Exploring Earth’s Attic: Treasures of the Cosmos

Tuesday, October 20, 2009 @ 7:00 PM-8:30 PM

Featured Speaker: Raymond E. Arvidson, Ph.D., James S. McDonnell Distinguished University Professor and Director, Remote Sensing Laboratory, Washington University in St. Louis, Department of Earth and Planetary Sciences; Fellow, Academy of Science – St. Louis and recipient 2006 Outstanding St. Louis Scientist Fellows Award

There are treasures to surpass those in grandma’s attic, surprising discoveries, and awesome finds amongst the heavenly bodies in this exhilarating talk on Treasure Hunting in the cosmos. The planetary sciences are among the most exciting of today’s rapidly changing scientific enterprises– yielding fascinating clues about the beginnings of our solar system and improving our understanding of Earth’s origin and evolution, its environments and suitability for life… it’s the 21st Century’s version of the Western frontier. You don’t want to miss this insider look at planetary exploration with Washington University’s Earth and Planetary Sciences Chair and NASA Mars Missions principal investigator, Raymond Arvidson, as he takes us on a treasure hunt that is out of this world.

Explore Venus where it rains sulfuric acid emitted from volcanoes, the atmosphere is predominantly carbon dioxide, and the planet’s surface temperatures are warmer than most ovens. Learn about Earth’s moon and its separation from early Earth, along with the possibility that water ice may be permanently trapped in lunar polar regions. Discover Mars and the evidence for ancient lakes and rivers and implications for the red planet’s environments and life.
