  A spaceship wouldn’t stop anyway as it’s being flung around by gravity. However, if a satellite was dependent on fuel, such as a thruster system, and it ran out of fuel needed to maneuver correctly, then yes filling it back up would allow it to move it in its targeted direction. There’s been a few missions that re-visit spacecraft to fix them, Hubble telescope springs to mind, but I don’t recall a mission yet where the fuel tanks have been refilled.

How do the thruster work if there is no friction? I thought that in order for something to move there has to be friction between two objects. Like a foot and the ground or a tyre on the road.
