I don’t think this has been true for the vast majority of NASA’s existence. [This 1966 NYT article about Gemini](https://www.nytimes.com/1966/03/20/archives/gemini-8-mishap-...), [this 1986 article about Challenger](https://www.nytimes.com/1986/09/22/us/nasa-had-solution-to-k...), and [this 2010 article about Constellation](https://www.nytimes.com/2010/05/27/science/space/27nasa.html) all omit periods. Even if NYT did stylize it as “N.A.S.A.” in its earliest articles, this would not diverge from common agency practice early on. For instance, in [this official reel about the dedication of Marshall Space Flight Center](https://www.youtube.com/watch?v=4fasslw4MvE), it is pronounced spelled-out as four letters.
