The U.S. Air Force micro-satellite, Experimental Satellite System-11 (XSS-11) has been busy testing its ability to demonstrate space rendezvous skills.

Launched in April, the spacecraft has made multiple run-ups with the upper stage of the Minotaur I upper stage that tossed it into orbit. XSS-11 closed in to about 1,640 feet (500 meters) from the spent stage in one maneuver.

The spacecraft is slated to conduct rendezvous and proximity maneuvers with several U.S.-owned dead or inactive resident space objects near its orbit – thereby showcasing more onboard autonomy to perform such duties as the project continues. 

 
The XSS-11 was developed by the Air Force Research Laboratory, Space Vehicles Directorate, at Kirtland Air Force Base in New Mexico. The $82 million program is investigating a variety of prospective space applications including servicing, repair, and re-supply of spacecraft.

The XSS-11 project represents a partnership between DOD and industry. For example, Lockheed Martin Astronautics served as the spacecraft’s contractor for structure, propulsion, and system support.
