Abstract:

The Long Duration Exposure Facility LDEF was retrieved after spending 69 months in low Earth orbit LEO. LDEF carried a remarkable variety of mechanical, electrical, thermal, and optical systems, subsystems, and components. The Systems Special Investigation Group Systems SIG was formed to investigate the effects of the long term exposure to LEO on systems related hardware and to coordinate and collate all systems analysis of LDEF hardware. This report discusses the status of the LDEF Systems SIG investigation through the end of 1991.
