You're absolutely right.

You know, using kind of resistance because you can't use – you know, weightlifting doesn't make sense in a weightless environment.

And all of that is really meant to minimize the deconditioning that happens to the body, right?

But it doesn't eliminate it.

If you didn't do that kind of exercise – and they exercise about two hours a day every day.

So, this is not like a small amount –

If you didn't do that, you'd be in way worse shape.

So, you know, we've arrived at Mars.

We've done our two hours a day every day.

Still, it's going to be a challenge to just get up and move around.

Who knows what the cognitive effects of that radiation exposure?

You've been exposed to galactic cosmic rays for six months.

Nobody's ever had that happen.

We simply don't know what the effect will be.

And then there's another factor.

What have you been eating all this time?

You know, astronauts, you know, we're all kind of familiar with the idea of like freeze-dried foods and stuff like that that astronauts typically bring with them.

They are having to bring kind of, you know, shelf-stable food.

But even in the International Space Station, they're able to occasionally resupply them with some kind of fresh food, some fresh produce, etc.

There's a story of Russian cosmonauts, the first to be living for a longer period of time on a space station.
