It's impressive how far China has come in just 2 decades. How significant is this achievement space technology wise? I still remember the first rover on Mars and it was a really big deal in my eyes back then.

With the stolen research from many countries.

At this point, I don't care what they steal, with the exception of military related research.

(And no--I have no citation. I have just read about to many Chinese citizens being arrested on American soil for espionage, and theft of trade secrets. Remember the guy collecting genetically modified seeds in the midwest? I could care less about Monsanto though. I do care about NASA secrets.)

They steal research from "the many countries" that haven't been to Mars? That seems quite an odd accusation. You just handwave the need for evidence away as if such an accusation can be assumed to be true. Arresting people on charge of espionage doesn't mean that those people actually engaged in espionage: proper due process must be finished first before that conclusion can be drawn. Also, stealing trade secrets in certain areas has got nothing to do with stealing secrets in space technology, so it's whataboutism at best.

How exactly are they supposed to steal research when they've been banned from space collaboration programs? Assuming that even if they did manage to steal some research, how can that strategy possibly be more successful than countries that haven't been banned from collaboration? That makes absolutely no sense.

No, China developed their space technology on their own, with their own research, by their own hard work. This is the result of accusing them of stealing and banning them: they go their own way, successfully.

Consider that China is banned from the ISS and other kinds of space technology collaboration programs. China had to develop all space technology on their own. Some perspective on how significant.

They also steal research, but, I understand the point you are trying to make.

I think some evidence is needed for the accusation that they stole significant space technology research.

I had no idea they had a rover on the way, very cool! What is the objective and the interest in the Utopia site?

It had some coverage here, it was one of the three probes headed for Mars this year, other two being the US and UAE probes.

The rover itself is not as larges as the Perseverance or Curiosity, but their orbiter seems a quite heavy probe. Hope we will get some detailed high-resolution images of the surface from the orbiter, so that we can have even better surface maps of Mars.

Also the CNSA programs don't get as much coverage in the West. Their Chang'e 5 lunar sample return probe was quite a good achievement, with they being able to do an autonomous docking in lunar orbit.

All things considered, 90 days is pretty good for how harsh of an environment Mars can be. Also, there are dozens of ways to make the mission last longer but no ways of accomplishing that without adding more weight.

This makes me think about the way we define “harsh”. What’s actually so harsh about Mars? Let’s imagine some alien civilization tries to send a probe to Earth, they’d be saying things like: “Dude, that atmosphere is gonna burn our shit up before it even touches ground, if we’re not careful.” “Holy shit, what are these huge animals with long noses and big ears? They’re gonna destroy our probe if they walk over it.” “L…

Most of the dust is extremely sharp, not having water break up the edges.

Does anyone have plans to land on Venus? Is that way more difficult or something?

NASA has been soliciting lander designs[1], as well as coming up with their own[2].

When you look at the history of space travel. One of the first space programs (NASA) originated from Germany developments. North Korea nuclear weapons from Soviet undercover collaboration. Not familiar with specifics for your claim above, but just stealing is a miniscule part of what is really required for this type of effort

Space research in the US started before the Germans joined, but it never worked... The US had to bring Germans to make the whole thing successful.

I think you mean, German Jews brought their innovations to the US because Germany tried to kill them.
