Space is hard. Sample collection and return is harder still. That’s why the radically-simplified PlanetVac system from Honeybee Robotics is so intriguing. Join Planetary Society Chief Scientist Bruce Betts and host Mat Kaplan on a tour of Honeybee that includes a PlanetVac demo. Bruce returns for this week’s What’s Up jaunt around the night sky. Planetary Society Digital Editor Jason Davis shares big news about the LightSail 2 solar sail and the next SpaceX Falcon Heavy launch.
