The InSight lander has only just arrived on Mars. Now, OSIRIS REx has reached asteroid Bennu after traveling through deep space for a year and a half. We’ll talk with the Planetary Society’s Jason Davis about this mission that will bring a sample of Bennu back to Earth after it has learned all it can over the next 19 months. We’ll also hear from the young student who gave the asteroid its name. Then we’ll return to the Red Planet for a conversation with the leader of the InSight mission, Bruce Banerdt. We’ve got very special prizes for this week’s What’s Up space trivia contest.
