CAPE CANAVERAL, Fla. – On Launch Pad 39A at NASA's Kennedy Space Center in Florida, the rotating service structure is open, revealing space shuttle Atlantis on the pad for the STS-125 mission, the fifth and final shuttle servicing mission for NASA’s Hubble Space Telescope. On the RSS, the payload canister is in position at the payload changeout room to receive the Hubble hardware. The payload comprises four carriers holding various equipment for the mission. The hardware will be transported back to Kennedy’s Payload Hazardous Servicing Facility where it will be stored until a new target launch date can be set for Atlantis’ STS-125 mission in 2009. Atlantis’ October target launch date was delayed after a device on board Hubble used in the storage and transmission of science data to Earth shut down on Sept. 27. Replacing the broken device will be added to Atlantis’ servicing mission to the telescope. Photo credit: NASA/Tim Jacobs KSC-08pd3113
