China-Singapore, Beijing, July 16 (Reporter Sun Zifa) Springer Nature’s professional academic journal “Nature Astronomy” recently published a planetary science paper saying that researchers have discovered a potentially accessible underground tunnel originating from an open pit on the moon. Evidence of tunnel. The results of this study have enhanced people’s understanding of lunar geology and may become an ideal location for a lunar base, thus potentially serving as a refuge in future manned missions on the lunar surface.
The paper said that more than 200 craters known as skylights have been discovered on the lunar surface, some of which were formed after the collapse of underground lava tubes. Accessible lava tubes or channels may provide a warmer environment than the lunar surface, but it has previously been uncertain whether they can lead to large underground caves.
In this study, co-authors of the paper, LC and LB of the University of Trento in Italy, and collaborators, analyzed radar data from the Lunar Reconnaissance Orbiter and found that radar brightness on the west side of the crater increased. Jinghai Crater is the deepest known crater on the moon, with a radius of approximately 100 meters, with vertical or overhanging walls and a sloping bottom.
The authors of the paper used radar images to conduct simulations and found that these observations could be explained by the presence of a cave void or pipe spreading from the west side of the bottom of the pit. They estimate that the pipeline is located at a depth of 130-170 meters, 30-80 meters long and about 45 meters wide. The cave may be flat or inclined at an angle of up to 45 degrees and may be accessible.
The authors concluded that the pipes or channels discovered in this study may be a common feature under the lunar plains, and that the Jinghai Pit and its channels may be an ideal site for a potential lunar base. The method used in the study may also be suitable for evaluating and characterizing other lunar craters to discover more channels.
