S76-E-5146 (24 March 1996) --- Continuing an in-space tradition, astronaut Kevin P. Chilton (right), STS-76 mission commander, shakes hands with cosmonaut Yury Onufrienko, Mir-21 commander, in the tunnel connecting the Space Shuttle Atlantis and Russia's Mir Space Station. A short time earlier two crews successfully pulled off the third hard-docking of their respective spacecraft. In the background is cosmonaut Yury V. Usachev, Mir-21 flight engineer. The image was recorded with a 35mm Electronic Still Camera (ESC) and downlinked at a later time to ground controllers in Houston, Texas.
