Principal Investigator Francis Everitt has been with the Gravity Probe B experiment for nearly fifty years. He tells us about the spacecraft's proofs of Einstein's General Theory of Relativity. A personal triumph for Emily Lakdawalla. Bill Nye explore space from underwater, and vice versa. Bruce Betts tells Mat Kaplan how he met the answer to the space trivia contest. (There will be a new contest next week.)
