TDRS-B - STS-51E - IUS - Woven Version

Mission objective was to deploy the TDRS-B communication satellite, cancelled due to IUS failure. Most of the crew would be reassigned to STS-51-D which flew in April 1985 (except for Patrick Baudry, who was re-assigned to STS-51-G which flew in June 1985).

This version of the TDRS-B patch is not a silk patch but was woven. Acquired from the estate of a TRW employee.

STS-51E - A-B Emblem

Mission objective was to deploy the TDRS-B communication satellite, cancelled due to IUS failure. Most of the crew would be reassigned to STS-51-D which flew in April 1985 (except for Patrick Baudry, who was re-assigned to STS-51-G which flew in June 1985).

 

The A-B Emblem patch has a cut edge around the body and a sew-on tab. There are two colors of twill background, dark and light bluie. There are also two colors of sew on tabs, a dark blue and light blue as seen in the photos:

 

  • Type 1, Dark blue main body with dark blue tab. (Hard to find).
  • Type 2, Dark blue main body with a light blue tab. (Very Rare). 
  • Type 2A, Light blue main body with a dark blue tab. (Extremely Rare).
  • Type 3, Light blue main body with a light blue tab. (Hard to find), but the most common of the 4 patches. 

The photo on this page are the "Type 1" issue.

STS-51L - TDRS-B - TRW

TDRS-B was launched in the payload bay of Challenger, attached to an Inertial Upper Stage (IUS). It was to have been deployed from the Shuttle in low Earth orbit. The IUS would have then performed two burns to raise the satellite into a geosynchronous orbit. On the previous TDRS launch, TDRS-1, the IUS second stage motor malfunctioned following the first stage burn, resulting in a loss of control, and delivery of the satellite into an incorrect orbit.

TDRS-B was originally scheduled for launch on STS-12 in March 1984, however it was delayed and the flight cancelled following the IUS failure on TDRS-1. It was later re-manifested on STS-51E, however this too was cancelled due to concerns over the reliability of the IUS. It was eventually assigned to STS-51L, which was to also carry the SPARTAN-Halley astronomy satellite.

STS-51L launched with TDRS-B at 16:38 GMT on 28 January 1986. The Shuttle disintegrated 73 seconds after launch due to an o-ring failure in one of the Solid Rocket Boosters, killing the seven astronauts aboard.
 

Note that a dark bordered variation also exists.

TDRS-B - STS-51L

A Tracking and Data Relay Satellite (TDRS) is a type of communications satellite that forms part of the Tracking and Data Relay Satellite System (TDRSS) used by NASA and other United States government agencies for communications to and from independent "User Platforms" such as satellites, balloons, aircraft, and the International Space Station.

The second Tracking and Data Relay Satellite was destroyed along with Challenger shortly after launch during the STS-51-L mission in January 1986. The next five TRW-built TDRSS satellites were successfully launched on other Space Shuttles.

Tracking and Data Relay Satellite (TDRS-B)

The Tracking and Data Relay Satellite (TDRS) system represents a new era in tracking Earth-orbiting spacecraft, including the Space Shuttle, and transmitting their data back to Earth. The TDRS concept was conceived following early 1970s studies which showed that a system of orbiting telecommunications satellites, operated from a single ground terminal link, could more effectively support Space Shuttle, scientific and other NASA mission requirements than the nearly 25-year-old tracking and communications network of ground stations located worldwide. Flight 2 was destroyed on STS-51L (Challenger).
