Based now at the SETI Institute’s Carl Sagan Center, Franck Marchis recently visited the Planetary Society for a conversation with host Mat Kaplan. He uses several of Earth’s most powerful telescopes to study what he calls multiple asteroid systems. Emily Lakdawalla dons her 3D glasses for a spectacular view of a lunar crater. Bill Nye can’t seem to stay away from Washington DC! And that’s where Bruce Betts and Mat went for a very special What’s Up segment in the Smithsonian Institution’s National Air and Space Museum. They play a live version of the space trivia game, and they give listeners yet another chance to win.
