The Space Flyer Unit (SFU) is an unmanned free fling small platform for onboard experiments on space science and engineering, which is the first retrievable carrier inJapan. The major objective of the first SFU mission is to establish a reusable spacecraft system, and the second is to carry out various onboard experiments on space science and engineering. The SFU was launched in orbit byJapanese H-II-3 rocket on March 18, 1995, and retrieved by American Space Shuttle STS-72 on January 20, 1996. When the first SFU mission completed, SFU was broken up for storing until second flight integration. After two years discussion about the second flight mission, it was decided to handover to the National Science Museum of Japan for future scientific and engineering education. Many young graduate and university students in their subject of space engineering jointed to re-integration activities of this spacecraft.
