SpaceX Raptor engines power the world’s biggest rocket Starship using liquid oxygen and methane for faster more efficient thrust than older designs. Unlike NASA’s RP-1 engines Raptors generate greater acceleration with improved turbine rotation. Future space travel may also rely on NASA’s nuclear engines—thermal and electric exhaust systems capable of cutting Mars trips to 100 days and reducing Pluto missions from 10 years to just 4.
