KENNEDY SPACE CENTER, FLA. -- The payload canister transporter and canister approach the rotating service structure (RSS) on Launch Pad 39B. Inside the canister are the SPACEHAB module and the port 5 truss segment for mission STS-116. They will be moved into the payload changeout room (PCR) on the RSS and transferred into Space Shuttle Discovery's payload bay once the vehicle has rolled out to the pad. The PCR is the enclosed, environmentally controlled portion of the RSS that supports cargo delivery to the pad and subsequent vertical installation into the orbiter payload bay. Seals around the mating surface of the PCR fit against the orbiter and allow the opening of the payload bay or canister doors and removal of the cargo without exposure to outside air and contaminants. A clean-air purge in the PCR maintains environmental control during PCR cargo operations. Cargo is removed from the payload canister and installed vertically in the orbiter by the payload ground handling mechanism (PGHM). Photo credit: NASA/Kim Shiflett

Workers wait inside the payload canister (right) for the U.S. Lab Destiny (left) to finish its move to the canister via overhead crane. Once installed inside the canister, Destiny will be transferred to Launch Pad 39A and lifted to the payload changeout room. From there it will be moved into the payload bay of the orbiter Atlantis. Destiny is the primary payload on mission STS-98, scheduled for launch no earlier than Jan. 19, 2001

KENNEDY SPACE CENTER, FLA. -- In the early morning daylight, the payload canister containing the Chandra X-ray Observatory begins its ascent up the Rotating Service Structure (RSS). The canister arrived at the pad on the payload canister transporter below it. The canister will be lifted up to the Payload Changeout Room in the RSS where it will be relieved of its cargo. After the RSS rotates to a position behind Space Shuttle Columbia (at right), the observatory will then be installed vertically in the orbiter payload bay. The world's most powerful X-ray telescope, Chandra will allow scientists from around the world to see previously invisible black holes and high-temperature gas clouds, giving the observatory the potential to rewrite the books on the structure and evolution of our universe. Chandra is the primary payload on mission STS-93, scheduled to launch no earlier than July 20 aboard Space Shuttle Columbia (right)

Technicians use a crane to lift the payload adapter separation systems canister for the Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) as part of launch preparations inside Building 836 at Vandenberg Space Force Base (VSFB) in California on Sept. 1, 2022. The separation system canister loads into the payload adapter canister. The canister will go over the reentry vehicle.. LOFTID is the secondary payload on NASA and the National Oceanic and Atmospheric Administration’s (NOAA) Joint Polar Satellite System-2 (JPSS-2) satellite mission. JPSS-2 is the third satellite in the Joint Polar Satellite System series. It is scheduled to lift off from VSFB on Nov. 1 from Space Launch Complex-3. JPSS-2, which will be renamed NOAA-21 after reaching orbit, will join a constellation of JPSS satellites that orbit from the North to the South pole, circling Earth 14 times a day and providing a full view of the entire globe twice daily. The LOFTID is dedicated to the memory of Bernard Kutter. LOFTID will demonstrate inflatable heat shield technology that could enable a variety of proposed NASA missions to destinations such as Mars, Venus, and Titan, as well as returning heavier payloads from low-Earth orbit.

KENNEDY SPACE CENTER, FLA. -- In the Space Station Processing Facility, the overhead crane lowers the SHI Research Double Module (SHI/RDM) into the payload canister. The canister will transport it to the Orbiter Processing Facility where it will be installed in Columbia's payload bay for mission STS-107. SHI/RDM is the primary payload of the research mission, with experiments ranging from material sciences to life sciences (many rats). Also part of the payload is the Fast Reaction Experiments Enabling Science, Technology, Applications and Research (FREESTAR) that incorporates eight high priority secondary attached shuttle experiments. STS-107 is scheduled to launch July 19, 2002

CAPE CANAVERAL, Fla. - In the payload changeout room, or PCR, on Launch Pad 39A at NASA's Kennedy Space Center in Florida, workers prepare for the transfer of the cargo inside the payload canister, at left. Two of the four carriers seen behind the workers are the Orbital Replacement Unit Carrier (top) and the Super Lightweight Interchangeable Carrier. The cargo will be transferred into the PCR via the payload ground-handling mechanism, or PGHM. The PGHM removes payloads from a transportation canister and installs them into the shuttle. It is essentially NASA’s largest fork-lift. Atlantis is targeted to launch Oct. 10. Photo credit: NASA/Jim Grossmann

KENNEDY SPACE CENTER, FLA. -- Hours before dawn, the payload canister transporter delivers its cargo (lower left) to Launch Pad 39B, below the Rotating Service Structure (RSS). Inside the canister is the Chandra X-ray Observatory, primary payload on mission STS-93, scheduled to launch no earlier than July 20 aboard Space Shuttle Columbia (right). The canister will be lifted up to the Payload Changeout Room in the RSS where it will be relieved of its cargo. After the RSS rotates to a position behind Columbia, the observatory will then be installed vertically in the orbiter payload bay. The world's most powerful X-ray telescope, Chandra will allow scientists from around the world to see previously invisible black holes and high-temperature gas clouds, giving the observatory the potential to rewrite the books on the structure and evolution of our universe

The SPACEHAB Single Module is raised by crane from a transporter in KSC's Space Station Processing Facility, where it will be moved to the payload canister. It will be joined in the canister by the Alpha Magnetic Spectrometer-01 payload before being moved to Launch Pad 39A for the STS-91 mission, scheduled to launch June 2 at around 6:04 p.m. EDT. SPACEHAB is used mainly as a large pressurized cargo container for science, logistical equipment and supplies to be exchanged between the orbiter Discovery and the Russian Space Station Mir. The nearly 10-day flight of STS-91 also is scheduled to return the sixth American, Mission Specialist Andrew Thomas, Ph.D., aboard the Russian orbiting outpost safely to Earth

Processing activities for STS-91 continue in Orbiter Processing Facility Bay 2. Two Get Away Special (GAS) canisters are shown after their installation into Discovery's payload bay. The GAS payload G-765, in the canister on the left, is sponsored by the Canadian Space Agency and managed by C-CORE/Memorial University of Newfoundland. It is a study to understand the transport of fluids in porous media as it pertains to improving methods for enhanced oil recovery. The GAS canister on the right houses the Space Experiment Module (SEM-05), part of an educational initiative of NASA's Shuttle Small Payloads Project. STS-91 is scheduled to launch aboard the Space Shuttle Discovery for the ninth and final docking with the Russian Space Station Mir from KSC's Launch Pad 39A on June 2 with a launch window opening around 6:04 p.m. EDT
