Cosmic Girl
Boeing 747 aircraft operated by Stratolaunch
Cosmic Girl is a Boeing 747-400 aircraft. After the bankruptcy (2023) of Virgin Orbit, the airplane was sold to Stratolaunch. It is used as part of the Roc launch platform.
It was bought by Virgin Galactic in 2015.
When a LauncherOne launches from Cosmic Girl at high altitude, then that rocket can put a small satellite up to 300 kg (660 lb) (see satellite) payload into orbit.
