Philip R. Christensen is a Regents Professor of geological sciences and the Ed and Helen Korrick Professor in the School of Earth and Space Exploration at Arizona State University. He completed his Ph.D. in Geophysics and Space Physics at UCLA in 1981. His research interests focus on the composition, physical properties and processes, and morphology of planetary surfaces, with an emphasis on Mars and the Earth.
A major element of his research has been the design and development of spacecraft infrared remote sensing instruments. Christensen is the Principal Investigator for the 2001 Mars Odyssey Thermal Emission Imaging System (THEMIS) instrument, and the Thermal Emission System (TES) instrument on Mars Global Surveyor. He is also a Co-Investigator on the Mars Exploration Rover missions, responsible for building and operating the Miniature Thermal Emission Spectrometer (Mini-TES) instruments. He is Principal Investigator for the OSIRIS-REx Thermal Emission Spectrometer (OTES) on NASA's OSIRIS-REx mission to asteroid Bennu (1999 RQ36). His research uses infrared spectroscopy, radiometry, laboratory spectroscopic measurements, field observations, and numerical modeling, and has taken him to field sites in the western U.S., Hawaii, Mexico, and South America.
Since the mid-1990's he has pursued the use of spacecraft observations to study environmental and urban development problems on Earth.
Christensen was awarded NASA's Exceptional Scientific Achievement Medal in 2003 for his pioneering scientific observations of Mars in the infrared, and was elected as a Fellow of the American Geophysical Union in 2004. He was awarded the NASA Public Service Medal in 2005, the Geological Society of America's G.K. Gilbert Award in 2008, and ASU's Eugene Shoemaker Memorial Award in 2011.
Weekly informal discussions of current topics in Mars exploration, including recent science discoveries, NASA exploration policy, and future plans for martian science and engineering missions.
Quantitative remote sensing of the Earth and planetary surfaces, with an emphasis on using the interaction of electromagnetic energy with matter to determine the physical properties of surfaces. Emission, absorption, reflection, transmission, and scattering of energy are developed and applied to visible, near-infrared, thermal, and radar observations.
Science and engineering of Earth, solar system, and space exploration. Experimental design, engineering design; teaming; the professions of science and engineering.
Geological evolution of Mars through analyses of spacecraft data, theoretical modeling, and study of terrestrial analogs; emphasizes current work. Possible field trips to examine Arizona geology.
Follow-on to the introductory Remote Sensing course, with an emphasis on advanced techniques and applications. Visble, near-IR, and infrared spectroscopy and radiometry methods are explored in detail.
