WebbWithout propulsion, nothing goes anywhere. It provides the extreme acceleration a rocket needs to lift off and release a spacecraft into orbit around Earth or sling it into deeper space. Spacecraft themselves then use their own propulsion systems to adjust their orbits around Earth, travel through space, or make carefully controlled landings on ...
