This out-of-the-window view from the space shuttle shows the Autonomous Extravehicular Activity Robotic Camera Sprint (AERCam Sprint) free-flying in the vicinity of the cargo bay of the Earth-orbiting Space Shuttle Columbia. The AERCam Sprint is a free-flying video-camera-equipped robot that can be used for remote inspections of the exterior of the International Space Station (ISS).
It is a 14-inch diameter, lithium-battery powered 35-pound sphere with two TV cameras, an avionics system and 12 small nitrogen gas-powered thrusters. The front is marked by stripes and arrows, and the back by dots, to assist the operator. The aerial view, back dropped over southern Madagascar, was taken on December 3, 1997. Photo courtesy of NASA.
