Overview

About Falcon Heavy

Falcon Heavy is SpaceX's heavy-lift rocket, built by joining a strengthened Falcon 9 centre core to two Falcon 9 first stages acting as side boosters — 27 Merlin engines firing together at liftoff. The two side boosters routinely return for synchronised landings, while the centre core is recovered when the mission's energy budget allows.

It is used for the heaviest commercial and US government payloads, including large geostationary communications satellites, NASA science missions, and US Space Force national-security launches that exceed Falcon 9's reach.

Falcon Heavy launches exploration misison

SpaceX@SpaceXAug 30

Falcon Heavy sent Psyche toward a metal-rich asteroid, Europa Clipper to Jupiter’s Moon, and GOES-U into transfer orbit to improve NOAA’s weather forecasting. Falcon 9 launched NASA’s PACE mission to study Earth’s ocean and atmosphere and SPHEREx to map the history of the universe. The Falcon family has enabled NASA to reach farther and explore more of the universe, and missions like Roman continue that work

The telescope will travel to the second Sun-Earth Lagrange point, which is ~one million miles away and about four times farther from Earth than the Moon. At L2, the combined gravity of the Sun and Earth will give Roman a stable vantage point with a clear, unobstructed view to survey deep space and accomplish its mission
