Yeah, yeah, well, I think it's Justifying Space, and then the subtitle is, you know, A History of Space Futures.

Okay.

But it's a fun lens to look at the history and the present of space exploration, because it's not quite just asking, what happened?

It's what were people thinking?

What was the motivating vision?

What future did they think they were creating?

So, you know, you can go all the way back to H.G.

Wells and Jules Verne and those kinds of images and then up to, you know, Wernher von Braun and, you know, Robert Goddard and, you know, sort of start of rocketry and Apollo and, you know, all these, like,

inspiring visionaries like Carl Sagan, you know, what kind of future were they helping people imagine was going to come to pass through space exploration.

And then you can take it right up to the present.

And Carl Sagan, who you knew very well.

Yeah, big influence.

Right, right.

Oh man, I grew up with, he and my dad were best friends, actually.

Sagan and my dad, they were both Harvard professors.

Oh my God, get out.

And before Sagan went to Cornell, because he was denied tenure at Harvard.

Take that, Harvard.

Yeah, so he was kind of in the household when I was six years old.

He was Uncle Carl and kind of just around as I was growing up, which was pretty interesting in a lot of levels.
