More fun from last week's show in front of a big Pasadena audience. Mike 'Pluto Killer' Brown tells Bill Nye and Mat Kaplan about why he is looking forward to our first close-up view of that former planet. Barbershop quartet Hi-Fidelity also returns with another Star Trek parody. Bill Nye looks forward to a new asteroid mission. Bruce Betts takes a minute to welcome home the Shuttle LIFE experiment that rode on Endeavour. All this, and a What's Up? new space trivia contest.
