An aerial view south along the seashore shows shuttles on both launch pads. The Atlantic Ocean is a thin line on the horizon. 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. At right is space shuttle Endeavour, which rolled out Sept. 19, completing the 4.2-mile journey at 6:59 a.m. EDT. This is the first time since July 2001 that two shuttles are on the launch pads at the same time at the center. 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 credit: NASA/Troy Cryder
