Tiny Fault Dooms First Private Lunar Lander


Although the lunar lander didn’t make it to its intended destination, Acrobatics Mission Control was able to retrieve its craft from space after fears that it could become space debris and collide with other craft in Earth’s orbit required its recall.

The compromised craft was able to maneuver some, though not to its full capacity, and it was guided back to Earth over the open ocean to avoid damaging structures or injuring people. Valuable data was collected by NASA and Astrobotics from the mission, even though it didn’t reach the Moon.

The faulty valve that thwarted the mission of the Peregrine lunar lander is known as PCV2. Engineers working on the construction of the Peregrine craft had problems with their first supplier of these valves, with many failures prompting them to switch suppliers as late as August of 2022. The new PCV valves encountered problems sealing as well, though it was a known risk to the mission.
