CAPE CANAVERAL, Fla. – Just before dawn, space shuttle Endeavour is bathed in xenon lights after being  secured on Launch Pad 39B at NASA's Kennedy Space Center in Florida.  First motion on rollout from the Vehicle Assembly Building was at 11:57 p.m. EDT April 16.  On either side of the pad are two of the new lightning towers erected for NASA's Constellation Program, which will use the pad for Ares rocket launches.  Endeavour will be prepared on the pad for liftoff in the unlikely event that a rescue mission is necessary following space shuttle Atlantis' launch on the STS-125 mission to service NASA's  Hubble Space Telescope. After Atlantis is cleared to land, Endeavour will move to Launch Pad 39A for its upcoming STS-127 mission to the International Space Station, targeted to launch June 13.

CAPE CANAVERAL, Fla. – After space shuttle Endeavour's rollout to Launch pad 39B at NASA's Kennedy Space Center in Florida this morning, two different shuttles are poised on two different launch pads.  Shuttle Atlantis (right) already was on Launch Pad 39A.   With the space shuttle fleet set for retirement in 2010, this is expected to be the final time two shuttles will be on launch pads at the same time.  Endeavour will stand by at pad B in the unlikely event that a rescue mission is necessary during Atlantis' upcoming mission to upgrade NASA's Hubble Space Telescope. Atlantis is targeted to launch May 12. After Endeavour is cleared from its duty as a rescue spacecraft, it will be moved to Launch Pad 39A for its STS-127 mission to the International Space Station. That flight is targeted for launch June 13.   Photo credit: NASA/Kim Shiflett

CAPE CANAVERAL, Fla. – On Launch Pad 39A at NASA's Kennedy Space Center in Florida, the rotating service structure around space shuttle Atlantis begins to open to enable delivery and transfer of Atlantis' payload on April 18. After space shuttle Endeavour's rollout to Launch pad 39B at NASA's Kennedy Space Center in Florida this morning, two different shuttles now are poised on two different launch pads in full view. With the space shuttle fleet set for retirement in 2010, this is expected to be the final time two shuttles will be on launch pads at the same time.  Endeavour will stand by at pad B in the unlikely event that a rescue mission is necessary during space shuttle Atlantis' upcoming mission. Atlantis is targeted to launch May 12.
