Note that in the above link, the top picture shows the spacecraft with the Moon in the background. The feature shown on the landscape is Sinus Iridium (Bay of Rainbows), an Iconic lunar feature. I don't know if this is an actual photo or if it was "assembled" from other photos, but it is very evocative.

It looks like a fully simulated view. The stars of Perseus in the background would be far too faint to show up with the same exposure as the spacecraft. |

Here's a video of rendezvous, docking, and sample transfer.

Marcin600: "Got it, Phil. Thanks for the clarification. Unfortunately, I don't have such a "trained eye" as you to notice these additional rotating sampler trenches among the scoop trenches"
This (red rectangles) is my guess as to which markings were made by the rotary sampling device, with all the rest made by the shovel. Phil

QUOTE CNSA announced that the ascent vehicle and the service module separated successfully at 0435 UTC. The SM will "select the optimal time" (择机) to return to Earth. https://twitter.com/Yeqzids/status/1335457279076757505 -------------------- -- Hungry4info (Sirius_Alpha)

Remarkable docking footage - Jupiter and Saturn are tantalisingly just off screen to the left

AmI right in thinking the crater in the background is Albategnius?

Yes, Threadworm, I was just about to post the same. Ptolemaeus and Alphonsus further back.

viewing direction is north-west -- Albategnius on R with central peak and smaller crater Klein carved into the rim. Albategnius is 130km in diameter.

I understand these are the ditches with a smooth bottom caused by a rotating tool. Earlier, I imagined that they would "drill" vertically with this head (I know the real drill is a separate tool), and here it looks like the rotary head was running almost horizontally. Am I right? Marcin |

Take a look at this video at 57:06. They show exactly how the scooping works.

Ah, was wondering how the scoops worked, they looked like thick poles on the Moon.
