Space Shuttle Pathfinder

The Space Shuttle Pathfinder is a 75-ton Space Shuttle mock-up made of steel. It was initially built and used by NASA to practise handling and moving of actual Space Shuttles (as made possible by the mock-up's similarity in size, weight and shape). It was later purchased by a Japanese organization who refurbished the steel mock-up to more closely resemble an actual Space Shuttle and named her the Pathfinder, for purposes of showing it in a Tokyo, Japan space exhibition. The Pathfinder has since been returned to the U.S. and is presently on display at the Alabama Space and Rocket Center in Huntsville, Alabama.
