CAPE CANAVERAL, Fla. (Reuters) - Astronauts on board the shuttle Discovery tested landing systems on Thursday while flight directors considered the prospect the space freighter might have to touch down on Friday at a lightly equipped site in New Mexico.
NASA kept the shuttle in space an extra day to finish a job at the International Space Station. The delay cost it a spare day to wait out bad weather forecast for both the shuttle's prime landing site at the Kennedy Space Center in Florida and the backup runways at Edwards Air Force Base in California.
