Artwork of SpaceX's reusable rocket Starship launching from Cape Canaveral, Florida. Starship is designed to be the most powerful launch vehicle ever built, and it is fully reusable. When launching from Earth, the systems consists of Starship itself (top) perched atop a booster stage called the Super Heavy. Starship by itself cannot escape Earth's gravity, which is why it needs the additional booster at launch (which is also reusable), but it can land by itself and has already done so in tests on Earth.
