Dr. Sarah Milkovich is a planetary geologist and a systems engineer at NASA’s Jet Propulsion Laboratory. Sarah works on spacecraft science operations, at the point where science and engineering meet. Sarah is currently the Investigation Scientist for the HiRISE (High Resolution Imaging Science Experiment) camera on Mars Reconnaissance Orbiter, where she represents the far-flung HiRISE science team to the JPL-based spacecraft management; keeps the lines of communication between scientists, instrument operators, and spacecraft engineers open; and works on spacecraft science operations. Sarah is also the science operations systems engineer for Mars Science Laboratory (the Curiosity rover), where she focuses on maintaining and improving the science planning process and supporting the science team as they plan the rover’s daily activities. She has won JPL and NASA team awards for her efforts to return the best possible science within spacecraft engineering constraints. Sarah received her B.S. in planetary science from Caltech, and her M. Sc. and Ph.D. from Brown University in planetary geology with studies of mountain glaciers and polar deposits on Mars, and volcanism on Mercury. Sarah joined NASA’s Jet Propulsion Laboratory in 2005 as a postdoctoral research fellow, studying martian ice deposits using images, radar, and topography. From childhood, she had dreamed of working on spacecraft, and was thrilled to be hired in 2008 as a science planning systems engineer. Sarah was a member of the surface operations team for Mars Phoenix during the summer of 2008, and the Cassini-Huygens Mission science planning team from 2008-2012. Sarah's scientific research continues to focus on the geological history of the polar deposits of Mars.
