### Spaceflight experience

STS-34 Atlantis (October 18–23, 1989) launched from the Kennedy Space Center in Florida, and landed at Edwards Air Force Base in California. During the mission, the crew deployed the Galileo probe to explore Jupiter, operated the Shuttle Solar Backscatter Ultraviolet Instrument (SSBUV) to map atmospheric ozone, conducted several medical experiments, and numerous scientific experiments. Mission objectives were accomplished in 79 orbits of the Earth, traveling 1.8 million miles in 119 hours and 41 minutes.
STS-50 Columbia (June 25, 1992 – July 9, 1992) launched and landed at the Kennedy Space Center in Florida. STS-50 was the first flight of the United States Microgravity Laboratory and the first Extended Duration Orbiter flight. Over a two-week period, the crew conducted scientific experiments involving crystal growth, fluid physics, fluid dynamics, biological science, and combustion science. Mission objectives were accomplished in 221 orbits of the Earth, traveling 5.7 million miles in 331 hours 30 seconds and 4 minutes in space.
STS-71 Atlantis (June 27 – July 7, 1995) launched from the Kennedy Space Center with a seven-member crew and returned there with an eight-member crew. STS-71 was the first Space Shuttle mission to dock with the Russian Space Station Mir, and involved an exchange of crews. The Atlantis Space Shuttle was modified to carry a docking system compatible with the Russian Mir Space Station. It also carried a Spacelab module in the payload bay in which the crew performed various life sciences experiments and data collections. Mission accomplished in 153 orbits of the Earth, traveling 4.1 million miles in 235 hours and 23 minutes.
