LauncherOne

LauncherOne is a two-stage orbital launch vehicle developed and flown by Virgin Orbit. It is an air-launched rocket, designed to carry smallsat payloads of up to 300 kg (660 lb) into Sun-synchronous orbit (SSO), following air launch from a carrier aircraft at high altitude. The rocket is carried to the upper atmosphere on a modified Boeing 747-400, named Cosmic Girl, and released over the Pacific Ocean. Initial work on the program was done by Virgin Galactic, another Virgin Group subsidiary, before a separate entity— Virgin Orbit—was formed in 2017 to complete development and operate the launch service provider business as a separate entity from the passenger-carrying Virgin Galactic business.
