Mars Atmosphere and Climate: Past, Present, and Future
Prof. Bruce M. Jakosky
NASA MAVEN’s Principal Investigator
Professor of Geological Sciences
Associate Director for Science
Laboratory for Atmospheric and Space Physics
University of Colorado
Geological and geochemical evidence points toward Mars having had a warmer and wetter climate early in its history, in which liquid water could flow and was abundant. This compares to today’s very cold and dry that cannot support stable water. What caused this change in climate? Where did the water go? Where did the CO2 from an early greenhouse atmosphere go? And is it possible to mobilize CO2 remaining on the planet back into the atmosphere and “terraform” Mars to make a more clement climate? I’ll discuss the evolution of the Martian atmosphere and climate, integrating results from numerous recent spacecraft missions.
Dr. Jakosky is a Professor in the Laboratory for Atmospheric and Space Physics and the Dept. of Geological Sciences at the University of Colorado in Boulder, and is Associate Director for Science at LASP. He received his Ph.D. in Planetary Science and Geophysics from Caltech in 1982. His research interests are in the geology of planetary surfaces, the evolution of the Martian atmosphere and climate, the potential for life on Mars and elsewhere, and the philosophical and societal issues in astrobiology. He is the Principal Investigator of the Mars Atmosphere and Volatile Evolution (MAVEN) mission to Mars that has been orbiting Mars since fall of 2014. He has published more than 300 papers in the refereed scientific literature, and has authored or co-authored a number of books, including “The Search for Life on Other Planets” and “Science, Society, and the Search for Life in the Universe”.
