The Advanced Tether Experiment (ATEx, USA 141) was designed to extend the knowledge of control and survivability of tethered space systems. Experiments in active control were to study deployment dynamics via a constant-speed motor and utilization of both in-plane and cross-plane thrusters to excite and arrest librations. Additionally, ATEx was to investigate the survivability of long-life tether materials.
