The highest resolution map of the moon in the world will be published on Monday. That’s according to China’s National Defense Technology Industry Ministry.
China´s second moon orbiter, the Chang´e-2, has sent back its first batch of data while orbiting the second Lagrange Point (L2) about 1.7 million kilometers away from Earth.
Chang´e 2, China´s second lunar probe satellite, has successfully entered deep space.
Chang´e 2, China´s second lunar probe satellite, has successfully entered deep space - at a distance of 1.5 million kilometers from earth.
The Chang’e-1 was firstly launched into the transitional orbit close to the earth, and then sent to the earth-moon transfer orbit after several adjustments, but the Chang’e-2 will be directly sent by the rocket to the earth-moon transfer orbit... Detail >>
The Chang’e-2 will test the 100 kilometers × 15 kilometers orbit changing and fast orbit measuring technology. The Chang’e-2 satellite’s ability of changing its round orbit with a radius of 100 kilometers into an elliptic orbit with a perigee of 15 kilometers and an apogee of 100 kilometers from the moon will be tested...

Compared to the S Frequency Range Satellite Measurement and Control Network adopted on the Chang’e-1, the X frequency range radio communication equipment has higher signal frequencies and is more effective for long-distance communication... Detail >>
The Chang’e-2 will be equipped with a landing camera, and its imaging capacity for the moon will be tested in order to make preparations for the soft-landing of the Chang’e-3. The data transmission speed will also be increased from 3 million bytes per second of the Chang’e-1’s to 6 million bytes per second on the Chang’e-2... Detail >>
The Chang’e-1 was captured by the moon at a location 200 meters away, but the Chang’e-2 will brake and be captured by the moon at a location 100 meters away. The Chang’e-2 will have a higher speed, lower orbit and larger momentum, and meanwhile the uneven lunar gravity field will have a heavier influence on the satellite orbit... Detail >>
The range resolution of the CCD camera carried by the Chang’e-1 was only 120 meters. But the camera on the Chang’e-2 will carry out imaging experiments with range resolutions superior to 10 meters and five meters in the perigees of the round orbit with a radius of 100 kilometers... Detail >>
The Long March 3C (CZ-3C) is a large three-stage liquid strap-on carrier rocket. It consists of a CZ-3A, which is used as the core-stage after being modified, and two liquid roll boosters. The CZ-3C is one of the Long March 3 series carrier rockets after the CZ-3A and CZ-3B. It is almost the same as the CZ-3B in terms or their structure and subsystems, except for two roll boosters tied on the first-stage. The launch of the CZ-3C has broadened the scope for users to flexibly choose the Long March rockets according to the quality and mission of the payload...
Chang´e, originally known as Heng´e or Heng-O (姮娥), is the Chinese goddess of the moon. Unlike many lunar deities in other cultures who personify the moon, Chang´e only lives on the moon.
