@thomasfuchs I understand (and agree with) much of the criticism of Elon Musk. However, SpaceX has been an unqualified success. While NASA tends to “go slow and get it perfect” at great expense, SpaceX embraces iterative design where failures are expected and used to improve the final outcome. Each approach has merit, but my opinion is that SpaceX will get Starship working reliably and launching several times before even the third $4 billion dollar SLS launch.
