Falcon Heavy

Information

Falcon Heavy is a derivative of the Falcon 9 launch vehicle. It comprises of a Centre Core (a strengthened F9 booster to support additional loads) and two side boosters referred to as the Minus Y (MY or -Y) and Positive Y (PY or +Y). Falcon Heavy side boosters and Falcon 9 boosters are interchangeable, and SpaceX have converted boosters between the two several times. Similarly to Falcon 9, Falcon Heavy is designed to be partially reuseable with many Falcon Heavy launches featuring synchronised landings of the two side boosters; the first such landing was achieved on the maiden flight of Falcon Heavy on February 6th 2018. SpaceX have attempted to recover the Centre Core on 3 occasions to date (the first three Falcon Heavy flights) with only one landing being successful so far. Unfortunately, the booster was lost during the return home meaning SpaceX are yet to successfully recover and re-fly a centre core. So far, all Falcon Heavy launches have been fully successful.
