Flown star chart carried into lunar orbit on board Apollo 10. Chart measures 10.75 x 7.5, with “May 18th Launch LM,” printed in the lower border and shows the Sun, Earth, and the planets aligned on the ellipse. Specific stars and constellations are identified by name and assigned a two-digit number code. Signed along the bottom in black felt tip, “Flown on Apollo X, Gene Cernan,” and “Tom Stafford, Apollo X, cdr.” Chart has several pencil notations along the top edge, as well as several lines and circles in the chart, presumably done by Cernan. In fine condition, with a bit of scattered light soiling. Accompanied by a 2005 letter of authenticity from Gene Cernan, which reads, in part: “This is to certify that the accompanying Apollo 10 Star Chart was flown into lunar orbit in May, 1969 aboard our spacecraft…This Star Chart has remained a treasured part of my personal collection for more than thirty-five years, ever since NASA presented it to me back in 1969.” Also included is a photo of Cernan with the chart and letter. Necessary to plot locations and coordinates, this chart was used to update both ‘Charlie Brown’s’ and ‘Snoopy’s’ positions during the critical and final tests before the first manned lunar mission.
