Summary

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.

0:00.0	Lonely Uranus and Neptune and a very busy April this week on Planetary Radio.
0:07.0	Welcome, I'm At Kaplan of the the Planetary Society, with more of the human adventure across our
0:15.8	solar system and beyond.
0:18.1	Call the mice giants, call them outer planets, call them the Blues Brothers, or
0:22.2	sisters if you prefer.
0:24.0	Those big cold worlds beyond Saturn are still shrouded in clouds of mystery that can only be solved by a visit.
0:32.0	Our guest, Planetary Scientist scientist Amy Simon will provide a tour.
0:36.4	As always, we'll visit with Bruce Betts and play Where in the Solar System once again.
0:42.3	Planetary Society Digital Editor Jason Davis will get us rolling around the neighborhood,

1:03.6	Yeah, it really gives you a sense of how powerful this explosion that they're about to ignite in deep space is.
1:11.2	Hayabusa is about to deploy its SCI experiment that stands for a small carry-on impactor and

1:21.0	Yeah, they would fit on your desk, this isn't a very big experiment, but packs a lot of power in this little box of plastic explosives and it's going to shoot a copper plate into Ryugu and create an artificial crater on the surface.
1:34.3	And if all goes well, while this is going on, Hayabusa 2 is going to be hiding behind Ryugu because
1:40.0	it doesn't want to be anywhere near this explosion when it happens.
1:43.6	Are you enough of a trekky to know about the roughly 1,000 times over the course of Star Trek
1:49.9	that a ship, the Enterprise or somebody else has hidden on the other side of a planet or
