- [Joe, China] Go visit our fairy Chang´e who live on moon for centuries. A pleasant journey I wish. Next time, we take her home.
- [Joel Raupe, U.S.] Go confidently, tightening down the delicate orbital maneuvering necessary for future excellent Terminal Descents. Share your future landing target candidate locations.
- [Ping, UK] Exciting times ahead for science ( especcially for chinese all over the world). Safe journey Chang´e 2 !!! ... ...
- [Maurice Collins, New Zealand] ...have a great flight Chang´e 2 on your mission to the Moon. I look forward to seeing the returned images!
- [winston, Canada] Good luck, China and Chang´e 2, on a successful flight and mission. My hopes and prayers go with you!

Key Technology Innovations
[First] Sending a satellite directly into the earth-moon transfer orbit will be realized
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 >>
[Fourth] Test the 100km× 15km orbit changing and fast orbit measuring tech
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... Detail >>
[Second] Test of X Frequency Range Deep Space Measurement Control Tech...
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 >>
[Fifth] Test of the brand-new landing camera, which has a much stronger data transmission capacity
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 >>
[Third] Test tech of landing a satellite on the moon from an orbit of 100km
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 >>
[Sixth] High definition imaging experiment for the pre-selected landing area of the Chang’e-3
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 >>
