NM22-416-017 (20 Sept. 1996) --- One of the first priorities of astronaut John E. Blaha, mission specialist for STS-79 and soon to be cosmonaut guest researcher for Mir-22, was to get his Sokol space suit pressure-checked for the move aboard Russia�s Mir Space Station. On flight day four, Blaha and his STS-79 crew mates aboard the Space Shuttle Atlantis docked with Mir. Here, seen soon after hatch opening, Blaha prepares for the needed suit tests.
