This image of space shuttle Atlantis was taken shortly after the rotating service structure was rolled back at Launch Pad 39A, Thursday, July 7, 2011. Atlantis is set to liftoff today, Friday, July 8, at 11:26 a.m. EDT on the final flight of the Space Shuttle Program.
We also have a nice video retrospective of the shuttle program over at NPR.org. —Wright
