I have just been reviewing all of the animations of the Chang'e 3 mssion which I can find online - mainly at YouTube - and all of these depict a direct return from the lunar surface, like the Luna sample-return missions.So, was the Chinese article wrong in what it said about a rendezvous in selenocentric orbit or have the Chinese decided the re-design and complicate the mission profile in the last three years or so?
Since the Chinese originally announced Chang'e-1, Chang'e-2 and Chang'e-3 as being the lunar orbit, lunar landing/rover and sample return missions respectively, there is plenty of room for confusion since Chang'e 3 will be the first rover mission!Maybe we should think of the original designators as being Phase 1, Phase 2 and Phase 3 respectively, with the flown Chang'e 1 and 2 being the Phase 1 missions and Chang'e 3 (and Chang'e 4? - even Chang'e 5??) being Phase 2 missions.
I have seen it reported as an RTG, not as RHUssee for ex http://www.dragoninspace.com/lunar-exploration/change3.aspx
