	Geology - Wikipedia, the free encyclopedia
		Planetary geology (sometimes known as Astrogeology) refers to the application of geologic principles to other bodies of the solar system.
		The word "geology" was first used by Jean-André Deluc in the year 1778 and introduced as a fixed term by Horace-Bénédict de Saussure in the year 1779.
		In geology, when an igneous intrusion cuts across a formation of sedimentary rock, it can be determined that the igneous intrusion is younger than the sedimentary rock.

	Planetary geology - Wikipedia, the free encyclopedia
		Planetary geologist and NASA astronaut Harrison "Jack" Schmitt collecting lunar samples during the Apollo 17 mission
		Planetary geology is a planetary science discipline concerned with the geology of the celestial bodies such as the planets and their moons, asteroids, comets, and meteorites.
		The study of rocks originated with studying rocks on Earth, and due to the types of investigations involved, planetary geology is closely linked with Earth-based geology.

	Planetary Geology Group - Welcome! (Site not responding. Last check: 2007-10-31)
		Planetary Geology is the study of the origin, evolution, and distribution of matter condensed in the form of planets, satellites, comets and asteroids.
		The approach used at Arizona State University in solving planetary geology problems incorporates results from spacecraft data analyses, laboratory simulations of various planetary processes, and field studies of features on Earth analogous to extraterrestrial features.
		The Planetary Geology Group is active in many different fields of Geology and in particular, Planetary Geology.

	CHAPTER 5: PLANETARY GEOLOGY: Manual of Remote Sensing
		Planetary geology is the study of surface and interior processes on solid objects in the solar system: planets, satellites, asteroids, comets, and rings.
		Planetary geology includes an assessment of the past state of the solar system, for example as preserved in the ancient, scarred surfaces of objects like the Moon and asteroids, or in the enigmatic polar layered deposits on Mars.
		Geologic histories of planetary surfaces are often documented in the form of geologic maps (compiled at various scales dependent on the available data and detail to be illustrated) which portray the three-dimensional surface units that comprise a planetary surface and indicate their relative stratigraphic positions.

	Planetary Geology
		More broadly, however, geology includes the study of all the worlds in our solar system: how planets and their satellites are born and how they evolve.
		Because a planet's geology is inextricably linked to such basic attributes as its size, density, distance from the Sun, and period of rotation, facts about these attributes are also included.
		Planetary geology can also give students insight into the scientific method, by showing how researchers are able to infer from raw data a great deal of information about a planet's characteristics and geology.

	Space and Planetary Geology: World of Earth Science
		Space and planetary geology comprises that branch of the discipline of geology that applies basic scientific principles to the study of the origin, development, and characteristics of solar system objects such as planets, satellites, asteroids, comets, meteorites, and interplanetary dust particles.
		On Earth, space and planetary geology investigations are generally limited to impact craters and impact effects upon Earth, and to the study of Earth as an analogue for other planets and their processes.
		Space and planetary geology has it origins in telescopic observations of planets, satellites, and comets and in the study of meteorites.

	USGS Astrogeology: Planetary Geologic Mapping Home Page
		Geologic mapping investigations of any imaged planetary body (except Earth) are proposed to NASA's Planetary Geology and Geophysics Program on an annual basis (generally due sometime between late April and early June) and then reviewed by the Lunar and Planetary Geoscience Review Panel.
		Two primary programs underway now are the systematic mapping of Venus at 1:5,000,000 scale using Magellan SAR data and local (1:500,000) to regional (1:5,000,000) scale mapping of Mars based on medium- to high-resolution Viking images.
		Geologic maps can be produced from existing map bases that are part of established map series (see the Index of Planetary Maps, 1992 or additions since 1992) or ones specifically generated for the geologic map.

	Planetary Geology for Teachers Home Page
		Planetary Geology for Teachers is an upper level undergraduate or graduate level course for K-12 teachers and physical science majors who wish to continue their education in planetary science or to pursue a Master of Natural Science degree.
		Many topics will be covered, but the course will focus on planetary evolution and differentiation, exploration of the solar system, NASA planetary missions, volcanic activity, atmospheres, geology of our nearest neighbors (Moon, Mars and Venus), surficial processes, and plate tectonics.
		Introductory geology courses from other departments or institutions may be substituted,but students need to check with the instructor.

	Abstracts for the Planetary Geology & Geophysics Program
		Most planetary surfaces in the solar system are shaped by multiple impacts and a quantitative understanding of the damaged zone around the craters is key to interpreting meteorite damage, regolith growth, and impact energy deposition.
		It is proposed to continue to pursue the general objectives of developing models for the interaction of electromagnetic radiation with planetary regoliths, verifying and refining these models by laboratory measurements, and investigating the natures and compositions of planetary surfaces and processes by applying these models to quantitative analysis of remotely-sensed planetary data.
		Two important goals of our experimental investigation of the rheology of planetary materials are (a) to determine flow laws describing their creep behavior over wide ranges of temperature, stress and strain rate and (b) to develop an understanding of the physical mechanisms by which these rocks flow.

	A month until LPSC - The Planetary Society Blog \| The Planetary Society
		LPSC is particularly focused on planetary geology, so you won't see much in the way of astronomy or giant planet atmospheres and magnetic fields stuff, but that leaves plenty of room for session after session on the surfaces of the terrestrial planets, icy moons, and little rocky bodies that populate the solar system.
		Unlike the Division of Planetary Sciences meeting that I attended last year (click here to read all my blog entries from that run together), which had only two concurrent sessions to choose from, LPSC always runs four at once, which leads to some tough choices.
