Charles Phillips is a Thermal Engineer in the Thermal and Propulsion Engineering Section at the Jet Propulsion Laboratory. He received his B.S. in Mechanical Engineering from the Rensselaer Polytechnic Institute and is currently working on a M.S in Astronautics at the University of Southern California. Charles has been working at JPL since 1997. His primarily emphasis had been working on Mars related flight projects since starting at JPL. For MER, Charles’s responsibilities included the thermal design, analytical thermal modeling, system-level test, and thermal operations of the MER rovers. Currently Charles works part-time on MER monitoring the rover’s thermal health and keeping a system-level thermal model correlated to flight telemetry. Charles has also started supporting a very challenging mission called SIM (Space Interferometry Mission) which is a proposed orbiting telescope designed to optically detect Earth-like planets around distant stars.
