Unfortunately it’s about $2,720 per 2.2 lbs in even the best case scenario.

You are allowed to say kilogram on the internet.

You're also allowed to say 2.2 pounds, and many (though not most) will understand.

You're even allowed to be a pedant, as I am often accused! :)

Last week I stood outside my apartment and watched Tiangong fly across the sky[0]. What an incredible time to be alive. [0] https://james.darpinian.com/satellites/

Tiangoon flybys can reaches magnitude -2 now. Bright than most planets. Next bright evening flybys overUS in early December. The ISS, which has five times more modules, reaches magnitude -4 sometimes. Third brightest thing in sky.

For clarity, #1 is the Sun and #2 is the Moon. ISS is brighter than literally everything else in space, including all the other stars and planets.

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'…

It's not just that the key isn't populated; it's that it's undefined. FWIW, my browser (Chrome) works on the site even if I choose not to share geolocation; I assume because the API is populated even if it then refrains from sharing. Your point isn't quite wrong but it also isn't quite right; geolocation is supported by every browser listed on Mozilla's documentation ( https://developer.mozilla.org/en-US/docs/Web/API…

None of the browsers on my iPhone will render this site, W3C compliant or not. In any event, I would never tell my users that it's their fault that my app didn't check the truthiness of the object's property. Seems particularly hostile to one's users and customers, free product or not.

Now let's hope it will inspire more countries, or even companies, to launch their own!

I'd prefer countries to cooperate more. There's no need to have dozens of national space stations or even launch systems. Some diversity is Ok, but it's just too damn expensive.

I think that was the hope for ISS in general with the rationale being that the cost would be just too expensive for any one country to bear. And ISS, not completely unlike the globalization and connections between countries would force some modicum of cooperation.

I think we were way too optimistic about ourselves as a species. Our cooperation does not last long.

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.

"Licensing" is a strong word when applied to China. I'm pretty sure they have advanced a lot and may have surpassed Russian technology in some areas. As far as I understand it, they have more diverse launch vehicles, for example. Hard to compare what constitutes "better", as long as it works. I don't think they are as cost-efficient as SpaceX or even Atlas and Ariane systems.

> I don't think they are as cost-efficient as SpaceX or even Atlas and Ariane systems.

It seems unlikely anyone is as cost-efficient as Falcon 9 with reuse.

It appears to me, as an outsider, that Atlas and Ariane are 4-5 times as expensive to operate. There is probably plenty of room for China to operate more efficiently than that. Especially with their launch volume, which is second only to SpaceX.

Your browser needs to support sharing geolocation.

No, it does not. An uncaught error where you don't catch and gracefully handle errors in your promises is not the users' fault. It's sloppy workmanship.

If you get this error, you intentionally broke your browser, or are using a browser which doesn't support standard, essential functionality. This is not the same thing as declining or blocking geolocation permission, which is supported and does not cause errors.

This specific error means you deleted the standard functions that implement the geolocation API, which is a completely different thing. That's fine too, you're welcome to browse the web with a broken configuration, but you have to realize that it will break things. You're not automatically entitled to request that every site support your broken configuration. It should also be noted that browsing with a non-default configuration like this makes you an easy target for fingerprinting.

Note that the site absolutely requires some form of geolocation to work at all. Satellite viewing times are location specific and without a precise location the site can't show you anything useful.

That's a monopoly problem, no? Apple doesn't actually let you use different browsers. You should try it on an android phone?

Each launch costs hundreds of millions of dollars. The cost of bringing the rocket down in a targeted way can be substantial, in terms of R&D, fuel, and mission constraints. And the risk is absolutely minuscule: Exactly one person has ever been hit by orbital rocket debris after tens of thousands of launches over more than half a century, and it was a tiny piece (which is usually all that survives re-entry) that didn't cause injury:

And of course, the launching nation is responsible for compensating anyone injured or who has property damaged by space debris, and paying for clean-up.
