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 |

OK, very odd situation here. It looks like these figures in the previous post can't be trusted.
Andrew Jones tweets: https://twitter.com/AJ_FI/status/1574308716425449472 "At last, a new image from Yutu-2 on the far side of the moon. Turns out the rover was stationary for 2 lunar days (D44+D45) as BACC has been sorting out reaction wheel saturation on the Queqiao relay satellite. Yutu-2 is now in Day 46 and back on the move. " The point on my map which I showed as the 44th night was really the 43rd night. No move on days 44 and 45, and a drive on day 46 to approach a small gravelly-rimmed crater. So what was going on with the BAO site? No idea. Phil -------------------- ... because the Solar System ain't gonna map itself.
