Washington, DC Jan. 27, 1998 – NASA has selected Orbital Sciences Corp. of Dulles, Va. as the second U.S. maker of small satellites to win a multi-year contract under the new Rapid Spacecraft initiative project. The contract covers six of the firm's spacecraft designs.

The award, which

covers three years under the Indefinite Delivery/Indefinite Quantity

structure, pre-qualifies OSC satellites for mission selection under the

space agency's Rapid Spacecraft Development initiative.

Approved for use under the award are OSC's PicoStar, MicroStar, PegaStar,

LEOStar, and FUSE satellite bus designs. The StarBus system, which can

support small satellite flights to medium and geostationary orbits, was

also added to the pre-approved list Monday.

The OSC satellite designs join Ball Aerospace of Boulder, Colo. as elements

of the Rapid Spacecraft catalog. Late last year, NASA chose Ball to build

the first RS project, the ocean wind research satellite Quickscat, planned

for launch aboard a retired Air Force Titan II ballistic missile in

November 1998. In addition to OSC and Ball satellite designs, NASA has

selected Lockheed Martin Missiles and Space, Sunnyvale, Calif., Space

Systems L oral, Palo Alto, Calif., Spectrum Astro Gilbert, AZ., Swales

Aerospace Beltsville, MD., and TRW, Inc, of Redondo Beach, Calif. to

participate in the RSD initiative.
