IT Home, Aug. 25, Chinas lunar exploration engineer announced recently that the long-silent Change 4 lander and the Jade Rabbit 2 patrol passed the lunar night cryogenic test again, waking up at 8:10 on Aug. 25 and 8:42 on Aug. 24, respectively, and entering the day of September.
Subsequently, the lander will launch the payload lunar neutron and radiation dose detector, low-frequency radio spectrum detector, the inspector payload panoramic camera, lunar radar, infrared imaging spectrometer, neutral atomic detector and so on during the day of this month, and continue to carry out scientific exploration tasks, including the morphology of the lunar surface, material acquisition. The composition and shallow surface structure of lunar science data.
The environment of the moon is different from that of the earth. A months night is equivalent to more than 14 days on the earth. At the same time, the lowest temperature can reach minus 180 degrees Celsius under the condition of moonlight. Therefore, in order to protect the equipment from low temperature damage and long-term lack of light, the scientific research team divided the lunar mode of Change-4 probe into the lunar day working mode and the lunar night dormancy mode, the combination of work and leisure. The autonomous wake-up of the lunar rover actually tests the reliability of the equipment.
At 10:26 on January 3, 2019, the Change-4 probe successfully landed in the pre-selected landing area near 177.6 degrees east longitude and 45.5 degrees south latitude on the back of the moon, and transmitted the worlds first close-range photograph of the back of the moon through the Magpie Bridge relay star. The mission achieved the first soft landing on the back of the moon and the first relay communication between the back of the moon and the earth. On January 11 of the same year, Change 4 lander and Jade Rabbit 2 patrol vehicle completed mutual shooting, marking the success of Change 4 mission.
