RE: How would the low gravity of MARS affect the colonists' bodies and genomes and how can we fight it - Colonization of MARS Series
To be honest, I am unsure that we can survive if we go to far from Earth. Even though science went quite far technological speaking, do we really know all the possible effects on the human body, of actually leaving the planet?
I am not a space geek, so I might be just ignorant. Still, the question is here for anyone more knowledgeable 😃.
If a medium size meteorite is hitting our planet, there will be huge fires and smoke can block the light for several years. Life in such conditions might be more difficult than the one on Mars. If we are a specie living on a single planet, we might also be extincted, like the dinosaurs. Being a multi-planetary specie, will enable us to return on a post-disaster Earth and resume our civilization. This is why we must go on Mars!
Thanks for stopping by. Your argument is the main one for space colonization in general, a version of panspermia, this time made knowingly by us.
That's a good question you are asking. But if some people want to test it out, so let them go. We can learn from them when they will have made experiences.
But i personally would like to stay on earth even if it's proven that we can survive on other planets.
Indeed, the goal of my series was to bring those studies to the public. Studies that get close to explaining all we know about the subject. As the studies progress we can say for sure that we will be able to survive for 1-2-3 years. It's what happens beyond that we have no idea of. We don't know if people can give birth in space or if fetal development is natural. We have made a few experiments with animals on ISS but nothing will prepare us. When the first men went to Space there were plenty of scientists sure that the astronaut would surely die.
We will just have to make baby steps and find out what is going on.
