SpaceX is developing Starship, a fully reusable two-stage rocket designed to replace the Falcon 9 and Falcon Heavy, capable of carrying 100-150 tonnes to low Earth orbit. The rocket consists of the Super Heavy booster and the Starship upper stage, which will have multiple versions for satellite deployment, refueling, and passenger transport. Testing has progressed with prototypes, including the Starhopper, which successfully completed several hops, and full-scale prototypes are nearing completion for high-altitude flights. The ambitious long-term goal includes crewed missions to Mars and rapid Earth-to-Earth travel. If successful, Starship could significantly reduce spaceflight costs and improve safety, aiming for a failure rate comparable to modern aircraft.
