When will we return to Uranus and Neptune? Planetary scientist Amy Simon explains why a mission to the so-called ice giants is a high priority as she tells us about these mysterious, blue worlds. Planetary Society Digital Editor Jason Davis takes us through what promises to be a very busy month in space, with the launch of the second Falcon Heavy, a moon landing by Israel’s Beresheet probe, and how Hayabusa2 will blow a hole in asteroid Ryugu, complete with sound effects. Then join us for another round of What’s Up in the Solar System.
