The STS-71 mission payload is in its final flight configuration after
integration into the payload bay of the Space Shuttle orbiter Atlantis
and prior to payload bay door closing and rollover of the spaceplane
from Orbiter Processing Facility Bay 3 to the Vehicle Assembly Building.
In the foreground is the Orbiter Docking System (ODS) that is topped
with the red Russian-built Androgynous Peripheral Docking System (APDS).
During the 11-day mission, the APDS will lock together with a similar
system on the Russian Mir Space Station so that the two spacecraft can
remain docked together for four days. The ODS features an airlock that
will provide access to and from both the Mir and orbiter for the U.S.
and Russian flight crews. A Spacelab transfer tunnel runs from the ODS
to the Spacelab-Mir module, where joint U.S. medical experiments will
be conducted during the 11-day spaceflight.
