Mars on Ice: Dynamic Processes on the Cold Martian Surface
The High Resolution Imaging Science Experiment (HiRISE) camera has provided a flood of data showing the surface of Mars in unprecedented detail. Despite being cold and dry, Mars is a dynamic world that continues to evolve. With HiRISE, we have been able not only to observe fine details of the surface but also to see it change: new deposits appear in gullies, boulders move down slopes, and new impact craters dig into the ground and excavate ice. From these changes we can learn about both seasonal events and the slower processes that shape the underground ice. I will discuss results from the HiRISE camera and our present knowledge of the Martian surface, focusing these recent changes and their implications.
Dr. Colin Dundas is a postdoctoral research associate at The University of Arizona. He earned his Ph.D. at the Lunar and Planetary Laboratory in 2009, working with Professor Alfred McEwen. His research focuses on surface processes on Mars, primarily using data from the HiRISE camera; topics of interest include impact cratering, seasonal activity and Martian ground ice. His recent projects include investigation of new craters that have excavated subsurface ice and studies of recent, ongoing activity in Martian gullies.
This talk is free and open to the public. Doors open at 6:30 pm.
