David Kass

  • B.S. in Computer Science and Mathematics - University of Dayton (1992)
  • Ph.D. in Planetary Science - California Institute of Technology, (1999)

Research Interests
  • Mesoscale/weather data analysis, modeling and forcasting of the martian atmosphere
  • Orbital/surface observations of the martian atmosphere and data assimilation of such observations
  • Long term (4.5 Gyr)evolution/climate change of the martian atmosphere (composition, dynamics and transport)


MRO - Mars Reconnaissance Orbiter Icon MRO - Mars Reconnaissance Orbiter
NASA's Mars Reconnaissance Orbiter (MRO) launched in 2005 and is on a search for evidence that water persisted on the surface of Mars for a long period of time.

MSL - Mars Science Laboratory Icon MSL - Mars Science Laboratory

The Curiosity rover landed at Gale Crater on August 5, 2012. It is designed to search for and assess past or present habitable environments, i.e., those capable of supporting microbial life.

Mars 2020 Icon Mars 2020
NASA's Mars 2020 mission will build upon many discoveries from the Curiosity Mars rover and the two Mars Exploration Rovers, Spirit and Opportunity by taking the next key steps in our understanding of Mars' potential as a habitat for past or present life.

InSight Icon InSight
InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) is a NASA Discovery Program mission that will place a single geophysical lander on Mars to study its deep interior.
