LauncherOne

LauncherOne is an orbital launch vehicle under development by Virgin Orbit in the 2010s. It is an air launch to orbit rocket, designed to launch "smallsat" payloads of 200 kilograms (440 lb) into Sun-synchronous orbit, following air launch from a carrier aircraft at high altitude. Launches are projected to begin in Q4 2016.

Several commercial customers had contracted for launches by 2012, including GeoOptics, Skybox Imaging, Spaceflight Services, and Planetary Resources. Both Surrey Satellite Technology and Sierra Nevada Space Systems are developing satellite buses "optimized to the design of LauncherOne."

Virgin Galactic began working on the LauncherOne concept in 2007, and the technical specifications were first described in some detail in late 2009. The LauncherOne configuration was proposed to be an expendable, two-stage, liquid-fueled rocket air-launched from a White Knight Two carrier aircraft. This would make it a similar configuration to that used by Orbital Sciences' Pegasus, or a smaller version of the StratoLaunch air-launched rocket system.
