Episode notes
Reusability Could Revolutionize Launch Costs
- Starship aims to be fully reusable and could cut launch costs dramatically compared with past rockets.
- Reuse plus scale could lower cost-per-kilogram from thousands to potentially $10–$100.
Partial Reuse Cut Costs Big
- Falcon 9's reusable first stage drove costs down from tens of thousands to about $1,500–$2,500 per kilogram.
- Partial reuse was a big step, but full reuse promises far larger savings.
Many Engines, Greater Resilience
- Starship uses many smaller Raptor engines (33 on the first stage) instead of a few huge engines.
- Multiple engines lower per-unit cost, increase redundancy, and simplify maintenance cycles.
