>Is this possible with the starship?
1g = 9.8 m/s per second, Starship can accelerate faster than that for a few minutes in order to reach space but then it's out of propellant. So just add more? They can't because the amount required to increase delta-v is exponential, see the rocket equation.

Instead you can take two Starships, attach a wire between them and spin them at 1g. You could also make spin station Mars cycler, those don't reduce the delta-v required to reach Mars, they make it so that you only have to get your habitation module in space once and Starship would just have to carry the supplies.

People tend to think of space as all one kind of place, as long as it's zero gravity or microgravity, and no breathable air. And then we imagine a single vehicle that goes to every space possible, because that's the easiest kind of science fiction related.

One thing Kubrick got right: five kinds of spacecraft for 5 kinds of mission.

Pic related: the Aldrin cycle ship can be as huge as you like, it never needs significant delta-vee. It's basically a planetoid in a very convenient orbit.
