| Full Description |
The free-flying Tracking and Data Relay Satellite-E (TDRS-E), still attached to an Inertial Upper Stage (IUS), was photographed by one of the crewmembers during the STS-43 mission. The TDRS-E was boosted by the IUS into geosynchronous orbit and positioned to remain stationary 22,400 miles above the Pacific Ocean southwest of Hawaii. The TDRS system provides almost uninterrupted communications with Earth-orbiting Shuttles and satellites, and had replaced the intermittent coverage provided by globe-encircling ground tracking stations used during the early space program. The TDRS can transmit and receive data, and track a user spacecraft in a low Earth orbit. The IUS is an unmarned transportation system designed to ferry payloads from low Earth orbit to higher orbits that are unattainable by the Shuttle. The Space Shuttle Orbiter Atlantis for the STS-43 mission was launched on August 2, 1991. |

| Full Description |
The primary payload of the STS-43 mission, Tracking and Data Relay Satellite-E (TDRS-E) attached to an Inertial Upper Stage (IUS) was photographed at the moment of its release from the cargo bay of the Space Shuttle Orbiter Atlantis. The TDRS-E was boosted by the IUS into geosynchronous orbit and positioned to remain stationary 22,400 miles above the Pacific Ocean southwest of Hawaii. The TDRS system provides almost uninterrupted communications with Earth-orbiting Shuttles and satellites, and had replaced the intermittent coverage provided by globe-encircling ground tracking stations used during the early space program.

STS-43 TDRS-E and IUS over the Pacific Ocean after deployment from OV-104's PLB |
| Description |
The Tracking and Data Relay Satellite E (TDRS-E) and Inertial Upper Stage (IUS) combination is silhouetted over the cloud-covered Pacific Ocean shortly after deployment from Atlantis', Orbiter Vehicle (OV) 104's, payload bay (PLB) during the STS-43 mission. OV-104 leaves TDRS-E/IUS behind as it begins its separation maneuvers. |

STS-43 TDRS-E and IUS over the Pacific Ocean after deployment from OV-104's PLB |
| Description |
The Inertial Upper Stage (IUS) interstage and first stage solid rocket motor nozzle are backdropped against an interesting cloud pattern over the Pacific Ocean shortly after deployment from Atlantis', Orbiter Vehicle (OV) 104's, payload bay (PLB) during the STS-43 mission. The Tracking and Data Relay Satellite E's (TDRS-E's) stowed solar array panels are barely visible on top of the IUS. OV-104 leaves TDRS-E/IUS behind as it begins its separation maneuvers. |

STS-43 TDRS-E / IUS is deployed from OV-104's payload bay (PLB) |
| Description |
During STS-43, the Tracking and Data Relay Satellite E (TDRS-E), atop the inertial upper stage (IUS) and raised to a 58-degree deployment position in the airborne support equipment (ASE) aft frame tilt actuator (AFTA) table with the forward frame ASE latch actuator released and umbilical cables separated, is released by a spring-loaded ejection system and a Super*zip ordnance separation device from Atlantis', Orbiter Vehicle (OV) 104's, payload bay (PLB). TDRS-E/IUS combination rises above OV-104's PLB at approximately 0.4 foot per second. The scene is highlighted against the Earth's limb and the cloud-covered Pacific Ocean below. In the foreground on the port side and mounted on a getaway special (GAS) adapter beam are (forward to aft) the two Shuttle Solar Backscatter Ultraviolet (SSBUV) GAS canisters (one with motorized door assembly (MDA)) and the Tank Pressure Control Experiment (TPCE) GAS canister. Along the starboard sill longeron is the Space Station Heat Pipe Advanced Radiator |

STS-43 TDRS-E / IUS is deployed from OV-104's payload bay (PLB) |
| Description |
During STS-43, the Tracking and Data Relay Satellite E (TDRS-E), atop the inertial upper stage (IUS), rises above Atlantis', Orbiter Vehicle (OV) 104's, payload bay (PLB) at the rate of approximately 0.4 foot per second. The IUS is highlighted against the Earth's limb and the cloud-covered Pacific Ocean. Left behind in the PLB are the airborne support equipment (ASE) forward frame, the ASE umbilical, and the ASE aft frame tilt actuator (AFTA) table (at 58-degree deployment position). TDRS-E/IUS was released by a spring-loaded ejection system and a Super*zip ordnance separation device on Orbit 5. In the foreground on the port side and mounted on a getaway special (GAS) adapter beam are (forward to aft) the two Shuttle Solar Backscatter Ultraviolet (SSBUV) GAS canisters (one with motorized door assembly (MDA)) and the Tank Pressure Control Experiment (TPCE) GAS canister. Along the starboard sill longeron is the Space Station Heat Pipe Advanced Radiator Element II (SHARE-II). |
