A Chinese vehicle began exploring the hidden face of the Moon



The vehicle, which was baptized Yutu 2 (in Chinese mythology, "Yutu" means "jade rabbit", Chang's mascot, a goddess living on the moon) left a ramp on the surface Thursday at 10:22 during nighttime, about 12 hours after Ship Chang 4 landed.

It is "A small step for the vehicle, but a huge leap for the Chinese nation", said Wu Weiren, the main designer of the monthly project.

In a statement, the Chinese National Space Administration (ANEC) wanted this "Yutu 2 can carry out explorations without fear and can have a more stable, wider and longer journey."

The off-road vehicle has a panoramic camera, an infrared spectrometer and a radar, tools with which it will try to get images of the monthly surface and to detect its structure and composition.

Chinese scientists are optimistic and expect "great breakthroughs" the state agency insured Xinhua.

"The hidden face of the Moon has very special features and has never been explored in situ, so Chang 4 could bring us great insights, explained the director of the Chinese Academy of Sciences (CAS) sundae exploration department, Zou Yongliao.

"We can detect deep hidden information in the Moon, I think there will be surprising scientific findings", he added.

The expert explained that there are large differences between the two sides of the moon: for example, 60% of the visible face is covered by basalt seas, while most of it is hidden in the mountainous areas of the anorthosite – 19 of the 22 lunar seas are in the visible area of ​​the Earth.

Also, scientists will try to clarify other issues such as why the monthly cortex is much thicker on the hidden side.

"The stones of the hidden face are older, analyzing their composition could help us better understand the evolution of the moon", Zou pointed out.

This pioneering mission could help to understand the Earth's and the Lun's common past, as pointed out by the Department of Geology and Geophysics researcher, Lin Yangting, who states that the Moon could offer "knowledge of the primordial history of the Earth".

Other goals are trying to find out the reasons why there was a huge bombardment of asteroids about 3.9 billion years ago or to analyze cosmic radiation and the interaction between the solar wind and the lunar surface.

These latter two factors are the key to a possible human crew mission to the terrestrial satellite because it could be harmful to humans.

The probe not only has Chinese instruments but also from countries like Sweden, Germany and the Netherlands, with which scientists want to detect weak signals emitted by celestial distant bodies in outer space, because the Moon mass would absorb the interference of the waves emitted by Earth.

If this goal had been met, experts could have new data on the origin and evolution of stars and galaxies.
