Cosmic Girl (aircraft)

Cosmic Girl is a Boeing 747-400 aircraft. A former passenger airliner operated by Virgin Atlantic, it was purchased by Virgin Galactic in 2015 to be used as the first stage launch platform (or mothership) for the air launch stage of the smallsat orbital launch vehicle, the LauncherOne. In 2017, the aircraft was transferred to the orbital launch subsidiary, Virgin Orbit, and its livery updated to "Virgin Orbit" livery. LauncherOne attempted its first launch on 25 May 2020; the launch was a failure. First successful launch (second launch in total) took place 17 January 2021.
Airliner.
"Cosmic Girl" was assembled in 2001 at the Boeing Everett Factory. It was configured as a 44/32/310 B747-41R, c/n. 32745. The aircraft's first flight was on 29 September 2001, and it was delivered to Virgin Atlantic on 31 October 2001, where it was registered as G-VWOW.
On 3 November 2005, the aircraft was landing at Runway 27R at Heathrow Airport when a crosswind caused it to roll to the left, and the left-most (No. 1) engine struck the ground.
The plane was transferred to Virgin Galactic in 2015 and re-registered in the United States as N744VG.
"Cosmic Girl" is currently based at the Long Beach Airport.
Launch platform.
The jetliner was in-service with the airline until October 2015. The airliner, previously leased by Virgin Atlantic, was purchased outright by Virgin Group for Virgin Galactic, and registered as N744VG, in November 2015. A 747 was selected due to its carrying capacity. The acquisition of the 747 allowed the use of separate carrying aircraft for SpaceShipTwo and LauncherOne. With the spinoff of Virgin Orbit in 2017, "Cosmic Girl" was also transferred.
The air launch to orbit LauncherOne rocket was originally envisioned to operate from the smaller airplane WhiteKnightTwo (WK2) launch platform, used for the suborbital Tier 1b system of WK2 and SpaceShipTwo (SS2). However, as the size of LauncherOne expanded to better encompass the marketplace and acquire marketshare of small launches, the rocket outgrew WK2, leading to the evaluation of bigger launch aircraft, and the acquisition of "Cosmic Girl" for LauncherOne operations. The use of a larger airplane allows doubling of LauncherOne payload capacity to , though with the selection of a 747, ultimately, may be supported. 747s have previously been used to air launch other craft, including the Space Shuttle "Enterprise". The use of "Cosmic Girl" marks the first use of a 747 as a space launch platform.
The LauncherOne attachment pylon is situated on the left wing, where on a normal 747, the fifth engine attachment point is located for ferrying engines. This point is located between the fuselage and the left inboard engine. LauncherOne would be dropped from "Cosmic Girl" at a height of . The maximum payload limit for LauncherOne operations on "Cosmic Girl" is .
Making its first flight, on 25 May 2020, a privately-funded air-launched rocket, LauncherOne, developed and built by Virgin Orbit failed to reach space after release from "Cosmic Girl", over the Pacific Ocean. The second launch on 17 January 2021, successfully delivered 10 CubeSats to low Earth orbit (LEO).
