When Intuitive Machines grew to become the primary personal space firm to land on the moon, it was hailed as profitable, regardless of its spacecraft breaking a leg and falling to its facet.
Now, because the Houston-based firm seeks to repeat the journey, its executives say they’ve made enhancements to their new spacecraft, Athena, that ought to assist it keep away from the issues that impacted the mission in 2024.
“Touchdown on the moon is extraordinarily tough,” Trent Martin, senior vice chairman of Intuitive Machines’ house programs, advised reporters. “Actually we might be higher this time than we have been final time, however you by no means know what may occur.”
The mission, known as IM-2 or PRIME-1, is about to launch on a SpaceX Falcon 9 rocket from Kennedy Area Heart in Cape Canaveral, Florida, as early as Wednesday, Feb. 26. Neither NASA nor Intuitive Machines has introduced a particular time for the liftoff, however the house company intends to broadcast the event reside with commentary. One other spacecraft, NASA’s Lunar Trailblazer, can even hitch a trip on the flight to orbit the moon and map places of lunar water.

When the uncrewed IM-2 launches, it is going to be the third lander en path to the lunar floor, becoming a member of Firefly Aerospace‘s Blue Ghost and ispace‘s Resilience, that are each presently orbiting the moon.
Firefly’s lander is the primary NASA Commercial Lunar Payload Services mission of the year. It’s anticipated to try a touchdown on March 2. Intuitive Machines will observe intently behind, with a descent slated for March 6. This system has invested $2.6 billion in contracts with private-sector distributors to assist ship devices to the moon and ship again essential information.
However touchdown on the moon remains onerous, underscored by the truth that Intuitive Machines is thus far the one firm — versus a authorities house program — that has gotten there largely intact. The moon’s exosphere gives nearly no drag to gradual a spacecraft down because it approaches the bottom. Moreover, there are not any GPS programs on the moon to assist information a craft to its touchdown spot.

A final-minute disaster nearly ruined Intuitive Machine’s 2024 touchdown. Flight controllers had found an issue with the spacecraft’s navigation system just some hours earlier than landing. Mission leaders opted to take one other lap across the moon, which purchased them additional time to change to a NASA laser-based system hooked up to the spacecraft as an experiment.
A mix of gravity and inertia components additionally appeared to stymie the touchdown, mentioned Phil Metzger, a planetary scientist on the College of Central Florida. The Odysseus lander had reached the floor however wasn’t upright. That is partly as a result of the whole lot on the moon is “six occasions tippier,” he mentioned in a post on X then, previously Twitter. The Japanese moon lander SLIM, brief for Good Lander for Investigating the Moon, skilled a similar outcome.
A snapshot from the Intuitive Machines touchdown revealed the spacecraft had damaged a leg on the best way down. The lean had apparently brought about an antenna to be blocked, forcing the workforce to make use of a backup with decrease bandwidth to ship again information.
“IM-1 was a hit as a result of we have been capable of broadcast information from the floor of the moon again to Earth, however,” Martin mentioned, “we did find yourself on our facet.”

Following the mission, Intuitive Machines investigated the whole lot that did not go as deliberate. The workforce decided a problem with the laser altimeter, a instrument that measures precisely how excessive the floor is with a laser beam, in the end resulting in the harder-than-desired landing. Due to that challenge, flight controllers have been utilizing the onboard cameras, which weren’t as exact.
Martin mentioned the investigation resulted in 85 upgrades, together with contingencies that ought to enable Athena to land as much as 10 levels off — maybe extra — and nonetheless full the mission aims. To make certain it could work, the workforce examined all of its deployment mechanisms with such a tilt in all completely different instructions.
“Actually we might be higher this time than we have been final time, however you by no means know what may occur.”
Intuitive Machines additionally addressed the earlier communications points. Tweaks to the spacecraft ought to enable it to land 30 levels off-kilter and nonetheless have the high-gain antenna pointed again at Earth. Moreover, the corporate has upgraded its dishes on the bottom for receiving information.
The lander’s NASA devices embody a drill and mass spectrometer, a tool that identifies the sorts of particles in a substance. The instrument is meant to measure gasses within the lunar soil at Mons Mouton, a plateau on the moon’s south pole the place Athena will attempt to contact down.
However, in any case is alleged and carried out, the lander needs to be upright to make use of them. Nonetheless, Intuitive Machines says it’s going to be a worthwhile journey.
“As an instance one thing occurred like final time, and we ended up on our facet,” Martin mentioned. “Clearly, we’d not be capable to deploy drills. We’d not be capable to deploy hoppers and rovers. Nevertheless, there are many devices on all of these programs that we’d nonetheless be capable to function, identical to final time.”
