Comment:

Had this mix for a while. Wanted to be an astronaut when I was a kid. This is the closest I could get.
To avoid duplicating, I cross-checked this theme with ones by KathrynandRupert, blasikin, and musicgnome. The 'gnome-ster is most prolific in this vein and far more in-depth than my list.
