All: if you can't post anything but cheap nationalistic comments, or other obvious reactions, please refrain from posting. The goal here is to have interesting conversation, which is the opposite of reflexive generic stuff [1, 2].

If you're not sure whether you're facilitating interesting conversation, here's the key: what's interesting are the diffs [3]: the specific, interesting details that haven't been repeated before or elsewhere. Ask yourself whether your comment could appear in any thread on some generally related theme (e.g. space, China). If yes, it's probably not interesting in the sense we're shooting for here. The goal is to consider things we haven't before.

Please note: this isn't about being 'positive' vs. 'negative' - it's about not being repetitive/predictable. That's different.

Ah yes, so the chinese were "given" the designs to other military aircrafts which is why their fighter jets look identical to those from the USA and Russia? [0] https://www.popularmechanics.com/military/aviation/g23303922...

...those don't look identical. It lists the J-20 as a knock off of the F-22, and you can even tell from the picture they use that they're radically different airframes.

Please explain the differences that you see because the philosophy looks pretty damn identical. Aside from the obvious addition of forward canards on the J-20, the two aircraft look nearly identical thanks to China’s access to classified F-22 development data. They were caught stealing from Lockheed Martin data on the F-22 program with a successful conviction in 2016

You are blatantly lying that a hexagon looks identical to a rectangle. Shameful.

Ah yes, all of the design similarities are just cosmetic, right? They certainly haven’t had their spies convicted of stealing American aviation technology ever?

Ah yes, voluntary theft. That's a thing that we can justify now, huh?

You need to go back to school and re-take a course on logic.

Was technology given or was it stolen? Just because companies are aware the theft is going to happen doesn’t mean it’s morally or ethically something that you can defend. Theft is theft.

"Hey NASA, can I copy your homework"? "uhhh..." "It's okay, I'll just change it up a little bit so it doesn't look like a 1:1 copy of Spirit and Opportunity" https://www.dw.com/en/chinas-tianwen-1-enters-mars-orbit/a-5... More seriously, there's probably only so many valid 6-wheeled rocker bogey suspension type rover designs that are possible, but the resemblance is uncanny. NASA also likely spent a lot of time study…

Please don't lead with flamebait. You couldn't do anything more destructive to a thread like this. You're far from the only one doing it, but it's dismaying to see from such an established account. Please don't.

Um.. why isn't this being talked about more? I remember the discussions were very lively everywhere from Youtube to HN and Reddit when India was attempting to land its probe on the moon. A rover on Mars is a huge thing! Why are discussions relatively tame now?

It's the western media... They spent several hours talking about another rocket launched by SpaceX as if it was a big scientific advancement. But a major advancement by China is gonna be a little notice, or maybe they will say how this is a danger for everyone.

The wings have a completely different shape, the intakes are completely different, it doesn't have horizontal stabilizers, etc. I could go on.

> China had to develop all space technology on their own. It’s hard not to laugh at that statement. China runs the largest IP theft program in the world. To the point U.S. companies factor it in when doing business there. Just search this - https://duckduckgo.com/?q=china+steals&t=fpas&ia=web They also had the “thousand talents program”. That’s not to say what they did was not impressive, it was. But it’s also a lot…

We detached this subthread from https://news.ycombinator.com/item?id=27161834. What an utterly wretched flamewar. I'd scold all of you individually, but it would be too much work.

Please read the site guidelines and take them in more deeply. There's a lot there:

I went from earning $10K/yr as a student to a $120K income full time over the course of a month, why aren't you worshipping me and writing news articles about my accomplishment? Is it because rate of change doesn't count as much as you think it does?

i think the difference is that only 2 countries have successfully landed on Mars while the amount of people earning 120k is quite high

Four governmental organizations have landed on Mars. Can’t forget the Russians and Europeans did it first. But that’s besides the point because I provided a hyperbole where my rate of change was significant but not newsworthy. We aren’t celebrating them because they went from there the fastest but because they went there at all. How fast isn’t noteworthy because they’re standing on the shoulders of giants. They literally copied the design of our rover from 20 years ago and I wouldn’t be surprised if they had stolen a lot of those tech specs from nasa long ago

Western media are more interested on China's failure than her success. Example : Recent hyping of Long March uncontrolled reentry.

I believe even though western media are more free in principle there are only a handful of corporations which have the loudest voice.

So the comparison is between western corporate media vs. Chinese state media. That said, internet discussion forums like this are a good counter balance to corporate media
