This link was in the thread: http://news.cntv.cn/2013/12/09/VIDE1386560881527612.shtmlA new animation about the Chang'e landing sequence starts at 3:26
Tonight, Chang E III detector will be under the command of ground-based monitoring system, the implementation of orbital maneuvering, from the 100 km × 100 km circular orbit, 100 kilometers into orbit by lowering × 15 km elliptical orbit. The goal is to implement an elliptical orbit track power down before the last track adjustments made before is also a soft landing.
In other news Chang'e 3 will lower its orbit to 15 x 100 km at 13:20 UTC (i.e. in 15 minutes).
Is there a shop in Beijing where you can buy these models from (And space envelopes?)I'm going Beijing soonA-P

Dozens of 1024x1024 images will be taken during descent/landing at over 10 FPS:http://translate.googleusercontent.com/translate_c?depth=2&hl=it&ie=UTF8&prev=_t&rurl=translate.google.com&sl=auto&tl=en&u=http://bbs.9ifly.cn/forum.php%3Fmod%3Dredirect%26goto%3Dfindpost%26ptid%3D11199%26pid%3D278237&usg=ALkJrhhsYaZQkQMR4du63STt__LXVUZShAThere will be something like the "6 minutes of terros" on Mars, but they will be actually more than 10: 750 seconds of authomatic flight during which ground crew will not be able to do anything [I don't understand why, being the lag just 3 seconds].http://www.chinadaily.com.cn/dfpd/shehui/2013-12/10/content_17165505.htmThe variable power engine can provide 1500 to 7500 "cattle cow" [] [Was Apollo engine variable or just on/off?]Zheng He is responsible for probe landing system.Engine will be turned off 4 meters (12 feet) from ground to prevent dust from disturbing. The four legs will absorb impact and will adjust depending on terrain slope, tolerating up to 15° tilt.http://www.chinadaily.com.cn/dfpd/shehui/2013-12/10/content_17165505_2.htmDeorbiting details:18:00 Start18:37 Chang'e3 on far side of the Moon21:20 Engine ignition21:24 Operation successfully completed, Chang'e 3 in 100x15 orbit.
dropping the last 4 feet seems risky... how does this compare to other lunar landings? I didn't think the Apollo LEM cut engines that high up at all...
Here "cattle cow" = Newtons
A cheap plastic or even paper-to-be-built model would be interesting to me.
Or the maker files for my 3-D printer. I've already made my own globes of Deimos and Phobos to go with my big Mars globe...

I didn't think the Apollo LEM cut engines that high up at all...The LEM Contact Probes were about 5 feet to signal the Contact Light and to cut engine... So its about right...http://heroicrelics.org/info/lm/lunar-surface-probe.html
