14 DAY TRIAL // For a while now, photos of the Moon have been showing huge pits and channels across the lunar plains. The pictures taken in the 60's showed long and narrow channels across the Moon's surface, and scientists proposed the existence of lunar tunnels. Nowadays pictures support this theory as they give more details about these pits and researchers speculate that they are collapsed roofs of underground tubes.
As the Moon separated from the Earth it might have had the same lava flows inside it, as our planet. Scientists like Mark Robinson from the Arizona State University, claim that a real huge labyrinth might be hidden inside the Moon. Pitches “could be entrances to a geologic wonderland," he said. “We believe the giant holes are skylights that formed when the ceilings of underground lava tubes collapsed.”
Many unmanned probes have photographed enormous pits on the Moon's surface. The latest pictures come from the Japan's Kaguya spacecraft and show many holes on the same plain as the lunar valley. In the middle of the channel there is one in particular and scientists believe it to be caused by the collapse of an underground tube.
If there are indeed underground channels on the Moon, this might allow scientists to study it better. Staying in livable lunar layers would allow humans to be protected from radiation and also from the extreme temperatures on the Moon (100 degrees Celsius during the day and -150 degrees at night). Obviously, further exploration needs to be done before anyone can set camp inside the tubes.
“The tunnels offer a perfect radiation shield and a very benign thermal environment,” Robinson stated. “Once you get down to 2 meters under the surface of the moon, the temperature remains fairly constant, probably around -30 to -40 degrees C.”
For this idea to become applicable, scientists should first get on the Moon again. As they see more and more things on the lunar surface, a new human expedition is quite possible in the future.
