According to Astrobotic, a clogged valve may have scuttled its private Peregrine lunar lander mission. On January 8, United Launch Alliance’s Vulcan Centaur rocket launched the mission to become the first private spacecraft to land softly on the moon. Astrobotic had to solve a fuel leak after the Peregrine launched from the rocket’s upper stage.
Peregrine Moon Lander’s Anomaly Linked to Failed Valve, Reveals Astrobotic
After initiation, the helium pressurant-oxidizer valve failed to reseal, according to the company’s hypothesis. This failure ruptured the oxidizer tank by releasing high-pressure helium above its operating limit. This was Astrobotic’s eighth upgrade since the anomaly was discovered.
The fuel leak prevented the moon landing, but Astrobotic announced that the lander was stable and had 40 hours of fuel. The corporation has kept the public informed throughout.
NASA supplied five scientific instruments to Peregrine’s 20 payloads through its Commercial Lunar Payload Services (CLPS) program. Due to mission problems, none of these payloads will reach their target.

Astrobotic noted that Vulcan Centaur, making its long-awaited debut, successfully put the lander into the planned translunar trajectory without any evidence that the launch caused the propulsion anomaly experienced by Peregrine.
A blocked valve that leaked fuel hampered Astrobotic’s private Peregrine moon lander mission. The company’s study reveals a helium pressurant-oxidizer valve failure caused the tank to explode. Regular updates have kept the company transparent despite mission setbacks. Aside from the oddity, ULA’s Vulcan Centaur rocket successfully launched Peregrine on its intended path.
