This week, we're back on the surface of the moon, where we'll meet our hosts, the JAXA astronauts. They're all excited to be on the moon again, and they're also psyched to be able to eat silkworms, which they've been experimenting with on the lunar surface. We're sure you've heard this one before, but it's worth repeating: silkworms are a totally different animal than the worms we used to eat on the ground. The JAXAs aren't the only ones who've tried experimenting with the moon: the atmosphere is also a problem, and the distant mountains are way too clear for our eyes to see. The only thing that's keeping us from eating silkworms is the fact that the moon is surrounded by mountains, which makes it hard to see where they are. We also learn that there are only two of them, and that they'll need to find a way to get to one of them.
