Orbital flight test program extended



NASA has extended the date for completion of the first four space shuttle orbital flight tests to April 1982. The extension of the flight test program has made it necessary to reschedule the first operational flight of the Columbia (STS-5) from March 1 982 to September 1 982.

The decision to extend the flight test program and reschedule STS-5 is the result of several factors, the major one being the continuing engineering assessment and improvement of the thermal protection system.
