Volume 30, Number 1 April 2012

Message from the Chair invited speakers at the 30th anniversary special session, “Then and Now: The Past 30 Years of Exploration,” who amazed us with a fascinating retrospective on the exploration of the solid , our , the outer solar system icy , and the .

At a time when future federal funding for

As the 2011-2012 Chair of the federal budget – more than any other science Planetary Geology Division, I would like to program), we should constantly remind start off by thanking the PGD membership ourselves about how far we have come in for your continued support of the division. the planetary sciences in so short a time. In We celebrated the 30th anniversary of the the past half-century, our young field of PGD during 2011 with a record 620 science has made great scientific advances, members, and thoroughly enjoyed our engaging humankind with visions of a interactions with you at the annual meeting stunningly diverse solar system.

ANNOUNCING THE 2012 G.K. GILBERT AWARD WINNER

Dr. Peter Schultz, Brown University

Previous Gilbert Award Recipients: E. Shoemaker (1983); G. Wetherill (1984); W. Alvarez (1985); R. Baldwin (1986); D. Gault (1987); D. Wilhelms (1988); H. Schmitt (1989); H. Masursky (1990); J. Guest (1991); J. Wood (1992); M. Carr (1993); S. R. Taylor (1994); B. Lucchitta, 1995); R. Sharp (1996); R. Greeley (1997); J. Adams (1998); S. Solomon (1999); L. Soderblom (2000); H. J. Melosh (2001); J. Head (2002); R. Phillips (2003), W. Hartmann (2004), L. Wilson (2005), M. Gaffey (2006), M. Zuber (2007), P. Christensen (2008), R. Strom (2009), C. Pieters (2010), S. Squyres (2011).

The 2012 G.K. Gilbert awardee is Dr. Peter Schultz, Professor, Brown University.

Impact cratering is one of the few processes affecting all planetary bodies. Records can provide clues for contrasting geologic evolutions. The planetary record, lab experiments, field studies, and theoretical approaches allow exploring a process at scales we hope we never witness. Dr. Schultz’s main research has been on the effect of impact angle on cratering and the role of the atmosphere in modifying the process. Different planetary environments, laboratory simulations, and theoretical models allow testing under extreme conditions and to extreme scales.

Peter H. Schultz received his Ph.D. in Astronomy at the University of Texas at Austin in 1972. After working as a research associate at the NASA Ames Research Center, and a Staff at The Lunar and Planetary Institute, he became an Associate Professor in the Department of Geological Sciences at Brown University in 1984. He was promoted to full Professor in 1994. In addition to his research and teaching responsibilities at Brown, Pete has served as Director of the Lunar and Planetary Institute Planetary Image Facility, and is currently the Director for both the Northeast Planetary Data Center and the NASA/Rhode Island University Space Grant Consortium.

9 Upcoming 2012 Annual Meeting

The 2012 GSA annual meeting will be held November 4-7, 2012, in Charlotte, North Carolina (http://www.geosociety.org/meetings/2012/). The theme of the meeting is Geosciences: Investing in the Future. We hope to have a very visible presence at the meeting. The final list of sessions approved by GSA will be reported in the Fall 2012 PGD Newsletter, which will be published prior to the Annual Meeting. Note that we especially encourage students to submit abstracts to any of these sessions!

List of Proposed Sessions, 2012 GSA Annual Meeting, Charlotte

Pardee Session: Mars Rover Curiosity: Geoscience in Gale Crater, GSA Planetary Geology Division, Robert C. Anderson - The Mars Science Laboratory mission is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the red . Launched on Nov. 26, 2011, the Mars Science Laboratory rover, Curiosity, will be used to assess whether Mars ever was, or is still today, an environment able to support microbial life. In other words, its mission is to determine the planet's "habitability." To answer this question, the rover carries the most advanced suite of instruments ever sent to the martian surface. The rover is designed to analyze multiple samples of rocks and soils and the local geologic setting in order to detect chemical building blocks of life (e.g., forms of carbon) and will assess what the Martian environment was like in the past. Assuming a successful landing of the Mars Science Laboratory on August 6, 2012, the timing of the annual meeting of the Geological Society of America in Charlotte corresponds to the first 90 days on the surface of Mars. This meeting will provide the first look by the science community at the science data and preliminary results from the field site in Gale Crater. (Planetary Geology)
