Information about "Chang 'e I"

Chang 'e-1 is the first artificial satellite orbiting the moon in China's lunar exploration program, named after Chang 'e, an ancient mythical figure in China. 20071October 24th, 10, Chang 'e-1 was launched in xichang satellite launch center.

On March 1 day, 2009, Chang 'e-1 completed its mission and hit a predetermined place on the moon's surface.

The success of Chang 'e-1 satellite's first exploration around the moon has set the third milestone for China's space flight, and has broken through a large number of core technologies and key technologies with independent intellectual property rights, making China one of the few countries in the world with deep space exploration capabilities.

technical innovation

Orbit design technology: In order to make Chang 'e-1 take photos of the moon at any position on the orbit around the moon with the same resolution and stable orbit height, Chang 'e-1 chose the orbit around the moon pole with a height of 200 kilometers and an operation period of about 1.27 minutes. Chang 'e-1 needs the least energy to run in this orbit, and the risk of launching orbit change is the lowest, which has accumulated experience for China's lunar exploration project and the orbit design of deep space exploration thereafter.
