The Chinese probe Chang'e-4 landed on the Moon

Historic landing on the hidden face of the Moon -2 VIDEO

The Chinese probe Chang'e-4 has landed on the hidden face of the Moon this night, making the first "soft" on Moon landing on the unexplored side of our natural satellite, never seen from Earth. Composed of a lander and a rover, the probe is located in the preselected area at 177.6 degrees longitude east and 45.5 degrees south latitude at 10:26 am (Beijing time), as announced by the CNSA, China National Space Administration).

For communication assistance, Cnsa made use of the relay satellite Queqiao (Magpie Bridge), thanks to which the probe, on the Moon landed, has already been able to send the first photo, opening a new chapter in the lunar exploration. From here via Queqiao it will transmit signals and mission data to the Earth.

After the Beijing aerospace control center sent the signal at 10:15 am, the Chang'e-4 probe, launched on December 8, 2018, began to descend from 15 km above the Moon, and then on the Von Karman crater, in the basin of the South Pole-Aitken. The solar panels and the antennas on the probe were deployed under the control of the Beijing space engineers through the transmission of communications to the support satellite Queqiao placed about 65,000 km from the Moon, from where it will act as a "mirror" visible both from Earth and from the hidden side of the Moon.

The probe, which carried eight useful loads, two of which were developed through international cooperation, will conduct low-frequency radio-astronomical observations, inspect the soil and its conformation, detect the mineral composition, study the lunar surface structure and measure neutron radiation and the neutral atoms to study the environment, its nature and its evolution.

For Chinese astronomers, that side of the Moon is an ideal place because the Moon's mass protects it from the radio interferences of the Earth. From there it will be possible to study the origins and evolution of stars and galaxies, and to examine the dawn of the universe. They also believe that the Chang'e-4 low-frequency radio astronomical observation will fill gaps in astronomical observation.
