Make way for the first Mars mission! Yutu II stands by on the 18th day of the month
Beijing, June 1 (Reporter Qiu Chenhui of China Youth Daily · China Youth Daily) The reporter learned today from the Moon Exploration and Aerospace Engineering Center of the National Space Administration that during the eighteenth day of the month, the "Yutu 2" lunar rover was China The first Martian exploration mission "Tianwen 1" gave way, and with the adaptation of the ground deep space observation and control station of the "Tianwen 1" mission, the scientific load carried by the "Yutu 2" lunar rover was not turned on and was on standby.
The Chang'e 4 lander and the "Yutu 2" lunar rover completed their eighteenth day and night work at 17:00 and 7:15 on May 29, respectively, and completed the moon night mode setting according to the ground instructions, and entered the moon night sleep. In the case of limited communication capabilities, only lunar neutrons and radiation dose detectors on the Chang'e 4 lander were turned on for routine detection.
According to the news from the Moon Exploration and Space Engineering Center of the National Space Administration, at present, the renovation project of the deep space observation and control station is nearing completion. Upon completion, it will provide scientific exploration work for the follow-up scientific exploration work of the Mars exploration and Chang'e 4 project planned for July. More stable and powerful support.
According to reports, although the "Yutu-2" lunar rover did not move during the day and night, the ground science team continued to conduct in-depth research and analysis of the scientific data that has been obtained. Dr. Qian Sheng, State Key Laboratory of Remote Sensing Science, Institute of Aerospace Information Innovation, Chinese Academy of Sciences, and researchers Di Kaichang, Yue Zongyu, and their collaborators used the "Yutu 2" to measure the spectral data in place and launched the lunar soil mineral composition of Chang'e 4 landing zone Analysis and research on the effects of space weathering explored the origin and maturity of lunar soil.
The team also found that the lunar soil, which originated mainly from the spatters of the Finsen impact crater, had matured. Compared with the immature lunar soil in the Chang'e-3 landing area, the microscopic metal iron content in the lunar soil in the Chang'e-4 landing area did not change significantly with the distance between the lunar rover and the lander, indicating that the lunar soil in the Chang'e-4 landing area is fast The formation process fully mixes the most mature lunar soil on the surface.
As of May 29, the Chang'e-4 probe has been working on the moon's back for 18 months and days. The "Yutu 2" lunar rover has accumulated 447.68 meters and obtained a large amount of scientific exploration data. Among them, the lunar soil hyperspectral image and infrared spectrum data obtained by the infrared imaging spectrometer support the scientific team to obtain the fine spectrum of the lunar soil in the landing area, and provide scientific exploration data for the lunar soil's mineral composition and space weathering research.
