Marc D Rayman is the Dawn chief engineer and mission director at JPL. A lifelong space enthusiast, he began writing to NASA when he was nine years old, and joined JPL after receiving his PhD in physics a few years later. He has worked on a wide variety of astrophysics and planetary missions but, of course, nothing else as cool as Dawn. A very popular speaker and writer, he enjoys sharing the thrill of exploration and the rewards of scientific insight with the public.
