TechSat-21 (Technology Satellite of the 21st Century) was a small spacecraft developed by the U.S. Air Force Research Laboratory’s Space Vehicles Directorate to test technology for formation flight of spacecraft which can rapidly change formation based on mission requirements.[1] The project was canceled in 2003 due to numerous cost overruns.[2]
