CAPE CANAVERAL, Fla. (AP) — NASA may move up its final trip to the Hubble Space Telescope by one day.

Space shuttle Atlantis could blast off with its telescope repair crew as early as May 11th, if the Hubble team can complete all its flight preparations in time. NASA wants to have extra time to get the mission off, before having to get in line behind the Air Force. A military operation planned for mid-May would delay the shuttle launch by more than a week.

Hubble program manager Preston Burch says he'll know better in a week if his team can make a launch on the 11th. Liftoff has been targeted for May 12th.
