “photo voltaic wind” of charged particles which might be constantly belched out by our star. These knowledge will embrace essential radio measurements that may seize a number of the photo voltaic wind’s interactions with the moon’s floor.
NASA is concentrating on the lunar south pole as a result of some shadow-cloaked areas there comprise water ice—a key useful resource for long-term human sojourns on the moon. For the company’s Artemis III mission, which is able to launch no prior to 2026, NASA has contracted with SpaceX to land a two-person crew close to the lunar south pole.
“[IM-1] is a tech demo, if you happen to like, however it should get our first knowledge in regards to the setting of the south pole of the moon. That’s going to be essential for designing techniques to permit people to outlive and thrive there,” says College of Notre Dame lunar scientist Clive Neal.
Maybe IM-1’s greatest contribution is the precedent it units for the way forward for house exploration. For many years, house had been thought of the purview of solely a handful of presidency businesses. However because of plummeting launch prices and the regular march of technological progress, it’s now cheaper than ever for international locations and personal corporations to construct and function spacecraft—and even ship them to interplanetary locations.
“[IM-1 is] a watershed in industrial improvement inside the US,” Neal says.
Excessive Danger, Excessive Reward
At 1:05 A.M. EST on February 15 IM-1 launched atop one in every of SpaceX’s Falcon 9 rockets from NASA’s Kennedy Area Middle in Florida. Over the subsequent a number of days, Odysseus traveled a complete of multiple million kilometers (621,000 miles) to insert itself into lunar orbit, which it efficiently did on February 21. The spacecraft is predicted to function on the moon’s floor for as much as seven days earlier than it succumbs to the darkness and brutal chilly of lunar evening.
The mission is flying beneath the banner of NASA’s Business Lunar Payload Providers (CLPS) initiative, which has inspired non-public funding in lunar missions since its founding in 2018. Below CLPS, the company awards non-public corporations contracts to ship NASA gear and science devices to the moon’s floor. Up to now 14 corporations have joined this system, which guarantees to pay as much as $2.6 billion for supply providers by 2028.
Not like conventional NASA applications, the house company doesn’t personal and function CLPS spacecraft—the businesses do. In return, NASA hopes to realize decrease prices and a better cadence of missions. Up to now, NASA has paid Intuitive Machines $118 million beneath the contract that created IM-1—far lower than the company has spent on robotic landers up to now. And IM-1 is the second of as much as 5 CLPS missions that will find yourself launching this yr.
That stated, CLPS corporations have been given a steep hill to climb. Traditionally, solely 5 out of each 9 moon missions have succeeded, even amongst these of well-funded authorities house businesses. In August 2023 the Russian moon mission Luna-25 crashed into the lunar floor after an engine misfire. In January a Japanese lunar lander often known as SLIM (Good Lander for Investigating Moon) touched down safely however at an surprising angle, which restricted its potential to gather solar energy.
And in alternate for decrease prices and extra missions, NASA took on a better threat that anybody CLPS mission would fail. From CLPS’s inception, NASA officers cautioned that even a 50 p.c mission success charge was acceptable for this system.
Up to now that prediction is panning out. Again in January the Pittsburgh-based firm Astrobotic tried the primary mission beneath CLPS, Peregrine Mission 1. Quickly after launch, nonetheless, Astrobotic’s Peregrine spacecraft sprang a propellant leak. The corporate managed to maintain the lander alive in house for per week and a half, however the mission ended with Peregrine burning up in Earth’s ambiance.
“[NASA] anticipated an roughly 50 p.c failure charge, and one for 2 is that charge,” says Laura Forczyk, govt director of the house trade consulting agency Astralytical. “[IM-1 proves] that there’s a functionality for industrial landers to securely land on the floor of the moon at a decrease value.”
Peregrine and IM-1 are simply the primary in an upcoming wave of business moon missions with more and more bold targets. As quickly as later this yr, Astrobotic is on faucet to ship VIPER (Volatiles Investigating Polar Exploration Rover), a water-hunting rover constructed by NASA, to the lunar south pole. Intuitive Machines’ upcoming IM-2 mission, additionally slated for later this yr, will ship PRIME-1 (Polar Sources Ice Mining Experiment 1), a NASA drill designed to dig into the moon’s subsurface.
“These preliminary missions are extra take a look at missions,” Forczyk says. “We wish to make it possible for the know-how is confirmed and mature earlier than we put higher-stakes payloads onboard.”
