SpaceDev, a part of the "Space Systems Business" of Sierra Nevada Corporation, is prominent for its spaceflight and microsatellite work. It designed and built components for the hybrid rocket motors for Paul Allen's Tier One suborbital SpaceShipOne space program operated by Scaled Composites. It is also developing micro- and nano-satellites, a small expendable launch vehicle, the SpaceDev Streaker, and has designed a piloted suborbital and orbital spaceship of its own, the SpaceDev Dream Chaser, in collaboration with NASA.

SpaceDev is based near San Diego in Poway, California. Its objective is to make routine commercial spaceflight possible and to help open space for all of humanity.

Previously a publicly traded company (OTCBB:SPDV), on 20 October 2008 SpaceDev officials announced that the company would be acquired by Sierra Nevada Corporation, a privately owned company.
