10. “ $\qquad$ ” was launched from China's Xichang Satellite Launch Center on December 2, 2013, entered the lunar orbit on December 6, and the "Yutu" (Jade Rabbit) lunar rover successfully soft-landed in the Sinus Iridum (Bay of Rainbows) landing area on December 14. This marks the first time a Chinese probe has landed on an extraterrestrial body, signifying that China has become the third country in the world to achieve a soft landing on an extraterrestrial body.
A. Chang'e-3
B. Chang'e-2
C. Chang'e-1
D. Tiangong-2
【Answer】A
【Analysis】Chang'e-3 is the lunar probe launched in the second phase of China's lunar exploration project, consisting of a lander and a rover (the "Yutu" lunar rover). On December 2, 2013, the Chang'e-3 probe was successfully launched into space by a Long March 3B Enhanced rocket at the Xichang Satellite Launch Center; on December 14, Chang'e-3 landed on the lunar surface, and the lander and rover separated; on December 15, the lander and rover of Chang'e-3 took photos of each other, marking the successful completion of the Chang'e-3 mission. Chang'e-3 achieved China's first soft landing and roving exploration on an extraterrestrial body, and it is one of the most technically complex and challenging space activities in China's aerospace field.

Chang'e-2 is the second lunar orbiter in China's lunar exploration program and the technical precursor satellite for the second phase of the lunar exploration project. It was originally the backup satellite for Chang'e-1, named after the ancient Chinese mythological figure Chang'e. On October 1, 2010, Chang'e-2 was launched into space at the Xichang Satellite Launch Center; on October 6, 2010, Chang'e-2 was captured by the Moon and entered a lunar orbit; on August 25, 2011, Chang'e-2 entered the L2 Lagrange point orbit; on December 15, 2012, the Chang'e-2 project was declared complete. The successful completion of the Chang'e-2 mission marked that China had broken through and mastered a large number of new core and key technologies with independent intellectual property rights in the field of deep space exploration, laying a solid technical foundation for the subsequent implementation of the "landing" and "return" phases of the second phase of the lunar exploration project and the next step of Mars and other deep space exploration, taking another important step in China's process of moving from a major aerospace power to a strong aerospace power.

Chang'e-1 is the first lunar orbiter in China's lunar exploration program, named after the ancient Chinese mythological figure Chang'e. On October 24, 2007, Chang'e-1 was launched into space at the Xichang Satellite Launch Center; on March 1, 2009, Chang'e-1 completed its mission and impacted the lunar surface at a predetermined location. The successful first lunar orbit exploration by the Chang'e-1 satellite established the third milestone in China's space industry, breaking through a large number of core and key technologies with independent intellectual property rights, making China one of the few countries in the world with deep space exploration capabilities.

Tiangong-2 is the second target spacecraft launched for China's manned space program, and it is China's first space laboratory with refueling capabilities. Tiangong-2 was launched into space on September 15, 2016, at the Jiuquan Satellite Launch Center; data services were terminated on July 16, 2019; and it was deorbited and re-entered the atmosphere on July 19, 2019, landing in the designated safe area of the South Pacific. Tiangong-2 is one of the main spacecraft in the space laboratory phase, successively docking with Shenzhou-11 and Tianzhou-1, and undertaking the important mission of verifying space station-related technologies. It is China's first true space laboratory.
