We'll never go live on Mars. Not ever. Proponents and promoters speak of the need to colonize planets in order to reduce congestion here on earth.
They tell us we could live underground, or in specially built facilities. They say children will be born on Mars.
It's nonsense.
We will never live on a planet where venturing outside would mean certain death. Mars is a place where our bodies would rapidly deteriorate first from the lower gravity and second from the constant bombardment of deadly rays generated by the sun. Scientists know this. But they want "research money" so they promote this fantasy. You want to live in someplace harsh because earth is too crowded?..... Consider the far north.
There is room on every continent that reaches into the arctic. Just pick a spot and colonize - Iceland; Greenland; Canada. Or go south to the Antarctic. Or go underwater if you want a real challenge. Each of those are infinitely cheaper than going to mars. You could go outside and survive and babies could be born. And if you get tired of it you can go home.
Mars?..... Nah. Never. But I'd be interested in your take.
