Chapter 808 Taking a break in Mars orbit

Mars is one of the closest neighbors to the earth. It is just like your paper wife. You want to get close to it, but you can't, so in your eyes, they have always maintained a sense of mystery and freshness.

Mars also gives us such a feeling.

Mars is indeed a fascinating place, mysterious and full of temptations. Countries around the world have been working hard to explore this red planet.

But until today, we still know very little about Mars.

Today, Mars finally welcomed its first batch of visitors. Different from dull machines, these are a group of truly intelligent biological visitors.

"Finally, Mars!"

After the "Yuanxian" spacecraft stopped steadily in the orbit of Mars and turned off the main thruster, it relied on its inertia to start orbiting Mars, and the members all gathered at the window closest to them. On the other side, I looked at the red planet that mankind has longed for for a long time.

"Did you see it, Chairman?" Musk stood by the window and pointed to the huge mountain range for the robot controlled by Dong Chen. "That's Olympus Mons, a shield volcano on Mars and the largest mountain in the solar system." The highest known mountain in the world."

"It is 21,229 meters above the base level, more than twice as tall as Mount Everest on Earth. It is currently the well-deserved "roof of the solar system." People in the past could not imagine that there would be such a tall mountain on a planet."

"Yes," Dong Chen sighed as he looked at the tall mountain range, "It's too high. This is the miraculous workmanship of nature."

"And in the past, such scenery could only be seen in science fiction movies, but today you are standing in its orbit to see it."

While talking about Dong Chen's robot, he looked at Musk, then at the other team members by the window, and said with envy, "Although I also feel like I'm on the scene, my situation is still the same as watching a movie. It's really Envy you."

"Chairman, you don't have to be envious. Maybe when you come to Mars next time, you can come with the team. Moreover, the spacecraft will be faster and more advanced in design, and the group will not be able to do it." I'm worried about your safety." Musk said with a smile.

Dong Chen could only say that he was resigned to the situation. Who knows when the time comes.

He just wants to wait for the earth to be upgraded successfully, and when humans become a multi-planetary species, he should be able to go out and wander around at will. By then, it is estimated that the mysterious "Great Filter" stage will be over.

Based on the current progress of the earth, with the help of the "Atlantis Civilization", it should be possible after the controllable nuclear fusion is completed, which should be within ten years.

Once the spacecraft reached Mars orbit, it was time for them to consider landing. So after letting the crew enjoy the beautiful scenery for a while and relax from the tension or fatigue caused by the long space travel, Musk called everyone Went to a meeting.

As for Dong Chen, with the assistance of the intelligent system, he took several other robots to start repairing the spacecraft to keep it in optimal condition.

Dong Chen will not participate in their meeting, because this is not a project that he has to manage in the first place. The reason why he is here is to see the scenery of Mars from a normal way. After all, he is also very familiar with some conditions on Mars. curious.

If he didn't want to leave the earth because of the current complicated situation on the earth, he might have come with the team long ago. If he really wanted to come, no one else could stop him.

So while they were having a meeting, Dong Chen directly controlled the robot to conduct a space walk, euphemistically called: inspecting the external structure of the spacecraft.

Just fasten a thin rope to the hook on the waist, then activate the electromagnetic device on the feet, and start sliding on the outer shell of the spacecraft.

Underfoot is a spaceship more than two hundred meters long, above the head is Mars, which looks huge because it is too close, and then around him is the vast, deep and dark space of the universe.

There is no familiar colorful earth, no familiar gray moon, they are just a bright spot that you can see. Such a strange and empty environment, if it is seen by those with deep sea phobia, cosmic phobia or giant phobia, it is estimated that it will be difficult to see it. They are all going into shock.

Mars is the fourth planet in the solar system from the inside out, and its volume ranks seventh in the solar system.

Because the rocks, sand, and sky on Mars are red or pink, the planet is often called the "Red Planet."

The southern hemisphere of Mars is an ancient, cratered plateau similar to the Moon, while the northern hemisphere is mostly made up of young plains.

The 24-kilometer-high "Olympus" mountain above it can be called the highest mountain range in the solar system, and it is the one Dong Chen saw before.

About tens of thousands of kilometers away from Mars, there are two very small stars, which are satellites of Mars.

In Chinese, the name of Mars reminds people of "fire" and heat, but in fact, the red planet is extremely cold and dry.

Despite this, Mars remains the most Earth-like planet in the solar system. It's just that its volume is smaller than that of the earth, and its atmosphere is much thinner than that of the earth.

The atmospheric pressure of Mars is only seven thousandths that of Earth. The main component of its atmosphere is carbon dioxide, and other components include nitrogen, argon, oxygen, etc. The proportion of water in the Martian atmosphere is only 0.03%, so the surface of Mars is extremely dry.

Although there is very little water in the atmosphere of Mars, it still contains a lot of water, although it currently exists in the form of solid water.

Scientists have long discovered that many areas on Mars show signs of erosion, and the criss-crossing river beds seem to tell us that there was once liquid water on Mars, and there was a lot of water. They gathered into large and small lakes and even oceans.

The explanation given by scientists is that in the early days of the formation of Mars, the planet was wrapped in thick carbon dioxide clouds, resulting in a strong "greenhouse effect." After being radiated by the sun, the heat on the surface of Mars was blocked by the clouds and could not be dissipated to the outside. layer of space, causing the temperature to rise and allowing water to exist in a liquid state.

At that time, Mars was warm and humid, and may have given birth to life. Therefore, humans have always been fond of Mars, thinking that one day they would land on the surface of Mars and conduct on-the-spot investigations like they did on the moon.

And now, what Musk and the others are discussing in the spacecraft is about landing on Mars.

The average temperature on Mars is minus 55 degrees Celsius, and the temperature range is large. In its summer daytime temperatures are as high as 20 degrees Celsius, while in its winter temperatures can be as low as minus one hundred degrees Celsius.

Mars often has strong winds, which often lead to large-scale dust storms, even large dust storms that can sweep across the entire planet.

This is also what directors of science fiction films like very much, because only in this way will the astronauts who land on Mars be unlucky. If the astronauts are unlucky, the plot can develop.

However, the actual situation of Mars is much "better". Its strong winds are also "strong winds" in the Martian sense. In fact, they only look powerful, but they can actually blow up some sand. This is because Mars has a small gravity. s reason.

Typical thunder is loud and raindrops are light.

However, the impact on the equipment for landing on Mars is still not small. If the dust flies up and adheres to the solar panels, or gets into any gaps, the impact on the equipment will be quite large.
