Some of the features I know from the Chinese space station - Solar panels smaller in area than ISS but produces similar amount of power, indicating much more efficient solar panels - Ion thrusters to keep space in orbit - Automated docking of cargo and crew capsule. Semi-automated docking of large station components like the 23ton labs - A robotic arm similar to ISS that walk along the joint points on the station. It…

So then maybe a little late to sanction their tech to keep them from being peer competitors.

That's way too broad, because it depends what it is. Surprisingly, it seems to be easier to build a space station than to compete with Boeing and Airbus.

Sanctions didn’t stop China from carrying out one of the most successful research and technology exfiltration campaigns in history.

Kind of ironic? https://en.wikipedia.org/wiki/Operation_Paperclip

I assume I’m getting downvoted in the parent because there’s some implication that I’m judging them for it?

But I’m not. I was simply saying that the sanctions have nothing to do with their ability to obtain western tech.

You say you're using iOS Safari. I'm interested to know how you were able to configure it to delete navigator.geolocation, apparently without realizing what you were doing. I don't plan to support a broken configuration like that, but if you can figure out the cause then I could file a WebKit bug on your behalf.

Why would it be on OP’s behalf? If it’s just a configuration that WebKit supports it’s either violating the standard or you’re not handling it correctly on your site. It has nothing to do with the OP at that point.

They are the one experiencing the bug. I can't file the bug because I don't know and can't investigate the cause. If they are experiencing an issue, and they find the cause, they should file the bug. But they probably won't bother, seeing as they'd rather blame me. I'm willing to file it for them, and that's probably better anyway as I have WebKit committer status. Bugs filed by me may have more weight as I have filed and fixed many before.

The sanctions are pretty irrelevant when China has one of the best hacking groups in the world and every US corporation of relevance is strongly connected to the Internet.

Yeah, because they are only this advanced because they stole US technology. Chinese people can't be as intelligent as american.

Does anyone know to what extent China has advanced the state of the Soviet technology that they have (I assume) licensed? I have been to the Russian Star City training facility, Baikonur Cosmodrome and been in the full-size Mir training module and the Chinese station components look very similar. I am sure getting good information is difficult, but perhaps someone here has some more info.

The co-orbit strategy is excellent, a short trip for repairs and easy to fit into existing schedules if something goes wrong. It's no James Webb but was never intended to be, about the same size as Hubble but with 400x the field of view. Guessing it will be cranking out the discoveries.

Thanks for the super informative reply. I am hoping as there is more activity on the space station, that more information will be coming out. It would be nice to be able to see something similar to the ESA, NASA and even Roscosmos launch feeds and Q&A sessions.

While I too look forward to that day, at least for awhile longer due to physics, we are going to continue to have “rounded cylinders”. The main reason for this is very simple: Pressurized vessels. If you look at any type of air tank, and there is a reason they are a certain shape. The moment you do any type of “point” or “edge” it becomes a weak point in the design. That said… you can always make a really large press…

A torus shape has no sharp edges and can be pretty useful in space if it rotates.

Absolutely, but now you are talking pretty large structures… which will take time for us to get there.

Wait, in order to build this, they've launched half a dozen rockets up with no idea where the boosters would come back down and land? That seems up there amongst worst ideas I've heard for a while, "good luck everybody else." Edit: didn't realize this would be a controversial comment; per the article, the "norm" is to have a burn again after releasing their payload, to "control" / direct the return. The Chinese aren'…

But still paying if something happens.

from a mechanical engineering standpoint, a torus is also easier to construct than a sphere.
