Mission overview

The start of the mission was scheduled on August 8, 1989. Thus the space shuttle Columbia since the Challenger disaster began its first flight in January 1986. STS -28 was the fourth mission on behalf of the U.S. Department of Defense and its purpose, therefore, was subject to confidentiality.

During the flight, two military satellites were exposed. One could have been a communications satellite as part of the Satellite Data System (SDS ).

The landing took place on August 13, 1989 at Edwards Air Force Base in California. During the re-entry into the atmosphere unexpectedly high temperatures were measured on the heat shield. Reason for this was probably protruding filler.

The orbiter was launched eight days later transported from the Shuttle Carrier Aircraft to the launch site in Florida.
