The vast galaxy flowed through the porthole, and in this vast universe, the divine consciousness could no longer compete with the line of sight. ｛｝

Without the obstruction of foreign objects, Zhang Binhui can see far away. Stars, planets, moons, comets, the stars in the solar system seem so close to themselves.

Mars is not visible to the naked eye, but Zhang Binhui can see Jupiter's shadow. Although Jupiter is farther away, as the largest planet in the solar system, its majestic body and beautiful rings are so eye-catching.

The two little girls sat quietly on the side, completely intimidated by the majesty of the universe, and could no longer pretend to be at home.

"We call that earthy yellow planet Jupiter, it is a liquid planet", pointing to Jupiter, Zhang Binhui took the initiative to introduce to the two girls:

"Jupiter is the fifth planet in the solar system from the inside out, and it is also the largest and fastest rotating planet in the solar system.

It has a mass of one-thousandth the mass of the Sun, but is 2 times the mass of the other seven planets in the Solar System combined. 5 times.

Jupiter has a large mass, so it has captured many moons, and as far as is known, Jupiter's moons have reached as many as 68. ”

"Its star rings are so beautiful! By the way, you say it's a liquid planet? ”

Ling Doudou looked out stupidly, asking questions unconsciously in her mouth.

"Yes, Jupiter is a huge liquid planet." -

One-book-read-small-say-

It is rare for a beautiful woman to ask, and Zhang Binhui answered very carefully:

"Jupiter is mainly composed of hydrogen and helium, and as the depth increases, the hydrogen gradually transitions to a liquid state.

At a distance of 10,000 kilometers from the cloud top of Jupiter's atmosphere, liquid hydrogen becomes liquid metallic hydrogen at high pressure and temperature.

It is speculated that Jupiter's center is a core region composed of materials such as silicates and iron, and the mass of the core is about 10 times the mass of the Earth.

There is no obvious boundary between the edge of the nuclear region and the outer material, and the composition and density of the material show a continuous transition. ”

"And where is our destination, why can't we see Mars yet?"

Zhang Binhui refers to Jupiter's rings:

"It should be in the upper half of this ring, right? Because of Jupiter's huge size in the background, and Mars is so small, we can't see it with our naked eyes.

According to my estimate, we will be able to see it tomorrow at noon when we are closer to it. ”

………

Back at Cape Canaveral, looking at the familiar center console, Jefferson and Parker were thrilled.

More than a month ago, the two were taken out of here and transferred to work in District 51, and since then they have embarked on completely different jobs.

Looking at this familiar environment and familiar colleagues, both of them were a little excited.

Colleagues were enthusiastic about their return, and Jimmy, the director of the base, accompanied the two to introduce the changes in the base during this time.

"You're here today just in time to activate Curiosity's on-board cameras, which will be Curiosity's last mission on Mars. Once this is done, we will launch the latest rover. ”

Jefferson and Parker smiled knowingly, they had applied for the trial, and they had come here today to get first-hand information.

The two men had orders from NASA headquarters in their hands, making Kennedy Space Center mistakenly believe that they had been transferred to headquarters.

The central control hall is very busy, and every staff member is nervously staying at their own work.

This test is important because once the onboard cameras are activated, Curiosity will end its mission to Mars, and NASA will remain on Mars without any active instruments for some time.

An order came from above: this experiment must only succeed, not fail.

The commander entered the first command, and the base's control tower sent radio waves into the starry sky, and the huge central screen in the central control hall opened.

"Successfully connected to the Curiosity rover, Curiosity awaits the next command."

The data on the screen is constantly appearing, and Curiosity is in very good shape.

"Turn on the car camera."

Jimmy gave the command, and the commander pressed it.

After a brief burst of snowflakes, a moving image appeared on the center screen, which was the live Mars captured by Curiosity.

There was thunderous applause in the hall.

At this time, the Curiosity was on the peak of Liming Mountain, which the command center had arranged for the Curiosity to climb two weeks ago.

Liming Peak is NASA's name for this crater, and standing on it, you can see Mars farther away. This position was also chosen so that the camera could be used to capture more things.

There is still a dead silence all around, there is no other debris on the screen, except for the Gobi on Mars, all that remains is yellow sand.

Jefferson and Parker sighed secretly: Could it be that their judgment was really wrong?

"Rotate 360 degrees to start framing from all angles."

………

The fiery red planet finally appeared in the porthole, and Zhang Binhui and the other three were finally able to look at Mars.

Hanging in the dark starry sky, Mars looks so beautiful. The destination is finally here.

Mars is much smaller than Earth's, and Ling Doudou gave the landing order to the spacecraft, which plunged into the Martian atmosphere.

A jolting sensation came from the ship, and red began to appear outside the porthole, the result of the ship's violent friction with the air.

The spacecraft began to automatically broadcast environmental explorations of Mars.

"Composition of the atmosphere: nitrogen, oxygen, carbon dioxide, water, methane, ammonia...... Surface temperature: 26 degrees Celsius. ”

Zhang Binhui was stunned for a moment: Hey, it's the same as the earth?

"Proportional composition of the atmosphere: nitrogen, seventy-one percent; Oxygen, 27 percent ......"

This result completely stunned Zhang Binhui, the composition ratio is basically the same as that of the earth, and the oxygen content of Mars is even higher than that of the earth!

What's going on? According to American research, isn't the Martian atmosphere mainly composed of carbon dioxide, nitrogen, argon, and very small amounts of oxygen and water vapor?

How is it that the realistic calculations are completely different from the knowledge of the earth? An environment like this should be very suitable for life.

As they approached the surface of Mars, the ship's descent slowed down, and the three men lay on the porthole, looking down with their heads sticking out.

The ground is still a patch of yellow sand, just like what I remembered. The mountains of Mars are much more majestic than those of Earth, and the spacecraft must find a relatively flat place to land.

A piece of flat land on the halfway slope of the mountain range was selected, and the spaceship landed on it very lightly, and with a "whew", the bulkhead opened a door, and a breath of fresh air blew in.

Mars has arrived.

The three men stepped out of the cabin, and a sense of relief came over them. The gravitational pull here is much smaller than that of Earth, giving the illusion of a wandering immortal.

There was no mistake in the test of the spaceship, Zhang Binhui carefully took a breath of air, and the feeling of comfort immediately spread throughout his body.

Fresh, refreshing, and unpolluted, the air here is even cleaner than the earth, and there is even a faint aura in it.

What's going on?
