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. 

TDRS-1, known before launch as TDRS-A, is an American communications satellite which is operated by NASA as part of the Tracking and Data Relay Satellite System. It was constructed by TRW and launched by Space Shuttle Challenger on its maiden flight, STS-6.

This patch is a modern reproduction of the original STS-6 TDRS-1 patch.

STS-6 was a NASA Space Shuttle mission conducted using Space Shuttle Challenger, carrying the first Tracking and Data Relay Satellite, TDRS-1, into orbit. Launched on 4 April 1983, STS-6 was the sixth shuttle mission and the first of the ten missions flown by Challenger. The mission took off from Kennedy Space Center's launch pad 39A, and landed at Edwards Air Force Base on 9 April. This was the first Space Shuttle mission during which a spacewalk was conducted, and the first in which the Extravehicular Mobility Unit (EMU) was used.

This version differs slightly from the regular Lion Brothers STS-6 patch and is much more scarce.

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.

The names of the astronauts are larger than the A-B Emblem version and the IUS is stitched narrower.

The Boeing-built Inertial Upper Stage, or IUS, is a two-stage payload delivery vehicle that is compatible with both the Space Shuttle and the Titan IV launch vehicles. Since first launch in 1982, the IUS has delivered payloads to a wide range of earth orbits.

TDRS-B was an American communications satellite, which was to have formed part of the Tracking and Data Relay Satellite System. It was destroyed when the Space Shuttle Challenger disintegrated 73 seconds after launch.
