Tbf we don’t really need our organic eyes, we’re pretty close to just being able to make cameras we can shove in your eye sockets lol
The people willing to go to Mars literally don’t care. There could be a 75% chance of death and you would still get a ton of extremely talented people willing to go, especially to be among the first. They don’t care about radiation, long term health problems etc.
500 years ago going to the new world was considered suicide and had an extremely high chance of death (usually painful) and people still sent it while having entire families at home.
Before that, Polynesian sailors, Viking sailors, and many other civilizations. Men going out on big ships with minimal/zero intention to make it back home has been a thing since forever.
You can never take the inner urge of exploration out of a Man.
Reading some of the comments. The lack of connection with reality of some Mars Colonization Fans is fascinating.
Radiation? Put water supply around living quarter to double as shielding.
Microgravity? Use spin gravity. If we cannot make individual ship of large enough size, then use Aldrin cycler.
Simple as. Just mail the Nobel prize straight to my house, thank you.
Okay but astronauts can still see when they come back to Earth. If it took this long to discover, then the issue is probably not that big. There’s even been a cosmonaut that’s spent 2.5 times longer in space than people would on a Mars mission and he’s fine.
>According to the researchers, these ocular changes **are generally not cause for concern** when the space mission lasts six to 12 months. Although 80% of the astronauts they studied developed at least one symptom, their eyes returned to normal once back on Earth.
“Raising concerns,” come on…
There are many studies that show the many ways in which the human body will break down in space travel.
Personally, I think the race to Mars is just on it’s face stupid, and amounts to nothing more than a egotistical fascination with planting a flag on some place first.
We need to be sending more probes into deep space, we need to be focused on discovering the physics of the world. If we find ways to become space travellers, it won’t be from aiming for Mars, it will from foundational scientific discovery that bends our understanding of space time, energy, matter, gravity (etc.).
Unfortunately, Trump seems to really really hate scientists and thus far has issued a lot of executive orders to halt basic science funding.
Bruh if I get on a spaceship to go to Mars, I’m fully accepting I might be the first of what would ultimately not even be considered human down the line after we’ve been on Mars for a while.
This is like the least of the concerns when talking about travel to Mars. Imo, it’s incredibly unlikely we will be doing this trip in our lifetimes, and that’s entirely because of biology.
The human body can’t handle Mar’s low gravity either.
Mars is not going to happen for decades if ever. Chemical rockets are simply too slow. Heck, we can’t even do a sample return.
