Planetary geology

Eugene Shoemaker is credited with bringing geologic principles to planetary mapping and creating the branch of planetary science in the early 1960s, the Astrogeology Research Program, within the United States Geological Survey. He made important contributions to the field and the study of impact craters, Selenography (study of the Moon), asteroids, and comets.[3]

Today many institutions are concerned with the study and communication of planetary sciences and planetary geology. The Visitor Center at Barringer Meteor Crater near Winslow, Arizona includes a museum of planetary geology. The Geological Society of America's Planetary Geology Division has been growing and thriving since May 1981 and has two mottos: "One planet just isn't enough!" and "“The GSA Division with the biggest field area!"

Major centers for planetary science research include the Lunar and Planetary Institute, the Applied Physics Laboratory, the Planetary Science Institute, the Jet Propulsion Laboratory, Southwest Research Institute, and Johnson Space Center. Additionally, several universities conduct extensive planetary science research, including Montana State University, Brown University, the University of Arizona, Caltech, the University of Colorado, Western Michigan University, MIT, and Washington University in St. Louis.

Several tools been used in planetary geology, including common archaeological tools such as hammers, shovels, brushes, etc. are often used by planetary geologists.[4] Along with these common tools, new advanced technologies are used by planetary geologists[5] Scientists also with these tools, use maps and images that telescopes on Earth (thirty meter telescope) and orbiting telescopes (Hubble) have taken different planetary bodies.[6] The maps and images are stored in the NASA Planetary Data System where tools such as the Planetary Image Atlas help to search for certain items such as geological features including: mountains, ravines, and craters.[7]

Planetary geology uses a wide variety of standardized descriptor names for features.[8] All planetary feature names recognized by the International Astronomical Union combine one of these names with a possibly unique identifying name. The conventions which decide the more precise name are dependent on which planetary body the feature is on, but the standard descriptors are in general common to all astronomical planetary bodies. Some names have a long history of historical usage, but new must be recognized by the IAU Working Group for Planetary System Nomenclature as features are mapped and described by new planetary missions.[9] This means that in some cases names may change as new imagery becomes available,[9] or in other cases widely adopted informal names changed in line with the rules.[10] The standard names are chosen to consciously avoid interpreting the underlying cause of the feature, but rather to describe only its appearance.[8]
