A Near Miss for Mars and Bill Nye Pays Tribute to Mercury!
A fifty meter asteroid will narrowly miss Mars according to Don Yeomans, Manager of the NASA Near Earth Object Program Office. We talk with Don at the Jet Propulsion Laboratory about the more than 5,000 rocks and comets already found that could one-day target Earth. Emily Lakdawalla explains why our eyes on Mars probably won't be watching that asteroid pass by, while Bill Nye the Science Guy celebrates humankind's return to the planet Mercury. Bruce Betts gives us the gift of the night sky during What's Up, and Mat Kaplan has a present for Bruce. Both of them present new space trivia contest awarding a Year In Space calendar.
