Space simulation testing facility
Realistic laboratory devices like the Visual Docking Simulator used at the National Aeronautics And Space Administration Langley Research Center play an ever-increased role in NASA's space research as scientists seek to learn how well human pilots can do the job of bringing two orbiting spacecraft to a safe, accurate docking. From the co-pilot's point of view inside the simulated Gemini cockpit, the image of the Agena, with United States painted clearly on its side, looms through the left hand window. Instrument dials glow in the darkness as the pilot gently moves his control handle.
