Would you look at that...

Not surprising... see this link for pictures of Apollo 11 and 16 regolith samples showing 1-2mm impact-glass spherules.

I did not know that, thanks for digging that up! Still mesmerizing, and these appear substantially larger by a factor of >10x...

Glass microspherules are ubiquitous in lunar regoliths. A better analog of the Yutu 2 spheres is the pair of glass balls, each several centimeters across, returned by Apollo 16.

Search for 'glass sphere' in the Apollo 16 Preliminary Science Report:

https://www.hq.nasa.gov/alsj/a16/a16psr.html

The samples are 60095 and 65016.

I saw those, but they were so large that I thought they might have come from a large rock that had been "turned and polished" somehow for some scientific study...

I agree. BTW regolith, like sheep is its own plural.

Phil Stooke · « **Reply #486 on:** 03/07/2022 03:02 am »

yes, I should have said regolith samples.

Some info on CE-6 and CE-7, as well as Mars sample return plans:

Yutu-2 and Chang'e 4 has completed its 44th lunar day mission, they went to sleep for the 44th time on 07/05/2022 7:14PM and 07/06/2022 6:06 AM Beijing Time respectively. The rover has traveled 1239.88 meters since landing.

Yutu-2 studies the South Pole-Aitken basin:

Blackstar · « **Reply #490 on:** 11/25/2022 01:02 pm »

As a reminder (because I need a reminder):

CE-5 already flew and was a sample return mission.
CE-6 is due to fly in the next couple of years, and will be a sample return mission to the South Pole Aiken Basin.
So these slides detail CE-7 and CE-8.

Yutu-2 is still alive and moving

Finally, official update of Yutu-2 Rover on the fourth anniversary of Chang'e-4 landing on the far side of the Moon: surveying distance passed 1455m. Previous update was 1300m in September of 2022. But, still waiting for the release of new lunar images and the map of driving.

These data releases happen once per month. See here:

https://moon.bao.ac.cn/

('bao' is the Beijing Astronomical Observatory)

You can register as a user and download data including science images, and there are many other things to explore on that website including press release images.
