Just How Tough Is Earth Life? Tough Enough To Go Space And Still Thrive
Every time we send a spacecraft to another world, our Earth-based lifeforms are going with us. No matter how well we try to keep them clean, a few stowaways will always come along for the ride.
You’d think that years in the cold hard vacuum of space, suffering extreme temperature changes, and receiving brutal doses of radiation would be all it takes to sterilize any life caught on the outside of a lander or rover headed to Mars or Europa.
Well, think again. Life just demonstrated that it’s surprisingly ready to make the journey, and happy to get back to work the moment conditions improve.

Yeah... What about global warming?
These kinds of lifeforms should be able to handle global warming. As they Earth heats up over billions of years, they'll be the last ones to die.
If other lifeforms can survive in space why not humans?!
Because we require a better environment. Air pressure, temperature, etc. We're fragile.
Excellent-- I'll look forward to the sequel
Thanks, it's written and we're working on it now.
Thanks for all your work! I used to search small bookshops for interesting books about astronomy (beyond the "popular" kind) , and found very little. So you can imagine my joy finding channels like yours, especially the more technically and obscure papers you dig up. Thanks! I do have a question. If it is possible to create artificial gravity by connecting two part of a spaceship together and a lack of said gravity is so detrimental to the human body, why is it not implemented, especially for a trip to mars. Thanks in advance!
Thanks a lot, I'm glad you're enjoying them. I've done a few videos on the quest for artificial gravity, and there are actually some really cool proposals that could make it happen. https://www.youtube.com/watch?v=SHfUbNRO-3A&list=PLbJ42wpShvml6Eg22WjWAR-6QUufHFh2v&index=41&t=1s
