Both the lander and the rover of the Chang & # 39; e-4 probe went into sleep mode for the lunar night on Friday (Beijing time), according to the Center for Lunar Exploration and Space Program of the China National Space Administration.
Chang & # 39; e-4 probe, released on December 8, 2018, made the first – any soft landing of the Von Karman crater in the South Pole-Aitken basin across the moon on January 3.
A lunar day equals 14 days on Earth, a lunar night of the same length. Chang-e-4 probe goes into sleep mode on moonlight due to lack of solar power.
During the ninth lunar day of the Moon's probe, the lander and climber scientific tools were working well, and a new batch of 2.9 GB scientific discovery data was sent to the main research team for analysis.
As a result of the effect of blocking the tides, the cycle of the moon's rotation is the same as its cycle of rotation and the same side is always facing the Earth.
The far side of the moon has unique characteristics, and scientists expect Chang's e-4 to deliver breakthrough results.
The scientific tasks of Chang-e-4's mission include low-frequency radio astronomical observations, studies. terrain and terrestrial forms, detecting the mineral composition and shallow lunar surface structure and measuring the neutron radiation and neutral atoms.
Chang & # 39; e-4 mission embodies China's hope of combining wisdom in space exploration with four payloads developed by Netherlan DS, Germany, Sweden and Saudi Arabia.
