Is this Another Biomedical Hurdle for Space Travel?
NASA has discovered that more than six months’ exposure to outer space—either through living on the space station or travelling to other planets or moons—weaken astronauts’ immune systems.
The only solution is to discover a light-weight material that can withstand the radiations and temperature.
Genetically modifying human skin to tolerate the radiation. I wonder if that's even possible. But who knows?
Apparently people in the tropics can stand solar radiation better than those in the temperate or colder zones. They are naturally genetically adjusted. So: 'Who knows?' It might happen...
So for that we need to take kids put them in space and feed them and ask to live there for years , and after a generation or two they will withstand it.
