		readams on May 13, 2021 \| parent \| context \| favorite \| on: Movies every physics lover should watch (2020) The taking off from Earth in multiple stages but not other planets is actually pretty realistic. Earth is big. For example, Starship plans to do exactly this: using the super heavy booster to take off from earth but single stage from mars or the moon.

They make a point of saying the first planet visited has higher than Earth gravity.

Yes, but the ship was much heavier when leaving Earth.

For the first take-off, it needed to carry enough fuel for the rest of the trip. By the second take-off, most of that fuel had been used.
