Right, I'm roughly aware that's a concern on Earth too which is why I was wondering. How's the thermal conductivity of the moon?

- szvsw 2y agoLooked up some papers, and seemingly super low compared to what I would have initially guessed - probably because it’s porous/fluffy/sharp dust with lots of small voids/less compacted I’m guessing. Like, orders of magnitude less than the ground on earth. Not my area of expertise though and was just cursorily skimming papers for values. Specific heat cap and density seem like what you would expect for any rocky materials.
- justinclift 2y agoMight need to pour a bunch of water on the soil to increase the thermanl conductivity and make sure to never heat it above freezing?
- foxyv 2y agoWater would boil on the moon, any ice would sublimate. You would be better off just compacting the regolith.
- qskousen 2y agoGeothermal heat transfer is greatly affected by the moisture of the soil, which on the moon would be pretty low as you can imagine.
- lstodd 2y agoNo one ever drilled the Moon to any useful extent. All we know is that it's mostly dusty on top.
