SpaceX Super Heavy

Super Heavy is the reusable first stage of the SpaceX Starship super heavy-lift launch vehicle, which it forms together with the Starship second stage. The booster evolved into its current design over a decade as part of SpaceX's Mars colonization program, with production beginning in 2021 and the first flight on April 20, 2023 during the first launch attempt of the Starship rocket. It is powered by 33 Raptor engines that use liquid oxygen and methane as propellants, and it returns to its launch site after propelling the second stage toward orbit, landing vertically by being caught by the launch tower. The booster is 9 meters wide and composed of four general sections: the engines, the liquid oxygen tank, the liquid methane tank and the interstage. The Block 3 version stands about 72.3 meters tall.
