If you want to go inside one of the most amazing and off-limits places in Florida, you have one week left to do it.

Tours of theVehicle Assembly Building at the Kennedy Space Center will end on Sunday, February 23rd.

It's the building where NASA prepared the moon rockets and the space shuttle for launch.

It's also one of the largest buildings in the world -- so big, clouds can form inside, just below the ceiling.

Tourists have been able to go inside for rare tours for about two years. Before that, the building had been closed to the public since 1978.

NASA says it needs to start getting the VAB ready for the next program that will take Americans into space on rockets built here in the United States.

You'll want to book your tour early, online. Go to the Kennedy Space Center Visitor Complex website to book a VAB tour.
