NEWS NOTES ON SUSTAINABLE WATER RESOURCES Astrogeology and Planetary Geology https://en.wikipedia.org/wiki/Planetary_geology“Planetary geology, alternatively known as astrogeology or exogeology , is a planetary science discipline concerned with the geology of the celestial bodies such as the planets and their moons, asteroids, comets, and meteorites.[1][2] Although the geo- prefix typically indicates topics of or relating to Earth, planetary geology is named as such for historical and convenience reasons; due to the types of investigations involved, it is closely linked with Earth-based geology. Planetary geology includes such topics as determining the internal structure of the terrestrial planets, and also looks at planetary volcanism and surface processes such as impact craters, fluvial and aeolian processes. The structures of the giant planets and their moons are also examined, as is the make-up of the minor bodies of the Solar System, such as asteroids, the Kuiper Belt, and comets.”“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.”“The USGS Astrogeology Science Center in Flagstaff, Arizona has a rich history of participation in space exploration and planetary mapping, starting in 1963 when the Flagstaff Science Center was established to provide lunar geologic mapping and assist in training astronauts destined for the Moon. The USGS Astrogeology Science Center is a national resource for the integration of planetary geoscience, cartography, and remote sensing. As explorers and surveyors, with a unique heritage of proven expertise and international leadership, we enable the ongoing successful investigation of the Solar System for humankind.” More information about the USGS program can be found here: https://www.usgs.gov/centers/astrogeology-science-center ;
