CAPE CANAVERAL, Fla. -

NASA's Kennedy Space Center hosted a ceremonial topping out at the KSC Visitor Complex, which will be the home of the space shuttle Atlantis exhibit.

The ceremony commemorates a major milestone in the ongoing construction of the flagship attraction at the KSC Visitor Complex, which is run by Delaware North Companies Parks & Resorts.

The future home of Atlantis is set to open in the Summer of 2013.

The $100 million, 65,000 square foot exhibit for space shuttle Atlantis will be the main  element of the Kennedy Space Center Visitor Complex's 10-year master plan, according to a KSC release.

"It's the end of the shuttle actually flying in space but it's the beginning of being able to tell that tremendous story forever," said Bob Cabana, KSC director.

The Atlantis exhibit will tell the story of the 30 year Space Shuttle program, while allowing guests to look at the complex vehicle up-close.

"I'm humbled by this whole thing, but I'm proud to be part of it," said construction worker Jim Collins.
