![Agena Spacecraft Aspect Indicator Instrument Model. An Agena spacecraft model inside an approx. 6 in. diameter sphere mounted on an 8 in. circular base. Overall height is approx. 18 in. NASA used the Agena as docking target and high altitude propulsion system during the Gemini Program. The instrument was designed as a visual aid relating to problems concerning aspect angles of maneuvering space vehicles. The sphere containing the Agena has calibrated two axis movement as well as movement along the semi-circle mounting frame and a tilt movement at the center of the base stand. The instrument provided NASA and military space planners a means of measurement and interpretation from a given vehicle orientation.
