Vintage Mercury star chart from the personal collection of flight director Gene Kranz. This star chart is a part of a full set of charts used by Mercury Astronauts assigned to Remote Tracking Stations. By using the correct star chart and a clear overlay (not included) in the shape of a spacecraft window, they were able to see the same view being seen by the orbiting astronaut from his capsule window. This laminated double-sided chart measures 3.5 x 10.25 with many stars and constellations identified. Accompanied by a certificate of authenticity from Farthest Reaches. A seldom seen artifact of the Mercury Program. RRAuction COA.
