In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center, workers attach an overhead crane to the Orbital Replacement Unit Carrier, or ORUC. The crane will lift and move the ORUC to the payload canister. The carrier is one of four associated with the STS-125 mission to service the Hubble Space Telescope. It will be 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. Photo credit: NASA/Jack Pfaller
