BEIJING, January 31 (Xinhua). Module intelligence and descent probe Chang & # 39; e-4 was awakened by sunlight after a long "sleep" in the first extremely cold moonlit night. This is reported on Thursday by the National Space Administration of China (CNSA, initials in English).
The landing module woke up on Wednesday at 8:39 pm, and the reconnaissance module Yutu-2 (Jade Rabbit-2) – on Tuesday around eight o'clock in the evening, after spending its first moon night. After the first soft landing of the story on the hidden side of the moon, the administration exposed.
The Chinese probe was launched on December 8, 2018 and landed on January 3 in the crater of von Karman at Aitken’s lunar-south pole.
The lunar day is 14 on Earth, and the night on the satellite has the same duration. Probe Chang & # 39; e-4 switched to inactive mode on a moonlit night due to lack of solar energy.
Thus, both the module and the scanner module exited automatically in this way, depending on the elevation angle of the sunlight. Key probe tools started to work.
Currently, the rover is located about 18 meters north-west of the landing gear. The administration reported that communications and data transmission between the ground control console and the probe via the Queqiao transmitting satellite (the Magpie bridge) is stable.
As a result of the effect of synchronous rotation, the cycle of the Moon's motion coincides with the cycle of rotation, therefore the visible side of the Earth is always the same.
“The hidden face of the moon has unique characteristics and has never been explored“ on the spot, ”so Chang e e-4 can bring us new breakthroughs,” said Zou Yunlyao, director of the lunar and deep-space research department. Chinese Academy of Sciences.
On the first lunar day, the landing gear and the scanner took photos of each other, and the camera mounted on the top of the landing gear took panoramic pictures from a 360-degree view of the vicinity of the probe.
“In the panoramas, we see that the probe is surrounded by a multitude of small craters — this is really exciting,” said Li Chunlai, deputy director of the National Astronomical Observatory of China and commander-in-chief of the ground application system Chang e-4.
According to scientists, the UTU-2 exploration module will encounter significant problems during operation due to difficult terrain.
The scientific tasks of the Chang & # 39; e-4 mission include astronomical observation of low-frequency radio, soil research and geomorphology, detection of the composition of minerals and the surface structure of the moon at a shallow depth, and measurement of neutron radiation and neutral atoms.
The Chang & # 39; e-4 mission embodies China’s hope of combining human wisdom in space exploration with equipment developed by the Netherlands, Germany, Sweden and Saudi Arabia.
