China News Service, Beijing, February 20 (Guo Chaokai) According to the China National Space Administration's Lunar Exploration and Space Engineering Center, the Chang'e 4 lander and the "Yutu 2" lunar rover on the back of the moon were at 13:30 on February 19, respectively. Finished the 27th day of the month at 1:48 and entered the moonlight dormancy.
Up to now, Chang'e-4 has worked on the lunar surface for 778 Earth days, the lunar rover has a cumulative mileage of 652.62 meters, is in good condition, has energy balance, and all scientific loads are working normally.
Scientists continue to produce scientific research results based on first-hand detection data, revealing in-depth various scientific problems on the back of the moon.
In addition to the good news from Chang'e-4 from the back of the moon, there are also new developments in the exploration of Mars on the other side.
According to NASA news, at about 4:55 on February 19th, Beijing time, the "Perseverance" rover successfully landed on Mars to find traces of life that existed on ancient Mars.
The landing method of "Perseverance" adopts the same "sky crane" method as that of the "Curiosity" rover, so as to meet the requirement of smoothly dropping the rover weighing about one ton on the surface of Mars.
Earlier, the UAE's "Hope" probe and China's Tianwen-1 probe had already reached Mars.
China's first Mars exploration mission, Tianwen-1, successfully orbited Mars on February 10, 2021, completed an orbital plane adjustment, and is currently operating in a ring-fire elliptical orbit.
As of 9 o'clock on February 19, Tianwen No.1 is 205 million kilometers away from the earth.
The detector is in a stable state, all systems are working normally, and the ground station tracking is normal.
After about three months of ring fire detection, Tianwen-1 will choose an opportunity to land on a predetermined area on the surface of Mars.
