Dawn, Friday June 17, 2011, at Kennedy Space Center Launch Pad 39-A. Atlantis is on the pad, and the RSS (rotating service structure) is open. During the night the final payload in the shuttle program arrived at the pad ready to be placed in the Atlantis cargo bay.
The media and KSC employees were invited to visit 39-A on Friday, June 17, 2011.
Shuttles were launched from either Pad 39-A or Pad 39-B during the shuttle program from 1981 to 2011. Today only Pad 39-A remains.
Pad 39-B was in the process of being repurposed for the Constellation program, when President Obama canceled the Constellation program, reinstated it, and then canceled it again.
The future of both Pad 39-A and the now demolished Pad 39-B, like the future of the American spaceport at Kennedy Space Center, is uncertain.
