Based on the data of the panoramic camera stitched images and DOM images on the 22nd day, the “Yutu-2” lunar rover travelled to the basalt distribution area and the impact crater area with higher reflectivity during the 23rd day. Both locations are Located northwest of the lunar rover. In this travel route, the infrared imaging spectrometer performed a spectral detection of a rock block with a diameter of about 30 cm. The scientific research team is conducting in-depth research on the detection data. During the 23-month scientific exploration, the lander’s lunar surface neutron and radiation dose detector carried out the world’s first on-site- on-site particle radiation environment detection on the lunar surface, and obtained precious first-hand scientific data. The research results are in Science Advance Journal published.

The moon surface neutron and radiation dose detector can comprehensively measure the total particle radiation dose, neutral particle radiation dose, particle radiation LET spectrum, neutrons, and charged particles on the moon surface. The actual measurement results show that the particle radiation dose rate near the landing zone is 13.2uGy/h(si), the dose equivalent is twice that of the surface of Mars and the interior of the space station, 5 to 10 times of a flight, and 300 times of the surface of the earth (Beijing).

The measured monthly radiation dose (the horizontal axis is Universal Time, the vertical axis are respectively: a total radiation dose rate in silicon (microGray/hour), b. neutral particle radiation dose rate in silicon (microGray) /Hour), c. The charged particle radiation dose rate in silicon (microGray/hour), d. The cosmic ray penetrating particle flux (pieces/square centimeter·hour·radian) measured monthly surface radiation dose (horizontal The axis is Universal Time, and the vertical axis are: a total radiation dose rate in silicon (microGray/hour), b. neutral particle radiation dose rate in silicon (microGray/hour), c. silicon Charged particle radiation dose rate (microGray/hour), d. Cosmic ray penetrating particle flux (pieces/square centimeter·hour·radian)

These field measurement results provide important radiation environment parameters for the follow-up lunar exploration in my country. The load also distinguishes the radiation dose of charged particles and neutral particles, thereby providing more accurate radiation physical quantities, which can serve the radiation protection of future astronauts.

Today in the history of spaceflight on 24th October :

On October 24, 2007, my country’s first lunar exploration satellite, Chang’e-1, was successfully launched by the Long March 3A carrier rocket at the Xichang Satellite Launch Center, opening the glorious course of my country’s lunar exploration project. On November 12, 2008, the full moon image taken by Chang’e-1 was released. On March 1, 2009, the satellite hit the moon in a controlled manner as scheduled. The successful implementation of this mission marked my country’s entry into the world deep space exploration club and established the third milestone of China’s spaceflight after artificial satellites and manned spaceflight.

On October 24, 2014, my country’s first-month high-speed reentry aircraft was launched from the Long March III C-modified II carrier rocket at the Xichang Satellite Launch Center, and it orbited the moon three days later. On November 1, the returner landed in Siziwang Banner, Ulanqab City, Inner Mongolia, China. As a pilot mission of the third phase of the lunar exploration project, it verified the key technology of lunar sampling and returning, laying a solid foundation for lunar sampling and returning.
