I'm sure the other astronauts are really looking forward to fly with a person showing signs of tolerating massive risks.

Each and every one of them is fully aware that it’s a massive risk and has made their peace with that. You’re getting strapped to a giant rocket. It’s inherently dangerous

Right, so let's add more risk by flying side by side with some nutjob with no regard for their own life. Sounds reasonable.

I don’t actually think astronauts take massive risks. They take massively well-understood and meticulously mitigated risks.

Maybe this is a perspective or semantics thing, but I think it’s distinct and important. They’re not Mavericks they’re Icemans.

Hopefully they're well-understood and meticulously mitigated risks. Because if they're not... well there's always modern day Boeing.

Historically, around 60% of all astronauts were from the military which is a high-risk occupation.

In the 50s, there was something like a handful of test pilots dying every single month. A subset of the ones who survived became the first astronauts. My understanding is that there are still a significant number of astronauts who were test pilots first.

If you don't have massive risk tolerance, you don't sign up for a moon mission.

If you would give your live for a single awsome trip (and you would still have multiple years to live), then you are likely suicidal.

Even if it is rational because your live sucks so hard, I would still have to classify you as suicidal.

Is jumping on a grenade to save another person suicidal? Or is it just a matter of you not agreeing with the rational?

No. You save another person. An awsome trip isn't the same.

Of course it isn't the same, but it does show it is just a matter of you not agreeing with the rational

...no? It's the same as when you say you'd 'die for somebody'. I don't want to die, but if I had to die to save my family I would. That's not being suicidal. Similarly, if space is important enough to you to take this risk (which realistically is a pretty low risk!) I wouldn't call that suicidal either. I take the risk of death driving in my car every day; that's the nature of life.
