Join Mat Kaplan in California\u2019s 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.\xa0 PlanetVac replaced one foot of a Masten Space Systems Xodiac rocket for back-to-back hops across a test site.\xa0 We also talk with Masten CEO Sean Mahoney. Planetary Society Chief Scientist Bruce Betts also made the trip.\xa0 He\u2019ll also open a super massive contest for PlanRad listeners in our What\u2019s Up segment.\xa0 See images and video of the PlanetVac Xodiac flight test and learn more here:\xa0 http://www.planetary.org/multimedia/planetary-radio/show/2018/0606-planetvac-xodiac-test.html
