I would still qualify “space” as a noun here, but that’s if you accept these kinds of constructions as sequences of nouns rather than the zero-conversion of nouns into and adjectives.
In Ukrainian those type of phrases would be converting the first noun into an adjective or into a prefix (either hyphenated or completely joined with the main noun)
In german, space billionaires would be a single, combined noun (Weltraummilliardäre) while space billionaires would be two separate words, a verb and a noun (Milliardäre verteilen) or, in the spirit of the meme, even more words (Milliardäre in den Weltraum aussetzen/dem Weltraum aussetzen).

In my head I read it translated as “Milliardäre spacen” ^^ Both of them. (:
