Bottom of the article in OP https://boundingintocomics.com/files/2020/01/2020.01.25-02.11-boundingintocomics-5e2ba3e7561b6.png >>According to a spokesmen for Space Force as reported by Valerie Insinna, “The delta symbol, the central design element in the seal, was first used as early as 1942 by the U.S. Army Air Forces; and was used in early Air Force space organization emblems dating back to 1961.” That’s a full five years before the September premiere of Star Trek: The Original Series. ... It is very clear that the logo for Starfleet was inspired by the logo from NASA. Even Star Trek’s official website notes that the delta emblem used in the Starfleet logo is a direct descendant of the old NASA logo. It reads, “In the Star Trek universe, the delta emblem is a direct descendant of the vector component of the old NASA (and later UESPA) logos in use during Earth’s space programs of the 20th and 21st Centuries.”
