Ashwin R. Vasavada
MSL Deputy Project Scientist

JPL Research Scientist


Education
  • B. S. in Geophysics and Space Physics, University of California, Los Angeles (1992)
  • Ph.D. in Planetary Science, California Institute of Technology (1998)

Research Interests
  • Geologic studies of Mars with regard to surface properties, volatiles, and climate history
  • Atmospheric dynamics, vertical structure, lightning, and aurora on Jupiter and Saturn
  • Stability and distribution of polar volatiles on Mercury and the Moon

Projects

MSL - Mars Science Laboratory Icon MSL - Mars Science Laboratory
The Mars Science Laboratory (MSL) mission is scheduled to land a rover on Mars in 2012, with the goal of assessing the past and present habitability of the area it explores on Mars.

LRO - Lunar Reconnaissance Orbiter Icon LRO - Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) launched in June 2009 with the objectives of finding safe lunar landing sites, locate potential resources, characterize the radiation environment, and demonstrate new technology.


Professional Experience
  • Deputy Project Scientist, Mars Science Laboratory
  • Co-Investigator, Lunar Reconnaissance Orbiter Diviner Radiometer (2004-present)
  • Committee on Public Affairs, American Geophysical Union (2006-2008)
  • University of California, Los Angeles - W. W. Rubey Faculty Fellow (2002-2004)
  • U.S. Congress - AAAS Science and Technology Policy Fellow (2001-2002)
