Dave Scott's flown "Standard Apollo Star Chart" carried into lunar orbit during the Apollo 15 mission, 16 x 8, signed and flight-certified on the reverse in blue ballpoint, "This star chart flown to the moon on Apollo 15, July 26-Aug 7, 1971. Dave Scott Apollo 15 CDR." The start chart includes the names of all Apollo navigation stars as well as trace lines that form the constellations used to locate and identify the stars. The chart is designed with the constellations aligned on the ecliptic, with specific stars used for Apollo navigation identified, named, and numbered with a two-digit numerical code ranging 1 (Alpheratz) to 45 (Fomalhaut). The chart was used to identify and locate specific stars such that an onboard optical device, the Sextant, could be used to determine the orientation of the spacecraft relative to an onboard Inertial Measurement Unit (IMU); the onboard computer (the Apollo Guidance Computer) would then calculate the location of the craft in inertial space. The chart was also used for navigation during both translunar and transearth trajectories. In very good to fine condition, with three vertical folds and scattered creasing. Accompanied by a signed letter of authenticity from Scott, in part: “I hereby certify that the ‘Standard Apollo Star Chart’ included with this letter was used for six days in lunar orbit during Apollo 15, the first extended scientific exploration of the Moon, July 26-August 7, 1971…As the mission commander of Apollo 15, I was in charge of the handling, use and dissemination of the Flight Data File, as such, this Standard Apollo Star Chart has been in my personal collection since NASA presented it to me upon our return to Earth." A highly displayable flown Apollo star chart backed by rock solid provenance from history’s seventh moonwalker.
