Episode notes
Why Artemis II Rolled Back After A Successful Wet Dress
- Artemis II wet dress rehearsal itself succeeded but a helium flow issue during detanking required rolling the SLS back to the high bay for repairs.
- Matt and Robyn emphasize cryogenic hydrogen systems' tiny molecules make purging and leak localization especially difficult, explaining conservative post-test rollbacks.
Starliner Mishap Reveals Programmatic Cultural Failures
- Starliner's mishap was classified at the highest level because damage and mission impacts exceeded thresholds and required crew return re-planning.
- Matt argues Boeing's management and program incentives created a 'jobs program' mentality that eroded engineering focus, contrasting it with SpaceX's iterative flight-proven Dragon.
Pause And Buy Down Risk For Human Spaceflight
- Treat human spaceflight decisions with higher conservatism and pause to get systems right before flight.
- Robyn notes detanking, rollback, and crew return choices are appropriate risk posture changes when safety margins are uncertain.
