I know it's a custom logo so it isn't a font and many have suggested Bambi, but is there really not a closer one?
Bambi barely passes as even looking like it
Thanks ahead of time

"The meatball is a hand-lettered graphic created by one James Modarelli, agency employee, in 1958, in his spare time."

Here is a comparison of the letters in the NASA meatball logo with Priamos Heavy
Would take quite a bit of editing to make it match.
I have not checked Bambi, but it might take a somewhat similar amount of editing.

After seeing this and one comparing it to Bambi I would say Priamos Heavy looks a lot closer than Bambi though so thanks a lot, I think if I just edit the serifs and a few small parts to look a little closer it'll pass as it

A font called "Space Meatball" is based on James Modarelli's NASA logo design. It's the closet match I've found.
