P8. When One Planet Isn't Enough: Celebrating 25 Years of Solar System Exploration

GSA Planetary Geology Division

The Planetary Geology Division is proud to be celebrating its 25th anniversary as a division of the Geological Society of America. If the 25 years prior to our inception represented the first great age of human exploration, then the years from 1981 to 2006 have represented an era in which scientific discovery — and most particularly geological discovery — has taken center stage. Some revelations were predicted; others were completely unexpected. Many continue to be enthusiastically and sometimes contentiously debated. All represent some of the most important, most current and active research in planetary geology today.
