Following a successful launch and separation from the ULA Vulcan Centaur rocket on Jan. 8, 2024, Peregrine experienced a loss of propellant. Not only did that prevent any soft landing on the Moon, but the valve connecting helium to oxidizer had caused flooding and ruptured the tank. The spacecraft was now a flying hazard that could potentially create more debris in cislunar space or lunar orbit. After analysis and recommendations from NASA and the space community, Astrobotic determined the best option for minimizing risk and ensuring responsible disposal of the spacecraft would be to maintain Peregrine's trajectory toward Earth for atmospheric re-entry and burnup.
