Space shuttle Atlantis on pad 39A, left, and space shuttle Endeavour on pad 39B stand ready at Kennedy Space Center in Cape Canaveral, Fla., Friday, Sept. 19, 2008. Atlantis is scheduled for an Oct. 10 launch on mission STS-125 to service the Hubble Space Telescope. Endeavour will be on standby in the unlikely event that a rescue mission for the Atlantis’s crew would be necessary. It is the first time since 2001 - when flights were more closely spaced - that both of NASA’s shuttle pads have been occupied. And it will probably be the last.
