2066 Minus

John's temporary office in the Pentagon was small, but it did not bother him. He is busy preparing his speech for the first round of parliamentary briefing. He always feels good at explaining difficult problems to students and colleagues, but it goes far beyond difficulties. Knocking on the door opened his work. "McKinney captain?" "The main Timberine, that was a surprise." "This is a colonel, but please do not worry," Tinlin said.

Last week, the Financial Times decided to create a theoretical history record of 2066 to explain the aggressive political events of the past few months (http://on.ft.com/2bOplXy ). This does not make reading a lot of fun. I thought that I would try turning this over and trying to write a slightly more optimistic view This is the only problem I know.

I have been thinking about it. I thought about what will happen in 50 years. From 2016 to 2066, some of us may have died and most of our parents will do the same. Some of us may retire and may be enjoying our golden age, but others may still be chasing their dreams. Most of us are experiencing the pain of life such as unemployment, divorce, death of loved one, and many broken hearts. The world will also see fundamental changes. As technology improves, we may have solved food shortage and poverty problems. We may also see the beginning of positioning ourselves as a species of the Milky Way with new colonies on Mars.

Mars is cooler than the earth, because it is far away from the sun. The average temperature is minus 80 degrees Fahrenheit (minus 60 degrees Celsius), but it varies from 195 degrees Celsius (125 degrees Celsius) to 70 degrees Fahrenheit (20 degrees Celsius) near the equator near the winter pole. . The average density of atmospheric air rich in Martian carbon dioxide is about 100 times that of the Earth, but it is thick enough to support weather, clouds and wind. In winter, carbon dioxide is frozen from the air of Mars, so the density of the atmosphere varies according to the season. In ancient times, the atmosphere becomes thicker and can support the flow of water on the surface. Because there is no global magnetic field in the Martian atmosphere, lighter molecules in the Martian atmosphere escape with solar wind pressure. NASA's MAVEN (Mars atmosphere and volatile evolution) mission is studying this process
