The Air Force's Shadowy Space Drone Comes Back Down To Earth http://webcache.googleusercontent.com/search?q=cache:uFTltwHAqAkJ:foxtrotalpha.jalopnik.com/the-air-forces-shadowy-space-drone-comes-back-down-to-e-1647902456/1647923004/%2Bdamon+&cd=23&hl=en&ct=clnk&gl=us midway down in the article: The long endurance, reusable space drone has been accused of doing many things, including mundane research into unmanned re-usable space vehicles, visually spying on an as yet to be completed Chinese space station, containing quick strike weapons for time sensitive targets, flying up to satellites to fix, refuel or disable them in a 'hands on' fashion, testing lasers that can blind enemy spy satellites, and even deploying "quantum dots" for use as an anti-satellite weapon countermeasure. Above all these potential missions, carrying experimental reconnaissance payloads into low-earth orbit is probably the most plausible of the bunch. with link: http://www.google.com/patents/US7916065
