Important Lunar Mapping at the Start of the Space RaceThe space race between the U.S. and Russia began in the late 1950s as an outgrowth of the Cold War. One result of the 1957 launch of Sputnik I by the Soviet Union was the sparking on an interest in lunar geology by Arnold Mason of the Military Geology Branch of the U.S. Geological Survey. Using earth-based telescopic imagery, Arnold and colleagues would devote two years to producing the three landmark maps of the moon included in the Engineer Special Study of the Surface of the Moon. The three maps are:* Generalized Photogeologic Map (Sheet 1) – "the first major lunar map to show stratigraphic relationships: that is, it attempted to display the chronological order of the formation of the moon's surface features."* Lunar Rays (Sheet 2) – which "plotted the source craters and extent of the moon's most prominent ray systems " (ejecta from asteroid crashes on the moon's surface). * "Physiographic Divisions of the Moon (Sheet 3) – which "applied… Ler mais

Washington, D.C.: Army Map Service, Corps of Engineers, 1960. 1st Edition. No Binding. Very Good. 1st Edition. No Binding. 1 folding map, 1440 x 975 mm, image size 1275 x 940 mm. Light yellowing of paper, some paper thinness on old folds, but generally in a very good condition. ---- VERY RARE FIRST EDITION. The Army Corps of Engineers published the first edition of Arnold Mason and Robert Hackman's four-sheet Engineer Special Study of the Surface of the Moon map set in July 1960. The USGS published a second edition with "minor revisions" in 1961. "Even after the creation of NASA, the Army and USAF studied lunar surface bases ... The USAF also began lunar mapping using Earth-based telescopes. The first attempt to map lunar features for scientific and engineering purposes did not, however, originate within the Defense Department. It was begun instead by Arnold Mason of the U.S. Geological Survey (USGS) Military Geology Branch in Washington, DC. ... Early in 1959 - soon after… Ler mais
