The Space Shuttle orbiter Atlantis rolls from Orbiter Processing Facility
Bay 3 to the Vehicle Assembly Building April 20, 1995, atop the orbiter
transporter for mating to its external tank and solid rocket boosters
in preparation for the STS-71 mission. Atlantis docked with the Russian
Space Station Mir during the 11-day mission. Later, both Mir and STS-71
flight crew members conducted joint medical investigations in the Spacelab-Mir
module located in the orbiter's payload bay.
