Lava Tubes on the Moon Maintain Comfortable Room Temperatures Inside

Searching for a comfortable place to set up a research station on the Moon? Look no further than the interior parts of lunar pits and caves. While lack of air will be an issue, new research indicates these underground sanctuaries have steady temperatures that hover around 17 Celsius, or 63 Fahrenheit, even though the Moon’s surface heats up to about 127 C (260 F) during the day and cool to minus 173 C (minus 280 F) at night.

Lunar pits, or lava tubes were discovered in 2009 by the Lunar Reconnaissance Obiter and Japan’s Kaguya spacecraft. These are deep holes on the moon that could open into vast underground tunnels. They likely could serve as a safe shielding from cosmic rays, solar radiation and micrometeorites for future human lunar explorers. But now we know they could provide thermally stable sites for lunar exploration.

These long, winding lava tubes are like structures we have on Earth. They are created when the top of a stream of molten rock solidifies and the lava inside drains away, leaving a hollow tube of rock. For years before their existence was confirmed, scientists thought there were hints that the Moon had lava tubes based on observations of long, winding depressions carved into the lunar surface by the flow of lava, called sinuous rilles.

So far, about 200 lunar pits have been found and at least 16 of these are probably collapsed lava tubes, with the potential for ‘livable’ space, said Tyler Horvath, a UCLA doctoral student in planetary science, who led the new research. Two of the most prominent pits have visible overhangs that clearly lead to some sort of cave or void, and there is strong evidence that another’s overhang may also lead to a large cave.

1. I tried to get one...

...but it looks like Zillow has already snapped up a lot of the lunar lava tubes in the best locations.

2. LOL!!! Maybe you can visit when they go Air BNB...

3. Well, if they maintain a comfortable room temperature...

...then they are doing a lot better than a lot of hotel rooms I've had.

4. I would prefer to keep this planet habitable

instead of having to live in a moon lava tube.

5. Exactly.

6. I have been on a rereading kick lately,

and I reread Robert Heinlein's The Past Through Tomorrow, a series of short stories from the 1930s through the 1950s that covers an alternate history.

In the stories that take place on the moon, Heinlein has the main habitation in lava tubes and lava bubbles, with additional living space dug below and to the sides of those tubes.

It's amazing what possibilities that he saw in the future!

7. The temperature sounds ideal but the pesky oxygen situation might a deal breaker.
