UHF Satcom ‏@uhf_satcom 2月22日
Another quick FFT of Yutu Rover X-Band downlink - nothing detected from Chang'e'3 lander or 7GHz uplinks.

UHF Satcom ‏@uhf_satcom 2月22日
Yutu Lunar Rover is back in town! A massive signal on 8462.053MHz complete with sidebands, maybe low-rate data.

UHF Satcom ‏@uhf_satcom

Nothing again tonite on X-Band from either the Yutu lunar rover or the Chang'e'3 lander - will check again tomorrow!

-------------------------------------

The same (very useful) source detected nothing last month as well. Note that the negative result only applies to the specific times of monitoring, and there may have been activity when uhf_satcom was not facing (or listening to) the Moon but China was in contact.

中欧深空探测研讨会在北京召开
发布日期:2015年07月14日 字体:【大】【中】【小】
  2015年7月9日至10日,中国国家航天局与欧洲空间局在京召开中欧月球探测研讨会,会议围绕嫦娥四号目标任务和有效载荷搭载进行了讨论。
  会上,欧洲空间局相关专家提出利用嫦娥四号搭载月震仪、快闪相机、激光反射器等载荷的建议。经商议,双方初步确定将月震仪和快闪相机等四个有效载荷纳入合作范围。欧洲空间局负责协商欧洲载荷以及其总成与接口,中方通过双边航天局长会晤推动建立载荷研制国技术团队,争取在2018年提交正样。
  来自法国巴黎索邦大学、瑞士苏黎世理工、澳门科技大学以及中国国家航天局探月与航天工程中心、中国科学院、北京大学、中国科学技术大学、中国地质大学等单位的专家学者参加了会议。

Preliminary Suggestions for International Cooperation on Chang'E-4 Lunar Probe
Xu Y. (China)
http://www.unoosa.org/pdf/pres/copuos2015/...2015tech08E.pdf

An Introduction of Chang’E-4 Probe:
Probe(Lander,Rover)+ Relay Statellite
Soft-landing on lunar farside
Landing and roving exploration
Will be launched between 2018 and 2019

the probe:
Chang’E-4 probe,lander and rover have the same technical status with the Chang’E -3; but exploration will be redesigned; the payload will be reconfigered; The name of the probe might be changed.
Chang’E-4 probe is a backup spacecraft of Chang’E -3 probe. By now, all platform products of the probe have been manufactured, waiting for further AIT.
The probe will be launched by a long March 3B rocket from the Xichang Statellite Launch Center(XSLC) which is the same way with the Chang'E-3 between 2018 and 2019

The relay statellite:
will be first launched into a lunar transfer orbit about the end of 2018 in the whole mission, then starts its earth-to-moon jurnery alone, and will enter and run in a Halo orbit around the Earth-Moon L2 point; the design life is 3 years.
would provide relay service for the probe and the Earth, and carry out exploration.

Engineering objectives are as follow.
To realize the first soft landing on the lunar farside and perform exploration in human history.
To demonstrate technologies of lunar data relay, landing and roving on complicated terrains of the lunar farside, and lunar night power generation;
To perform further detailed survey on lunar environment in order to lay a foundation for subsequent lunar exploration mission.

Tentative Scientific objectives are as follow.
To study lunar surface dust features and its formation mechanism;
To perform in-situ measurement of lunar surface residual magnetism
and study its interaction with solar wind;
To study lunar surface temperature and particle radiation environment;
To perform lunar surface topology and material composition analysis,
shallow-layer structure survey and study;
To explore and study lunar interior structure of spheres;
To perform lunar based VLF astronomical observation and study

I can't find an English-language source for this so far, but I'm very curious about the trajectory of the 'skip' that it did before reentry. Where did it execute this maneuver (i.e., over what part of the Earth)? Wondering how far it skipped.

他表示,嫦娥五号的主要任务是去月球取样,并把样品拿回来。也就是完成探月工程“绕月-落月-返回”三部曲中,最为艰巨的“返回”任务。嫦娥三号“落月”地点位于虹湾地区,而嫦娥五号则准备在风暴洋附近。两者相距非常远,不会产生交叉。
Chang'e-5 will be landed in the Oceanus Procellarum

I think Chang'e-4 will also landed here

According to this story, the Chang'e 5 prototype will be an orbiter and will be called Chang'e 4. It is the backup for Chang'e 3 that has been "adapted to verify the technologies needed for the Chang'e 5 mission". Well, it looks like the Chinese won't send another rover as a follow-up to Chang'e 3. Too bad, from a lunar surface exploration point of view.


Chang'e-5 pathfinder will be launched in october, it may be called Chang'e-5 T1(test?)
Chang'e-4 will be launched in 2016, it will another rover ,while added a sample arm, verify the lunar sample technology for Chang'e-5

a paper have been published in copuos2014:
Chinese Lunar Exploration Program
http://www.oosa.unvienna.org/pdf/pres/copuos2014/tech-06.pdf

something about Chang'e-3:
During the day time of the first 4 months, the Lander got 118.5GB original detecting data.
Extreme ultraviolet camera:Obtained more than 600 images in total.
Lunar-based astronomical telescop:Observe the brightness and variances at near-UV band for various celestial bodies. Up till now, more than 32,000 images have been obtained.

The Patroller (Yutu) got 32GB original detecting data

current status:
The 6th moon night by May 23
The Lander is proper functioning
Patroller(Yutu) encountered control fault, part of the loading works normally
Under the abnormal condition and the extreme low temperature, the
patroller(Yutu)’s performances are gradually degenerated

对于“嫦娥”“玉兔”来说,这次日食发生时,它们才从月夜中唤醒没多久。仿佛刚到上午,天又黑了。杨宇光说,由于探测器所处区域被地球阴影覆盖了几个小时,会出现温度骤降的情况。但“嫦娥”“玉兔”原本就是按照月昼、月夜两种极限工况设计的,应对这样的温度不会有太大问题。
此外,日食期间探测器供电系统失去了太阳能,杨宇光认为,为避免出现能源问题,可以采取不做动作、关闭科学载荷等方式降低能耗。“就好比让‘嫦娥’‘玉兔’打个盹,睡个‘回笼觉’。”他说。
据悉,“嫦娥”“玉兔”已安全度过这次考验。
