Space shuttle Discovery is one step closer to its final departure from Central Florida on the back of a 747.

The modified jet that will carry the retired shuttle to its new home at the Smithsonian National Air and Space Museum, in Washington, arrived around 5:30 p.m. Tuesday at the Kennedy Space Center.

The jet carrying Discovery is scheduled to leave the Kennedy Space Center on the back of the jet Tuesday, April 17, at 7 a.m.

The Smithsonian is currently home to the prototype space shuttle Enterprise, which will be moved to New York City later in April to make room for Discovery.

Following Discovery, shuttle Endeavour is next to move to its new, permanent home. Endeavour is scheduled to head to the California Science Center, in Los Angeles, in September.

Atlantis, which is staying in Central Florida, is scheduled to make the short trip to the Kennedy Space Center Visitor Complex in 2013.
