Description
This is a beautiful example of the U. S. Geological Survey's 1990 map of the Bach Quadrangle of the planet Mercury. This geologic map, based on the images from Mariner 10, depicts half of the Bach region - the other half being beyond the terminator during the three Mariner 10 encounters. Detailed notes and descriptions of map units are included on the right half of the sheet.
The Mariner 10, launched in November 1973, was on a flyby mission to study the atmosphere, surface and physical characteristics of the planet Mercury. It was also assigned to explore the planet Venus. The Mariner 10 was not only the first spacecraft to visit the planet Mercury, it also was the first to make multiple flybys of any planet (it had three encounters with Mercury as it looped around the Sun). Contact with the Mariner 10 ceased in March 1975, though it is still believed to be orbiting the Sun.
This map is created by Robert G. Strom, Michael C. Malin and Martha A. Leake in 1990 for the National Aeronautics and Space Administration and published by the U.S. Geological Survey as Atlas of Mercury Geologic Series map I-2015.

Cartographer
The Office of the Coast Survey (later the U.S. Geodetic Survey) (1807 - present), 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. More by this mapmaker...
