LAC 12 Plato Relief Rendition Lunar Astronautical Chart series 1st Edition January 1967

"Extremely rare complete set of the celebrated lunar maps produced during the heyday of the space race as part of the Apollo program. Inspired by the success of the 1960 “Lunar Photographic Atlas” by the astronomer Gerard Peter Kuiper (see our 14057.000 and 14059.000), the U.S. Air Force set out to produce detailed charts, racing to collect the scientific data needed in order to put a man on the moon. With the exception of Wilhelm Gotthelf Lohrmann (see our 11245.000) and perhaps Tobias Mayer (see our 11294.017), this was the first time that professional cartographers were called in to deal with the problem of mapping the lunar surface. Installing themselves at Lowell Observatory in Arizona, they combined earth-based telescope observations with existing photographs, sources including the University of Manchester station sponsored by the ACIC at Pic du Midi, the Stony Ridge Observatory in California, the Kwasan Observatory in Kyoto, and their own motion picture films taken at Lowell, in order to create lucid maps, concluding that lunar features could be artistically drawn and airbrushed with India ink on translucent plastic sheets, following the style of lead illustrator Patricia Bridges. With the workload constantly increasing, the workforce grew to a maximum of 18 persons in 1966. The moon was divided into 68 quadrants (although the numbers run from 1 to 144, including the far side), each chart consisting of a topographic map recto and a relief rendition verso. The LAC series remained the most detailed lunar maps at NASA until the photographs taken on orbital missions. superseded by the results of the later Apollo flights, these historic maps were discarded and many sets destroyed. A milestone of scientific mapmaking and a rare survival." (Antiquariat INLIBRIS, 2021) Note: only 30 of the 44 maps have the relief rendition on the verso. The maps use Mercator and Lambert Conformal Conic projections. They are known as the Lunar Chart (LAC) Series. See our 12101.000 for the 1972 Geologic Atlas of the Moon, which was based on these sheets, updated.
