Starship hauling ~150t to LEO for a tiny fraction of cost compared to now will change everything. People really don't get it yet. As soon as #SpaceX reaches LEO with full reuse alone, the game has changed.
Replying to @SPEXcast @TrungTPhan
Starship will be crushingly cost-effective for Earth orbit or moon missions as soon as it’s operational & rapid reuse is happening.
Mars is a lot harder, because Earth & Mars only align every 26 months, so ship reuse is limited to ~dozen times over 25 to 30 year life of ship.
