"It isn't for Mars" is just a reasonable inference about how hard it will be for Starship to go farther than Earth orbit. It's over-weight, which reduces payload, which makes in-orbit refueling need way too many refueling flights, which takes too much time and requires building too many refueling rockets that each have 39 Raptor engines @ $2M each if you believe Elon's numbers. It all very readily succumbs to the rocket equation unless the very most optimistic numbers of $5M per launch and 8 launches carrying 150 tons of fuel each are actually met. If not, the only real use of a rocket that big is DoD payloads to Earth orbit. |
