ATHENA LANDED IN A DARK CRATER WHERE THE TEMPERATURE WAS MINUS 280° F

Summary from the TLDR newsletter

Intuitive Machines' Athena spacecraft's altimeter failed during landing last week, causing it to misjudge its altitude and land in a small shadowed crater after toppling over and rotating once or twice. This caused regolith to be blown up into the solar panels, which meant the panels weren't able to provide the lander sufficient power to survive. The lander was able to accomplish some of its objectives as mission operators decided to operate as robustly as possible for 13 hours to get as much data as they could. Despite the bad landing, the mission was largely a success - Athena flew smoothly, the company validated the spacecraft's methane-based propulsion system, and it also proved that its communications technology can be used as part of the lunar data relay network that NASA has contracted with Intuitive Machines to develop.
