The was a spacecraft which was launched by Japan on March 18, 1995. Technical data The Space Flyer Unit was launched from Tanegashima Space Center from a H-II vehicle. It carried testing materials and research data that held value to NASA. The crew of STS-72 aboard Space Shuttle Endeavour retrieved the satellite on January 20, 1996, 10 months after it was launched. The idea behind the implementation of the SFU was a joint effort by multiple major corporations and government agencies. The ones that were involved with the launch were Institute of Space and Astronautical Science, the National Space Development Agency, and Ministry of International Trade and Industry. After the shuttle returned the SFU from space it was transported to Japan and refurbished for display at the National Museum of Nature and Science in Tokyo. Purpose The original purposes behind the SFU were to Allow researchers better access to space research conditions. Give researchers a group experimental facility. Be able to reuse the SFU to save money Retrieve data Technology A variety of systems that were operational within the SFU had never been implemented before. Equipment on board supported an infrared telescope, two-dimensional solar array, high voltage solar array, space plasma diagnosis, electric propulsion, material experimentation, gas dynamics, gradient heating chemicals, isothermal heating furnace and more. The core system that was built into the SFU contained an octagonal aluminum truss. Inside of that were eight boxes of trapezoidal shape. The SFU was connected directly to the Kagoshima Space Center. Experimentation data There were a number of various types of experiments that were performed on board the SFU during its launch life cycle. Those experiments, and light data related to them are listed below. Infrared Telescope in Space (IRTS) - The IRTS experiment was performed by the infrared telescope that was aboard the SFU. The intent was to produce important information into the history of the universe and structure of the milky way galaxy. The telescope had a super fluid helium cooling fan built into it to prevent it from overheating. 2D Array - The 2d array system was launched as a small module inside of the SFU. This experiment was deployed to show that large structures could (in fact) be built in space. HVSA - The Solar Array was a power source put into this system to head up multiple experiments. It is used to test the creation of "electricity"
