NASA's Lunar Reconnaissance Orbiter Zone has been orbiting the Moon since 2009. Thanks to the latest measurements conducted by LRO, integrated with some mathematical models, NASA has discovered that there are shaded areas in the fall known as Crater Marius, where the average temperature remains at 17 C°. This is a significant deviation from the surface temperature, which is 127 C° by day and 173 C° by night.
These caves on the moon were first discovered in 2009, and they are now considered to have collapsed lava tubes -- these are real tunnels, up to hundreds of metres, which were formed when the moon was still volcanicly active -- and as the lava flowed, the surface material became solid, creating lava tunnels underground, and some of these tunnels collapsed over millions of years of moon history, creating caves that we now see from the orbit of the moon.
So far, this is one of the most reliable theories of origin in these caves. " said Tyler Horvath, a graduate of planetary sciences at the University of California, who led a new study recently published in Geophic Research Letters.
The importance of finding caves and tunnels "room temperature"
Since their first discovery, the lava caves have assumed the presence of tunnels and caves in their vicinity, and it soon became clear that these are some of the most likely locations for the long-term stay of a person on our satellite.
Staying under the rocky layer of the Moon provides protection against solar radiation and temperature changes, and there is evidence that at least two of the pits found to date lead to a larger complex of caves and tunnels.
"," says Noah Petro, a researcher of the LRO project at the Goddard Space Mission Center of NASA. "The knowledge that they create a stable heat environment helps us to understand these unique lunar features and the prospects for studying them one day."
The studies that led to the determination of comfort temperatures were based on data from the Diviner thermal chamber installed on the LRO probe. The researched quarry has a diameter of about 100 metres and is located in an area called the Sea of Calm. Photos also show the presence of at least one cave coming out of the studied pit. Almost certainly the average temperature will be the same.
The launch of the South Korean probe to the KPLO Moon is scheduled to take place on 4 August. This satellite, which will in fact be a technology demonstration, has a NASA optical camera based on the LRO camera, aimed at observing poles, analysing ice deposits in the South Pole, which is the main mission of the first Artemis mission.
However, by the end of 2022, a number of CLPS ground vehicles will be launched, the purpose of which is precisely to continue and expand all research initiated by probes in orbit into areas and possibilities for the next astronauts of the Artemis missions.
