Chang'e-3 undergoing thermal vacuum testing

Chang'E-3 begins thermal and hard vacuum testing at the AIT Hall  facility of the China Aerospace Science and Technology Corporation in Beijing [CNSA/CLEP/CSA].

A member of the NASASpaceflight.com forum has posted a large set of photos taken during Chang'E 3 thermal vacuum testing. They are all watermarked "China Space News" which is, as near as I can tell, a Chinese magazine -- I am hoping that the gigantic watermarks make it okay for me to post them. 

I'm posting them here in the spirit of asking forgiveness rather than permission, because I haven't been able to figure out a way to ask for permission. (EDIT: Here's where the photos were originally posted online.)

Thermal vacuum testing is one of the last major testing programs that a spacecraft has to endure before it is cleared for launch. It is a test that must be performed on the actual spacecraft that is headed for space -- not on an engineering model -- and it has to be done with the spacecraft essentially completely assembled.

The Automatic Lunar Surface Exploring Vehicle, China's planned Chang'e-3 lunar rover, "a solar powered vehicle designed and built by the China Academy of Space Technology (CAST). The six-wheeled rover has a designed life of 90 days to explore three square kilometers, a total mass of 120 kg (with a 20kg payload capacity) designed to travel up to 10 kilometers."

One of the missions planned for launch this year is China's Chang'E 3. I had never paid any attention to Chang'E 3 until this week, so I had no idea how large or ambitious it is. Chang'E 3 is a 1200-kilogram, RTG-powered lunar soft lander with a 1-year nominal mission lifetime. On top of that, it includes a 100-kilogram rover equipped with cameras and APXS. The rover has a nominal lifetime of 3 months and range of 10 kilometers. Wow. Here's a cool artist's concept that Glen Nagle put together. Enjoy it -- this is the first time it's been published!

China announced late in 2011 that Chang'E 3 would be a lunar soft lander, to launch in 2013. Computer animations played on Chinese TV around that time (go to the 30-second mark) showed a lander deploying a smaller MER-like, solar-powered rover, with six basket-rimmed wheels and two pairs of cameras on a mast. It is expected to land in Sinus Iridum, an area well surveyed by Chang'E 2.
