The 600 days a month of the Chang’e-4 probe brings huge scientific gains

The Yutu-2 rover of the lunar probe Chang’e-4 in China has set a record by traveling over 500 meters during its 600-day work on the other side of the moon, according to the China National Space Administration (CNSA ) on Wednesday.

The lander and the rover finished their work before the 21st Monday and switched to sleep mode on Tuesday. By this day, the rover had traveled 519.29 meters in a new record.

Queqiao (external bridge) is the relay satellite during normal working hours.

Scientists have conducted extensive research based on the data transmitted by the scientific charge on the rover and achieved positive results.

Using data from the visible / near-infrared image spectrometer, panoramic camera and lunar radar, they analyzed the spectrum, rock distribution, and shallow structure of the landing zone, and drew scientific conclusions about the morphology, material mineral composition, source and characteristics of the landing area.

For the first time, the composition of deep lunar materials was obtained directly by in-situ exploration, which led to the complex geological evolution of the other side of the moon, and especially the South Pole-Aitken basin where the probe landed last year. . It provides important evidence for the formation model and evolution model of lunar soil, as well as important reference for selecting sites for landing, inspecting and exploring future lunar missions.

Scientists have also conducted the study on the shallow structure of the lunar surface in the patrol area, which can greatly improve human understanding of the “history of lunar impact and volcanic activity” and provide new insights into their evolution.

Other results have been obtained from research into neutrons, radiation dose and neutral atoms at the lunar plane, and radiofrequency radio astronomical observation.
