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

For Mars, it also gives us such a feeling.

Mars is indeed a fascinating place, mysterious and full of temptations, so that countries around the world have been trying to explore the red planet.

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

And today, Mars has finally welcomed its first visitors, and unlike the dumb machines, this is a group of truly intelligent creatures.

"It's finally here, Mars!"

After the "Yuanhang" spacecraft stopped steadily in the orbit of Mars and turned off the main thruster, it began to orbit Mars by inertia, and those members all gathered at the nearest window to look at the red planet that mankind has longed for for a long time.

"See, chairman," Musk stood by the window, pointing to the huge mountain range to show the robot controlled by Dong Chen, "that's Mount Olympus, a shield volcano on Mars and the highest known mountain in the solar system." ”

It is 21,229 meters above the datum, more than twice the size of Mount Everest on Earth, and is currently a well-deserved "roof of the solar system". ”

"Yes," Dong Chen looked at the tall mountain range and sighed, "It's too high, this is the magic of nature." ”

"And in the past, such a view could only be seen in science fiction movies, but today you are standing in the orbit of its planet."

Speaking of Dong Chen's robot, he looked at Musk, and then at the other team members by the window, and said enviously, "Although I also have a feeling of being there, my situation is still similar to watching a movie, I really envy you." ”

"Chairman, you don't have to be envious, maybe the next time you come to Mars, you will be able to follow the team, and the spacecraft should be faster and more advanced in design by then, and the group should not worry about your safety." Musk said with a smile.

In this regard, Dong Chen could only say that he would follow the fate, who knows when the time comes.

He just wants to wait for the earth to be successfully upgraded, and when humans become transplanetary species, he should be able to go out and wave casually, and at that time, it is estimated that the mysterious "big filter" stage should be able to pass.

With the current progress of the earth, because of the assistance of the "Atlantean civilization", it should be possible to wait for controlled nuclear fusion to be completed, and it should be possible within ten years.

When the spacecraft reached the orbit of Mars, they should also think about landing, so after letting the crew enjoy the scenery for a while and relax the nervous or tired mood caused by the long space trip, Musk called everyone to a meeting.

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

Dong Chen will not participate in their meeting, because this is not a project he wants to take care of, the reason why he came here is to be able to see the scenery of Mars from the normal way, after all, he is also very curious about some situations on Mars.

If it weren't for the complicated situation on the earth now, he didn't want to leave the earth, maybe he would have come with the team a long time ago, if he really wanted to come, others wouldn't be able to stop him.

So when they were in a meeting, Dong Chen directly controlled the robot to carry out a spacewalk, which was called to check the external structure of the spacecraft.

He fastened a string to a hook around his waist, activated the electromagnetic device in his foot, and walked around the outer shell of the ship.

At his feet is a spaceship more than 200 meters long, with Mars overhead, which is so huge because it is too close, and then surrounded by the vast and deep dark cosmic space.

There is no familiar colorful earth, no familiar gray moon, they are just a bright spot you can see, such a strange and empty environment, if those who have deep-sea phobia, cosmic phobia or giant phobia can see it, it is estimated that they will go into shock.

Mars is the fourth planet in the solar system from the inside out, and it is the seventh largest planet in the solar system.

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

The southern hemisphere of Mars is an ancient crater-laden 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 in the solar system, the one Dong Chen saw before.

At a distance of about tens of thousands of kilometers from Mars, there are two very small stars, which are moons of Mars.

In Chinese, the name Mars conjures up images of "fire" and heat, but in reality, the red planet is unusually cold and dry.

Still, Mars remains the most Earth-like planet in the solar system. It's just that it's smaller than the Earth, and the atmosphere is much thinner than the Earth.

The atmospheric pressure of Mars is only 7/1000 of that of Earth, and its atmosphere is mainly composed of carbon dioxide, and other components include nitrogen, argon, oxygen, etc. The specific gravity of water in the Martian atmosphere is only 0.03 percent, so the surface of Mars is unusually dry.

Although there is very little water in the Martian atmosphere, there is still a lot of water in it, although it is now in the form of solid water.

Scientists have long found that many areas on Mars show signs of erosion, and that criss-crossing riverbed seems to tell us that there was once liquid water on Mars, and there is still a lot of water, and it has gathered into lakes and even oceans.

Scientists have explained that in the early days of Mars' formation, the planet was encased in a thick cloud of carbon dioxide, which led to a powerful "greenhouse effect", in which the heat on the surface of Mars was blocked by the clouds and could not be dissipated into outer space, raising the temperature and allowing water to exist in a liquid state.

At that time, Mars was warm and humid, and it may have given birth to life, so humans have always had a soft spot for Mars, thinking that one day they will land on the surface of Mars like the moon and conduct field investigations.

And now, in the spacecraft, Musk and they are meeting to discuss, is about landing on Mars.

The average temperature on Mars is minus 55 degrees Celsius, and the temperature difference is large. During the summer daytime, the temperature can reach as high as 20 degrees Celsius, while in the winter it can drop to more than 100 degrees Celsius.

Strong winds are often found on Mars, which often leads to widespread dust storms, even those that can sweep across the planet.

This is also what the directors of those sci-fi films like very much, because only in this way will the astronauts who land on Mars be unlucky, and the astronauts will be unlucky, and the plot can develop.

However, the actual situation of Mars is much better, and its strong wind is also a "strong wind" in the sense of Mars, in fact, it just looks like a huge momentum, but in fact, it can blow some sand, which is still because of the small gravitational pull of Mars.

Typical thunder is loud and rain is small.

However, the impact on the equipment that landed on Mars is still not small, if the dust flies up and attaches to the solar panels, or drills into some crevices, the impact on the equipment is still quite large.
