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 |

An interesting tweet by Andrew Jones:
https://twitter.com/AJ_FI/status/1521102822971953152 It says Yutu 2 has now driven 1181 m. The last report was 1142 m at the end of day 41. That in itself implied a drive during day 41 of about 76 m, equal to the record set in lunar day 2. Now we have another 39 m driven in day 42, but we are currently in the local noon 'siesta' with the afternoon drives still to come. 39 m would have been a very respectable distance for an entire lunar day for most of the mission. It suggests the pace of driving is really picking up. A report from when they were approaching the 'mystery hut' said they had increased distance by taking stereo images for planning at a higher elevation angle, extending their topo map for each planning cycle, and also by shortening the noon break period, adding 2 days of potential driving. If I am misinterpreting this please let me know. Phil -------------------- ... because the Solar System ain't gonna map itself.
