The site for landing on Mars was chosen as a relatively flat sandy area, where two other spacecraft from Future Tech were docked. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Mr. Zhang, the Martians welcome you. ”

When Zhang Wei's family stepped on the land of Mars in spacesuits, they were immediately warmly welcomed by 40 astronauts. The 40 astronauts stayed behind in the two spacecraft, while the other 160 astronauts were scattered around Mars to investigate the planet.

Zhang Wei couldn't help laughing when he heard this, "It's only been a month on Mars, and you've become Martians?"

"If you come to Mars, you are Martians, and Mr. Zhang, you are also Martians now. ”

The astronauts laughed and said that some of them had been away from the earth for more than four months, and they all had a different kind of intimacy when they saw the visitors from the earth at this moment.

"Hey, how is the sun blue on Mars?"

At this time, my father was suddenly surprised.

"It's really a blue sun, it's really unusual!"

Mom, Ren's father, and Ren's mother also looked at the sky, and it was sunset, only to see a blue sun hanging in the sky on the horizon, which was beautiful and amazing.

"This is the scattering of light, the Martian atmosphere is thin, the dust particles are more and larger, mainly Mir scattering, scattering red light with the same wavelength as its own particles, the red part of the sunlight in the direction of the line of sight is scattered, so the sunset will be blue. And the Earth's atmosphere scatters blue light, so the Earth's sunset is orange-red. ”

Zhang Wei explained with a smile, "When we complete the transformation of Mars and let the dust particles in the atmosphere fall to the ground with the rain, the sun will look like the earth from Mars." ”

It soon got dark, and Zhang Wei's family had a small party on the spaceship, listening to the astronauts introduce the novelties they had discovered on Mars, and then began to rest and recharge.

Next.

Zhang Wei's family got up early and prepared to start their journey to Mars.

However, Mars doesn't seem to welcome them as tourists, and before they get out of the spaceship, the spaceship's mastermind warns, "Boss, there's a super tornado sweeping through here, it's expected to arrive in 10 minutes, please don't leave the spaceship for safety reasons." ”

This tornado, with a diameter of more than 40 meters, a height of more than a kilometer, and a wind speed of more than 60 meters per second, carries a large amount of sand and dust, which is different from the sand and dust on the earth, they are red Martian sand mixed with a large number of iron oxide particles, if humans in spacesuits are involved, the spacesuits have a high chance of being worn out on Mars, and then, humans will be submerged in endless Martian sand. These very fine Martian sands also carry microstatic electricity, which can attach to the surface of any object, and even burrow into moving objects inside the machine, causing damage to the machine. In the film "The Martian", the main character Mark has to wear an extravehicular spacewear brush every day to clean the dust from the solar array outside the cabin. However, the energy shield on the spacecraft can effectively keep the sand and dust out.

It didn't take long for the super tornado to sweep over, the red sand and dust hit the energy shield, the crackling sound kept coming, and Zhang Wei's vision turned all red, like an apocalyptic scene.

About five minutes later, the super tornado was gone.

Zhang Wei's family also walked out of the spaceship, came outside, looked at the super tornado in the distance, and sighed, "The current Martian environment is really bad!"

In fact, storms on Mars are frequent, and almost every year in late spring and early summer on Mars, there is a months-long storm sweep, and the storm carries sand and dust all over the sky, forming a unique Martian scene. The entire surface of Mars is the result of such storms over a long period of time. So most of the whole of Mars is desert.

It wasn't long before two astronauts flew in two flying cars, specially designed for the exploration of planets in outer space, with huge carriages that could carry a lot of equipment.

Under the leadership of these two astronauts who are familiar with the Martian environment, Zhang Wei's family began their journey to Mars.

The first stop is to inspect the land carved up by the future technology company on Mars, this more than 10 million square kilometers of land Zhang Wei is excited, full of pride, although these lands are now just deserts, but will soon become suitable for human habitation, and this is just the beginning, he wants to get more and more land in space, first set a small goal, that is, like the movie "Alien" Wieland Tangya Company has more than 300 colonized planets.

In addition to the astronauts of Future Technology, they also encountered other objects from the earth, that is, the United States' "Spirit", "Opportunity", "Curiosity" and other Mars probes. Among them, the nuclear battery of the "Curiosity" Mars rover can still work normally, and a photo of Zhang Wei was taken and sent back to Earth, NASA (National Aeronautics and Space Administration) staff thought that Curiosity had photographed aliens at first, and then take a closer look, isn't this the genius scientist Zhang Wei in China? They suddenly sighed in their hearts that the space technology of the future technology company has developed too fast, and it only took a few years to surpass the United States' more than 60 years of technological accumulation, and the United States has been left far behind.

This photo was immediately published on the Internet, causing heated discussions, people envious, holding a wedding on the moon, going to Mars for a honeymoon, Zhang Wei, you are too dashing, when can we ordinary people also enjoy such a romance! There are still many people who feel extremely proud, that is, the Chinese, the United States has been for so many years, and it is only to launch unmanned probes to Mars, the first to land on Mars is still us Chinese, and the first to travel to Mars is also us Chinese!

After basically visiting Mars, Zhang Wei did not return immediately, but waited for another three days, because the expedition of the other astronauts would end in three days.

"Guys, we're home!"

Three days later, Zhang Wei announced to the astronauts.

"Home! Home!!"

All the astronauts are cheering, after so long in this desolate space, many of them are physically and mentally exhausted, they miss their families on Earth, they miss the land on Earth, they miss the air on Earth. Moreover, people live and develop in the environment of the earth's gravity, and leaving the earth to go to other planets is not like going from Beijing to New York, where there is almost no physical adaptation problem.

On the contrary, if human beings go to a planet with a much higher gravity than the earth, they will behave weakly, and they will even gasp for breath when they walk, and their hearts will not be able to bear the load! If they go to a planet with a much lower gravity than the earth or no gravity, they will behave like a gorilla with developed limbs, and they will be extremely strong, but the weakening and disappearance of gravity will cause changes in the human body, resulting in symptoms such as osteoporosis and muscle atrophy, in short, physical degeneration. When they live on a low-gravity planet for a while, and when they return to Earth, it will be difficult to adjust to Earth's gravity.

The surface gravity of Mars is only 2/5 of that of Earth, and if you stay in this environment for a long time, your body will inevitably degenerate. The same goes for these astronauts, even if they can rest on the spacecraft at night, they still have to go out during the day, so they need to go back to Earth to recuperate for a while.

On the problem of planetary gravity, Zhang Wei has also been trying to find a way to solve, there are currently two more ideal methods, one is to change human genes, so that human beings can adapt to various harsh environments, this is the best solution, and Zhang Wei put the hope of a breakthrough on the alien cell, because alien is a kind of space creature that can adapt to all kinds of harsh environments, from it should be able to find a way to adapt to various gravity environments; the other way is to modify the planet, so that the gravity of other planets is the same as the earth, such as a planet like Mars, you need to increase its mass, which is easier to do, only need to capture asteroids or comets and throw them on MarsThat's what Zhang Wei was going to do. And if neither of these options can be achieved, then humans will have to live in cities with artificial gravity. (To be continued.) )
