KENNEDY SPACE CENTER, FLA. -- The Space Station Processing Facility is filled with hardware, components for the International Space Station. Lined up (left to right) 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.

KENNEDY SPACE CENTER, FLA. -- The International Space Station's (ISS) Unity node, with Pressurized Mating Adapter (PMA)-2 attached, awaits further processing in the Space Station Processing Facility (SSPF). The Unity node is the first element of the ISS to be manufactured in the United States and is currently scheduled to lift off aboard the Space Shuttle Endeavour on STS-88 later this year. Unity has two PMAs attached to it now that this mate is completed. PMAs are conical docking adapters which will allow the docking systems used by the Space Shuttle and by Russian modules to attach to the node's hatches and berthing mechanisms. Once in orbit, Unity, which has six hatches, will be mated with the already orbiting Control Module and will eventually provide attachment points for the U.S. laboratory module; Node 3; an early exterior framework or truss for the station; an airlock; and a multi-windowed cupola. The Control Module, or Functional Cargo Block, is a U.S.-funded and Russian-built component that will be launched aboard a Russian rocket from Kazakstan

KENNEDY SPACE CENTER, FLA. -- In the Space Station Processing Facility, STS-88 Mission Specialists Sergei Krikalev, a Russian cosmonaut, and Jerry L. Ross check out equipment on the Unity connecting module, primary payload on the mission. The STS-88 crew members are participating in a Crew Equipment Interface Test (CEIT), familiarizing themselves with the orbiter's midbody and crew compartments. Scheduled for launch on Dec. 3, 1998, STS-88 will be the first Space Shuttle launch for the International Space Station. The Unity connecting module will be mated to the Russian-built Zarya control module, already on orbit after a November launch. Unity will have two Pressurized Mating Adapters (PMAs) attached and 1 stowage rack installed inside. PMA-1 will connect U.S. and Russian elements; PMA-2 will provide a Shuttle docking location. Eventually, Unity's six ports will provide connecting points for the Z1 truss exterior framework, U.S. lab, airlock, cupola, Node 3, and the Multi-Purpose Logistics Module, as well as the control module. Zarya is a self-supporting active vehicle, providing propulsive control capability and power through the early assembly stages. It provides fuel storage capability and a rendezvous and docking capability to the Service Module

In the Space Station Processing Facility, the Unity connecting module, part of the International Space Station, is shown with Pressurized Mating Adapters 1 (left) and 2 (right) attached. Unity is scheduled to undergo testing of the common berthing mechanism to which other space station elements will dock. Unity is the primary payload on mission STS-88, targeted to launch Dec. 3, 1998. Other testing includes the Pad Demonstration Test to verify the compatibility of the module with the Space Shuttle as well as the ability of the astronauts to send and receive commands to Unity from the flight deck of the orbiter. Unity is expected to be ready for installation into the payload canister on Oct. 25, and transported to Launch Pad 39-A on Oct. 27. The Unity will be mated to the Russian-built Zarya control module which should already be in orbit at that time

STS-92 Pilot Pamela Ann Melroy is happy to arrive at the KSC Shuttle Landing Facility after a flight from Houston. She and the rest of the crew are at KSC to take part in Terminal Countdown Demonstration Test activities, which include emergency egress training from the orbiter and pad, and a simulated countdown. The fifth mission to the International Space Station, STS-92 will carry the Integrated Truss Structure Z1, the first of the planned 10 trusses on the Space Station, and the third Pressurized Mating Adapter. The Z1 will allow the first U.S. solar arrays on a future flight to be temporarily installed on Unity for early power. PMA-3 will provide a Shuttle docking port for the solar array installation on the sixth ISS flight and Lab installation on the seventh ISS flight. STS-92 is scheduled to launch Oct. 5 from launch Pad 39A. It will be the 100th flight in the Shuttle program

KENNEDY SPACE CENTER, FLA. -- In the Space Station Processing Facility, STS-92 Pilot Pamela A. Melroy gets a close look at the Integrated Truss Structure Z1 that will fly on the mission, the fifth U.S. flight in the construction of the International Space Station. Other crew members are Commander Brian Duffy, and Mission Specialists Koichi Wakata, Leroy Chaio, Peter J.K. Wisoff, Michael E. Lopez-Alegria, and William S. McArthur Jr. Wakata is with the National Space Development Agency of Japan. The Z1 is an early exterior framework to allow the first U.S. solar arrays on a future flight to be temporarily installed on Unity for early power. Another part of the payload is a pressurized mating adapter, PMA-3, to provide a Shuttle docking port for solar array installation on the sixth ISS flight and Lab installation on the seventh ISS flight. Launch of STS-92 is scheduled for Sept. 21, 2000
