The international Mars exploration program has been guided by a remarkably useful framework that describes how the environmental conditions of Mars have evolved. Built on the basis of observations by instruments on the European Space Agency’s Mars Express Orbiter, this framework describes an early era of Earth-like surface environments that gave way to a far more arid environment in which surface water was acidic and salt-rich. Ongoing observations by high-resolution instruments have continued to refine and extend our knowledge, however, as is the case on Earth, the greatest insight comes from close-up examination of the sedimentary rock record, which indicates that interactions between iron-rich waters and the atmosphere have played a critical role in the evolution of the Martian surface. Dr. Hurowitz will discuss those observations, as well as the upcoming Mars 2020 rover mission and the role that the Planetary Instrument X-ray Lithochemistry (PIXL), part of the scientific payload for that mission, will play in further deciphering the history of the surface & climate of Mars.

Dr. Joel A. Hurowitz is at the forefront of the exploration of Mars. He is a Deputy Principal Investigator on the Mars 2020 Rover PIXL instrument investigation and, on other missions, has served as scientist, rover instrument design & operations specialist, and science & engineering operations team leader. He's worked at NASA's Jet Propulsion Laboratory, CalTech, and is currently an assistant professor in the Department of Geosciences at Stony Brook University.
