MOJAVE - A Virginia company and Burt Rutan's Scaled Composites dropped dummy rocket boosters from an aircraft in a test of a new launch method for passenger-carrying spacecraft. Liquid-propellant rockets are more complex, requiring pumps and other systems, but NASA has been studying their use for the shuttle boosters in part because they would allow the motors to be throttled down or even stopped and restarted if necessary. The two compressors for the Spanish plants are single-stage fuel gas boosters to be used in two 400 megawatt power plants. |
