SpaceDev
successfully completed its full duration hybrid
rocket motor test for SpaceShipOne, the final test under the current phase of
SpaceDev’s contract with Scaled Composites in Mojave, CA. SpaceDev is
competing to be the provider of rocket motors for SpaceShipOne.

SpaceDev has developed small and large hybrid rocket motors under
contracts with government agencies and private companies. Hybrid rocket
motors are non-explosive and inexpensive, using a solid hydrocarbon fuel, and
a liquid oxidizer to make the fuel burn. SpaceDev uses rubber or plastic for
fuel, and nitrous oxide for the oxidizer.

Under a separate contract, SpaceDev is designing a cluster of three
microsatellites to fly in formation and communicate over a wireless LAN in
space. SpaceDev was recently awarded a Department of Defense (DoD) contract
to begin designing a small, inexpensive, hybrid-based launch vehicle for
microsatellites. Under another DoD contract, SpaceDev is building a hybrid-
based small and agile orbital transfer and maneuvering vehicle for moving
small payloads from one orbit to another.
