Executive Producer of Cosmos: Possible Worlds, and author of the companion book
After four years of planning, building and testing, Cosmos 1, the first solar sail spacecraft, is ready for Earth orbit. We cover the Nov. 9 press conference with Planetary Society Executive Director Lou Friedman and Ann Druyan, widow of Carl Sagan. Apollo 11 astronaut Buzz Aldrin adds his thoughts in a special interview. Emily has a real Q&A cliffhanger, and Bruce joins the solar sail party with a new What's Up trivia contest.
