SpaceX Super Heavy

Super Heavy is the reusable first stage of the SpaceX Starshipsuper heavy-liftlaunch 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. Production began in 2021, with the first flight being conducted on April 20, 2023, during the first launch attempt of the Starship rocket.

The booster is powered by 33 Raptor engines that use liquid oxygen and methane as propellants. It returns to its launch site after propelling the second stage toward orbit, landing vertically by being caught by the launch tower.
