For me what has always been amazingly fascinating about all of these missions (even more so for the Voyager missions) is to be able to work with so much latency!

In today's world, where we are used to working with millisecond latencies across thousands of kilometers, just to be able to do something with latency of minutes to tens of hours, boggles my mind!

Amazing accomplishment of humankind!

It makes me concerned thinking about what kind of biological contamination this rover might have brought to Mars that may seriously hamper the search for signs of past native life.

JPL is very forthcoming about their cleanliness procedures, China not so much. And they don’t exactly have a great track record in this respect.

China Daily has a nice animation of the landing process.[1] So far, though, no live video. [1] http://global.chinadaily.com.cn/a/202105/15/WS609f18aaa31024...

Ah, someone copied our homework again :) I hope that more things on Mars are a net positive anyway, regardless the nation.

Your homework? Thank you for taking us to Mars.

Not that I know of, Venus is kinda crazy. 90 ATM pressure, -1 pH acid rain, about 700 K temperatures at night, it's pretty absurd. Unless you want to make a probe out of solid Tungsten, you're probably out of luck. And good luck getting that out of low earth orbit, that would be stupidly heavy.

What if you designed a probe like a medicine capsule, with an outer shell that's designed to melt, but a smaller rover inside that can survive the heat/acid/pressure?

Designing the rover that can survive the environment is the difficult part.

Being part of the "western" aerospace industry and collaborating with NASA, I do consider it our homework, yes.

Congratulations on the recent success of Perseverance! Best of luck with all of your future aerospace endeavors.

This is so cool, imagine it would meet Perseverance and the droids would engage in some battle friendly cooperation!

Q: Are the landing sites even remotely close to each other?

Q: Had any of sides incorporated this somehow unexpected counterpart into their master programs? Can they update the programs at all?

Edit: grammar

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.
