Join Mat Kaplan in California’s Mojave Desert for special coverage of not one but two rocket flights and a real world test of PlanetVac, the innovative, radically simple way to collect surface samples from other worlds. PlanetVac replaced one foot of a Masten Space Systems Xodiac rocket for back-to-back hops across a test site. We also talk with Masten CEO Sean Mahoney. Planetary Society Chief Scientist Bruce Betts also made the trip. He’ll also open a super massive contest for PlanRad listeners in our What’s Up segment.

Question from the week before:

What hardware did The Planetary Society provide to the Phoenix Mars lander mission?


A silica glass mini-DVD provided by The Planetary Society was mounted on the Mars Phoenix lander. It was loaded with 250,000 names and a library of Mars-related fiction, art and radio, including works by Ray Bradbury and Arthur C. Clarke.
