In the Launch Complex 39 Area at NASA's Kennedy Space Center, the external tank for space shuttle Atlantis' STS-125 mission to NASA's Hubble Space Telescope is ready to be moved off the Pegasus barge and moved to the Vehicle Assembly Building. 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 scheduled for Aug. 7. Atlantis is targeted to launch Oct. 8. Photo credit: NASA/Amanda Diller
