Intuitive Machines’ second attempt to land on the Moon also went sideways
Inside a small control room, during the middle of the day on Thursday local time in Texas, about a dozen white-knuckled engineers at a space startup named Intuitive Machines started to get worried. Their spacecraft, a lander named Athena, was beginning its final descent down to the lunar surface.
A little more than a year had passed since the company's first attempt to land on the Moon with a similarly built vehicle, Odysseus. Due to problems with that spacecraft's laser rangefinder, it skidded into the Moon's surface and toppled over.
So engineers at Intuitive Machines had checked, and re-checked the laser-based altimeters on Athena. When the lander got down within about 30 km of the lunar surface, they tested the rangefinders again. Worryingly, there was some noise in the readings as the laser bounced off the Moon. However, the engineers had reason to believe that, maybe, the readings would improve as the spacecraft got nearer to the surface.
