Suspended by an overhead crane, space shuttle Endeavour is being raised to a vertical position in the transfer aisle of the Vehicle Assembly Building at NASA’s Kennedy Space Center. The shuttle will be lifted into high bay 1 for mating with its external fuel tank and solid rocket boosters. 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.
