2) After all the investigations and images of Sinus Iridum by Change'2 and the pre-released information for Change'3 by Chinese, why did they decide to land at least one (if not two) revolutions earlier - thus landing in Mare Imbrium ?

That would be fantastic!Amazing video stitched from images from the descent camera! http://news.cntv.cn/2013/12/15/VIDE1387092680807230.shtml(will try to get it to Youtube later)

Couple of questions that are "niggling" me :-1) On rover deployment . was the Yutu "pushed" to the ramp before lowering OR did it roll to the ramp before it was lowered. Certainly discern wheels rolling once on ramp but I could not decide whether they were rolling while it moved from top Change'3 platform ?
But I expect Chang'E 4 to land on the other unit, actually in Sinus Iridum.
Talking of Chang'e 4, will that be that launched on the same launcher as this one or are they going to put it one of their new launchers? Afterall to do sample recovery I would think they'll need a higher capacity launcher.

Thank you for the direct link!!

Certainly discern wheels rolling once on ramp but I could not decide whether they were rolling while it moved from top Change'3 platform ?It was commanded to drive. Three separate commands. It's in the video on Emily's blogpost covering this.I'm wondering about the mechanisms they had to prevent the rover from rolling off the transposition mechanism..especially since the rails pitch downward for some time, until the lowering is fully complete.Did the rover energise all 6 wheel driving motors as brakes? (i.e. since the wheels can be driven in forward or reverse, energising the coils to the point just prior to inducing reverse motion) The wheels themselves are mesh..so was there some stop-spike that allows rolling translation (blocked by the brake) but prevents sliding?Or was it all just static friction, and carefully chosen materials?
If the current color balance is correct (and the Chinese flag color looks correct to me) this dark chocolate lunar regolith reminds me of the Apollo 17 site.

That footage is incredible. I so wish we'd had something like that for MSL!

the landing video is now more conveniently on Youtube
