Faulty Valve Caused Peregrine Lunar Lander Failure

Astrobotic's investigation reveals mechanical issue led to propellant leak, prompting design changes for future missions.

The Peregrine lunar lander failed due to a malfunction in a pressure control valve (PCV2).
The valve failure caused an uncontrolled flow of helium, rupturing the oxidizer tank.
Astrobotic's investigation involved testing a spare valve under similar conditions to identify the issue.
Lessons from Peregrine are being applied to the design of the upcoming Griffin lunar lander.
Griffin will feature improved propulsion systems and backup mechanisms to prevent similar failures.
