We also had a logistics module.

My third and fourth mission,

I brought up the Japanese laboratory and how to get that installed and outfitted.

And then on my fourth was the Alpha Magnetic Spectrometer.

And during all those missions, we were doing spacewalks.

Not me, because I was always the pilot or commander of the space shuttle, and they don't let us go outside for obvious reasons.

We've got other people that can do that.

Do you want to?

No, I would have loved to.

Yeah, it's kind of a bummer.

Were you, like, peering through the glass?

You know, so, you know, what I'm watching for is, like, what's the bad thing that's going to kill these people, you know, at any moment?

You know, so it's a very tense eight hours plus.

When you have people outside that you're...

You know, it's remarkable that we've made it this far and done all these spacewalks, I think, well in excess of 100 now.

And we haven't, you know, had somebody seriously injured or killed.

So you're really, really busy during these space missions.

And shuttle crew members aren't doing a ton of science.

It's the space station people that are, you know, that live up there for the case of my twin brother.

I mean, do you think I have a lot of time in space, 54 days?
