Mars or Earth-Where do you choose to live?

At present, the total population on the earth exceeds 7.6 billion, and the population continues to grow. In about 20 years, the world population will exceed 654.38+00 billion. The earth is becoming more and more overwhelmed, and the population of the earth is getting closer and closer to the carrying limit. Interstellar migration will be an important choice for us. In the solar system, Mars is the most similar to the Earth and not far from it. Elon Musk, a legendary American space scientist, also boldly stated that he would send 1 10,000 people to Mars.

Let's learn about Mars first. The diameter of Mars is about 53% of that of the Earth, and its mass is 1 1% of that of the Earth. Due to the axial tilt, the rotation period is similar to that of the earth, and one circle is about twice that of the earth. There are sand dunes and gravel on the surface of Mars, and there is no stable liquid water body. The atmosphere dominated by carbon dioxide (95%) is thin and cold. Mars has two natural satellites. On September 28th, 20 15, NASA announced the existence of running water on Mars. The nearest distance from Mars to the Earth is about 55 million kilometers, and the farthest distance is over 400 million kilometers. Close contact between them occurs about once every 15 years. The average temperature on Mars is about minus 55 degrees Celsius, the lowest temperature is zero 133 degrees Celsius, and the highest temperature is 27 degrees Celsius. It can be seen that the average temperature of Mars is lower than that of the Earth, and the average temperature is about the same as that of the South Pole.

How do we transform Mars? The key is to form an ecosystem and an anaerobic biosphere on the surface of Mars. First, we installed an artificial magnetic field on Mars to prevent solar radiation. A lake with a diameter of about 20 kilometers was found in the stratum of Mars, and groundwater can be exploited in some way. Electrolyzing carbon dioxide in the Martian atmosphere to produce oxygen and thicken the Martian atmosphere; Raise the temperature of Mars by heating, and raise the temperature to a temperature suitable for life. Through hard work, the basic environment of life is already available. Then deploy all kinds of microorganisms on the surface of Mars, plant plants, feed insects, grow grain, feed poultry and livestock, and gradually realize self-sufficiency of Mars.

In addition, if the distance from Mars to the Earth is 6000-1200,000 kilometers, then the speed of our manned aircraft is about 30,000 kilometers per hour, so it takes 2000 hours to 4000 hours, about 3-6 months, which is not too far. You know, in ancient times, it took at least three months to walk from China to Europe at 6000 kilometers!

Immigrating to Mars is not far away.
