ISS036-E-037288 (27 Aug. 2013) — In the International Space Station’s Kibo laboratory, NASA astronaut Karen Nyberg, Expedition 36 flight engineer, conducts a session with a pair of bowling-ball-sized free-flying satellites known as Synchronized Position Hold, Engage, Reorient, Experimental Satellites, or SPHERES. Surrounding the two SPHERES mini-satellites with ring-shaped hardware known as the Resonant Inductive Near-field Generation System, or RINGS, Nyberg performed a demonstration of how power can be transferred between two satellites without physical contact. Station crews beginning with Expedition 8 have operated these robots to test techniques that could lead to advancements in automated dockings, satellite servicing, spacecraft assembly and emergency repairs.
