He has guest starred on many popular television series and starred as Commander Woolsey on Stargate Atlantis. Bob has appeared in over two dozen films, including the 2016 Coen brothers comedy, Hail Caesar.
Bob’s childhood passion for Biology helped forge his lifelong interest in science and exploration. Bob served for more than 15 years on the advisory board of The Planetary Society , a space advocacy nonprofit which was co-founded by Carl Sagan in 1980 and is presently led by Bill Nye. Tantalizing recent discoveries of water on Mars and the possibility of finding microbial life made the 1995 the invitation to join The Planetary Society Board auspicious and irresistible. Bob hopes to bring even more of the science fiction audience to the Planetary Society membership and hosts a free monthly video newsletter ( to subscribe, visit www.planetary.org ) called The Planetary Post. He believes, “Science fiction dreams the dream and helps pave the way for real science and exploration to fulfill that dream. If you love science fiction, you love exploration and you belong in The Planetary Society.”
