Members of the STS-92 crew look over the payload (left) in Space Shuttle Discovery’s payload bay. Left to right, in masks, are Mission Specialists Leroy Chiao, Peter J.K. “Jeff” Wisoff and William S. McArthur Jr. They and the other crew members Commander Brian Duffy, Pilot Pamela Ann Melroy and Mission Specialists Koichi Wakata of Japan, and Michael E. Lopez-Alegria are preparing for launch on Oct. 5, 2000. The mission is the fifth flight for the construction of the International Space Station. The payload includes the Integrated Truss Structure Z-1 and the third Pressurized Mating Adapter. During the 11-day mission, four extravehicular activities (EVAs), or space walks, are planned KSC-00pp1472

KENNEDY SPACE CENTER, Fla. -- As the sky grows lighter, , the payload canister (left) with the Integrated Truss Structure Z1 inside is slowly lifted up the side of the Rotating Service Structure to the Payload Changeout Room. There the Z1 truss will be removed and later transferred to Space Shuttle Discovery’s payload bay. The Z1 truss is the first of 10 that will become the backbone of the International Space Station, eventually stretching the length of a football field. Along with its companion payload, the third Pressurized Mating Adapter, the Z1 is scheduled to be launched aboard Discovery Oct. 5 at 9:38 p.m. EDT KSC00pp1355

KENNEDY SPACE CENTER, FLA. -- At Launch Pad 39B the payload canister, with the Multi-Purpose Logistics Module Leonardo inside, nears the payload changeout room on the Rotating Service Structure. Umbilical hoses, maintaining a controlled environment for the cargo, are still attached to the lower end of the canister. At the PCR, the payload ground-handling mechanism (PGHM) will be used to transfer Leonardo out of the canister and then into Space Shuttle Discovery’s payload bay. One of Italy’s major contributions to the International Space Station program, Leonardo is a reusable logistics carrier. It is the primary delivery system used to resupply and return Station cargo requiring a pressurized environment. Leonardo is the primary payload on mission STS-102 and will deliver up to 10 tons of laboratory racks filled with equipment, experiments and supplies for outfitting the newly installed U.S. Laboratory Destiny.

CAPE CANAVERAL, Fla. – The sun sets behind Launch Pad 39A at NASA's Kennedy Space Center where the payload canister with the Japanese Experiment Module - Pressurized Module and the Japanese Remote Manipulator System, or RMS, inside awaits cargo transfer to the payload changeout room above. The changeout room is the enclosed, environmentally controlled portion of the service structure that supports cargo delivery to the pad and subsequent vertical installation into an orbiter's payload bay. From the payload changeout room, the pressurized module and RMS then will be transferred into space shuttle Discovery’s payload bay. Launch is targeted for May 31.

CAPE CANAVERAL, Fla. -- Positioned on its 12-wheeled, 24-tire transporter, the payload canister with the STS-124 mission payload, Japanese Experiment Module - Pressurized Module and the Japanese Remote Manipulator System, or RMS, inside, approaches the ramp to Launch Pad 39A at NASA's Kennedy Space Center. The transporter is 65 feet long and 23 feet wide. The transporter’s wheels are independently steerable, permitting it to move forward, backward, sideways or diagonally and to turn on its own axis like a carousel. It is equipped with pneumatic-actuated braking and hydrostat¬ic leveling and drive systems. It is steered from a two-seat operator cab mounted at one end. From the payload changeout room, the pressurized module and RMS will be transferred into space shuttle Discovery’s payload bay. Launch is targeted for May 31.

CAPE CANAVERAL, Fla. – In the Orbiter Processing Facility’s bay 3, the orbiter boom sensor system is lifted by a crane for installation in space shuttle Discovery’s payload bay for mission STS-128. The 50-foot-long boom attaches to the shuttle arm and provides equipment to inspect the shuttle's heat shield while in space. It contains an intensified television camera (ITVC) and a laser dynamic range imager, which are mounted on a pan and tilt unit, and a laser camera system (LCS) mounted on a stationary bracket. The STS-128 flight will carry science and storage racks to the International Space Station on space shuttle Discovery. Launch of Discovery is targeted for Aug. 6.

CAPE CANAVERAL, Fla. – In Orbiter Processing Facility-1 at NASA's Kennedy Space Center in Florida, space shuttle Discovery’s payload bay is glimpsed for the final time as its doors swing shut with the aid of yellow-painted strongbacks, hardware used to support and operate the doors when the shuttle is not in space. Discovery's doors are being closed for the final time during Space Shuttle Program transition and retirement activities. Following the door closure, the vehicle will be powered down for the last time. Discovery is being prepared for public display at the Smithsonian’s National Air and Space Museum Steven F.
