An STS-75 onboard photo of the Tethered Satellite System-1 Reflight (TSS-1R) atop its extended boom. The TSS-1R was a reflight of TSS-1, which was flown on the Space Shuttle in July/August, 1992. Building on the knowledge gained on the TSS-1 about tether dynamics, the TSS will circle the Earth at an altitude of 296 kilometers (184 miles), placing the tether system well within the rarefield, electrically charged layer of the atmosphere known as the ionosphere. The satellite was plarned to be deployed 20.7 kilometers (12.9 miles) above the Shuttle. The conducting tether, generating high voltage and electrical currents as it moves through the ionosphere cutting magnetic field lines, would allow scientists to examine the electrodynamics of a conducting tether system. In addition, the TSS would increase our understanding of physical processes in the near-Earth space environment, such as plasma waves and currents. The tether on the TSS broke as the Satellite was nearing the full extent of its 12.5 mile deployment from the Shuttle. The TSS was a cooperative development effort by the Italian Space Agency (ASI) and NASA, and was managed by scientists at the Marshall Space Flight Center.

The Space Shuttle Orbiter Columbia's (STS-75) mission came to a close as the orbiter touched down on Runway 33 of Kennedy Space Center's Shuttle Landing Facility on March 9, 1996. Off to the right is the Vehicle Assembly Building and the Shuttle Training Aircraft (STA). The Mate/Demate Device (MDM) is at left. This Marshall Space Flight Center managed mission lasted 15 days and 17-hours, during which time the seven member crew conducted microgravity research with the U.S. Microgravity Payload (USMP-3), which flew for the third time. The other primary payload was the Tethered Satellite System (TSS-1R),a reflight from an earlier mission, but the satellite was lost when the tether broke just short of its fully deployed length of nearly 13 miles.

STS075-711-024 (25 Feb. 1996) --- The Tethered Satellite System (TSS) is seen as it is reeled out during early stages of deployment operations. The crew deployed the TSS, which later broke free. The seven member crew was launched aboard the space shuttle Columbia on Feb. 22, 1996, and landed on March 9, 1996. Crewmembers were Andrew M. Allen, mission commander; Scott J. Horowitz, pilot; Franklin R. Chang-Diaz, payload commander; and Maurizio Cheli European Space Agency (ESA); Jeffrey A. Hoffman and Claude Nicollier, ESA, all mission specialists; along with payload specialist Umberto Guidoni of the Italian Space Agency (ASI).

STS075-701-087 (25 Feb. 1996) --- A medium close-up view, captured with a 70mm camera, shows the Tethered Satellite System (TSS) and part of its supportive boom device prior to deployment operations. On Feb. 25, 1996, the crew deployed the TSS, which later broke free. The seven member crew was launched aboard the space shuttle Columbia on Feb. 22, 1996, and landed on March 9, 1996. Crewmembers were Andrew M. Allen, mission commander; Scott J. Horowitz, pilot; Franklin R. Chang-Diaz, payload commander; and Maurizio Cheli, European Space Agency (ESA); Jeffrey A. Hoffman and Claude Nicollier, ESA, all mission specialists; along with payload specialist Umberto Guidoni of the Italian Space Agency (ASI).

KENNEDY SPACE CENTER, FLA. -- The Space Shuttle Columbia arrives at Launch Pad 39B following an approximate seven-hour journey from the Vehicle Assembly Building. Columbia is being prepared for a targeted Feb. 22 liftoff on Mission STS-75, which will feature a re-flight of the Tethered Satellite System (TSS-1R) and the third flight of the U.S. Microgravity Payload (USMP-3)

STS075-325-014 (25 Feb. 1996) --- The frayed end of the tether portion of the Tethered Satellite System (TSS) is seen at the end of the supportive boom. On February 25, 1996, the crew deployed the TSS, which later broke free. The seven member crew was launched aboard the Space Shuttle Columbia on February 22, 1996, and landed on March 9, 1996. Crewmembers were Andrew M. Allen, mission commander; Scott J. Horowitz, pilot; Franklin R. Chang-Diaz, payload commander; and Maurizio Cheli, European Space Agency (ESA); Jeffrey A. Hoffman and Claude Nicollier (ESA), all mission specialists; along with payload specialist Umberto Guidoni of the Italian Space Agency (ASI).

STS075-360-021 (22 Feb.- 9 March 1996) --- The loose tether forms a faint diagonal line in this scene recorded on a later fly-by. On Feb. 25, 1996, the crew deployed the Tethered Satellite System (TSS), which later broke free. The seven member crew was launched aboard the space shuttle Columbia on Feb. 22, 1996, and landed on March 9, 1996. Crew members were Andrew M. Allen, mission commander; Scott J.

The crew will deploy and work with the Tethered Satellite System (TSS-1R). Seated at center are astronauts Scott J. Horowitz (left), pilot; and Andrew M. Allen, commander. Astronaut Franklin R. Chang-Diaz (front right) is payload commander. In the rear are (left to right) European Space Agency (ESA) astronaut Maurizio Cheli, mission specialist; payload specialist Umberto Guidoni of the Italian Space Agency (ASI); Jeffrey A. Hoffman and ESA astronaut Claude Nicollier, mission specialists.

The Space Shuttle Columbia (STS-75) cleared the tower following an on-time liftoff from Launch Pad 39B. Visible at lower left is the white room on the orbiter access arm through which the flight crew entered the orbiter earlier. Columbia's mission lasted 14 days and included retesting of the Tethered Satellite System (TSS-1R) and the third flight of the United States Microgravity Payload (USMP-3), both of which are managed by scientist at Marshall Space Flight Center. Included in Columbia's flight crew were members of the European Space Agency (ESA) and the Italian Space Agency (ASI), Mission Specialists Maurizio Cheli, Claude Nicollier and Payload Specialist Umberto Guidoni, respectively.
