The Final Frontier
NASA set to announce the museums the Space Shuttle fleet will reside in after they're retired later this year.
With the Space Shuttle era coming to an end museums across the country are making a pitch to land one of the three remaining space crafts.
On Tuesday NASA is expected to announce the winners of the permanent homes for the last three shuttles.
After more than two years of behind-the-scenes lobbying NASA will announce where Discovery, Endeavour and Atlantis will be placed on permanent public display.
While officials won't comment, it is widely believed the Smithsonian will get Discovery,
which would likely mean the current shuttle there, The Enterprise, a trainer that has never been in orbit, would go to one of the other contenders.
That list includes the national museum of the U.S. Air Force in Dayton, Ohio.
The Air Force Museum is considered a front runner in part because of the influence of former senator and astronaut John Glenn.
The Museum of Flight in Seattle has already started work on a new wing for a shuttle, and in New York the Intrepid Museum argues it can provide the biggest spotlight.
The visitors complex at Kennedy Space Center in Florida, where every shuttle has started its journey, is also considered a sentimental favorite.
