Interesting news. If you haven’t been tracking, the Israeli “Beresheet” landed on the Moon rather abruptly in April. Well, or in other words, crashed. So, aboard it were tardigrades encapsulated in artificial amber – spineless creatures considered nearly indestructible. They withstand freezing to absolute zero, strong radiation, and heating up to 150°C. They have already ventured into open space – and survived. In the absence of water, they literally dry out and enter a state of apparent death, but it’s reversible as soon as water reenters their system. Due to no water in their cells, they aren’t ruptured by deep freezing or boiling. The spacecraft crashed, but these little friends are scattered somewhere. Theoretically, they could be revived in the future, and in the artificial amber at those temperatures, they might well wait an eternity.
Also, I recently read an interesting fact that life on Earth is impossible to annihilate. First, these tardigrades from the previous paragraph. More specifically, in the last ones. Firstly – the bacteria in the depths of the earth. It turns out that their total weight amounts to “…17-25 billion tons, which is 300-400 times more than the mass of all the people on Earth”. Thus, these little friends are impervious to destruction. Unless, of course, an asteroid hits the Earth and shatters it into small pieces. Even then, life would still remain, albeit in a somewhat conserved form.
