It was interesting, to track where things were sticky for them. And NASA's brand really played large there, in ways that were beyond what, I think, I had seen. Both in terms of the draw, when presenters from NASA were talking about their work, and missions, and stuff like that. And as Bart pointed out in the recordings, this table that had the NASA Meatball stickers, and how that was the prized thing. It was amazing. And there's something more to it, it was taking the fantasy, and the reality, and blending that stuff together. And that, seemed to be fairly seamless, in terms of how people think about that. And so, there's something going on there, that's way deeper than anything that we actually have explored, or been able to explore.
