Overview

• 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.
