So

Vero G floating around, hypergravity, like high G forces on launch and reentry, or sort of low gravity on the moon or Mars.

And there's a lot we don't know about that right now.

And E is extreme environments, like extreme temperatures.

Or moon dust is basically like tiny bits of glass shards, if you think.

You know, we have hazards with things on Earth, like silicon, asbestos, moon dust will be like that too.

And we have to figure out how to handle it.

Yeah, it depends what vehicle you're on.

So if you're on the space station, you're under the Van Allen belts, which protect us from a lot of the radiation on Earth.

So you get more up there, certainly, but it's not as bad.

And different space agencies have a lifetime limit on astronauts, after which they shouldn't fly anymore.

So NASA's is one sea vert for any radiation experts that are listening in.

When you get above the Van Allen belts, so when you go out to the moon, for example,

you're subject to a lot worse radiation.

So our sun has a solar cycle when it basically, when it shoots out more radiation and that radiation can be like rays, it could be particles.

But when it's more active, it protects us from the worst stuff.

The worst stuff is from like our galaxy and intergalactic radiation called galactic cosmic rays.

So you have a time where when the sun produces less radiation,

you're more exposed to the really bad stuff.

So it's a bit of a trade-off.
