  • Title: Robotic Martians: Orbiters, Landers, Rovers and a Half Century of Unmanned Exploration
    Speaker: Christopher S. Edwards
    Associate Professor of Planetary Science
    Northern Arizona University, AZ

    Abstract: Humans have sent an armada of robotic explorers to Mars over the past several decades. These spacecraft have enabled countless scientific discoveries and revealed Mars a complex planetary body much like our own Earth. For example these spacecraft have revealed ancient aqueous processes on Mars, which have been explored in detail from orbit but also via landed platforms such as rovers. However getting to Mars is not without significant risk. Nearly half of all spacecraft never make it. In this talk, we’ll examine some of the recent findings by NASA missions, discuss some upcoming missions launched this summer and review some of the challenges of sending spacecraft to Mars, into orbit, and onto the surface.


    Biography: Christopher S. Edwards is an Associate Professor of Planetary Science at Northern Arizona University. He is a science team member and instrument scientist for the Emirates Mars Infrared Spectrometer on the Emirates Mars Mission “Hope”, a participating scientist on the Mars Science Laboratory Curiosity Rover, a participating scientist on the OSIRIS-Rex mission to Bennu, a Co-Investigator on the Lunar Trailblazer mission and has worked on numerous other Mars missions including the 2001 Mars Odyssey Thermal Emission Imaging System, Mars Global Surveyor Thermal Emission Spectrometer, and the Mars Reconnaissance Orbiter Compact Reconnaissance Imaging Spectrometer for Mars. Edwards participated on these science and instrument teams while perusing his Ph.D. at Arizona State University, as the Planetary Science Postdoctoral Fellow at the California Institute of Technology, as a Research Scientist at the U.S. Geological Survey Astrogeology Science Center and now at NAU. His research focuses on the composition, physical properties and processes, and morphology of planetary surfaces, with an emphasis on rocky bodies including the Earth. A major element of his research has been the design and development of infrared remote sensing instruments for use in space, the laboratory and for fieldwork. His research uses infrared spectroscopy, radiometry, laboratory spectroscopic measurements, geologic field observations, and numerical modeling, and has taken him to field sites in the western U.S., Yellowstone, Hawaii, and Spain, as well as the Himalayan mountains of Bhutan.
