SpaceX's payload fairing, used on both Falcon Heavy and Falcon 9, is a composite structure fabricated in-house by SpaceX that protects satellites during delivery to low-Earth orbit (LEO), geosynchronous transfer orbit (GTO), and beyond. The fairing is 13.1 meters (43 feet) high and 5.2 meters (17 feet) wide. It consists of an aluminum honeycomb core with carbon-fiber face sheets fabricated in two half-shells.
After first and second stage separation and prior to second stage cutoff, the pneumatic system along the vertical seam push open for satellite deployment. The satellite is then delivered the rest of the way to orbit by the second stage, and released.
