SpaceX Starship is a big rocket made by a company called SpaceX. It's like a really big, powerful car. SpaceX plans to use the Starship to take people and things, like satellites, into space. You could think of it as a 'space bus'. It's made up of two pieces: the 'super heavy' rocket booster, which is like a big fuel tank, and the 'Starship', which is like the coach, where people or things would be taken up into space. The super heavy booster helps to push the Starship up into space and once it's up there, the Starship can take off and travel to other places in space, like the Moon and Mars.
