1966 USGS Geologic Map of the Moon: Mare Serenitatis Region


Price: $400.00


Title:    Geologic Map of the Mare Serentatis Region of the Moon by M. H. Carr.

Description:    A stunning full color geologic map of the Moon’s Mare Serenitatis, or ‘Sea of Serenity’ - better known to us as the ‘right eye’ of the Man in the Moon. The map's ghostly purple, punctuated by small, regular impact craters lends the map an eerily alien, worldly silence. Includes a sectional view of the mare from Montes Haemus to Posidonius (from the side), detailed text on the formation of the area's geology, extremely detailed ‘metadata’ explanating the mapmaking methodologies and symbols employed, and an index map showing the area’s location on the Moon.

This map represents a breath-taking leap forward not only in selenography (the study of the moon), begun in the late 1400s, but also in the record of humankind's fearless exploration of the world(s) around and beyond us.

The Mare Serenitatis is a lunar mare, or large, dark basaltic plain, formed by ancient volcanic eruptions. It is bordered by Mare Imbrium, Mare Tranquillitatis, and Mare Vaporum. These dark spots were dubbed maria, or ‘seas’, by early astronomers who mistook them for actual seas. These iron-rich plains are less reflective than the ‘highlands’ and thus appear dark to the naked eye. Mare Serenitatis is not only one of the lunar maria but also a mascon, or area of massive gravitational attraction. Both Luna 21 and Apollo 17 landed near the Mare Serenitatis.

It is believed that most of the moon’s craters were formed approximately 3.9 billion years ago, during a period of intense bombardment in the Inner Solar System. The cratering rate fluctuates as collisions in the asteroid belt send fragment clusters into the Inner Solar System. This map might show hypervelocity impact craters caused by the same cluster of asteroids that, 65 million years ago, caused the extinction of the dinosaurs.

As humans wouldn't land on the moon until 1969, how were we able to map its geology? The map’s extraordinarily detailed metadata explains that the cartographers used photos dating back to 1960 (remember the series of Ranger missions in the mid-60’s?), with relief created by measuring shadows, combined with an assumed sun angle and an assumed base elevation. The geology was arrived at from observing differences in, and layering of topographical forms, and in varying albedo (amount of reflected sunlight), both of which indicate different underlying materials formed under different processes. Goals of this work included the identification of suitable moon landing locations, and sources of oxygen for possible in establishing a more permanent lunar base.

This map would be a great companion piece to the other maps in the Geologic Atlas of the Moon, especially those forming the face of the Man in the Moon. It would also wonderfully complement early explorers’ maps, or any of the plates from Burritt’s famous 1856 Atlas to Illustrate the Geography of the Heavens , one of writer H.P. Lovecraft's most prized possessions.

Created by M.H. Carr and published as plate I-489 in the United States Geological Survey’s Geological Atlas of the Moon.

Cartographer:    The Office of the Coast Survey (later the U.S. Geodetic Survey), founded in 1807 by President Thomas Jefferson and Secretary of Commerce Albert Gallatin, is the oldest scientific organization in the U.S. Federal Government. Jefferson created the "Survey of the Coast," as it was then called, in response to a need for accurate navigational charts of the new nation's coasts and harbors. The first superintendent of the Coast Survey was Swiss immigrant and West Point mathematics professor Ferdinand Hassler. Under the direction of Hassler, from 1816 to 1843, the ideological and scientific foundations for the Coast Survey were established. Hassler, and the Coast Survey under him developed a reputation for uncompromising dedication to the principles of accuracy and excellence. Hassler lead the Coast Survey until his death in 1843, at which time Alexander Dallas Bache, a great-grandson of Benjamin Franklin, took the helm. Under the leadership A. D. Bache, the Coast Survey did most of its most important work. During his Superintendence, from 1843 to 1865, Bache was steadfast advocate of American science and navigation and in fact founded the American Academy of Sciences. Bache was succeeded by Benjamin Pierce who ran the Survey from 1867 to 1874. Pierce was in turn succeeded by Carlile Pollock Patterson who was Superintendent from 1874 to 1881. In 1878, under Patterson's superintendence, the U.S. Coast Survey was reorganized as the U.S. Coast and Geodetic Survey (C & GS or USGS) to accommodate topographic as well as nautical surveys. Today the Coast Survey is part of the National Oceanic and Atmospheric Administration or NOAA. Click here for a list of rare maps from The United States Coast Survey.
