For some failures we (outsiders) can speculate about possible causes even without official statements, because there's only a few things that could create the scenario we saw, but in this case it's too vague. | |

| Aug 8, 2023 at 22:09 | comment | added | Organic Marble | " A premature engine shutdown is a bit like a car's "Check Engine" light; it doesn't really tell us anything except "something went wrong"." It may not tell us but I would bet that it tells SpaceX what went wrong. Even the 1970s vintage SSME controller sent failure identification codes to telemetry explaining why it shut the engine down. | |
