I mean I love tardigrades! One thing I love about them is how accessible they are, they're a super unique and cool micro organism that can be found by just scraping some moss off a tree, sprinkling some water on it, and looking at it under a microscope. i think it's great when science can be that accessible. also they're super cute! A fun fact is that instead of their name being a combination of two latin words: tardi (slow) and gradus (step), there actually exists a word in classical latin, tardigradus meaning slow stepping after which they are named. I think they're amazing as extremophiles but i also take comfort in the fact that they survive in suspended animation in their dehydrated tun state rather than truly being alive in these extreme conditions. when you send a tardigrade to space, you aren't sending it alive, you're sending it in suspended animation and I find that comforting.
