In a void in the solar system, the 'Kwafak' spacecraft is flying fast in the void at a speed of more than 200 kilometers per second. This speed has exceeded the fastest historical record of human history, and its speed is still Soaring.

But the void is too vast, even at a speed of hundreds of kilometers per second. In the boundless void, the Kuafu spacecraft still seems to be still at the origin, and it seems that it will always be at one point without any Change, not to mention the universe, the solar system is too big.

Inside the Kuafu spacecraft, everyone is lying on their own space chairs, while using the virtual watch they carry with them to play games and chat with friends and relatives in the virtual world, they also feel that the spacecraft is accelerating. Powerful push back.

The engine of the Kuafu spacecraft has a powerful thrust of 800 million tons, and the mass of the spacecraft itself is only a million tons. Even if it is everything in the spaceship, its mass is only over 2 million tons.

This point of quality is insignificant compared to the thrust of 800 million tons of engines.

"Accelerate ~ Accelerate ~"

The speed of the spacecraft is still soaring, but in order to consider the pressure resistance of the crew on the spacecraft, the acceleration process of the spacecraft is not too fast, it is a continuous acceleration process.

For this scientific expedition around the solar system, the distance needed to sail was really too long. Without sufficient speed, the spacecraft did not know the year of the monkey to complete the scientific expedition.

The earth gradually becomes smaller in the field of vision, and finally disappears slowly. With the naked eye, no trace of the earth can be seen at all, according to calculations and planning by scientists.

The first stop of the Kuafu spacecraft was Mars, and went to Mars to investigate.

Mars and Earth have too many, too many similar places, both have the atmosphere, the speed of revolution is similar, the speed of autobiography is only 41 minutes apart, and the surface temperature difference of Mars is not too large, of course, this is compared to the solar system. For other planets.

Moreover, Mars, like Earth, is in a habitable zone considered by scientists in the solar system. The so-called habitable zone is a zone where scientists believe that only within a certain range can it be born and live.

For example, in the solar system, the habitable zone refers to the range of the four planets Mars, Earth, Venus, and Mercury. In this range, because it is closer to the sun, the light is sufficient, and the temperature is not too cold, which is suitable for the birth and reproduction of life. .

Once it exceeds this range, because the distance is too far from the sun, the light is not good, and the temperature is very low, it is impossible to have the birth and reproduction of life.

Therefore, with the asteroid belt as the boundary, the inner circle can also be called the inner circle of the solar system, and the outer circle can be called the outer circle of the solar system.

Because Mars has too many similarities with Earth, it has always been considered by scientists as the most likely planet to be used for interstellar immigration. There are also many sci-fi movies and science fiction about Mars immigration, Mars transformation, and so on. .

In addition, scientists also analyzed all existing issues and concluded that Mars may have produced a very prosperous life in the history of the Earth, but it was later unknown why Mars would wither and eventually change. Become a dead planet.

Scientists are very interested in exploring above Mars, looking for life on Mars, searching for traces of life on Mars, and taking a look at whether Mars might become a planet for human migration.

Of course, if Mars really had life, you can also investigate the cause of Mars's death by investigating Mars, check to what extent Mars' life evolved, and whether advanced life was born. The end of senior life is anything but.

There are too many, too many things waiting for scientists to explore and discover.

So when the figure of Mars appeared in the view of the Kuafu spacecraft, the scientists on the entire spacecraft became excited one by one.

The Kuafu spacecraft is getting closer and closer to Mars, and its speed is slowly decreasing. The gravity of Mars is only about 40% of the Earth ’s gravity. This means that if the Kuafu spacecraft wants to be captured by Mars ’gravity, The speed must be reduced to a low enough level.

"It's hard to imagine how prosperous Mars would have been if it ever had life."

Dragon battle air passed through the telescope above the spacecraft, and began to observe Mars from a distance.

Unlike Earth, which is a blue jewel, Mars is a red-yellow planet. Its atmosphere is very thin and only about 1% of Earth's atmosphere, so the surface of Mars can be clearly seen in the sky.

