Learned from the Beijing Space Flight Control Center: At 23:46 on January 5, the Chang'e-2 satellite, which had just successfully overflew the Tutatis asteroid, broke through 10 million kilometers under the precise control of the Beijing Space Flight Control Center. This marks a new leap in China's deep space exploration flight control capabilities.
It is understood that compared with the distance of 80,000 kilometers of near-Earth vehicles and 380,000 kilometers of Chang'e-1 satellite, this time 10 million kilometers is the longest distance that Chinese spacecraft has reached so far. Prior to this, the Beijing Aerospace Flight Control Center accurately controlled the Chang'e-2 satellite, which was the first time in the world to depart from lunar orbit and enter the orbit of the Lagrange L2 point of the solar-earth system about 1.5 million kilometers away from the earth, successfully flying over 7 million kilometers. Outer Tutati asteroid.
Zhou Jianliang, chief engineer of the Beijing Aerospace Flight Control Center, said that Chang'e-2 broke through a number of key technologies for deep-space exploration flight control, and for the first time realized and mastered the orbit design and control technology of 10 million kilometers away. The decay law and other aspects have also achieved fruitful results, which has made China's deep-space exploration capabilities have a new leap forward, and will also provide strong technical support for China's subsequent implementation of manned spaceflight, lunar exploration, deep space exploration and other space projects.
