Space Tethered Autonomous Robotic Satellite (STARS) project has carried since January 2005 under the leadership of Kagawa University. The STARS will be launched by the H2A rocket under operation of Japan Aerospace Exploration Agency (JAXA). The main objective of STARS project is technical verification for a tethered space robot, which is connected to a mother spacecraft through tether. Major consequence of the multi-body nature of the system is that its attitude can be controlled under tether tension by its own link motion. "STARS" consists of mother and daughter satellites connected by tether. The mother satellite deploys tether having the daughter satellite, which is a tethered space robot. For the purpose of the main mission: (1) Mother Satellite deploys tether having Daughter Satellite at its end; (2) Daughter Satellite controls attitude and takes a picture of Mother Satellite; (3) Mother Satellite and Daughter Satellite communicate through Bluetooth.
