Astronaut Gibson and Comonaut Dezhurov shake hands

STS071-118-004 (29 June 1995) --- Astronaut Robert L. Gibson, STS-71 commander, shakes the hand of cosmonaut Vladimir N. Dezhurov, Mir-18 commander. The historic handshake took place two and half weeks prior to the 20th anniversary of a similar in-space greeting between cosmonauts and astronauts participating in the Apollo-Soyuz Test Project (ASTP). On July 17, 1975, astronaut Thomas P. Stafford, NASA's ASTP commander, greeted his counterpart, Aleksey A. Leonov in a docking tunnel linking the Soyuz and Apollo spacecraft.
