Space Shuttle Pathfinder cost of US$1 million and hired Teledyne Brown Engineering to refurbish it to more closely resemble an actual Space Shuttle. It was named "Pathfinder" and displayed at the Great Space Shuttle Exposition in Tokyo from June 1983 to August 1984. After the exhibit, "Pathfinder" returned to the United States.
