NASA TO DELAY SHUTTLE LAUNCH FOR TWO DAYS
CAPE CANAVERAL, FLA. — Engineers this week swapped a faulty electronic part on the space shuttle Discovery and NASA expressed optimism it could hold the latest delay to two days and launch Discovery on Monday, March 13. But space agency spokesman Dick Young said that a firm date could not be set until after the replacement unit was thoroughly checked out.
The launch, which had been set for Saturday after three earlier postponements, received its latest setback this week. A prelaunch test disclosed the failure of a vital system that commands separation of the booster rockets and the external fuel tank from the shuttle in flight.
