[edit] Mission highlights

Fourth mission dedicated to United States Department of Defense, and first flight of Columbia since mission STS-61-C. Due to the nature of this mission, details are classified. Believed to have deployed two satellites, possibly including one second-generation Satellite Data System relay.

It has been reported that STS-28 also deployed an Advanced KH-11 photo-reconnaissance satellite that used an all-digital imaging system to return pictures. The satellite was placed into a low earth orbit with a high-inclination to the equator to allow coverage of most of the Earth's surface. The KH-11 series is a digital imaging photo- reconnaissance satellite with both visual and infrared sensors.

The pioneering Space Shuttle Orbiter Columbia (OV-102), the first operational reusable spaceship in NASA's fleet, lifted off from Pad 39B, Launch Complex 39, KSC, on 8 August 1989. Liftoff time was 8:37 a.m. EDT. It was the 30th flight of the Space Shuttle, and the first flight of the refurbished Columbia since the 61-C mission on 12 January 1986. Landing was at Edwards AFB, CA, at 9:37 p.m. EDT. The mission lasted for 5 days and 1 hour.

During the flight, the crew shut down a thruster in the reaction control system (RCS) because of indications of a leak. Also, an RCS heater malfunctioned.

Post-flight analysis of STS-28 discovered unusual heating of the thermal protection system (TPS) during re-entry. A detailed report ([1] identified protruding gap filler as the likely cause. This filler material is the same material which was removed during a spacewalk on the STS-114 Return to Flight mission in 2005.
