Prior to joining the University of Arizona, Lewis taught space sciences and cosmochemistry at the Massachusetts Institute of Technology. An expert on the composition and chemistry of asteroids and comets, Lewis has written such popular science books as Rain of Iron and Ice and Mining the Sky: Untold Riches from the Asteroids, Comets, and Planets. Lewis is a frequent commentator on the Chinese network CCTV when China broadcasts its major missions live. He was a member of the Board of Directors of American Rocket Company and is currently Chief Scientist at Deep Space Industries. Raised a Presbyterian, Lewis became a Mormon, in 1980.
