NASA finds comfortably warm spots all over the Moon
Shaded bits of lava tubes stay at 17°C all lunar day and all lunar night, a contrast with the rest of Luna’s frequent fluctuations
Data from the Lunar Reconnaissance Orbiter (LRO) has led scientists to conclude that the Moon hosts around 200 “pits” that offer stable and human-friendly temperatures.
The pits “always hover around a comfortable 63F/17C, NASA stated on Wednesday.
A steady 17C contrasts markedly with the rest of the Moon’s surface, which fluctuates between 127C/260F to -173C/-280F across a full Lunar day.
Coping with those temperatures vastly complicates lunar exploration, for machines and humans.
Warm spots on the Moon are therefore hot property.
“Since the discovery of pits on the Moon by JAXA’s SELENE spacecraft in 2009, there has been interest in whether they provide access to caves that could be explored by rovers and astronauts,” wrote researchers who published information on the pits in the journal Geophysical Research Letters.
The paper’s three authors, UCLA professor of planetary science David Paige, Paul Hayne of the University of Colorado Boulder, and UCLA researcher Tyler Horvath, used data from The Diviner instrument onboard the LRO, which had monitored temps on the lunar surface for more than 11 years.
The researchers focused on a mostly cylindrical pit inside Mare Tranquillitatis, the same region visited by Neil Armstrong and Buzz Aldrin in 1969, as its thermal environment was more hospitable than any other place on the lunar surface.
The group ran time-dependent 2-D and 3-D models using the data to understand the geometry and heat transfer that could lead to the elevated temperatures.
The researchers concluded that the temperature inside the pit was not only a comfortable temperature, it was very possibly attached to a cave that would also have a similar stable environment.
“If a cave extends from a pit such as this, it too would maintain this comfortable temperature throughout its length, varying by less than 1°C over an entire lunar day,” wrote the researchers, who hypothesized the pit and others like it were created by the ceiling of a collapsed cave.
“For long term colonization and exploration of the Moon, pits may provide a desirable habitat: they are largely free from the constant threats of harmful radiation, impacts, and extreme temperatures,” wrote the researchers. “Thus, pits and caves may offer greater mission safety than other potential base station locales, providing a valuable stepping stone for sustaining human life beyond Earth.”
Better still, the boffins have spotted many pits on the Moon’s nearside, a location that offers the chance for direct-to-Earth communications.
NASA is returning to the Moon with commercial and international partners to both further scientific knowledge and expand human presence in space.
The space org’s Artemis program aims to take humans to the lunar south pole by 2025 in the first crewed lunar landing since 1972’s Apollo 17.

What a fantastic discovery. Why hasn’t somebody thought of creating caves on earth so thar we can live in them to avoid climate change?

Hi Alan and PSI Readers,
What a fantastic discovery!!! The moon’s surface is not homogenous (uniform). As children we have imagined to see the man-in-the-moon. It seems NASA scientists will try anything to keep a job.
Have a good day, Jerry

Is it me or did anyone else know that living underground has a pretty much constant temp. And what a great way to live, maybe we could dig a hole for these smart people at NASA and have them live there for the next decade or so and see what other wonderful things they can find for us. I mean seriously do we actually pay people to study this crap.

My God, anthropogenic global warming has been discovered on the moon! No doubt being caused by Nazi scientists, who secretly emigrated there and established colonies just before the fall of the Third Reich.
I love this site, it keeps writing articles that are totally oblivious to the fact that we live in a society where absolutely everything, including science, has been politicized to death by the woke left. Ignorance is bliss, I guess.
