Dr. Peter James
Dr. Peter James is a planetary geophysicist and a Urey Fellow at the Lunar and Planetary Institute. He investigates the surfaces and interiors of the rocky planets and moons in our solar system using a combination of spacecraft observations and modeling. Recent work by Dr. James utilizes gravity and topography data to characterize the geographic distribution of crustal thickness, mantle plumes, porosity, and mineral composition on Mercury, the Moon, Venus, and Europa. He participates on the science team of the Gravity Recovery And Interior Laboratory mission (GRAIL), which precisely measured the slight changes in gravitational acceleration around the Moon. Other mission involvement includes the Lunar Orbiter Laser Altimeter (LOLA) as well as the MErcury Surface, Space ENvironment, GEochemistry, and Ranging mission (MESSENGER), the first mission to orbit our solar system's innermost planet.
