Tardigrades live an extremely long time, and right now scientists are studying them in part because they have proteins in their body that might stop or slow aging. They are unbelievably tough, they live on frozen mountaintops, or deep in lava tubes at the crushing bottom of the sea, and can be found almost everywhere on Earth. When life gets to dangerous they can go into suspended animation and wait until they are in water at a safe temperature and cleanliness to wake back up.
We have even sent tardigrades into space to see just what they can survive. Including exposure to life outside a spaceship! They are THAT tough! We are hoping that will lead to knowledge to help us travel into deep space ourselves. (Here’s a great article that came out after I recorded this episode!)
