Water on the Moon? Eh, Not So Much

Another astro-map from Universe Today. This one's of the moon:

It's a topographical map, recently put together with data from Japan's Kaguya satellite. It shows the crests and dales of the moon's surface, from the Dirichlet-Jackson Basin near the equator (11 km high) to the Antoniadi crater near the south pole (9 km deep). (Is it official policy, by the way, that place names on the moon be unpronounceable?)

But besides mapping the moon's topography, the Japanese researchers did a neat trick. They measured the roughness of the moon's surface, which allowed them to figure out if there's water underground. See, if there is water there, then it would act as a sort of lubricant, and the surface would exhibit more flexibility. But if there's no water, then the surface will be more rigid, just like the rough, rigid surface of a desiccated fruit. And the moon? Turns out it's pretty rigid. So: no water. Bummer.

What's that, David Byrne? You have something to say on the topic of water underground? A-and the moon, too?

Thank you, David. Thank you for that.

I don't know if i buy their methods. How do we know this is up to snuff? I say we get i guy up there and have him traipse around with a divining rod. Then we'll know for sure.

Not a bad idea. And I hear there's water on the moon, so he could use that for his life support systems. said...

Hello, it's Dirichlet-Jackson basin, actually:

innovation is very natural and happens in the "real world" as new plants and animals colonize new ecological niches.

I would be aware that as somebody who really doesn’t comment to blogs a lot (in actual fact, this may be my first put up), I don’t think the time period “lurker” is very flattering to a non-posting reader.
