A new lunar camera was born in Institute of Optics and Electronics, Chinese Academy of Sciences (IOE) for Chang’e 3. The camera is now being tested after being integrated with Lunar Satellite Payload Subsystem. It takes three years to complete the camera.

The camera is one of the important payloads of Chang’e 3, it will take 360° color images of lunar surface and monitor rover vehicle, to provide information about the rover vehicle to researchers. Compared to other cameras, it is featured in small size, light weight, low power dissipation.

The camera can work in 120℃ high temperature in the day time on the moon, it can provide high quality dynamic and static image despite the effect of varying of altitude angle of the sun on camera. The static images will be sent back directly through specific channel, and the dynamic images will be compressed to 1:20 and then transmitted to the ground. The real-time images will reach the earth within permission delay time.

China's first space science active experiment was conducted Friday morning to study the dynamical processes of the Earth's ionosphere, a top scientific institute said.

The experiment conducted at a sounding rocket launch site in Zhanzhou, south China's Hainan Province, will provide in-situ measurements for studying the vertical distribution of space environment, said Wu Ji, director of the National Space Science Center of Chinese Academy of Sciences (CAS).

The vertical exploration test was completed with the help of a sounding rocket, which released a kilogram of powdered barium into the ionosphere at a height of 200 kilometers from the ground, Wu said.

The rocket, manufactured by China Aerospace Science and Technology Corporation, carried three kinds of detecting instruments in the eight-minute flight, including a Langmuir probe, an electric field probe, and a barium powder releaser.

The CAS's Hainan Sounding Rocket Launching Site close to the equator, was established in 1986. In addition to launching sounding rockets, it deploys more than 10 ground-based space environment observational instruments.

CZ-11 looks like a quite small rocket. According to wikipedia, CZ-5 is 62 meters high. CZ-11 should be near 20 meters high. Again, according to wikipedia, dF-31 has 13 meters of length. So its probably a new rocket design, although it could still be based on an new and bigger ICBM (replacement of DF-5 ???)

Wikipedia is not a reliable source for this kind of infos :p
I think LM-5B is ~51m high.
