Episode notes
CLPS Program
- NASA's Commercial Lunar Payload Services (CLPS) program uses a fixed-price model.
- This differs from traditional NASA missions, shifting cost overruns to the contractors.
Vulcan Centaur Launch
- The Vulcan Centaur rocket, carrying the Peregrine lander, successfully launched.
- However, the Peregrine lander suffered a propellant leak, jeopardizing its moon landing.
Peregrine's Propellant Leak
- A suspected helium valve malfunction over-pressurized the Peregrine lander's oxidizer tank.
- Despite this, other spacecraft systems functioned well, transmitting data from payloads.
