Intuitive Machines’ first mission (IM-1) featuring the Nova-C Odysseus lunar lander was launched on top of a SpaceX Falcon 9 on February 15th, 2024, as part of NASA’s Commercial Lunar Payload Services (CLPS). Targeting a landing site near the lunar south pole, it was supposed to use its onboard laser range finders to help it navigate safely for a soft touchdown on the lunar surface. Unfortunately, it was this component that was found to have malfunctioned as the spacecraft was already in lunar orbit. Fortunately, there was a with around. By using one of the NASA payloads on the lander, the Navigation Doppler Lidar (NDL), the mission could continue.
Perhaps unsurprisingly, the use of the NDL as a fallback option was considered before launch, and since its functionality overlaps with that of the primary laser range finders of Nova-C, it was pressed into service with a new configuration uploaded by IM operators back on Earth before Nova-C committed to a landing burn. Then, on February 22nd, the spacecraft began its descent to the surface, which also involved the Eaglecam payload that was designed to be released before snapping a self-portrait of the lander as it descended.
Following the landing, there was initially no signal from the lander, which had everyone fearing the worst. Then, a faint signal was detected, which confirmed that the lander had made it safely to the surface. This makes it the first US-built lunar lander in over half a century and the first privately funded US one. The following day, IM reported that they are still communicating with the lander, and everything looks good so far. This ..
