EDWARDS, CA - MAY 23:  The sun rises behind the modified Boeing 747 Space Shuttle Carrier Aircraft (SCA) that will be used to ferry Space Shuttle Atlantis to Kennedy Space Center in Florida if it lands in California, as NASA abandons off attempts to land at either location today on May 23, 2009 at Edwards Air Force Base near Mojave, California. Thunderstorms, rain and low clouds are hindering NASA from landing at its preferred site in Florida. The eventual landing will conclude mission STS-125 to the Hubble Space Telescope where the astronauts performed five spacewalks during an 11-day mission to repair and upgrade the telescope.
