The landing and driver of the Chang’e 4 probe have been put to sleep for the night of the month after they have been working stably on the 23rd of the month, the China National Space Administration’s Moon Search and Space Program Center said.
Both the lander and Rover were put to sleep on Friday – Rover at noon and lander at 9.40pm, according to downtown.
The day of the moon is equal to 14 days on earth, and the night of the moon is as long. The Chang’e 4 probe, which has been put to sleep on the night of the moon due to lack of solar power, had been 661 Earth days behind the moon since Sunday, and the driver has traveled 565.9 meters.
During the 23rd day of the month, Yutu 2 went northwest, traveling toward an area with basalt and an impact crater area with high reflectivity. On the way to the destination, an infrared spectrometer near Rover was used to detect a rock about 30 centimeters in diameter. The research team analyzes the submitted data.
The researchers performed the first systematically documented radiation measurements with the data collected by the Neutron Radiation Detector on the moon. According to a study published in Science Advances, the surface of the moon is highly radioactive – about two or three times the level of the International Space Station, 5-10 times by civilian flight and 300 times the surface of the Earth in Beijing.
The study provided a reference for assessing the radiation hazards of the lunar surface in order to plan the radiation protection of future lunar astronauts.
The Chang’e 4 probe, launched on December 8, 2018, made its first soft landing at Von Karman Crater in the Aitken Basin of the South Pole in the second half of the month on January 3, 2019.
The Yutu 2 has significantly exceeded its three-month planned life cycle and has become the month’s longest driver.
China’s first lunar sensor, Chang’e 1, was launched on October 24, 2007, making China the fifth country to independently develop and launch the lunar probe and usher in a new era for deep space exploration.
Chang’e 1 mapped 3D images of the lunar surface, analyzed the distribution of elements, measured the depth of the lunar soil, and studied the environment between the earth and the moon. Thanks to this task, Chinese scientists published the first complete map of the lunar surface in November 2008.
As it orbited the moon for about 16 months, the probe made a controlled fall on the surface of the moon in March 2009.
Seven years after the launch of Chang’e 1, China launched an experimental spacecraft to test technologies used on the Chang’e 5 voyage, which are expected to bring lunar samples back to Earth.
Experimental spacecraft, containing the return capsule and the service module, flew around the half moon orbit, and paluukapseli contact Siziwang Banner, Inner Mongolia Autonomous region, November 1, 2014.
