At 1:30 am on December 2nd, at the Xichang Satellite Launch Center, the Long March 3B rocket soared into the sky and successfully put the Chang'e-3 probe and the "Yutu" lunar rover into orbit. It is understood that on the Long March 3B rocket, which is responsible for carrying, once again used rare earth permanent magnet devices developed by the Baotou Rare Earth Research Institute Mengxi Magnetic Industry Company. This is also the company's eleventh time to help fly the motherland's aerospace dream.

The successful launch of 　　 Chang'e-3 will realize the first lunar soft landing and lunar patrol survey, opening a new journey for my country’s lunar exploration project. The Chang'e-3, which is composed of a lander and the "Yutu" lunar rover, is expected to make a soft landing in the Hongwan area of ??the moon in mid-December. After that, the lunar rover will leave the lander and conduct a three-month scientific survey on the lunar surface, while the lander will conduct in-situ detection at the landing site. After success, China will become the third country capable of independently implementing a soft landing on the moon after the Soviet Union and the United States.

    Yang Jiayong, general manager of Mengxi Magnetics, watched the live broadcast of the launch at home, and his excitement was beyond words. In an interview with reporters, he said that not long ago, when he learned that the "Long March 3B rocket will again use the samarium-cobalt permanent magnetic radiation ring developed by Mengdi Magnetics", all employees of the company have been immersed in immense joy and supremacy. Amidst the glory, the strong sense of honor and pride further inspires the Baotou Rare Earth Research Institute to strengthen the company and serve the country. Yang Jiayong also said that my country's aerospace industry has developed rapidly, bringing together many new technologies at the forefront of the world. As a participant in the realization of China's dream of landing on the moon, we must closely follow the trend of technological development and provide more intellectual support for my country's space dream.

　　 It is understood that, from Shenzhou-1 to Shenzhou-10, from Chang'e-1 to Chang'e-3, the rare earth permanent magnet devices of Mengdi Magnetics are used on each launch vehicle. The rare earth samarium cobalt permanent magnetic radiation ring is an important part of the gyro of the Long March 3B modified rocket control platform, which plays an important role in adjusting the rocket direction and accurately entering the predetermined orbit. The ordinary appearance of the device contains countless people from Baotou Rare Earth Research Institute. The crystallization of wisdom.
