Supermoon Lunar Eclipse

Last night we experienced a total lunar eclipse here in Chicago. Unfortunately, significant cloud cover meant that much of the event went unseen. That was unfortunate, because eclipses are fantastic. To explain it we have this piece from the BBC.

And for those were either unable to see it or did not know about it, here is one of the photos I took.

Moon Bases

Today’s post falls somewhere between just for fun and science reality. Remember moon bases? Newt Gingrich’s ridiculed comment about a habitable moon base by 2020? Well, one problem with colonies on other planets—or even interstellar transport for that matter—is radiation. The moon has no magnetosphere and no atmosphere. So it can be bombarded by both radiation and meteorites.

But, now we have lava tubes. Well, in theory at least. Scientists have run the numbers and found that if lava tubes exist on Mars, they would be structurally sound to support colonies within lava tubes. And that brings us to the raison d’etre of today’s post: the diagram used to explain that science.

I present you all with your hypothetical moon base: New Philadelphia.
