Tough as a Tardigrade Phone Case

Of all the creatures that ever lived on planet Earth, Tardigrades are perhaps the toughest. These little indestructible water bears can survive all the extremes that we can throw at them. They survive in extreme hot temperatures, extreme cold, even lethal radiations. They can even survive in Space! It is believed that these little units are probably already living on the moon after hitching a ride with some of our rovers.
