NASA astronaut and Mir 24 crew member David Wolf, M.D., who was on the Russian Space Station Mir since late September 1997, greets his friend, Tammy Kruse, shortly after his return to Earth on Jan. 31. Dr. Wolf returned aboard the orbiter Endeavour with the rest of the STS-89 crew, including Commander Terrence Wilcutt; Pilot Joe Edwards Jr.; and Mission Specialists James Reilly, Ph.D.; Michael Anderson; Bonnie Dunbar, Ph.D.; and Salizhan Sharipov with the Russian Space Agency. STS-89 Mission Specialist Andrew Thomas, Ph.D., succeeded Dr. Wolf on Mir and is scheduled to remain on the Russian space station until the STS-91 Shuttle mission returns in June 1998. In addition to the docking and crew exchange, STS-89 included the transfer of science, logistical equipment and supplies between the two orbiting spacecrafts KSC-98pc261

The Space Shuttle program was the United States government's manned launch vehicle program from 1981 to 2011, administered by NASA and officially beginning in 1972. The Space Shuttle system—composed of an orbiter launched with two reusable solid rocket boosters and a disposable external fuel tank— carried up to eight astronauts and up to 50,000 lb (23,000 kg) of payload into low Earth orbit (LEO). When its mission was complete, the orbiter would re-enter the Earth's atmosphere and lands as a glider. Although the concept had been explored since the late 1960s, the program formally commenced in 1972 and was the focus of NASA's manned operations after the final Apollo and Skylab flights in the mid-1970s. It started with the launch of the first shuttle Columbia on April 12, 1981, on STS-1. and finished with its last mission, STS-135 flown by Atlantis, in July 2011.
