Re-Flight of the Deployable Retrievable Booms

The Tethered Satellite System (TSS), a scientific payload which was flown on STS-46 and again on STS-75, included two satellite-mounted Deployable Retrievable Booms (DRB's). The system was launched aboard the Space Shuttle Atlantis in July 1992. However, because of the problems which occurred at the original attempted deployment of the Tethered Satellite, the DRBs were never operated on-orbit during the STS-46 mission. In postflight functional tests, both DRB's failed to relatch properly. This paper discusses the troubleshooting of the anomalies, design changes, and DRB operational constraints incorporated for the STS-75 mission
