Mat visits NASA's program that put middle and high school science teachers together with planetary scientists in California's desert to research how we'll detect life elsewhere in the solar system. Emily Lakdawalla's Q&A looks for planet Vulcan or just scattered Vulcanoids, while Bruce Betts catches some Zs -- in the names of astronauts -- as part of the What's Up space trivia contest.
