Fair point. Let's see if any space agency will try sending them somewhere, the data received on how they will react on different planets will answer many questionsChris Peterson wrote: ↑Tue May 23, 2023 12:50 pmSure, they might hibernate for a few weeks or months. But that's about it. Heck, they aren't even considered extremophile life forms!Rauf wrote: ↑Tue May 23, 2023 8:01 amThey won't possibly thrive on a planet with no food and no accessible water. But what if, they go in a state of hibernation, or parts of their body like DNA or certain proteins stays intact, on the long run, maybe some part of their body on some form on the planet. I'm just thinking that it might be too early for us to just send them on another planet, at least without direct human supervision. From what I've read about Tardigrades, they will wake up even after 40 years of total dryness, while if they have water nearby, the won't live no more than a couple months. I think that if we are to send them on other planets, it should be with extreme care.Chris Peterson wrote: ↑Mon May 22, 2023 4:20 pm
Mars is an incredibly hostile environment. Again, I can think of no lifeform that could survive there, at least no anywhere near the surface (which is where contamination would occur). Life on Earth is highly interconnected. It exists within a system. There is no organism on Earth that can survive without interacting with other species. What do you imagine a tardigrade on Mars would eat?
