Overview

Jim Bell is Professor at the Cornell University Astronomy Department's Center for Radiophysics and Space Research; he also has a Graduate Field appointment in Geology. He received his Ph.D. from the University of Hawaii in 1992, performing research on Mars surface mineralogy and climate variations using infrared and optical telescopes at Mauna Kea Observatory. He was a National Research Council postdoctoral research fellow at NASA's Ames Research Center prior to coming to Cornell. His studies primarily focus on the physical, compositional and mineralogic properties of planetary surfaces, asteroids, and comets using data obtained from telescopes and spacecraft missions. He has been a member of the Science Teams of the NASA Mars Pathfinder, Near Earth Asteroid Rendezvous (NEAR), Comet Nucleus Tour (CONTOUR), Mars Odyssey Orbiter, Mars Reconnaissance Orbiter, Lunar Reconnaissance Orbiter, and Mars Science Laboratory rover missions, and is the Payload Element Lead for the Pancam color cameras on the Mars Exploration Rovers Spirit and Opportunity. He has also been a Principal Investigator (PI) in the NASA Mars Data Analysis and Planetary Geology and Geophysics Programs. In addition, he is carrying out laboratory and field studies of the spectroscopic properties of rocks and soils that are analogs to planetary surface materials.

Bell has published many of his research results in major astronomy journals, and in 2008 edited The Martian Surface: Composition, Mineralogy and Physical Properties (Cambridge U. Press). He is an Editor for Icarus, and a reviewer for journals like Science, Nature, and J. Geophys. Res. In addition to frequent contributions to popular astronomy magazines and radio shows, he has written or edited four popular-level books: Asteroid Rendezvous, about the NEAR mission; Postcards from Mars and Mars 3-D, a photography book about the Mars rover missions, and Moon 3-D, a photography book about lunar exploration.

In recent years, Jim has taught Astronomy 3310 (Planetary Image Processing), Astronomy 2202 (Our Solar System), Astronomy 4410 (Experimental Astronomy), and Astronomy 6577/EAS 5770 (Planetary Surface Processes). As a House Fellow in Becker House, he has also taught, with Prof. Cindy Hazan, the Dean of Becker House, a service learning class (Human Development 402).
