NASA scientists are intensifying their investigation into a vision disorder that affects 70% of astronauts on long-duration space missions, as new research reveals the condition poses mounting risks for future Mars exploration 1 2. Space- Associated Neuro-Ocular Syndrome (SANS) causes crew members to experience blurred reading vision, swollen optic discs, and flattened eyeballs that can persist for years after returning to Earth
It’s almost like we should stop destroying this perfect insanely unique and suitable planet we live on until we’ve reached a level of bioengineering that allows us to artificially adapt to the significant environmental challenges of interplanetary travel…
I feel like a lot of people are going to take that as some sort of anti-space program sentiment, which may or may not be your point.
But for those people, I think it’s worth considering that we don’t know what all of those environmental challenges are until we go to space and find out.
One way or another, earth will become uninhabitable, whether by our own hand thanks to climate change nuclear war, etc. or by some natural phenomenon that we are powerless to prevent- gamma ray burst, asteroid impact, the sun dying out
In all likelihood, we won’t have to worry about those natural disasters for hundreds, thousands, millions, or even billions of years, but we don’t actually know that for sure. For all we know, we could just be days away from destruction by some ridiculously powerful space-bullshit that we don’t even know to be worried about yet.
We aren’t always going about space exploration in the right ways or for the right reasons, but every tiny step we take does inch us closer to a better understanding of what’s all out there in the universe, what dangers it presents to us, and how we can avoid or counteract those dangers.
If we hadn’t been sending astronauts into space for the better part of the last century, we wouldn’t know that it might cause these kinds of vision problems, and so we wouldn’t know to work on a solution for that to have it ready for when it’s really needed. Sure would suck to have all of our other ducks in a row to set up a sustaining Mars colony or whatever, only to find out when we got there that 70% of our colonists can’t see right due to the trip there. Now we know, and we can work on a solution, whether it’s bioengineering, or special contact lenses, or whatever may be needed.
