Reading about the North Korean space program, and its recent launch of the Kwangmyŏngsŏng-4 satellite, I stumbled upon this logo:
I am, however, a little in doubt about this one. The main reason is the acronym "NADA" (National Aerospace Development Administration). That really does sound like a pun, meaning "nothing" in Spanish, and the word is used about the same concept in several other languages. Also, the agency is much more often referred to as "Korean Committee of Space Technology" (KCST), so why the sudden change of name? However, some sites, like North Korea Tech uses that name, and the wiki page exists.
Honestly, I can not tell if this is a joke or not, as you never know when talking about North Korea.
