A rainbow completes this unique panorama of two space shuttles on the launch pads at the same time, the first time since July 2001. At upper right is STS-126 mission’s space shuttle Endeavour, which rolled out Sept. 19. At left is space shuttle Atlantis, preparing for its launch on the STS-125 mission to repair NASA's Hubble Space Telescope, targeted for Oct. 10. Endeavour will stand by at pad B in the unlikely event that a rescue mission is necessary during space shuttle Atlantis' upcoming mission. After Endeavour is cleared from its duty as a rescue spacecraft, it will be moved to Launch Pad 39A for the STS-126 mission to the International Space Station. That flight is targeted for launch Nov. 12. Photo courtesy of NASA.
