The floor of the Space Station Processing Facility is filled with racks and hardware for testing the various components of the International Space Station (ISS). The large module in the center of the floor (top) is the U.S. Lab, Destiny. Expected to be a major feature in future research, Destiny will provide facilities for biotechnology, fluid physics, combustion, and life sciences research. It is scheduled to be launched on mission STS-98 (no date determined yet for launch). At top left are the Multi-Purpose Logistics Modules Raffaello and Leonardo and the Pressurized Mating Adapter-3 (PMA-3). Italy's major contributions to the ISS program, Raffaello and Leonardo are reusable logistics carriers to resupply and return Station cargo requiring a pressurized environment. They are slated as payloads on missions STS-102 and STS-100, respectively. Dates have not yet been determined for the two missions. The PMA-3, once launched, will be mated to Node 1, a connecting passageway to the living and working areas of the Space Station. The primary purpose of PMA-3 is to serve as a Shuttle docking port through which crew members and equipment will transfer to the Space Station during later assembly missions. PMA-3 is scheduled as payload on mission STS-92, whose date for launch is not yet determined