Very barren, a world dominated by red.

"Even if there was life, it is not known how many billion years ago. The entire solar system has a history of 4.6 billion years. In such a long time, the history that we humans know now is trivial."

Next to the dragon battle sky, Huang Zhibin is also constantly observing the red planet in the void. As a cosmic astronomy scientist, he is also very interested in the history, evolution and development of the solar system.

The other part of the spacecraft, the simulated ecological area, is the same as Liu Daoming and Li Jingxuan, who graduated from Xinghe University of Science and Technology with their first majors in biological sciences. While studying the growth of plants in a weightless environment, they are also discussing life on Mars.

"In a weightless environment, plant genetic mutations are very frequent, and the impact on animals is even greater. In space, almost all these mice have lost the ability to reproduce the next generation. It is estimated that in a weightless environment, The secretory system, genetic system, and so on of the animal have affected. "

Liu Daoming carefully observed the plants and animals in the simulated ecological zone. After observing and researching in space for a long time, he also found that the weightless environment has a great impact on plants and animals. Very disturbed, difficult to adapt, and often do not eat or drink.

"Stop this, do you say there will be life on Mars?"

"There is water on the north and south poles of Mars. With water, it is very likely that life can be born, especially the environment of Mars is relatively mild. I estimate that there will be birth of life under the north and south glaciers of Mars. "

Li Jingxuan looked out of the window. A red planet stood quietly in the void. Scientists studying biology were obsessed with finding the origin of life.

Just as cosmic astronomy scientists want to figure out the origin and evolution of this universe, and want to figure out how big this encounter is, bioscientists are also looking for the origin of life, trying to figure out to what extent life will evolve in the future.

"There have always been two views on the origin of life. One is an idealistic view that life and everything are created by the so-called God. Another materialistic view is that with the continuous development of modern technology, It appears that Earth's life is accidentally produced by a meteorite or a chemical reaction on the Earth itself. "

"I do n’t want to say idealistic views. Micro-level views are deduced based on existing biological science and technology, especially Darwin ’s theory of evolution. In addition to the emergence of genetic technology, almost all living creatures are pursuing and exploring the source. You can trace to the oldest and simplest life. "

"So now scientists basically think that life is a comprehensive reaction of chemistry, physics and so on. Different molecules interact with each other and are mixed to produce original organic molecules with DNA. DNA has two characteristics: first, it can make amino acids, Second, it can replicate on its own. The two traits of DNA are also the basic traits of bacterial organic organisms. Bacteria are the simplest form of life in life, and are the oldest fossils we can find at present. "

Speaking of the origin of life, Liu Daoming suddenly came to the spirit. As a biological scientist, he has also been thinking about the very serious question of the origin of life ~ lightnovelpub.net ~ but the history of the earth has been One billion years, the history of life is also very long. What happened in the long years calculated in billions of years, modern times can only be researched and inferred through some fossils, but it is very important to trace the roots. difficult.

Although life is also composed of various molecules, all kinds of things in life are dead when taken out individually, but when combined together, it is life, very magical!

You can imagine that these substances in the human body are very common in nature, but after the combination, people are born, this magical life.

"Life is not necessarily related to water, but our current cognition is that without water, there can be no life, but there are many ideas in science fiction movies and science fiction. Carbon-based life, silicon-based life, Energetic life, mechanical life, etc. "

"The universe is too big. We know too little, too little now. We are sitting on the sky watching the sky."

"A planet with water does not necessarily have life, and a planet without water does not necessarily have no life. I think that life may exist widely in the universe. Maybe life can be found on Mars."

Liu Daoming put down his work, came to the window of the spaceship, and looked at the planet in the void. Although not as touching as the earth, it exudes an intoxicating halo of life.

But at this time, Liu Daoming was anxious to fly to Mars immediately to search for traces of life at once. Humans are too lonely. So far, they have not found any extraterrestrial life, so that sometimes humans sit in the sky and watch the sky. It is said that human beings are the only life in this universe.
