His technical assignments to date include: spacecraft communicator (CAPCOM) in Mission Control; flight software verification in the Shuttle Avionics Integration Laboratory (SAIL); coordinating flight crew equipment; evaluating extravehicular activity (EVA) equipment and techniques for the construction of Space Station; lead for the Payloads and Habitability Branch of the Astronaut Office. A veteran of three space flights, STS-57 in 1993, STS-68 in 1994 and STS-81 in 1997, Dr. Wisoff has logged over 754 hours in space. Dr. Wisoff is assigned as a mission specialist on STS-92, the third Space Shuttle mission to assemble the International Space Station. Launch is scheduled for late 2000.

SPACE FLIGHT EXPERIENCE: STS-57 Endeavour (June 21 to July 1, 1993) launched from and returned to land at the Kennedy Space Center, Florida. The primary objective of this flight was the retrieval of the European Retrievable Carrier satellite (EURECA) using the RMS. Additionally, this mission featured the first flight of Spacehab, a commercially-provided middeck augmentation module for the conduct of microgravity experiments. Spacehab carried 22 individual flight experiments in materials and life sciences research. During the mission Wisoff conducted a 5-hour, 50-minute spacewalk during which the EURECA communications antennas were manually positioned for latching, and various extravehicular activity tools and techniques were evaluated for use on future missions.

STS-68 (September 30 to October 11, 1994) was the Space Radar Lab-2 (SRL-2) mission. As part of NASA's Mission to Planet Earth, SRL-2 was the second flight of three advanced radars called SIR-C/X-SAR (Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar), and a carbon-monoxide pollution sensor, MAPS (Measurement of Air Pollution from Satellites). SIR-C/X-SAR and MAPS operated together in Endeavour's cargo bay to study Earth's surface and atmosphere, creating radar images of Earth's surface environment and mapping global production and transport of carbon monoxide pollution. Real-time crew observations of environmental conditions, along with over 14,000 photographs aided the science team in interpreting the SRL data. The SRL-2 mission was a highly successful test of technology intended for long-term environmental and geological monitoring of planet Earth. Following 183 orbits of the Earth in 269 hours and 46 minutes, the eleven-day mission ended with Space Shuttle Endeavour landing at Edwards Air Force Base, California.

STS-81 (January 12-22, 1997) was a ten-day mission, the fifth to dock with Russia's Space Station Mir, and the second to exchange U.S. astronauts. The mission also carried the Spacehab double module providing additional middeck locker space for secondary experiments. In five days of docked operations more than three tons of food, water, experiment equipment and samples were moved back and forth between the two spacecraft. Following 160 orbits of the Earth in 244 hours, 55 minutes, the STS-81 mission concluded with a landing on Kennedy Space Center's Runway 33 ending a 3.9 million mile journey.
