It's a lot bigger in 3D when you can float around.

That's what I'm telling myself.

The other day we figured out where we might all hang our sleeping bags.

One person will be bat-like and hang in kind of from, to describe it, in the top part of what you can imagine the capsule shape is, there's a little bit of a little pop-up, a tunnel.

And so that will be where they hang either feet up or head up.

And then the other folks are kind of being more like what you might consider horizontal with what is the bigger base of the capsule or the floor kind of.

That's what I'm saying.

Our primary task is observing, observing the moon in the short period of time that we have our flyby.

Our job is to tell the scientists back home the things that lunar probes can't see or tell, and that is what colors do human eyes see?

What observations, large scale, do we see?

And it's a supreme responsibility to have eyes on the far side of the moon.

We hope that we'll be able to see it depending on its phase.

I like to allow space for that every once in a while.

And for me, allowing about two seconds every couple months is enough.

The enormity, when it hits me, is there and it's important.

But for the most part, I'm focusing on the mission.

When I look at humanity and the call to explore that humans have put out there, we were always going to go back to the moon and go back to stay.

And so our role is just really answering that call.

Mission specialist Christina Cook said that astronauts are the calmest on launch day.

It seems ironic, but you consider all of the preparation, the years of preparation that they put in for this mission.
