Astrogeology Science Center


The USGS performs research that includes studies on geology, volcanism, astrobiology, dunes, ice and water flow, crater aging, mineral deposits and the make-up of various planetary surfaces. The team's primary focus is explaining geological and geophysical processes on the rocky planets and satellites. Such research leads to a better understanding of the character of our neighboring planets, the origins of the solar system, and a better comprehension of our own planet, Earth.

Revisiting Lava Flow Simple Models

Simple models relating the final dimensions of a lava flow to eruption parameters an lava rheology were used extensively in the 1980's but have fallen out of use in the terrestrial vocanology community. However, in the planetary volcanology community these models have had a resurgence of utilization, especially in response to the availability of high resolution topographic...

Planetary Caves

As USGS scientist and planetary cave enthusiast, Glen Cushing, points out, "Caves are important to the future of planetary exploration because they are believed to provide shelter from a range of harsh surface conditions, maintaining near-pristine surfaces and relatively stable microclimates."
