> 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…

You mean compared to the US to use the largest spy organisation in the world to spy on contracts, technology, business secrets, and personal information of business leaders of other nations to get an edge.

It always buffles me how Americans can complain about things that China does (in the business world) while being perfectly fine about what their own government does in the same space. Many actually actively promote it.

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?

If you ever read the slightest about aerodynamics you wouldn't make such blatantly wrong, ignorant, arrogant claims that the J-20 and F-22 are 'identical'. They are of the most fundamentally different layouts in designing a jet. Do everyone a favor and shut up.

One of the best books about soviet rocketry is "Rockets and People" ([1]). My blood boiled at how badly German engineers were treated on the Soviet side and how inefficient the use of their skills was. They literally landed Germans on an island and gave an important, but a standalone task (multi-channel telemetry). Over time, it became redundant and 7 years later all surviving german engineers were let to go home. It…

It's even more impressive that the USSR did all that without using German scientists.

To be more precise, without using German scientists to the full capacity.

This multi-channel telemetry was enabler; Soviets followed the same approach as SpaceX is doing: lot of launches, lots of explosions and learning something every time.

It was telemetry from the German team that allowed this approach to happen.

In a sense, printf-style debugging was used before it became prevalent in computers.

Now that more and more countries are getting into space exploration, I wonder how long it will be before commercial companies start developing and selling space probe platforms (just like launch platforms now).

Rocketlab is heading down that track already with their Photon satellite platform: https://www.youtube.com/watch?v=LAUj-TQpn-A

>"It's one sin to steal" Every successful country at some point stole / conquered / forcefully took from others to achieve prosperity. Look at UK for example. They've raped half of the world. Then they were crying a river when the US stole from them. Now they are telling other countries not to do what they have done. Those other countries might listen when they will have "stolen" enough to be well on their own.

Also Germany, the "made in..." Label was invented in the UK to distinguish their products from the cheap German knock-offs. Later "made in Germany" became a sign of quality.

Look all the copy comments aside, the future of the human race is getting off this rock we live on. Congratulations on the success of this mission. It moves all of humanity forward.

Yes!! Moreover, China has optimized the process of massively scale production of everything. This is good as it decreases prices.

Seeing it as a global humanity achievement... this is great.

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?

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

Sure, let's make a list:

* Russia built a rocket that almost put its enormous core stage in orbit -- Energia -- but were careful that it didn't. 2 launches total.

* The Space Shuttle was careful to not put its enormous external tank into orbit. 100+ launches.

It's one thing to lose control of a space station before it re-enters, numerous countries have had that happen. It's another to design a launch system that's intended to have a large thing re-enter uncontrolled. Russia? Never. US? Never.

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 liter…

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

Except they are in English. I’m sure there are heaps of positive forums in Chinese on this topic.
