This is probably satire, but in case anyone was wondering how they did figure out the atmosphere (could possibly maybe) smell like pee:
The technique is called “spectroscopy” and, in a nutshell, different elements and compounds absorb light differently, creating an absorption spectrum. Spectrum, spectroscopy. NASA found that the atmosphere was composed of ammonia and water, the two main ingredients in our pee, with ammonia in particular creating the scent. I think it’s very cool that, based on the slight differences in light, we can tell what’s inside the atmosphere of a planet many (and I mean many) light years away! And one light year is very long indeed, so it’s a really big distance for us small humans!

tricky to kow but a couple ideas…
Astronaut Chuck “Chuckles” McGee flew there, landed and while taking a shit outside wondered why everything smalled like piss and reported back
or
they know the chemical composition based on the JWST and we know the chemical composition of piss, so one thing leads to another and here we are
