STS-71 Atlantis (June 27 to July 7, 1995), was the first Space Shuttle mission to dock with the Russian Space Station Mir, and involved an exchange of crews. The Atlantis was modified to carry a docking system compatible with the Russian Mir Space Station. Dr. Dunbar served as MS-3 on this flight which also carried a Spacelab module in the payload bay in which the crew performed medical evaluations on the returning Mir crew. These evaluations included ascertaining the effects of weightlessness on the cardio/vascular system, the bone/muscle system, the immune system, and the cardio/pulmonary system. Mission duration was 9 days, 19 hours, 23 minutes and 8 seconds, traveling 4.1 million miles in 153 orbits of the earth.

STS-89 Endeavour (January 22-31, 1998), was the eighth Shuttle-Mir docking mission during which the crew transferred more than 9,000 pounds of scientific equipment, logistical hardware and water from Space Shuttle Endeavour to Mir. Dr. Dunbar was the Payload Commander, responsible for all payload activities including the conduct of 23 technology and science experiments. In the fifth and last exchange of a U.S. astronaut, STS-89 delivered Andy Thomas to Mir and returned with David Wolf. Mission duration was 8 days, 19 hours and 47 seconds.
