]]>Odysseus was carrying NASA instruments, which the space agency said would be used to help prepare for future crewed missions to the moon under the Artemis program. NASA confirmed the landing happened at 6:23 PM ET on February 22. The lander launched from Earth on February 15, with the help of a SpaceX Falcon 9 rocket.
According to The New York Times, there were some “technical issues with the flight” that delayed the landing for a couple of hours. Intuitive Machines CTO Tim Crain told the paper that “Odysseus is definitely on the moon and operating but it remains to be seen whether the mission can achieve its objectives.” Odysseus has a limited window of about a week to send data back down to Earth before darkness sets in and makes the solar-powered craft inoperable.
Intuitive Machines wasn’t the first private company to attempt a landing. Astrobotic made an attempt last month with its Peregrine lander, but was unsuccessful. Intuitive Machines is planning to launch two other lunar landers this year.

]]>While the initial assessment was that Odysseus had landed properly, further analysis indicated otherwise. Intuitive Machines CEO and co-founder Steve Altemus said “stale telemetry” was to blame for the earlier reading.
All payloads except the one static art installation, though — Jeff Koons’ Moon Phases sculptures — are on the upturned side. The lander and its NASA science payloads have been collecting data from the journey, descent and landing, which the team will use to try and get a better understanding of what happened. But, all things considered, it seems to be doing well.
The team plans to eject the EagleCam, developed by students at Embry-Riddle Aeronautical University, so it can take a picture of the lander and its surroundings perhaps as soon as this weekend. It was supposed to be ejected during descent to capture the moment of landing, but issues on touchdown day prevented it from being released.
Once Odysseus was in lunar orbit and hours away from its landing attempt, the team discovered its laser range finders, which are key to its precision navigation, were not working — due entirely to human error. According to Altemus, someone forgot to flip a safety switch that would allow them to turn on, so they couldn’t. That realization was “like a punch in the stomach,” Altemus said, and they thought they could lose the mission.
The team was thankfully able to make a last-second adjustment cooked up on the fly by Intuitive Machines CTO and co-founder Tim Crain, who suggested they use one of the on-board NASA payloads instead to guide the descent, the Navigation Doppler LIDAR (NDL). In the end, Odysseus made it there alright. Its mission is expected to last a little over a week, until lunar night falls.

]]>To be exact, Intuitive Machines has set its sights on the Malapert A crater near the moon's south pole as Odysseus' landing site. The spacecraft can operate for around 14 Earth days when powered by sunlight, but the company is hoping for touchdown to take place by February 22. Odysseus, the first of the Nova-C type landers Intuitive Machines is planning to launch this year, is carrying five NASA payloads in addition to commercial cargo.
The mission's objectives include demonstrating precision landing and testing certain communication and navigation node capabilities. It will also observe how rocket plumes and space weather interact with the lunar surface. IM-1 was one of the missions NASA had chosen to take its scientific instruments to the moon over the next few years as part of its Commercial Lunar Payload Services (CLPS) initiative. The first of the CLPS missions to take off was Astrobotic's Peregrine Mission 1, which unfortunately experienced an anomaly that prevented the lander from pointing its solar panels at the sun and caused it to leak propellant. Peregrine never made it to the moon and ended its journey by burning up in the Earth's atmosphere upon reentry.

]]>Odysseus is on track to make its moon landing attempt on February 22, and so far appears to be performing well. The team posted a series of updates on X at the end of the week confirming the lander has passed some key milestones ahead of its touchdown, including engine firing. This marked “the first-ever in-space ignition of a liquid methane and liquid oxygen engine,” according to Intuitive Machines.

]]>While the solar powered landers weren’t built to withstand the frigid lunar night, SLIM — which has been on the moon since January 19 — has already beaten the odds before to pull through last month. It’ll be the first lunar night for Odysseus, which landed on February 22.
The missions, though successful in that the spacecraft survived their respective descents to the surface, stand as further examples of how challenging it is to land on the moon; both landers fell over, leaving them stuck in non-ideal positions. SLIM face-planted, and Odysseus broke a leg and tipped onto its side.
SLIM has been able to capture a few images from the surface, and the team shared another look at the Shioli crater from its perspective on Thursday before it powered down. Odysseus has sent home some pictures too from its wide-angle camera, including one last transmission before lunar night that shows a portion of the lander and the surface of the moon, with a tiny crescent Earth in the distance. But the world has eagerly been awaiting third-person POV pictures from the EagleCam made by students at Embry-Riddle Aeronautical University, which hitched a ride with Odysseus. Unfortunately, that doesn’t seem likely to happen at this point.
The camera wasn’t deployed as originally planned before the moment of touchdown, and while Intuitive Machines said this week that the team was able to power it up and eject it after Odysseus reached the surface, communications with the camera so far aren’t working. “The Embry‑Riddle team is working on that and wrestling with that to see if there’s anything they can do,” Intuitive Machines CEO Steve Altemus said on Wednesday. The onset of lunar night isn’t going to help those odds.
