Astrophysicists have officially announced: the most comfortable place in the outer solar system, where a person can not only survive, but feel almost happy, is Titan. Satellite of Saturn. The same one where instead of rain there is gasoline, and instead of granite underfoot there is water, frozen at minus one hundred and eighty so that it cannot be split with a sledgehammer.
In short: scientists from the American Chemical Society have calculated that a colony on Titan can be made autonomous. There is everything that we are accustomed to consider a deficit on Earth - water (in the form of granite ice), methane (in the form of lakes that people don’t go swimming in), nitrogen (all in the air) and silence, because there is no one to shout there anyway.
Gravity is one seventh of Earth's. Atmospheric pressure - presses pleasantly, like a good blanket. In total, this means that a person on Titan will be able to fly. Literally. I tied fabric wings to my hands - and forward, without a pass into the sky and without an air traffic controller. The Martians have dreamed of a colony all their lives, but the Titans will simply wave their arms and sunbathe in the orange sky.
There is no oxygen on Titan. But there is ice, which local factories (at nuclear reactors, because the sun is there - the cat cried) will melt and drive through electrolysis. If you get oxygen, breathe. You get hydrogen, combine it with nitrogen, get ammonia, and here’s rocket fuel for you to go home and tell you how cool it is. And the lakes of liquid methane and ethane are just a free refueling, if anyone else doubted that Titan is a paradise for those who are not afraid of the cold.
Arthur C. Clarke once said that any sufficiently advanced technology is indistinguishable from magic. Titan astrophysicists confirm this literally: ice is converted into air, nitrogen into rocket fuel, and weak gravity into wings. Robert Heinlein dreamed that a person would live wherever he could install a dome and turn on a reactor. On Titan, a dome is not needed - the atmosphere holds itself, and the reactor heats the ice. Jules Verne generally believed that he would fly to the Moon on a cannon - and, looking at the titan wings, you understand: he simply underestimated that it was enough to just jump and wave.
So while astrophysicists are dividing Titan, humanity is mastering the main technology of colonization: how to breathe when there is no oxygen, and methane is everywhere.
