Some history on NASA astronauts wearing their (military) wings.
☕
I always liked how the US military branches almost immediately had their version of an Astronaut wing ready. Alan Shepard and VIrgil Grissom received their aviator/pilot astronaut wings in December 1961 with Glenn following in March 1962 getting his US Marine Corps astronaut wing.
We all know that pilot/aviator wings have always been worn on the heart (leftside) but NASA wanted to emphasize a "civilian" look during the Gemini Project by putting the NASA meatball on the heart.
Funny, while the Gemini astronauts were asked to perform military tasks (e.g. Gemini V observed a “Minuteman” launch and Gemini VII photographed a “Polaris” launch).
In fact the Gemini astronauts wore the black leather name tags, not their wings but on Gemini VIa Schirra and Stafford effectively wore their "metal" aviator/pilot wings on the actual space suit, the first to do so (later on Gemini XI both Conrad & Gordon wore their sewed-on US Navy aviator wings on the space suit).
By the time of Skylab, the name tag moved to the leftside again. BY the time of STS, astronauts started to wear their wings again on the leftside of the pumpkin suit.
NASA came up with a mission/payload specialist astronaut wings and I believe the US Coast Guard were the most recent with their USCG astronaut wings as we already have 3 USCG astronauts; Bruce Melnick, Daniel Burbank and Andre Douglas.
