When you're living on the International Space Station, what happens to something as basic as the water you drink? How much of it gets reused?

Hello, Yvon.

Thanks for hosting this.

You start with a very important question.

Water is life, as we all know, and water is heavy, about a kilo, a liter.

So it is a resource that we cannot afford to send to space for daily life.

And we cannot afford to waste it either.

Are there any things you learned to do differently on the space station that stayed with you when you come back to Earth?

Yeah.

Now the Moon is continuing its merry way, and they, they're falling back to Earth.

Right now, they're literally falling back to Earth.

They've been falling for four days, accelerating the whole way, and they'll peak maximum speed, as we said, as they hit the atmosphere, about 10 kilometers a second, and then they'll turn into a fireball as the, you know, the w- the, the atmosphere slows them down and kinda chips away at their protective heat shield.

We'll lose comm with them for about six minutes or so, and eventually at about, uh, at about, uh, maybe something like six kilometers altitude, they'll open their parachutes.

We can talk to them again.

That's when I think we'll all breathe a sigh of relief.

Mm-hmm.
