S76-E-5225 (28 March 1996) --- Astronaut Michael R. (Rich) Clifford, right, mission specialist, says his good-bye to cosmonaut Yury I. Onufrienko, Mir-21 mission commander. The Space Shuttle Atlantis was within hours of its separation from its link with Russia's Mir Space Station. Onufrienko's crew has grown by one member, as the STS-76 crew leaves Shannon W. Lucid onboard Mir for the first leg of an almost-five-month stay.
