Dr. Michael Smith is an expert in the analysis of atmospheric observations and radiative transfer modeling, specializing in the development and use of algorithms for the retrieval of atmospheric parameters from spacecraft observations of Mars. Dr. Smith has participated on almost every mission to Mars since the early nineties including Mars Global Surveyor, Mars Odyssey, Spirit and Opportunity rovers, Mars Reconnaissance Orbiter, Curiosity rover, the Trace Gas Orbiter, the Emirates Mars Mission, and the Perseverance rover.

Dr. Geronimo Villanueva utilizes remote sensing and spectroscopy to search for astrobiology-relevant species on Mars, Venus, Ocean Worlds (Europa, Enceladus), primordial bodies (comets) and in distant exoplanets. Dr. Villanueva leads a widely used modeling tool called the Planetary Spectrum Generator (PSG,, and he is the Associate Director for Strategic Science of the Solar System Exploration Division at NASA-GSFC. He is also the co-lead Scientist of the Comet Interceptor MIRMIS instrument, Co-Investigator of the ExoMars/TGO mission, and leader for Mars and Ocean Worlds studies (GTO) for the James Webb Space Telescope (JWST).
