SPACE FLIGHT EXPERIENCE: The STS-66 Atmospheric Laboratory for Applications and Science-3 (ATLAS-3) mission was launched from Kennedy Space Center, Florida, on November 3, 1994, and returned to land at Edwards Air Force Base, California, on November 14, 1994. ATLAS-3 was part of an on-going program to determine the earth's energy balance and atmospheric change over an 11-year solar cycle, particularly with respect to humanity’s impact on global-ozone distribution. Dr. Parazynski had responsibility for a number of on-orbit activities including operation of the ATLAS experiments and Spacelab Pallet, as well as several secondary experiments in the crew cabin. He and his crewmates also successfully evaluated the Interlimb Resistance Device, a free-floating exercise he developed to prevent musculoskeletal atrophy in microgravity. The Space Shuttle Atlantis circled the earth 175 times and traveled over 4.5 million miles during its 262-hour and 34-minute flight. STS-86 Atlantis (September 25 to October 6, 1997) was the seventh mission to rendezvous and dock with the Russian Space Station Mir. Highlights of the mission included the exchange of U.S. crewmembers Mike Foale and David Wolf, the transfer of 10,400 pounds of science and logistics, and the first Shuttle-based joint American-Russian spacewalk. Dr. Parazynski served as the flight engineer (MS2) during the flight, and was also the navigator during the Mir rendezvous. Dr. Parazynski (EV1) and Russian cosmonaut Vladimir Titov performed a 5 hour, 1 minute spacewalk during which they retrieved four experiment packages first deployed during the STS-76 Shuttle-Mir docking mission. They also deployed the Spektr Solar Array Cap, which was designed to be used in a future Mir spacewalk to seal a leak in the Spektr module’s damaged hull. Other objectives of EVA included the evaluation of common EVA tools to be used by astronauts wearing either Russian or American-made spacesuits, and a systems flight test of the Simplified Aid for EVA Rescue (SAFER). The Space Shuttle Atlantis circled the earth 169 times and traveled over 4.2 million miles during its 259-hour and 21-minute flight, landing at the Kennedy Space Center. STS-95 Discovery (October 29 to November 7, 1998) was a 9-day mission during which the crew supported a variety of research payloads, including deployment of the Spartan solar-observing spacecraft and the testing of the Hubble Space Telescope Orbital Systems Test Platform. The crew also conducted investigations on the correlation between space flight and the aging process. Dr. Parazynski was the flight engineer (MS2) for the mission, as well as the navigator for the Spartan spacecraft rendezvous. During the flight, he also operated the Shuttle’s robotic arm in support of the testing of several space-vision systems being considered for ISS assembly. In addition, he was responsible for monitoring several life sciences investigations, including those involving crewmate Senator John Glenn. The mission was accomplished in 134 earth orbits, traveling 3.6 million miles in 213-hours and 44-minutes. STS-100 Endeavour (April 19 to May 1, 2001) was the 9th mission to the International Space Station (ISS) Alpha during which the crew successfully delivered and installed the Space Station "Canadarm2" robotic arm, to be used for all future Space Station assembly and maintenance tasks. Dr. Parazynski conducted two spacewalks with Canadian colleague Chris Hadfield to assemble and power the next generation robotic arm. Additionally, the pair installed a new UHF radio antenna for space-to-space communications during Space Shuttle rendezvous and ISS extravehicular activity. A critical on-orbit spare, a direct current switching unit, was also transferred to Alpha during the 14 hours and 50 minutes of EVA work. Also during the flight, Dr. Parazynski operated Endeavour's robotic arm to install, and later remove, the Italian-built "Raffaello" Multi-Purpose Logistics Module. Traveling 4.9 million miles in 283-hours and 30-minutes, the mission was accomplished in 186 earth orbits.
