Extraterrestrial Geology and Geophysics

This group is lead by Gunther Kletetschka. We are interested in meteorites, planetary geology, composition of asteroids and comets. Specifically we dwell into the comet age evaluation based on crystallinity, if asteroids can possess their own magnetic dynamo, and what is the nature of geophysical fields on planets like Mars, Jupiter, Mercury, including some of their moons. Growing interest is about fall of meteorites on our planet, and what change this makes to terrestrial environment. We explore possible ways how to design mining of asteroids, how to navigates this cargo back to Earth and how to safely deliver it to the surface of Moon or Earth. Part of our interest is understanding of the degree of terrestrial conditions influence on the pristine meteorite's composition once it lands.
