Planetary Science Institute ANNUAL REPORT 2009 PLANETARY SCIENCE INSTITUTE Th e Planetary Science Institute is a private, nonprofi t 501(c)(3) corporation dedicated to solar system exploration. It is headquartered in Tucson, Arizona, where it was founded in 1972. PSI scientists are involved in numerous NASA and international missions, the study of Mars and other planets, the moon, asteroids, comets, interplanetary dust, impact physics, the origin of the solar system, extra-solar planet formation, dynamics, the rise of life, and other areas of research. Th ey conduct fi eldwork in North America, South America, Australia, Asia and Africa. Th ey also are actively involved in science education and public outreach through school programs, teacher workshops, children’s books, popular science books and art. PSI scientists are based in 16 states, the United Kingdom, France, Switzerland, Russia and Australia with affi liates in China and Japan. Th e Planetary Science Institute corporate headquarters is located at 1700 E. Fort Lowell Road, Suite 106, Tucson, Arizona, 85719-2395. Th e main offi ce phone number is 520.622.6300, fax is 520.622.8060 and the Web address is www.psi.edu. PSI BOARD OF TRUSTEES Tim Hunter, M.D., Chair Brent A. Archinal, Ph.D. David H.

PSI Strengthens Science, Education and Support Staff PSI’s strength and advantage is in its people. Our culture of openness and high level of mutual support sets us apart from other organizations. In 2009 PSI continued to grow, adding 15 new staff , including 10 researchers. Other new personnel focus on Education and Public Outreach eff orts and add to PSI’s science support and administrative eff orts. New PSI staff members for 2009: Alice Baldridge Susan Benecchi Jade C.

PSI has been part of NASA’s Planetary Data System (PDS) eff ort to preserve, organize, and make mission data available to the scientifi c community since the PDS was formed in the early 1990s. Th e fi ve-year grant will fund PSI work on the Asteroid/ Dust Subnode of the PDS Small Bodies Node. PSI Senior Scientist Donald R. Davis is the Principal Investigator on the project. “NASA established PDS as a long-term archive for data col- lected on planetary missions,” Davis said.
