Space shuttle Atlantis is inside the protective confines of the Vehicle Assembly Building after being moved from Launch Pad 39A Monday morning. The shuttle will remain assembled for launch position until a new target date is set for its servicing mission to NASA's Hubble Space Telescope.
Problems that developed with the Hubble in space forced NASA to postpone the Atlantis' STS-125 flight while managers reassess the mission's plans.
With Atlantis tucked safely in the VAB, workers are turning their attention to Endeavour, now on Launch Pad 39B. Riding a crawler just as Atlantis did, Endeavour is to move to Launch Pad 39A on Saturday in preparation for a mission to the International Space Station.
Endeavour is targeted to lift off Nov. 14 on mission STS-126. It will be moved so work can continue to modify Launch Pad 39B to host the Ares I-X test flight next year.
