high-autonomy intelligent command and control architec-h ure has been developed for unmanned plants to conduct scientific experiments or process local planetary resources. Two applications are: a biotechnology laboratory designed for Space Station Freedom and a working prototype of a plant for producing oxygen fr'om the Martian atmosphere. Adistributed command and control architecture has been designed to teleoperate such plants L.C. Schooley, B.P Zeigler and EE.

NASAin a high-level task oriented mode with supervisory control from one or several remote sites. The architecture integrates advanced network communication concepts and modem madmachine interfaces with recent advances in autonomous intelligent control. A complete testbed has been developed to demonstrate several applications of the architecture. High Autonomy within Remote Supervisory ControlA distributed command and control architecture has been developed to provide the capability to teleoperate one or several process plants located on Mars, Luna, the asteroids, andor other objects in space in a supervisory control mode from one or several locations on planet Earth. The architecture is able to guarantee autonomous, reliable, and robust control over an extended time period with high-level task-oriented teleoperation. June 19!)3
