Super Heavy is the reusable first stage of the SpaceX Starship super heavy-lift launch vehicle, which it composes in combination with the Starship second stage. As a part of SpaceX's Mars colonization program, the booster evolved into its current design over a decade.[4][5][6] Production began in 2021, with the first flight being conducted on April 20, 2023, during the first launch attempt of the Starship rocket.[7][8]
The booster is powered by thirty-three Raptor engines that use liquid oxygen and methane as propellants. After propelling the second stage towards orbit, it can return to its launch site, where it lands vertically by being caught by its launch tower, allowing for full reusability.
