Pressure Mounting on Orbital For December Run to Station

摘要

Orbital Sciences Corp., which is preparing to send its Cygnus cargo freighter to the international space station (ISS) for the first time later this month, was put on notice Sept. 4 by a NASA official who said the Dulles, Va., company could be needed for another cargo run as soon as December because Space Exploration Technologies Corp. (SpaceX) - the agency's other cargo-delivery contractor - likely will not be ready to fly.
