When Intuitive Machines turned the primary non-public area 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.
“Landing on the moon is extremely difficult,” Trent Martin, senior vice chairman of Intuitive Machines’ area programs, instructed reporters. “Certainly we will be better this time than we were last time, but you never know what could happen.”
The mission, known as IM-2 or PRIME-1, is ready to launch on a SpaceX Falcon 9 rocket from Kennedy Area Middle 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 area company intends to broadcast the occasion stay with commentary. One other spacecraft, NASA’s Lunar Trailblazer, may even hitch a journey on the flight to orbit the moon and map areas of lunar water.

When the uncrewed IM-2 launches, it will likely 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 at the moment orbiting the moon.
Firefly’s lander is the primary NASA Industrial Lunar Payload Providers mission of the yr. It’s anticipated to try a touchdown on March 2. Intuitive Machines will observe carefully 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 knowledge.
However touchdown on the moon stays onerous, underscored by the truth that Intuitive Machines is to date the one firm — versus a authorities area program — that has gotten there principally intact. The moon’s exosphere offers just about 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 virtually 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 modify to a NASA laser-based system hooked up to the spacecraft as an experiment.
A mixture 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 every little thing on the moon is “six times tippier,” he mentioned in a submit on X then, previously Twitter. The Japanese moon lander SLIM, brief for Sensible Lander for Investigating the Moon, skilled an analogous final result.
A snapshot from the Intuitive Machines touchdown revealed the spacecraft had damaged a leg on the way in which down. The lean had apparently brought on an antenna to be blocked, forcing the crew to make use of a backup with decrease bandwidth to ship again knowledge.
“IM-1 was a success because we were able to broadcast data from the surface of the moon back to Earth, but,” Martin mentioned, “we did end up on our side.”

Following the mission, Intuitive Machines investigated every little thing that did not go as deliberate. The crew 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 touchdown. Due to that difficulty, 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 permit Athena to land as much as 10 levels off — maybe extra — and nonetheless full the mission goals. To make sure it could work, the crew examined all of its deployment mechanisms with such a tilt in all completely different instructions.
“Certainly we will be better this time than we were last time, but you never know what could happen.”
Intuitive Machines additionally addressed the earlier communications points. Tweaks to the spacecraft ought to permit 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 knowledge.
The lander’s NASA devices embrace 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 claimed and accomplished, the lander must be upright to make use of them. Nonetheless, Intuitive Machines says it will be a worthwhile journey.
“Let’s say something happened like last time, and we ended up on our side,” Martin mentioned. “Obviously, we would not be able to deploy drills. We would not be able to deploy hoppers and rovers. However, there are lots of instruments on all of those systems that we would still be able to operate, just like last time.”
