Faith Vilas of the Planetary Science Institute leads the effort to put a telescope on XCOR's sub-orbital spaceplane called Lynx. She tells us the hows and whys on this week's show. Emily Lakdawalla goes from the beautiful to the sub-rhyme as she shows us clouds rolling over Mars and introduces Periodic Table rapper Oort Kuiper. Bill Nye speaks of the significance of antimatter found orbiting our planet, and salutes NASA's creation of a new directorate. Bruce Betts and Mat Kaplan don't rap about the night sky (thankfully) but they do become rapturous over a new space trivia contest.
