Chief Scientist / LightSail Program Manager for The Planetary Society
Senior Communications Adviser and former Host of Planetary Radio for The Planetary Society
Japan’s Hayabusa2 is just 6 kilometers from asteroid Ryugu as it prepares to snatch samples of the space rock for return to Earth. ISAS/JAXA Director General and former Hayabusa Mission Project Manager Hitoshi Kuninaka joins us for a conversation about the spacecraft and what’s ahead. Then we hear from Hansjörg Dittus of the German Aerospace Center (DLR) about the German/French lander called MASCOT that was carried to Ryugu by Hayabusa2. Emily Lakdawalla is the new editor of the Planetary Society’s distinguished magazine, The Planetary Report. Bruce Betts explains how to get the most out of a lunar eclipse and the closest Mars has come to Earth for many years. We also give you an extra week to enter the space trivia contest!
