How much of the mass launch in the commercial sector is for Starlink space junk? What the hell is even Spaceship?
In total, 989 Starlink satellites were launched out of 19 launches. From the total of 19 SpaceX launches, 15 launches of the Starlink v1.0 satellites which have a weight of 260 kg were carried out, totaling a total of 785 satellites, which would be a payload of 204,100 kg or 204 tons.

The remaining 4 launches placed 204 Starlink v1.5 satellites into orbit which have a total weight of 295 kg, totaling 60,180 kg or 60 tons.

The numbers in terms of payload are even more impressive, because the total launched load reaches 264.2 tons, that's almost the total of 266.9 tons that were launched from the US commercial segment, the rest comes to 2 .7 tons, if not for SpaceX with the Starlinks, China would have launched almost 4x more payload than the Americans.

The term SS(Spaceship) should definitely encompass the payload launched to space stations, it is not uncommon for large launches for space stations, the ISS needs to be refueled every 45 days, which guarantees a total of 8 launches per year, putting a total of 3 tons per launch, that's a total of 24 tons of payload for the ISS annually.

In the Chinese case, here is an example:

The photograph was taken by a device released by Tianwen 1. After capturing the images, the device sent the photos to the probe via Wi-Fi. The images were published by the China National Space Administration and show Tianwen 1 above Mars, with its platforms and solar panels.

The photographs were taken by a small camera device released by Tianwen 1. After capturing the images, the device sent the photos to the probe via Wi-Fi. The images received a lot of attention on social media, specifically by engineers from others space agencies that usually photograph Mars.

SpaceX launched 17 groups of Starlink satellites with a total tonnag of 257.6t in 2021.

They are independent and maybe harmful for other space launches and orbitors, but they are not junk but commercial assets.

The world need a new regulation to coordinate and administer satellite launch activities.

Any moon-hut fan here? Look like you'd be disappointed

I was not.

When they say they were going to investigate this odd looking object when there are hundreds more odd/anomalous looking "rock debris" in the Chang'e 3 landing site which they seemingly just ignored without even commenting about it, I was already quite sure what is expected to come for this case, clearly made up to be "mysterious".

Why are China's space images always much lower resolution than the images provided by NASA? The images from their rovers are likewise very disappointing. It almost sems like it would be better if they didn't release the images at all because they suffer so much from the comparison. I can understand that they are much newer to the game, but is it really such a challenge to do imaging in space or on another planet? Is it not just a matter of using a larger sensor? Just asking out of curiosity...

it's a throw away selfie camera, physically likely something akin to a laptop camera for low weight. they did it more for fun than any real scientific purpose.

remember the cost of sending anything to Mars is likely $/gram.

I once read that all photos taken in space are all black and white, then they are converted and colored. But I definitely don't agree with this assessment that all photos released by China have a lower resolution than the American counterpart, I've seen some NASA photos of Earth and the resolutions are quite deficient.
