Chapter 181 A Plain Journey to Mars (please subscribe, thank you)

The rocket was ready. A group of people sat in front of the computer, looking at the data in front of them, and calmly analyzing. This time, it was different from before.

The satellite that was sent up last time was an automatic flight, but it failed, and it disappeared before it got there.

This time, it was people going up.

Wang Hu and another girl looked at Chen Fan calmly.

"If something goes wrong, let yourself calm down for the first time, remember that you must enter the sleep stage."

"good."

"You are asleep, and Xiaomei is controlling, you still have a little chance of surviving."

"Understood, Chen Fan, thank you."

"I hate it the most. I really hate it. I don't like this project. It puts the danger of people in my hands."

Watching two people get on the rocket.

Everything is ready.

When the rocket ignited, no one dared to gasp.

There is no live broadcast either.

The rocket lifted off smoothly.

On the first night, I reached the moon and could go down, but it was stopped.

The next night, it was still on the way 03.

At this time, the signal appeared once and disappeared briefly, and then reconnected.

On the morning of the third day, people began to popularize science on major live broadcast platforms.

"Mars is one of the eight planets in the solar system. It is ranked fourth in the order of distance from the sun. This red planet has attracted people on Earth since ancient times. The ancient Romans used it as the god of farming. The Greeks who were prone to aggression and expansion took it as a symbol of war and called it the god of war, Mars. In ancient my country, it was called "Linghuan", which means "fluorescent fire, Lili chaos and confusion." Because its brightness often changes. , And moving in the sky, sometimes from west to east, sometimes from east to west, the situation is complicated and confusing.

After years of observation and research, we have learned that this "neighbor" is the fourth planet in the solar system from the inside to the outside. It belongs to the terrestrial planet, with a diameter of half the earth, and the rotation axis inclination and rotation period are similar. Times the time. The orange-red appearance is due to the hematite (iron oxide) on the surface. Mars is basically a desert planet with sand dunes and gravels all over the surface, and there is no stable liquid water body. The carbon dioxide-based atmosphere is thin and cold, with sand and dust suspended in it, and dust storms often occur every year. Both poles of Mars have polar caps composed of water ice and dry ice, which will increase and decrease with the seasons. "

Everyone has a question mark on their faces.

At 7 o'clock in the evening, the news broadcast gave a live broadcast for a period of time.

Yes, the news network gave a live broadcast.

The live broadcast shows Wang Hu holding a video camera.

"Hello everyone, we have entered Mars, and we are now preparing to investigate data and prepare to land."

? ? ? ?

The question mark on everyone's face made them dumbfounded.

what's that?

You say it again?

Damn it, is this going to Mars?

Are you kidding me internationally?

Under everyone's attention, Wang Hu put on his armor and slowly opened the hatch.

Following everyone's attention, Chen Fan guessed on the ground.

There is no external shooting, and there are not so many things, just a footprint, and then the road is on the ground.

Then Xiaomei turned on some shooting devices on the rocket. Here, Wang and Hu were seen by everyone from the third perspective.

"Fuck, is this Mars?"

Looking around, barren, barren, maybe, this is what everyone thinks.

The gray sky.

Yes, Mars has a sky, this is, the atmosphere is very tin foil.

"Preparing to start the experiment. We are calculating the gravity of Mars and preparing to sample."

In an unknown corner, a robot ran off the rocket, and then got into the ground. Chen Fan asked Xiaomei to control and arrange this.

With everyone's perspective, Wang Hu moved on the ground little by little.

Collect samples, to follow-up experiments and so on.

The time is short, and we need to return soon.

And Chen Fan's hanging heart at this moment finally let go.

There are special professors to deal with matters concerning the interpretation of Mars.

"First, the Mars rover needs to prepare a long-distance, long-life carrier when launching, and the carrier needs to have the ability to adapt to long-distance and normal operation in a complex space environment; secondly, the rover’s orbital design is complex, and the China-Russia joint Mars Take detection as an example. The launch vehicle transports the probe to the parked circular orbit, and then the probe runs in the parked orbit for more than 2 laps, that is, about 174 minutes from the launch time, the upper stage engine is propelled to ignite once, and the probe is transferred. It is on a transition orbit with an orbital period of 2.6 hours to apogee of 6000 kilometers.

After flying a circle on the transition orbit, about 5.5 hours from the launch time, the propulsion of the upper stage engine was started for the second time. The probe enters a hyperbolic orbit away from the earth, which changes into an earth-fire interplanetary orbit after leaving the earth's affected zone (1 million kilometers, 3.3 day and night flight). The probe completed three orbit corrections during the transfer flight. The first orbit correction is 5-10 days and nights after the flight. The second orbit correction was completed in the middle of the orbit. The third orbit correction will proceed in 4 to 2 weeks after reaching Mars. After the orbit correction, the probe flew to Mars along a hyperbolic orbit, which shows that the orbit design and correction process of the probe is complicated when it is on fire. "

Facing the inquiry, the official gave a very vague answer.

But in the ears of foreigners, this f*ck is just making an international joke, because it was the most rubbish design ten years ago.

The current design has already surpassed these.

It's too bad, don't you talk about it?

Chen Fan yawned and said, "Well, if there is nothing wrong, I will go to bed."

Everyone looked at Chen Fan, and for a while, they didn't know whether to celebrate or to be sad.

Tao Yaoyao said, "Everyone will celebrate later. By the way, when Wang Hu returns, we have to pay attention."

Everyone nodded one after another.

Chen Fan returned to the house and picked up the phone.

"Well, it's almost finished, there is no problem with fuel, and for the follow-up things about the return journey, just follow the route you went before."

"Well, Chen Fan, what do you need?"

"It's nothing, just let people go home,"

"Just this one request?"

"Yes, just this one request."
