Hank explains why NASA and the European Space Agency are in love with tardigrades and how these extremophiles are helping us study the panspermia hypothesis.

Except they get killed in millions daily because they only have defenses that work on nuclear weapons. They can't even thrive in these conditions, just withstand it for a longer time than other animals
I think it would be highly that tardigrades can seed another planet with life because eventually they will have to eat, and if what they eat here on earth is moss than this is something they have co-evolved with and will not find elsewhere. What do you say?
Tardigrades aren't extremophiles. They can't survive in harsh environments. They can persist. There's a difference. If you can survive, you could live there all your life, get food, and be fine. If you can persist, you'll still die, it'll just take a long time. And a tardigrade will still die in space, it'll just take a long time.
Also, tardigrades are kinda stupid. Yeah, they can survive armaggedon. But they can't survive the most basic things that they'd actually have to deal with on Earth, like... a worm. They can survive exotic things that are impressive, but they can't survive simple things that would actually be useful. Like how a honey badger can survive a bunch of bumble bee stings.
So we've sent some into space..
What if some of them were just left to drift and that's how the massive one in ST: Discovery came to be..
I mean they actually mentioned Elon Musk in it so this could well be the explanation for the big guy
I wonder if the Tardigrades can survive gasses, i mean posinous gasses, it would be cool then they can go the gas gaints, also what if Panspermia Hypothsis has happened and they happened apon our planet on the same time the astrode wiped out the dinosaurs just makes you think some time
Waterbears are low-tier garbage. If you want a good survivalist class, I suggest the Rat, the Roach, or—if you're feeling really extreme—you could try out an Archaean.
Also, you even admit "there's no way that would be useful on earth!" Yes, you're right. They're resistant to everything BUT what would kill them. Yes, they can survive for a long time in space. But they WILL die. It just takes a long time.
They're killed by the millions just on accident from snails, slugs, crabs, etc. Not to mention their cannibalistic.
"While tardigrades can survive in extreme environments, they are *not considered extremophiles* because they are not adapted to live in these conditions."
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
