Discovery didn't get off the pad, but we still had a great time at the Kennedy Space Center last week. Join us on this visit. Emily Lakdawalla and Bill Nye report on the fantastic success of EPOXI/Deep Impact during its November 4 flyby of Comet Hartley 2. Bruce Betts has the lowdown on the up high. He and Mat also have another copy of Mary Roach's Packing for Mars" to give away in the new space trivia contest."
