Emily Lakdawalla and Bill Nye the Science Guy join Mat Kaplan for a special remembrance of Neil Armstrong. Then we visit with the principal investigator for the first ray gun on Mars.

PlanRad Live welcomes space historian and writer Andrew Chaikin, former NASA Mars Czar Scott Hubbard, and Bill Nye the Science Guy to a live conversation at Planetfest: Curiosity Knows No Bounds, just a few hours before the triumphant landing of the big new rover on Mars.
