                            New Horizons mission that successfully explored the Pluto system and is now exploring the Kuiper Belt; the farthest exploration 
                            in the history of humankind. In 2007 and 2008, Dr. Stern served as NASA's chief of all space and Earth science programs.
                            Dr. Stern's research has focused on studies of our solar system's Kuiper Belt and Oort Cloud, comets, the satellites of the outer 
                            planets, the Pluto system, and the search for evidence of solar systems around other stars. He is expected to fly several suborbital 
                            space missions aboard Virgin Galactic vehicles in 2019-2020.
                            Dr. Stern has published over 290 research papers and 40 popular articles. He is the author of two books, The U.S. Space Program 
                            After Challenger, and Pluto and Charon: Ice Worlds on the Ragged Edge of the Solar System. Additionally, he has served as editor 
                            on three research volumes, and three collections of scientific popularizations: Our Worlds, Our Universe, and Worlds Beyond. His 
                            latest book, Chasing New Horizons, was coauthored with David Grinspoon.
                            Since 2008, Dr. Stern has had his own aerospace consulting practice. In both 2007 and 2016, he was named to the Time 100 list.
