It seems pretty silly to get all up in arms about copying other peoples' stuff. That's how humanity has innovated throughout the ages: Copy what works and innovate on top of it. None of our inventions arise from a vacuum. Cars are still as wide as Roman chariots for good reason. Power transfer uses the same base principles as were in play during the dawn of steam engines and before. Energy conversion has been an iter…

Is there any evidence that there's copying going on? I tried searching online, but couldn't find any. A few months ago I saw people claiming that the leading choice in the contest to name the rover was "Perseverance"[1], which wasn't actually true (see the comment about how 弘毅 is translated). There seems to be a lot of misinformation out there these days.

This raises a questions -

as China's Yutu-2 moon rover is still operational on the far side of the moon, if Rongzhu mars rover could be successfully deployed, assuming those two rovers (Yutu-2 on the moon and Rongzhu on the mars) can communicate with each other, via some relies of course, will that make it the first communication between two planets outside earth? has that been done before?

Earlier quoted context omitted.

When the Voyager missions were launched most of the world didn't have international calling. So making a call from lets say Somalia to the US, involved finding a post office with the only international line in town and "booking" a call. Which meant you had to walk over and write down your name (and if you were lucky enough to have a local landline your 4 digit phone number) in a ledger and then walk back home to sit…

When the voyager was launched, telegram was the dominant mode of long distance communication in my country.

Which country is that?

The Americans got the scientists, the Russians got the technicians. They served as catalysts for both space programs, but there was also a lot of talent from else where (America is famous for deporting a Chinese rocket scientist in the 50s or 60s, giving a good start to their program).

I'm a Chinese guy and I don't like this at all. Here's some Chinese perspective: 1. The CNSA is severely underfunded in recent years, to the extent that a considerable amount of space tech graduates went directly into other more "lucrative" fields such as the IT industry. 2. This landing operation was not announced beforehand. This is a bit unusual, when compared to the past operations, e. g. the first manned space f…

To be fair, NASA has the same problem. Rocket science just doesn’t pay as well as a FAANG programming job, even if you are trained up for the former. At lot of fields that traditionally attracted smart people are suffering similar issues.

Except for the fact that there is no solid proof of "concentration camps" and genocide...

Meanwhile, certain countries are totally okay to support despite the documented million plus Muslims they have killed over past decades. Ironically these are the same countries that are throwing around accusations of genocide.

in my opinion africa should ditch everything and focus on copyright business. since this all started there, they would be the richest continent in no time.

I was just telling my wife about this yesterday and how Wernher von Braun basically saved the US rocket program; or, at least, it was having major difficulties before, and major successes after he joined up. And, in addition, the Germans in the 1930s got a lot of good information from Robert H. Goddard, the inventor who built the first liquid-fueled rocket; Werner von Braun said, about him, "His rockets ... may have…

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 c…

Wait the UAE is sending a probe to mars? I haven't heard anything about this. Is it going to be a rover, or just a satellite?
