CAPE CANAVERAL, Fla. - At NASA’s Kennedy Space Center, space shuttle Endeavour is slowly lifted into the upper levels of the Vehicle Assembly Building for transfer into high bay 1 for mating with its external fuel tank and solid rocket boosters, seen below it. After additional preparations are made, the shuttle will be rolled out to Launch Pad 39B. Endeavour is designated the rescue spacecraft for space shuttle Atlantis’ STS-125 mission to NASA’s Hubble Space Telescope, targeted for October. After Atlantis has safely returned from its flight, Endeavour will be moved to Launch Pad 39A for its STS-126 mission to the International Space Station, targeted for November.
