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-6, known before launch as TDRS-F, 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 is based on a custom satellite bus which was used for all seven first generation TDRS satellites.

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. This system was designed to replace a pre-existing worldwide network of ground stations that had supported all of NASA's manned flight missions and unmanned satellites in low-Earth orbits. The primary system design goal was to increase the amount of time that these spacecraft were in communication with the ground and improve the amount of data that could be transferred. These TDRSS satellites are all designed and built to be launched to and function in geosynchronous orbit, 35,786 kilometres (22,236 mi) above the surface of the Earth.
The first seven TDRSS satellites were built by the TRW corporation. 

This version, acquired from the estate of a TRW employee, varies slightly from the more common TDRS-C patch. The "Flight" is in a sans font and there are multiple differences in the details and colors. 

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.

This version differs from another patch for this payload.

TDRS-4, known before launch as TDRS-D, is an American communications satellite which was operated by NASA as part of the Tracking and Data Relay Satellite System from 1989 until 2011. It was constructed by TRW, based on a custom satellite bus which was used for all seven of the first generation TDRS satellites

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.

 GeoLITE is an advanced technology demonstration satellite with a laser communications experiment and an operational UHF communications mission. The GeoLITE program also employs streamlined acquisition and design-to-cost methodologies to complete the satellite development, integration and launch. The satellite is based on a modular bus design with multi-mission capabilities.
The satellite was designed and built in 3 1/2 years using streamlined program methodologies by TRW Space & Electronics, Redondo Beach, a subsidiary of TRW, Inc. for the National Reconnaissance Office (NRO).

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.

Flight 1 was launched April 5, 1983 during STS-6 (Challenger).
TDRS-1 was shut down by NASA June 27, 2010.

ISEE-3 was renamed ICE (International Cometary Explorer) when, after
completing its original mission in 1982, it was gravitationally
manuvuered to intercept the comet P/Giacobini-Zinner. On
September 11, 1985, the veteran NASA spacecraft flew through the
tail of the comet.
