Undergraduate paves way for NASA Mars mission

Tabatha Heet, a junior earth and planetary sciences major and Pathfinder student, shows Ray Arvidson, earth and planetary sciences department chair, a potential landing site for the Phoenix mission to Mars.Earth and planetary scientists at Washington University in St. Louis are paving the way for a smooth landing on Mars for the Phoenix Mission scheduled to launch in August this year by making sure the set-down literally is not a rocky one. A team led by Raymond E. Arvidson, Ph.D., James S. McDonnell Distinguished University Professor in Arts & Sciences, has been analyzing images taken from a NASA instrument to make sure that the Phoenix spacecraft lands in a spot on the Red planet’s northern plains that is relatively rock-free. Video included.

Geologists map Cartwright Country

The Ponderosa gang. The “Big Bonanza” was part of the Comstock Lode, now newly mapped.Remember the burning Ponderosa map at the beginning of the long-running TV show “Bonanza”? It’s up in flames before you can read all the place names. Now a geologist at Washington University in St. Louis has replaced that map with one of the famous ore site known as the Comstock Lode, a part of which is the “Big Bonanza.” While it’s doubtful that Hoss, Adam and Little Joe – not to mention the sages, Pa and Hop Sing – could make heads nor tails of it, the map is a valuable contribution to geology because it gives an interpretation of the flow of hot waters interacting with rock some 14 million years ago that created the ore district.
