Flown star chart carried on board the Gemini 5 mission from August 21–28, 1965. Chart measures approximately 9.75″ in diameter and is labeled, “CF55062-I Serial No. 54.” All major stars, planets, and constellations visible from orbit are plotted underneath a rotating translucent position locator and include the moon, Venus, Mars, Saturn, Jupiter, the Sun, Virgo, and Libra. In fine condition, with some expected wear and tape from use. Accompanied by a signed certificate of authenticity from Charles Conrad, in part: “This is to certify that the star chart…CF55062-1 Serial No. 54…was flown onboard Gemini 5 with Astronauts Charles P. Conrad and L. Gordon Cooper.” Cooper has also signed the certificate in black ink, “8 Days or Bust! Gordon Cooper, Commander Gemini V.” Also accompanied by a photo of Cooper holding the chart and certificate. Backed by its strong provenance, this is a rare navigational tool crucial to the safe and successful journey of the third manned Gemini flight.
