Emblems of Exploration — Logos of the NACA and NASA
TL;DR — NASA’s 164-page history of its own logos, from the NACA wings to the meatball, the worm and back.
NASA SP-2015-4556, Monographs in Aerospace History no. 56, from the NASA History Program Office. It traces the emblems of NASA and its predecessor the NACA: where each design came from, who drew it, and why the agency switched.
What it is: an official agency history. It sits next to the brand-guideline PDFs already in the library.
