After changes to Starship's components, SpaceX began to build and develop test articles at its Boca Chica launch site. The first publicly known Starship-like concept from SpaceX was a rocket code-named BFR. A Starship can launch more than 100 metric tons (220,000 lb) of payload to low Earth orbit, and place it to higher Earth orbits, the Moon, and Mars after refueling by tanker Starships. Starship can stack, launch and recover its stages via its launch pads and towers. The spacecraft has three Raptors fire in the vacuum of space, pairs of flaps for controlling its descent, and three other engines used to land itself vertically. During liftoff, 33 Raptor engines mounted under Super Heavy produce 72 meganewtons (16,000,000 lb f) of thrust, twice that of a Saturn V rocket. Both stages are made out of stainless steel and consumes liquid oxygen alongside liquid methane for propulsion.
A Starship rocket consists of a first stage named Super Heavy and a second stage named Starship. Starship is a family of reusable launch vehicles in development by American private aerospace company SpaceX. >100 metric tons (220,000 lb) after one or multiple refuellings
