Thanks for the link!
Interesting but quite complex mechanism (lots of moving parts and movements). Now I know how the shovel works! (animated gif)

Unfortunately, there is no simulation or video of the operation of the rotating head - so I still do not know what its working position is (vertical or horizontal)...
But I suppose it's vertical(???). I also did not know that this head has something like "rotary knives"! (picture)

Though they would be completely invisible when exposing on the sunlit spacecraft.

Another interesting solution is the transport of samples from the drill to the container - from what I understand it is a very long, flexible tube-rope!

That's pretty similar to what they did with the USSR Luna missions in the '70s.

re: Jupiter, the visibility of a small "point" object is in large part determined by whether or not it fills the area of a pixel or not. The surface brightness of Jupiter is about a quarter that of the full Moon, and brighter than that of the Moon near the terminator. If a pixel is filled by Jupiter then that pixel should be readily visible vs. the black of space. If Jupiter fills only, say, 1/10th of a pixel, then it certainly won't. So magnification is a key factor in making Jupiter visible in the background.

Well, judging from the size of the Earth in that video Jupiter would cover a very tiny fraction of a pixel.

it's explained in this paper
A Spiral Seal Method in the Lunar Regolith for Chang’E-5 Drill: Seal Design and Experiment

and the scoop is described in detail (but alas in Chinese) in this paper:
Design and test of a sampler for lunar surface regolith

Paolo, thank you for the link to the article on drill sampling. It explains a lot
But I cannot open the second article about the scoop. I get a download error every time. Is there any other source?

it works for me, but the site is often shaky and you may need to retry later.
otherwise you can try here http://zgkj.cast.cn/EN/abstract/abstract11062.shtml
I don't know if it would be ok to post the paper here

Despite many attempts, it does not work for me (only abstract). Maybe I'll try in a while...

Edit: And it finally worked! Thanks a lot!


Oh, so the same sampler’s head can be used "for digging up the lunar regolith" - just like in the animated gif posted by me; or in the "upside down" position - "under working mode of shovel” !
This probably complicates the case of the tool marks on the Moon - increase them to 3 types!

Golden ten data
32 minutes ago from Xiaomi 9
[ #Chang’e五号升器控落月# ] The reporter learned from the National Space Administration that at 6:59 on December 8, the Chang’e 5’s ascender was de-orbited in accordance with ground instructions and landed on the moon at around 7:30. A planned landing point near 0 degrees longitude and 30 degrees south latitude. Experts from the National Space Administration's Lunar Exploration and Space Engineering Center said that the Chang'e-5 ascender has successfully completed its mission. The controlled deorbiting and landing of the moon can prevent it from becoming space junk and avoid affecting the subsequent lunar exploration missions of the international community. This is China's responsibility. Major powers make important commitments to mankind's peaceful exploration and use of space. (Voice of China) #嫦娥五号#

There were rumours earlier without good sources, but this seems more reliable. For 'landing' read impact.

I have updated my moon sites map with the new locations.

Thanks, Phil, that's a very handy map. Do we get extra points for identifying where the background border image is?

Not only extra points, I will buy you a Timbit.
