CAPE CANAVERAL, Fla. – Tugboats maneuver the Pegasus barge toward the dock in the turn basin in the Launch Complex 39 Area in NASA's Kennedy Space Center. Onboard the barge is the external fuel tank for space shuttle Atlantis' STS-125 mission to NASA's Hubble Space Telescope. After docking, the tank will be offloaded and moved to the Vehicle Assembly Building. Once inside the building, the tank will be raised to vertical, lifted and moved into a checkout cell. Stacking of the tank and solid rocket boosters is planned to start Aug. 7. Atlantis is targeted to launch Oct. 8. Photo credit: NASA/Jack Pfaller

Saudi Arabia is in the foreground and Egypt?s Nile River and its delta can be seen (left) toward the horizon. Israel and Jordan can be seen near the top edge of the frame. The Gulf of Suez and the Gulf of Aqaba (near frame center) extend from the Red Sea toward the Mediterranean Sea.

STS132-S-125 (26 May 2010) --- Space shuttle Atlantis' main gear touches down on Runway 33 at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. Landing was at 8:48 a.m. (EDT) on May 26, 2010, completing the 12-day STS-132 mission to the International Space Station. Main gear touchdown was at 8:48:11 a.m., followed by nose gear touchdown at 8:48:21 a.m. and wheelstop at 8:49:18 a.m. Onboard are NASA astronauts Ken Ham, commander; Tony Antonelli, pilot; Garrett Reisman, Michael Good, Steve Bowen and Piers Sellers, all mission specialists. The six-member STS-132 crew carried the Russian-built Mini Research Module 1 (MRM1) to the orbital complex. STS-132 is the 34th shuttle mission to the station, the 132nd shuttle mission overall and the last planned flight for Atlantis.

CAPE CANAVERAL, Fla. – Inside the Vehicle Assembly Building at NASA's Kennedy Space Center, technicians replace a valve on Atlantis’ external tank 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.

Johnson, pilot; Michael Good, Megan McArthur, John Grunsfeld, Mike Massimino and Andrew Feustel, all mission specialists. Atlantis' 11-day flight will include five spacewalks to refurbish and upgrade the telescope with state-of-the-art science instruments that will expand Hubble's capabilities and extend its operational lifespan through at least 2014. The payload includes Wide Field Camera 3, fine guidance sensor and the Cosmic Origins Spectrograph.

CAPE CANAVERAL, Fla. – Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center, a technician removes a valve from Atlantis’ external tank 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/Dimitri Gerondidakis

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.
