This payload canister is being transported to Launch Pad 39A for a "fit check." At a later date, the canister will be used to transport to the pad the S3/S4 solar arrays that are the payload for mission STS-117. The mission will launch on Space Shuttle Atlantis for the 21st flight to the International Space Station, and the crew of six will continue the construction of station with the installation of the arrays. The launch of Atlantis is targeted for March 16.

CAPE CANAVERAL, Fla. - The payload canister moves back into the environmentally controlled high bay of the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center. The canister was moved out of the high bay during contamination of the Super Lightweight Integration Carrier, one of four associated with the STS-125 mission to service the Hubble Space Telescope. The carriers are being installed in the payload canister for transfer to Launch Pad 39A. At the pad, all the carriers will be loaded into space shuttle Atlantis’ payload bay. Launch of Atlantis is targeted for Oct. 10. On the left next to the canister is the Multi-Use Logistic Equipment, or MULE, carrier, which will be transferred to the canister.

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

CAPE CANAVERAL, Fla. -- Payload canister #1 departs the high bay of the Canister Rotation Facility at NASA's Kennedy Space Center in Florida for the last time. The canister is being moved to the Reutilization, Recycling and Marketing Facility on Ransom Road. The two payload canisters used to transport space shuttle payloads to the launch pad for installation in the shuttles' cargo bays are being decommissioned following the end of the Space Shuttle Program. Each canister weighs 110,000 pounds and is 65 feet long, 22 feet wide, and 18 feet, 7 inches high. The canisters were prescreened through NASA Headquarters as possible artifacts, but their size makes them difficult to transport to locations off the center. Federal and state agencies now will be given the opportunity to screen the canisters for potential use before a final decision is made on their disposition.

KENNEDY SPACE CENTER, FLA. - After a several-hour trip from the Canister Rotation Facility, the payload canister arrives on Launch Pad 39B. Inside the canister is the payload for Atlantis and mission STS-115, the Port 3/4 truss segment with two large solar arrays. The canister will be positioned alongside the rotating service structure and beneath the payload changeout room (PCR) for transfer of the truss into the PCR. The payload changeout room provides an environmentally clean or "white room" condition in which to receive a payload transferred from a protective payload canister. After the shuttle arrives at the pad, the rotating service structure will close around it and the payload will then be transferred into Atlantis' payload bay. Atlantis' launch window begins Aug. 28. During its 11-day mission to the International Space Station, the STS-115 crew of six astronauts will install the truss, a 17-ton segment of the space station's truss backbone.

The Microgravity Science Laboratory-1 (MSL-1) Spacelab module is moved to be installed into a payload canister in the Operations and Checkout Building. Once in the canister, the MSL-1 will be transported to Orbiter Processing Bay 1 where it will be integrated into the payload bay of the Space Shuttle orbiter Columbia. During the scheduled 16-day STS-83 mission, the MSL-1 will be used to test some of the hardware, facilities and procedures that are planned for use on the International Space Station while the flight crew conducts combustion, protein crystal growth and materials processing experiments

CAPE CANAVERAL, Fla. – On Launch Pad 39A at NASA's Kennedy Space Center, the payload canister has been lifted up to the payload changeout room for transfer of its cargo. Inside the canister are the Japanese Experiment Module - Pressurized Module and the Japanese Remote Manipulator System, or RMS, for the STS-124 mission. 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. Photo credit: NASA/Kim Shiflett

CAPE CANAVERAL, Fla. -- Payload canister #2 approaches the Space Station Processing Facility for a group employee photo opportunity. The canister is on its way from the Canister Rotation Facility at NASA's Kennedy Space Center in Florida to the Reutilization, Recycling and Marketing Facility on Ransom Road. The two payload canisters used to transport space shuttle payloads to the launch pad for installation in the shuttles' cargo bays are being decommissioned following the end of the Space Shuttle Program. Each canister weighs 110,000 pounds and is 65 feet long, 22 feet wide, and 18 feet, 7 inches high. The canisters were prescreened through NASA Headquarters as possible artifacts, but their size makes them difficult to transport to locations off the center. Federal and state agencies now will be given the opportunity to screen the canisters for potential use before a final decision is made on their disposition.
