The composition of human migration to Mars

In real life or work and study, everyone is familiar with composition. Composition is a verbal activity in which people express their thoughts in written form. What kind of composition can be called an excellent composition? The following is my collection of essays on human migration to Mars. Welcome to share.

Human Migration to Mars Composition 1 As early as more than a century ago in science fiction, human beings began to walk on Mars, but until today this is only an idea. But many people firmly believe that the question is not whether humans can land on Mars, but when and how to get there. So far, no one knows exactly how to reach Mars in the most convenient and labor-saving way. Some people estimate that it will cost 60 billion dollars or more for humans to land on Mars. However, Robert Zublin, president of the Mars Society, thinks that the figure should be $30 billion to $40 billion, which is equivalent to the cost of the Apollo moon landing program. Zublin published a book called Migration to Mars, which outlined the grand blueprint for human settlement on Mars.

Why do humans always yearn for Mars? Because according to the current observation, Mars is the most likely place to become the second home of mankind. Although the temperature on Mars is minus 200℃, the environment on Mars is the most similar to that on Earth among all the planets in the solar system. The diameter of Mars is about half that of the Earth, and the gravity on the Earth is equivalent to 1/3 and the atmospheric concentration of1100. Most importantly, the probe found water at the frozen poles and below the surface of Mars. Every two years, Mars will approach the Earth once. Last summer, Mars came to a place 55.76 million kilometers away from the Earth, which was its closest to the Earth in 60,000 years.

Zublin said: "People really want to know whether there is life outside the earth, and Mars may be the key to solve this problem. On Mars, even if only microorganisms in the original state can be found, it means that human-like life does not only exist on the earth. "

Louis Friedman, president of the Planetary Society, said that the basic question that human beings want to answer is, where do people come from? Where are you going? "The most attractive thing about Mars is that it may help us understand the origin and destination of life." "Moreover, Mars is the only place where we know that human beings have the opportunity to immigrate, which will prove that they will not stay on the earth forever; If we can immigrate to Mars, then the earth may be our only home, and we will have to re-examine the relationship between human beings and the earth. "

Human Migration to Mars Composition 2 2399 has arrived. Due to the heat island effect, the earth warms and the sea level rises, and many lands become Wang Yang. Due to the decrease of green plants, some land sandstorms are rampant. Environmentalists of the earth have to rush out of the earth to find another habitable planet.

According to our detection, Mercury is too close to the sun. Moreover, the temperature difference between day and night is particularly large, reaching above 60℃ during the day and-20℃ at night; It often rains with sulfuric acid on Venus ... After in-depth investigation, we decided to conduct experiments on Mars, the "twin brother" of the earth. My colleagues and I started flying the Explorer 123 spacecraft to Mars. In space, I saw many twinkling stars, blazing sun, lovely earth and mysterious black holes.

After a half-day trip, we came to Mars. I took out the cosmic thermometer from the spaceship and began to measure the temperature. Two seconds later, the thermometer showed that most places were very suitable for human habitation. We use a space crusher to crush the glaciers in the southern and northern poles of Mars into liquid water, which flows into the potholes on the surface of Mars and becomes rivers, lakes and seas. So when the captain decided to settle on Mars. We use satellite transmission system to send information to people on earth. As soon as people on earth heard this message, they were ready to transfer some people to settle down. We immediately built a house with some space materials, and also built a solar power plant and a reclaimed water plant.

After people came to Mars, they invented many practical things, such as spacecars and spaceships. To thrive here and live a happy life.

On the rest day when humans moved to Mars, they left their homes and the streets were blocked by vehicles of all sizes. The horn kept ringing, and a steady stream of waste gas stinked. A good mood suddenly cast a shadow over the blue sky. Hey! Our world today is very chaotic, and this small street is just the tip of the iceberg.

So, hope can't help rising in my heart. If we could move to Mars, it wouldn't be like this.

Loggers on the earth cut down wood day and night, and many dense forests became bare deserts. The flowers gradually withered, the birds stopped singing, and all that was left was wooden furniture. If we immigrate to Mars, we will certainly have enough new materials to replace wood. The forest can stick to its original mission, that is, grow, grow into a sea of green land, and birds can be heard everywhere.

Many factories on the earth will discharge a lot of sewage from time to time, making the crystal clear river water as black as ink. There are also many people who throw a lot of rubbish into the river and kill those carefree little fish living in the water. If you immigrate to Mars, the river there is a trickle and crystal clear, and the fish live a happy life in the water.

There are many cars on the earth. Although the speed is very fast, the toxic exhaust gas is quietly eroding the ozone layer, which once helped us block ultraviolet rays and made great contributions, making the air more and more impure. Not only that, many people get no exercise and get fatter and fatter. If we reach Mars, we will never let the air on Mars be as dirty as the air on Earth. Everyone will never drive again and make themselves healthier and stronger; Make the world a better place.

Although these are just fantasies, it would be great if they can really come true! Of course, all this is only our last "killer weapon", and we should cherish the earth more with hope!
