Last year, in January, the CNSA (China National Space Administration) launched a lunar mission. Later the lander successfully touched the far side of the Moon. Well, Chang’e-4 rover of China is the first-ever mission to touch the far side of the Moon. Since landing, it is exploring the surface to unveil lunar mysteries. Today, the team behind Chang’e-4 is releasing new insights regarding what they have had discovered under the lunar surface. In a new paper, the researchers have published the primary ground-penetrating radar analysis of the lunar surface. As per the study, the lander has found coarse and porous material dotted with rocks beneath the surface. The probe has discovered a different kind of rock than the ones present on the near side of Moon. Maybe the difference in material is due to material brought up by a colossal collision.
The probe has assessed the South Pole-Aitken basin, which is the largest and ancient crater on the other face of the Moon. As per the study, the crater has a diameter of over 1500 miles has plenty of loose deposits of pulverized dust and rock. The researchers say 39 feet crater is the same as that which Apollo astronauts have had found on the near side of the Moon. The Lunar Penetrating Radar aboard has enabled the rover to study the Moon using radio waves. Those signals can travel as far as 131 feet under Moon’s surface. Notably, the range is thrice more than the former lunar mission of China, Chang’e-3.
Li Chunlai, leading author of the study, said below the surface of the CE-4 landing site is much transparent to radio signals. He added this qualitative assessment pinpoints an entirely different geographical context for both landing sites. Even more, the presence of granular and porous material may be a result of meteor collisions over the surface. The data collected during an initial couple of days has assisted in developing the first electro-magnetic image of the underground. The outcomes of the study are available in the journal Science Advances (26th Feb. edition).
