ISS036-E-003308(23 May 2013) -- Onboard the International Space Station, Expedition 36 Flight Engineer Chris Cassidy, NASA astronaut, watches from just out of frame as he devotes some time with the long-running SPHERES experiment, also known as Synchronized Position Hold Engage and Reorient Experimental Satellites. The experiment is run in conjunction with students who program bowling ball-sized satellites using algorithms. The free-floating satellites are programmed to perform maneuvers potentially influencing the design of future missions.
