CAPE CANAVERAL, Fla. – In the Vehicle Assembly Building at NASA's Kennedy Space Center, the external tank for space shuttle Atlantis is lowered toward the solid rocket boosters (the nose cone of one of the boosters is seen here) for mating. The tank and boosters will be secured on the mobile launcher platform below. Atlantis' STS-125 mission is the fifth and final shuttle servicing mission to NASA’s Hubble Space Telescope. Launch is targeted for Oct. 8. Photo credit: NASA/Jack Pfaller KSC-08pd2265

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

CAPE CANAVERAL, Fla. – Inside a test cell in the Vehicle Assembly Building at NASA's Kennedy Space Center, a portion of Atlantis’ external tank is sealed to prevent contamination so that technicians can replace a valve after small dings were found on the sealing surface of the quick disconnect system that handles liquid-hydrogen fuel for the shuttle’s three main engines. The tank will be attached to the twin solid rocket boosters on Aug. 3 for the STS-125 mission, the fifth and final shuttle servicing mission to NASA’s Hubble Space Telescope. During the mission, the crew will install new instruments on the telescope, including the Cosmic Origins Spectrograph and the Wide Field Camera 3. A refurbished Fine Guidance Sensor will replace one unit of three now onboard. Mission specialists will also install new gyroscopes, batteries and thermal blankets on the telescope. Launch is targeted for Oct. 8. Photo credit: NASA/Jim Grossmann KSC-08pd2152

CAPE CANAVERAL, Fla. – A view from above of repairs made to the walls of the Launch Pad 39A flame trench at NASA's Kennedy Space Center. Workers sprayed a heat-resistant concrete called Fondue Fyre into steel grid structures, welded to the wall of the flame trench. Fondue Fyre was developed during NASA's Apollo lunar program. Damage to the trench occurred during the launch of space shuttle Discovery on the STS-124 mission. A 75-foot by 20-foot section of the east wall was destroyed and debris scattered as far as the pad perimeter fence. Repairs being completed before the targeted Oct. 8 launch of Atlantis on the NASA Hubble Space Telescope servicing mission. Photo credit: NASA/Dimitri Gerondidakis KSC-08pd2377

CAPE CANAVERAL, Fla. – A close up view of the valve removed from Atlantis’ external tank inside the Vehicle Assembly Building at NASA’s Kennedy Space Center. Technicians removed the valve after small dings were found on the sealing surface of the quick disconnect system that handles liquid-hydrogen fuel for the shuttle’s three main engines. The tank will be attached to the twin solid rocket boosters on Aug. 3 for the STS-125 mission, the fifth and final shuttle servicing mission to NASA’s Hubble Space Telescope. During the mission, the crew will install new instruments on the telescope, including the Cosmic Origins Spectrograph and the Wide Field Camera 3. A refurbished Fine Guidance Sensor will replace one unit of three now onboard. Mission specialists will also install new gyroscopes, batteries and thermal blankets on the telescope.

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. High winds, however, have delayed the transfer. 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-08pd3114
