LauncherOne
LauncherOne is an orbital launch vehicle under development by Virgin Galactic in the 2010s. It is an air launch to orbit rocket, designed to launch " smallsat" payloads of 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."
