Sometimes it is useful to consider USSTRATCOM data as a "suggestion".

An update: Apparently Chang'e 3 is working well. December 3 correction, that everyone was asking, has been completed successfully. A third correction isn't needed.

Phew, they went very quiet for a while there.

I wonder if ESA tracking is able to interpret the basic telemetry data or is it opaque data stream to be forwarded to Beijing for them ?

So Spaceflight 101 said the LOI was on Dec 6 at 2:30 UTC. More recently Zarya says 9:30 UT based on 112 hour flight time.

Chinese reports are now reporting that LOI will happen "this evening" local time, which fits more with Zarya's version.

Guessing the Chang’e-3 trajectory [Where is Chang'e-3 now]: http://astrogatorsguild.com/?p=1122 by Mike Loucks, one of the LADEE navigators, uses available public info to see whether he can come up with a trajectory that makes sense (spoiler: he can). He uses the 9:30 UTC time for LOI, referring to Zarya.

I think there is a translation error in this report. it should be "7500 newton" instead of cattle cow

There are lots of funny mis-translations like that in Google, especially for Chinese and Japanese (I remember Hayabusa's name was always translated by Google as "It is quick the").

There is a word, “落月” that keeps showing up in Google translations as "sangrakwol", which is meaningless. Can anyone say what this actually means in the context of Chang'e? It is found in the second paragraph of this article: http://tech.sina.com.cn/d/2013-12-02/02398965861.shtml

A literal translation is "descend to the Moon", so it means lunar landing.

Latest news!

http://bjrb.bjd.com.cn/html/2013-12/02/content_130362.htm

LOI burn planned in just under 2 hours from now, at 09:50 UTC.

Lunar landing is planned at 15:22-15:35 UTC on December 14.

The rover should be deployed from the lander at 20:38-22:21 UTC on the same day. Then some time within the communication window on December 15 at 07:21-15:38 UTC, the lander and rover will photograph each other ~~and sing Moon River together during dating~~.

Waiting for news on the lunar orbit insertion, which should have happened by now...

CCTV13 reports from Beijing MCC and 9ifly says braking was successful.

Nighthawk · « **Reply #594 on:** 12/06/2013 09:13 am »

The retro burn of the main engine lasted for ca. 360s and the probe was successfully captured by lunar gravity. (via CCTV news). The lunar orbit is a circular orbit 100km above surface, without any temporary elliptical orbit.
