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 business quite 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 ft 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 non-public 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 bunch 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 permit 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 determine contact with Odysseus. “Indicators of life—we have now 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 delicate 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 predominant engine—which burns liquid methane and liquid oxygen—is the primary of its variety 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 could 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 atmosphere, 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 repeatedly belched out by our star. These information will embrace essential radio measurements that may seize among the photo voltaic wind’s interactions with the moon’s floor.
NASA is focusing on the lunar south pole as a result of some shadow-cloaked areas there include water ice—a key useful resource for long-term human sojourns on the moon. For the company’s Artemis III mission, which can launch no ahead of 2026, NASA has contracted with SpaceX to land a two-person crew close to the lunar south pole.
“[IM-1] is a tech demo, in case you like, however it’s going to get our first information concerning the atmosphere of the south pole of the moon. That’s going to be essential for designing methods 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 companies. However due to plummeting launch prices and the regular march of technological progress, it’s now cheaper than ever for nations 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 Threat, 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 House Middle in Florida. Over the subsequent a number of days, Odysseus traveled a complete of a couple of million kilometers (621,000 miles) to insert itself into lunar orbit, which it efficiently did on February 21. The spacecraft is anticipated 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 night time.
The mission is flying below the banner of NASA’s Business Lunar Payload Companies (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. Thus far 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 attain decrease prices and a better cadence of missions. Up to now, NASA has paid Intuitive Machines $118 million below the contract that created IM-1—far lower than the company has spent on robotic landers prior to now. And IM-1 is the second of as much as 5 CLPS missions which will find yourself launching this 12 months.
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 companies. In August 2023 the Russian moon mission Luna-25 crashed into the lunar floor after an engine misfire. In January a Japanese lunar lander referred to as SLIM (Sensible Lander for Investigating Moon) touched down safely however at an sudden angle, which restricted its capacity to gather solar energy.
And in trade for decrease prices and extra missions, NASA took on a better threat that anyone CLPS mission would fail. From CLPS’s inception, NASA officers cautioned that even a 50 % mission success charge was acceptable for this system.
Thus far that prediction is panning out. Again in January the Pittsburgh-based firm Astrobotic tried the primary mission below 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 every week and a half, however the mission ended with Peregrine burning up in Earth’s ambiance.
“[NASA] anticipated an roughly 50 % failure charge, and one for 2 is that charge,” says Laura Forczyk, government director of the house business 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 formidable targets. As quickly as later this 12 months, 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 12 months, 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 check missions,” Forczyk says. “We need to be sure that the know-how is confirmed and mature earlier than we put higher-stakes payloads onboard.”
