Falcon Heavy combines a core stage and two side boosters derived from Falcon 9, with 27 Merlin engines in total. The February 2018 demonstration flight sent a Tesla Roadster into heliocentric orbit and showed both side boosters landing simultaneously.

The launcher flies less often than Falcon 9 and serves mainly heavy or energy-demanding payloads: geostationary satellites, national-security missions, and NASA science probes. Starship is intended to take over the heaviest payloads in future, but remains in flight testing.

Key context

  1. First flight: 6 February 2018 from pad 39A at Kennedy Space Center.
  2. Three boosters with nine Merlin engines each, 27 engines at liftoff.
  3. Side boosters land on shore; the core stage lands on a droneship or is expended depending on the mission profile.
