Can you tell us more about what they'll be testing for, what they're hoping to learn?

Why two hours?

I'm sorry.

So what they'll be testing for, looking at the astronauts' health, they'll be looking at all of those things that Jim Bajan was talking about, which is how the cardiovascular system is adapting, coming back on Earth.

They'll probably take blood samples and things like that later on to look at things like how your immune system's working.

So there's a lot of things that happen to the body that we really want to categorize

categorize.

If you're talking about why we go up into space, what do we look at when we get there, whether it's using the moon as a base to look back at the Earth or even understanding the geology and the history of the moon, it helps us to understand about our planet and how we might evolve.

So you can actually use space as a platform.

When we look back at the Earth, we can look at the agricultural systems, we can look at rivers, we can map.

We can even do things with sort of telling the spread of diseases by some of the geographical features.

There's so many things that you can do from space as a platform.

And so if that's what you're talking about, the science, those are that pieces that are just from that perspective.

And then you can go even deeper looking at energy systems, looking at understanding how...

We're always people, we always talk about our cell phones and our GPS systems that we use really easily.

We ask Siri, Bertha, whoever to tell us how to get to a place.

We're holding a space receiver in our hand.

It's really permeated all of our society right now.

It's completely fascinating.

That was exactly what I was asking, and that was so interesting to hear about.
