Falcon Heavy

First stage

| |

Three cores make up the first stage of Falcon Heavy. The side cores, or boosters, are connected on the nosecone, the interstage, and on the octaweb. Shortly after liftoff the center core engines are throttled down. After the side cores separate, the center core engines throttle back up to full thrust.

Falcon Heavy

Interstage

The interstage is a composite structure that connects the center core on the first stage and second stages and holds the release and separation system.

Grid fins

Falcon Heavy is equipped with 12 hypersonic grid fins, four on each booster, positioned at the base of the interstage or nosecone which orients by moving the center of pressure during reentry.

Falcon Heavy

Second stage

Falcon Heavy draws upon Falcon 9’s proven design, which minimizes stage separation events and maximizes reliability. The second-stage Merlin Vacuum Engine delivers the rocket’s payload to orbit after the main engines cut off and the first-stage cores separate.

Falcon Heavy

Payload

Made of a carbon composite material, the fairing protects satellites on their way to orbit. SpaceX is recovering fairing for reuse on future missions.
