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.
