Liftoff is schedule for 1730UTC.

CCTV International (http://english.cntv.cn/live/p2p/index.shtml) should have the live transmission of the launch.

Has a launch mass been published for Chang'e 3?   Or the mass when on the lunar surface?
I've always been crazy but it's kept me from going insane - WJ.

this paper http://tech.scichina.com:8082/sciE/CN/abstract/abstract412275.shtml includes a nice graph of the mass as a function of time during descent. I am not sure this is applicable to CE3, however, and the initial mass of 2000 kg appears to be just a convenient assumption

Some pictures of several Chang'e 3 lander/rover n' CZ-3B models on sale - apparently officially recognized by the CLEP so should be very accurate. I'll try to identify the main parts later on.....

(details here)

So how bad the situation is on lunar in-situ exploration? Well this chart sums it up.....

A handy reference of the sizes of various lunar probes. The second graph is a modified version that shows Chang'e 3 at the lower-right hand corner.

nice! however, Luna 12 is missing (it was quite different from Luna 10), as well as Hiten and Hagoromo and Ranger Block I was not really a lunar probe

According to http://news.sina.com.cn/c/2013-12-01/232528862010.shtml Chang'e 3 will arrive at lunar orbit (100x100 km at 90 deg. inclination) about 5 days after launch (according to earlier reports LOI is planned at ~02:30 UTC on Dec. 6). 4 days later (Dec. 10) the lander will lower its orbit to 15 x 100 km. Another 4 days later the "several minutes of terror" will finally come as the lander fires for landing from the pericynthion.

So this essentially means that "D-Day" is now scheduled on December 14 as opposed to December 16 as originally reported - in line with the report by ESA!   ;D
