I find it very thought-provoking that on the moon (well, in the lunar lander, anyway) moon rocks smelled like burnt gunpowder, but after having been on Earth a while, they don't.

I hadn't known that. But I do know that anything that's been in vacuum for awhile will have a characteristic smell, it's probably the same thing. It's weird that the cleanest environment on earth gives things a smell. I have no idea why that is -- maybe the things become depleted of oxygen or nitrogen (or lose their protective layers of water and hydrocarbon) and once they get into the air some reaction happens.

A long time ago, when I was a young teenager and before I became a Christian, I used to worship the moon. And it made me very angry that people had put a flag on her.
