A lower orbit now: http://spaceflightnow.com/2015/01/21/chine...in-lunar-orbit/
Images of the potential sample return landing sight coming in April, apparently (but nothing yet on where).

Suggestions have been circulated that the region will be Oceanus Procellarum. I have suggested that the most likely area would be the area of the youngest known mare basalts (determined from crater counting), south of Aristarchus. This is (one of the top scientific targets on many lists as it shows how long mare volcanism continued. A secondary goal would be Aristarchus ejecta, and a tertiary goal would be ejecta thrown off the nearby Aristarchus Plateau.

Leonard David has posted this visualisation of the Chinese sample return mission taking off from the moon.
It fits very well with the design drawing shown in Post #9 in this thread. It also lays to rest the older design portrayed in Post #8.

News that the Chang'E 5 T-1 test vehicle, still orbiting the moon, began imaging potential landing sits in May. No images released yet.

Google translation:
----------------------------
May 28 15:10 pm camera power is first applied a test shot, successfully shot two minutes of the Earth video, get a clear image of the earth. After the implementation of the third lunar imaging, to obtain images of more than 3,000 frames, good image quality.
The imaging camera to obtain a 2.5m resolution images of the lunar surface, indicating that the camera is operating normally in orbit long for the subsequent expansion of tasks carried out to provide a strong guarantee.

Was the full mosaic in this article released already? I seem to recall only seeing the single frame with Earth and the lunar far side visible.

CE5T1 completes imaging CE5's landing zone: http://news.sina.com.cn/c/2015-09-02/203732269747.shtml (Chinese)

The resolution is said to be 1m/pix. CE5T1 also verify the techniques needed to control the ascending module and service module.

One way to interpret the Chinese text is that this imaging from 30 Aug. to 2 Sept completed the imaging of the fifth potential landing site. I don't know where any of them are yet - if anyone knows please let me know. But nice to know there are five candidates.

EDIT - the more I think about it, the more I suspect that the 'fifth' referred to is the fifth spacecraft, Chang'E 5. Google Translate is a blunt instrument for probing difficult questions. There might only be one site after all. I hope we will learn more soon.

EDIT AGAIN - a bit of detective work. The terminator was crossing the Mare Crisium area over the few days the images were taken. I had been expecting a landing in Oceanus Procellarum, but the sun would have been overhead there, and these images have shadows suggesting a lower sun elevation. Possibly a site in the eastern maria, but west of Crisium. Not much to go on yet.

there is also a release in English here: China's lunar orbiter gets close-up pictures of the Moon
it is clearly stated that the orbiter imaged the landing site of CE-5

Is there anything that indicates whether Chang'e 5 T1 is being used to image the potential farside landing site of Chang'e 4?

Came across this July 29 item on the CAST website having something to do with a "3D mode" for a Chang'e 5 camera, but I can't make heads or tails of the Google translation.

Phil -- I believe the "fifth" indeed refers to the fifth probe in the Chang'E series. And it is from a verified source that CE5 will land in Oceanus Procellarum: http://news.xinhuanet.com/tech/2014-09/04/c_1112367913.htm (Chinese).

It is about a documentary film or something -- they take the film in 3D. Nothing to do with CE5 or CE5T1 the probes.

AGU abstract - it says the landing site is in the northeastern part of Oceanus Procellarum.
