If you are here asking: "Is this a science meme?"

Probably, yes. We use the Dawkins definition of meme: a replicating idea, not just an image macro with a fact on it. A good post here doesn't need to teach you something. It needs to make you ask something: who, what, where, when, and especially why or how.

Science isn't a filing cabinet of facts, it's a conversation. For example, a photo of an eel or other localized wildlife counts because most people never see one, and wonder is the first step of inquiry. A car meme counts if it makes you curious about what's under the bonnet. If you want to talk about something you noticed in the world, chances are someone else wants to talk about it too.

We encourage sillyness, especially where a post creates interesting discussion. Experimenting is encouraged, but keep it in good faith and never punch down.

Not a lot of atmosphere on the moon.

Transmitting heat across distances in effectively a vacuum doesn't work too well.

Just look a the size of the radiators the ISS has to have, and they're not even sending heat anywhere in particular, that's just getting it off station

You're getting thermal radiation and convection confused. The ISS has giant radiators because it's a right pain in the ass to turn heat into thermal radiation, and it cannot rely on convection to cool things like you can here on earth. Turning thermal radiation into heat on the other hand is pretty trivial. Just don't reflect it and it'll turn into heat. These things aren't transporting heat across distances. They are transporting thermal radiation across distances. That works as well in a vacuum -- if not better -- as it does on earth.

If thermal radiation doesn't work in a vacuum, how is the sun heating anything up?

I stand corrected

The mirrors on Earth don't transfer the energy using the air between the mirror and the collector, they just bounce the spicy photons which can travel even better in a vacuum.

Or in the Atacama, the Desertiest desert on earth!

Where the gigantic Cerro Dominador Termosolar Power Plant opened a couple years ago.
