NASA is announcing where the retiring space shuttles will go on display once the program ends this summer.
Twenty-one museums and centers around the US put in bids for the spaceships. NASA is disclosing the winners on Tuesday on the 30th anniversary of the first space shuttle launch in 1981.
The shuttle program is winding down with only two more flights left. Shuttle Discovery ended its flying career last month and it's going to the Smithsonian Institution in Washington.
Up for grabs are shuttles Endeavour and Atlantis and the prototype Enterprise.
Some of the hot contenders are visitor centers at Kennedy Space Center and Johnson Space Center, the Air Force Museum in Ohio and museums in New York City, Seattle and Chicago.
