Research by a Martian colonization enthusiast


When I was a kid, I dreamed about space adventures. I knew: by the time I grew up, humanity would have reached other planets, and I would be a scout among stars.

For years I watched hopelessly how people spent money and effort on anything but space exploration. I almost gave up. Then, Elon Musk appeared. He gave me — and thousands of other dreamers — a feeling that we still might see human feet touching the red dust of Mars.

The feeling is not enough. I needed proof. I wanted to be sure: this time, I would not be fooled.

This is what I found:

12. Will we ever colonize outer space?
“That depends on the definition of ‘colonize.’ … if the idea is to construct a self-sustaining environment where humans can persist indefinitely with only modest help from Earth… then I’d say this is very far in the future, if it’s possible at all…We haven’t bothered to colonize areas underwater on Earth yet. It’s far more challenging to colonize a place where there’s hardly any atmosphere at all.”
— Catharine A. Conley, NASA planetary protection officer

“That’s an interesting idea,” I thought. “Underwater is almost another world.”

I researched that subject, and this is what I found.

1. Living in a submarine city is psychologically more comfortable.

What would you prefer: spending seven months in a metallic can in open space, or enjoying a week voyage in the Atlantic Ocean?

Seven months is a considerable period. Astronauts don’t spend more than half a year outside Earth. Studies show they are subject to depression, insomnia, anxiety, fatigue, boredom, and emotional instability, nonetheless. Professor Nick Kanas, a Nasa-funded expert in the psychological effects of space exploration, says that when Earth is out of view for an extended time, “crewmember psychology may result in increased feelings of isolation, homesickness, dysphoria, or even suicidal or psychotic thinking.”
