Episode notes
Flight 10 Was A Major Technical Win
- Flight 10 was a major technical win: Starship completed staging and guided itself to a controlled splashdown over an hour after liftoff.
- Nearly every ceramic tile survived reentry, showing the overall shield approach is promising despite some visible thermal wear.
Three Metal Tiles Experiment Failed
- SpaceX deliberately mounted three experimental metallic tiles to compare them with ceramic tiles on Flight 10.
- The metal tiles oxidized heavily and failed to insulate effectively during reentry.
Gaps Drive Localized Heating And Ablation
- Engineers found heat concentrated and eroded where tile gaps were largest, sometimes ablation reached the backup thermal barrier.
- Exposed test areas produced white blotches from ablation, confirming direct heating effects on underlying layers.
