Pickled in Brine
Mars may once have been awash in water but the water was very salty
Oct. 26,
2009 -- Andrew H. Knoll, Ph.D., Fisher Professor of Natural History and professor of earth and planetary sciences at Harvard University, will discuss the evidence for life on Mars at 7 p.m. Oct. 30 in Room 300, Laboratory Sciences Building, on the Danforth Campus of Washington University in St. Louis.

Cloudy with a chance of pebble showers
Simulation suggests rocky exoplanet has bizarre atmosphere
Sept. 29,
2009 --
Intrigued by the discovery last February of Corot-7b, a rocky exoplanet, Washington University in St. Louis scientists set out to investigate its atmosphere the only way so-far possible: mathematically and by simulation. Tidally locked with its star and orbiting very close to it, the planet is hot enough to melt rock on its star-facing side. Its atmosphere consists of the components of silicate rocks in gaseous form and, the simulation suggests, periodically rains pebbles or grains of sand onto the molten surface below.

| Saturn's moon Enceladus, seen by the Cassini spacecraft. |
Data collected during two close flybys of Saturn's moon Enceladus by NASA's Cassini spacecraft add more fuel to the fire about the Saturnian ice world containing sub-surface liquid water, according to a report in the July 23 issue of the journal Nature that is co-authored by a planetary researcher from Washington University in St. Louis.

'Big Ideas'
What everyone should know about Earth sciences summarized in free NSF-funded e-booklet
June 5,
2009 --
If you're clueless about petrology, paleobiology and plate tectonics, the National Science Foundation and the Earth Science Literacy Initiative (ESLI) have just released a free pamphlet offering a concise primer on what all Americans should know about the Earth sciences. "The Earth Science Literacy framework document of 'Big Ideas' and supporting concepts was a community effort representing the current state-of-the-art research in Earth sciences," said Michael E. Wysession, Ph.D., chair of ESLI and associate professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis.

Putting a new spin on an old technique, Anne M. Hofmeister, Ph.D., research professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, has revolutionized scientists' understanding of heat transport in the Earth's crust, the outermost solid shell of our planet.

500-pound gorilla on the dais
Population growth puts dent in natural resources

| Criss |
It's a 500-pound gorilla that Robert Criss, Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, sees standing on the speaker's dais at political rallies, debates and campaigns. Its name is population growth. And sometime during President-elect Barack Obama's first several months in office, he will have to factor it into future environmental policy, says Criss."Population growth is driving all of our resource problems, including water and energy. The three are intertwined," Criss says. "The United States has over 305 million people of the 6.7 billion on the planet. We are dividing a finite resource pie among a growing number of people on Earth. We cannot expect to sustain exponential population growth matched by increased per capita use of water and energy. It's troubling. But politicians and religious leaders totally ignore the topic."

Seeking the oldest ice
Wiens heads seismology effort in international Antarctic study
Oct. 21,
2008 --
Douglas A. Wiens, Ph.D., professor and chair of earth and planetary sciences in Arts & Sciences, will head the seismology research team of an ambitious international effort to map and analyze an unknown part of Antarctica. The project is called AGAP (Antarctica's Gamburtsev Province) after the Gamburtsev Subglacial Mountains, which are the main feature of the region. Wiens, Patrick Shore, computer specialist in earth and planetary sciences, and graduate students David Heizel and Amanda Lough will install 26 seismographs on the frozen surface of central Antarctica, a part of the world that is a geological mystery.

Bringing Mars to life
Ray Arvidson to deliver inaugural Robert M. Walker Distinguished Lecture
Oct. 20,
2008 -- Raymond E. Arvidson, Ph.D., the James S. McDonnell Distinguished University Professor at Washington University, will deliver the inaugural Robert M. Walker Distinguished Lecture at 7 p.m. Oct. 30 in Room 100, Brown Hall, on the university's Danforth Campus. Arvidson, who has played key roles in NASA's missions to Mars, including the current Phoenix Mars Mission, will discuss "Mars: Environments, Habitability, and Life" during the free lecture that is open to the public.
