Shock: Chinese Chang'e II came the shocking news!

If you live in Chang E 2 probe asteroid, pay attention to control the the hall large screen digital will find, Chang E 2 now ground speed is less than one kilometer per second, but he is unlikely to return to Earth. Because he has long been out of the Earth's gravity. Become a satellite of the sun, along the outer concentric circles orbit close to Earth's orbit around the sun, the relative speed of the sun faster than the speed of revolution of the earth, at least 30 kilometers per second.

Beijing at 10:18 on the 28th, the success of Chang'e II satellite and the distance between the Earth exceeded 20 million kilometers, the Chinese lunar and deep space exploration, the ability to achieve a new leap. Currently, satellite status, the flight control events perform normal, Chang'e II satellite is continuing to further deep-space missions.

According to reports, since its launch in October 2010, Chang E II from the moon 380,000 kilometers away from the ground, to 1.5 million km from the Sun-Earth Lagrange L2 point over the detection of asteroids from 7 million kilometers to exceeded 10 million kilometers, and then to break through 20 million kilometers ... extended service nearly two years of Chang'e II satellite, in the vastness of space constantly refresh "China attaches. Meanwhile, the "Chang'e II" 7 million kilometers deep space successful close flyby and to intersection detection the international No. 4179 of Tutadisi asteroid, the asteroid image obtained a resolution of 10 meters for the first time in the world.

Wu Weiren, chief architect of China's lunar exploration, scientific planning, zero-window launch innovative track design, precise measurement and control, maximize savings in satellite fuel to ensure that the "Chang'e" Space Expeditionary trip abundant energy. To continue in the future to carry out tracking Chang'e II monitoring and control, and strive to control satellite to keep the distant deep space, deep space monitoring network more fully comprehensive test validation. Meanwhile, we should seize the time to carry out a system-wide technical summary of the Moon II mission, to further deepen the scientific research, more achievements.

2013, the second half of China's lunar exploration program will to usher in the shoulder "sangrakwol task Chang E III detector first extraterrestrial celestial landing.
