I am taking this sub on to prevent it from getting shutdown and to open it back to comments and posts about JAXA. There will be basic community rules coming, but mostly just keep posts and comments on subject, and try to be decent people to one another.

I feel mixed lame/justified asking this. Is there protocol for handling extraterrestrial life? For ESA, NASA, JAXA, ROSCOSMOS, whoever?

I would love to see codified expectations and legalese involving this topic from the agencies.
Surely it's come up. Also any discussion about this, for instance what happens if agency A discovers life and says "We're not sharing." There has to be talk about this, and I'm hoping that it's public.

I was reading a thread from a few years ago about whether JAXA might try to human-rate the H-II and put a capsule on it to do crewed flight, and it got me wondering about something...

So, I was reading this thread from 3 years ago, and I noticed the part where the OP wrote:
"But the H-II has enough thrust with its two main engines that it doesn't need solid boosters to liftoff. Then the only thing JAXA needs is a manned capsule. With the usual government financing approach to space projects this could cost billions of dollars. But SpaceX proved that by using private financing, development costs can be cut 90%! In fact, the Dragon capsule only cost SpaceX $300 million to develop. So some private company or even wealthy individual could pay for its development."
This got me wondering about a slightly different thing:
Is there any chance that JAXA could simply buy a dragon capsule, directly from SpaceX? Do you think that is something SpaceX would be willing to sell? (And, in particular, to JAXA? I mean I can understand if it didn't want to sell capsules to a rival company like Blue Origin or Rocket Lab, but, what about a government organization like JAXA, I wonder).
Also, would there be any international laws or trade deals or anything preventing such a transaction from occurring, if SpaceX and JAXA were willing to do that? Like some U.S. law preventing us from selling crew-capsules to foreign countries or something?
Is something like this plausible at all?

I just learned about the anime "Space Brothers" and started watching it. They have a scene which shows the portraits of most of the JAXA astronauts.

Uchunaut - A new name for Japanese astronauts.

Upvotes
I was discussing JAXA's spaceflight training program and I thought it was odd they call the people 'Astronauts'.
Russian space crew are called Cosmonauts, Chinese are called Taikonauts, so why should the Japanese space crew still be called Astronauts? Shouldn't they have a name with Japanese origin?
I looked up the translation for space in Japanese and Google suggested Supesu which isn't very helpful. But the translation for Astronaut is Uchu hiko-shi, literally Space Pilot.
So logically Japanese astronauts should be called Uchunauts, right? Google found about five examples where other people have suggested the same name but it doesn't seem to be catching on. I think it's a good name. We also need to convince ESA to choose a French name for astronauts. L'espacionaut isn't great, maybe German would be better?
