POWAY, Calif. (Aug. 13)—SpaceDev Inc. recently completed a successful full duration test of its hybrid rocket motor for SpaceShipOne, the final test under the company's contract with the craft's designer. The firm's hybrid motors use rubber or plastic for fuel and nitrous oxide for the oxidizer. SpaceDev is competing to be the rocket motor provider for SpaceShipOne. Scaled Composites of Mojave, Calif., has been working for two years on SpaceShipOne, a manned space program with the goal of affordable suborbital space flight.
