At the beginning of human history, caves provided people with protection from the elements and a place they call home. Now, similar formations on the Moon could provide astronauts with a safe haven on the Moon, thanks to Earth-like temperatures.

Researchers at the University of California, Los Angeles, found that the moon has craters with shaded regions that hover steadily around 63 degrees Fahrenheit (17 degrees Celsius), a stable temperate range for humans. the magazine Geophysical Research Letters The study was published in July.

These craters, which may lead to caves that could also provide human shelter, have temperatures that could make moon exploration and long-term human habitation safer, as scientists will be able to set up thermally stable base camps.

David Page, co-author of the study, a professor of planetary sciences at the University of California,… new version. Paige also leads the Diviner Lunar Radiometer Experiment, an instrument on NASA’s Lunar Reconnaissance Orbiter.

Now that there is a better understanding of potential craters and caves, scientists can accelerate the pace of envisioning a viable permanent station, shielded from the harsh conditions of the lunar surface.

“We can establish a long-term presence on the Moon sooner than possible,” said study lead author Tyler Horvath, a doctoral student in planetary sciences at the University of California, Los Angeles.

Unlike the surface of the Moon, which warms up to 260 degrees Fahrenheit (127 degrees Celsius) during the day and drops to minus 280 degrees Fahrenheit (minus 173 degrees Celsius) at night, these lunar craters in the Mare Tranquilites region are friendly to humans, and are temperature stable. .

(Mare Tranquillitatis, better known as calm seawhere Apollo 11, the first mission to put humans on the moon, landed, due to its relatively smooth and flat terrain.)

The data comes from analysis of images taken by NASA’s Lunar Reconnaissance Orbiter spacecraft and computer modeling.

“These[craters]are well within the resolution of the cameras they’re trying to use,” said Briony Horgan, associate professor of Earth, Atmospheric and Planetary Sciences at Purdue University in West Lafayette, Indiana. “The fact that they were able to pull that data and show that it was very compelling, I think is a huge step forward in looking at the moon.”

Learning about these potential craters and caves helps scientists better understand how other extreme environments behave, such as the lunar polar regions where the Artemis mission is going, said Noah Petro, head of NASA’s Geology, Geophysics and Geochemistry Laboratory. The NASA Artemis program It aims to return humans to the moon and land the first woman and first people of color on the moon by 2025.

“Artemis’ goal is to send humans to the area around Antarctica, where we know there are some very cold places,” Pietro said by email. “Fortunately, we have a large amount of data for the Antarctic region that Artemis will visit.”

Extreme lunar surface temperatures have made it difficult for NASA to create fully functional heating and cooling equipment that would produce enough power to allow long-term exploration or habitation of the Moon, according to the news release. However, NASA may not need as complex equipment as it is currently assumed to make exploration and habitation a reality, this research has shown.

With the help of the Lunar Orbiter, scientists discovered craters on the Moon in 2009, a discovery that has led scientists to wonder if there are connected caves that could be explored or even used as shelters.

“It’s likely that about 16 of the more than 200 craters are collapsing lava tubes,” Horvath said in the press release.

When the lava tube – a long, hollow tunnel and lava-like structure – collapses, a crater opens that can create an entrance to the rest of the cave.

There were at least two, probably three craters, with overhanging protrusions leading into the caves, the statement said.

Horgan said the caves would be a stable environment for lunar habitats because they provide some protection from solar radiation and the impacts of small meteorites. These formations could also provide a measure of cosmic ray protection, according to NASA.

Horgan added that it would be useful to build on existing research with radar data to find additional potential caves.

The research, she said, “gives engineers who are really thinking about how to design a habitat on the moon real numbers to work with.” “This will be very important going forward.”

Currently, NASA has plans for robotic exploration of the Moon through the Moon Lunar Commercial Payload Services Program. start in December 2022The cargo flights will connect instruments that navigate and map the lunar surface, conduct investigations, measure radiation levels and assess how human activity affects the moon. These flights give scientists the ability to reach anywhere on the moon, including Mare Tranquillitatis, Pietro said.

“Continuing to map the lunar surface temperature is a top priority for LRO, as we will be able to use this information to not only better understand the environment, and will test future missions to the surface,” Pietro said, “but we can also see how different species respond. From surface materials to the changing lighting conditions on the lunar surface.”
