If you're going to throw a tank of propellant into space, why not just throw a tank that can be swapped in? That bypasses the whole "refueling" problem.

- andruby 3y agoWhat do you mean “swapped in”? A large part of the propellant is used by the time the tank is up in space. The plan is to transfer the remaining (10%?) of fuel.
- wilg 3y agoBecause the tanks are structural parts of the rocket to save weight, and saving weight is a huge part of getting the performance you want. Also would probably be just about as hard to swap tanks.
