Life on Mars, Meteorites, and Extraterrestrial Mus
On Thursday, April 21, at Rothchild’s (8807 Kingston Pike), the Oak Ridge Chapter of ASM International will proudly present speaker Dr. Ed Vicenzi, from the Smithsonian National Museum of Natural History, discussing the topic "Life on Mars, Meteorite Studies, and Extraterrestrial Musings"

The evening will start with a social hour at 5:30 pm, a catered dinner at 6:30 pm, and the talk at 7:30 pm.

The cost is $25.
Students (graduate, undergraduate, high school, etc.) can attend for free as long as they RSVP (the cost is $10 for students, otherwise).
Season passes will be accepted.

You can find out more information and RSVP at the website www.korrnet.org/orcasm; you may also RSVP by calling Michael Lance at (865) 241-4536 or emailing Michael at lancem@ornl.gov. Please RSVP by this Friday, April 15.

Abstract: Roughly a century ago, speculation regarding the existence of life on Mars was fueled by the writings of Percival Lowell, who envisioned a dying race of extraterrestrials who had constructed a complex global irrigation system. In the latter half of the twentieth century, NASA missions Mariner and Viking dispelled this notion on the basis of flyby, orbital, and lander data. Mars was declared a dead planet. Then, in the summer of 1996, a group of NASA scientists claimed to have found traces of fossil life in a Martian meteorite. Their evidence and the current view of the scientific community on the veracity of these findings will be reviewed. More recently, data harvested from the European spacecraft Mars Express suggested methane, a short-lived gas, has a source near the surface of the red planet. This finding has sparked controversy over the role past/present life in this atmospheric anomaly. Speculation regarding whether life is likely to be abundant or rare in the universe will also be entertained.

Ed Vicenzi is a research geochemist and the Director of the Analytical Laboratories in the Smithsonian Institution’s Department of Mineral Sciences. He is actively involved with applying electron and ion microbeam methods to earth and planetary research. His current interests include mining information from combined time-of-flight–secondary-ion mass spectrometry, X-ray microanalysis, and cathodoluminescence datasets.

Before joining the Smithsonian National Museum of Natural History in 1999, he spent over six years at the Princeton Materials Institute. Prior to his time at Princeton University, he spent two years as a post-doc in Sydney using megavolt proton microbeams coupled with solid-state X-ray detectors to obtain trace element analysis. He received his BSc from McGill University, his Masters from the University of Oregon, and his PhD from Rensselaer Polytechnic Institute— all in Earth Sciences.
