Visiting the Spacecraft Technology Expo

Spaceplanes, spacesuits and rockets, oh my! Mat Kaplan talks to exhibitors and others at the first ever Spacecraft Technology Expo in Los Angeles. And the Scarecrow has no brain! That’s according to Emily Lakdawalla, who saw the stripped down Mars rover in action. Bill Nye says we should have commercial space AND planetary science. Bruce Betts joins Mat to explain the imminent annular solar eclipse and give away a Planetary Radio t-shirt in the new space trivia contest.
