Erik Asphaug was born in 1961 in Oslo, Norway, to parents who had immigrated to California after the war. He grew up in various parts of the US, and then back in Norway for his teenage years. He majored in English and Math at Rice University, and then taught high school in Minneapolis and Tucson. He tried his hand at graduate studies at the University of Arizona, and has been a planetary scientist ever since. In 1998 he won the Urey Prize of the Division of Planetary Sciences of the American Astronomical Society, and asteroid 7939 Asphaug recognizes his work on comet physics and impacts. He helped start the planetary sciences program at the University of California, Santa Cruz, where he became a full professor in 2006, and then was Ronald Greeley Chair of Planetary Sciences at Arizona State University from 2012 to 2017. He's worked on spacecraft mission projects from Galileo to MMX. Now he's a professor at the University of Arizona, back in Tucson, and lives with his family in the foothills of the Santa Ritas.
