Professor Arvidson is the deputy project scientist for NASA's Mars Exploration Rover mission, a member of the Mars Science Laboratory and Mars Reconnaissance Orbiter mission science teams, and the director of the Geosciences Node of NASA’s Planetary Data System.

Professor Arvidson directs the Earth and Planetary Remote Sensing Laboratory (EPRSL) in Rudolph Hall 281. The EPRSL is involved in many aspects of NASA's planetary exploration program, including developing science objectives and plans for missions, participating in mission operations and data analysis, and archiving and distributing data relevant to planetary surfaces and interiors. Arvidson and laboratory personnel have been or are currently involved in these NASA missions: Mars Viking Landers, Magellan Venus Orbiter, Mars Global Surveyor, Mars Odyssey, Mars Exploration Rovers (Spirit and Opportunity), Mars Phoenix Lander, Mars Reconnaissance Orbiter, Mars Science Laboratory (Curiosity rover), and the European Space Agency's Mars Express Orbiter. They have also collaborated with colleagues at the Jet Propulsion Laboratory to test prototype Mars rovers and other systems in Earth's deserts and volcanoes.

 

The Laboratory is the site of the Geosciences Node of NASA's Planetary Data System, working with planetary missions and individual scientists to create and distribute high-quality science data archives.

Research by laboratory staff, graduate students, and undergraduates currently focuses primarily on analyses of spaceborne observations of Mars, particularly to understand how the planet has evolved and the extent to which it was habitable. The unraveling of geological processes and defining geochemical cycles of possible biological relevance form the core of the research. The work is supported by key field work in terrestrial analog sites and close cooperation with experts in other fields of research such as Professor Jeffrey Catalano's work on aqueous geochemistry and Adjunct Professor Richard Morris' work on ferrous silicate and iron oxide spectroscopy.
