Workers in the Payload Changeout Room (PCR) at Launch Pad 39A are preparing to close the payload doors for flight on the Space Shuttle Atlantis, targeted for liftoff on Mission STS-79 around Sept. 12. The payloads in Atlantis' cargo bay will play key roles during the upcoming spaceflight, which will be highlighted by the fourth docking between the U.S. Shuttle and Russian Space Station Mir. Located in the aft (lowermost) area of the payload bay is the SPACEHAB Double Module, filled with supplies and other items slated for transfer to the Russian Space Station Mir as well as research equipment. The SPACEHAB is connected by tunnel to the Orbiter Docking System (ODS). This view looks directly at the top of the ODS and shows clearly the Androgynous Peripheral Docking System (APDS) that interfaces with the Docking Module on Mir to achieve a linkup.
