"Roger that!"

"Report, everything is normal!"

"Prepare!"

"Countdown—!"

Following the instructions one by one, the Mars-1 spacecraft opened the space cover, and at the exact time, entered the space shuttle channel, and quickly disappeared from view.

At this time, a scream came from the control cabin of the spacecraft, "Ah—"

Several astronauts all looked at the location of the sound.

It's Lin Sheng.

It was the first time for Lin Sheng to experience the space cover. He thought it was no big deal before, but when he was really in a dark space, his heart was suddenly filled with fear.

The darkness inside the space cover is not at the same level as the darkness of night.

The former really has no light, and even a little bit of light will be absorbed. Coupled with the influence of the shuttle channel, the interior of the spacecraft is far from being invisible, and it really feels like vision disappears.

In contrast, the night is much more comfortable, at least there is a little light.

Lin Sheng is an engineer who has only received short training, and his mental quality is relatively poor. He is suddenly in a completely closed and dark environment, and almost collapses directly.

Fortunately, time is short.

Seven seconds later, the spacecraft completed the space shuttle and appeared on the edge of Mars.

After 20 seconds, the space cover was closed and everything returned to normal.

The light in the control room was turned on again, not a very bright light, and even made several astronauts feel very dazzling.

Lin Sheng finally got rid of his fear, looked around blankly, with tears in the corners of his eyes, and found that several people were looking at him.

At this embarrassing moment, Zou Yongcheng said, "Fortunately!"

"What?" Lu Xiaowei asked.

"Fortunately, we are all wearing spacesuits, otherwise we would not be able to stay in this place!" Zou Yongcheng said and took a deep breath through his nose.

This action made everyone understand what he meant, and there was a burst of laughter in the cabin.

Lin Sheng's face was flushed with embarrassment, and the most embarrassing thing was that he couldn't help laughing, and at the same time, he also paid attention to the feeling below.

No!

Ok!

"Look!" Zhang Liping exclaimed suddenly, pointing to the glass partition.

Several people looked at the past together.

A huge star appeared outside the glass compartment. It was light brown overall, with white as if it were decorated with clouds, showing a unique beauty at close range.

"That's Mars!"

"It's Mars, yes! We're on Mars!"

"It's here! It's really fast!"

"Ten seconds!"

At the same time, the live TV also used space information transmission technology to show close-up pictures of Mars, which aroused a lot of discussion.

Chapter 659 Unlimited Power Mars Exploration Rover

This is the first time humans have taken a close-up video of Mars.

There are other countries in the world that have launched Mars probes, and China has also relied on Z-wave satellites to take close-up photos of Mars. However, the satellite’s camera function is limited, and the photos transmitted are all synthesized from data, and video images cannot be directly transmitted.

Now it is a real video shooting and broadcasting, just like doing a live interview somewhere, which brings a completely different sense to people.

All the viewers in front of the TV felt a sense of shock, because what they saw was not the kind of composite photos, nor the video produced by the computer, but the appearance of Mars that they really saw up close.

The light brown enlarged planet, coupled with the embellishment of white lines, brings another kind of beauty to people. At the same time, many people know that Mars is not suitable for human survival from the color.

What human beings need is blue, water is blue, sky is blue.

On land, large green plants are needed for human survival, and the main color of Mars is light brown.

Brown makes people imagine a large area of ​​desolation.

Of course.

Mars is not suitable for human survival, but it is not just discovered. Many professional people are discussing live broadcast related technologies.

This is a live video broadcast from around Mars, using space connection technology, but there is no doubt that it is impossible to transmit the video of Mars at close range with only space connection technology, because space connection technology It is impossible to contain the whole of Mars.

Therefore, the technology used in the video must be a combination of the original lens shooting and space link technology.

The space link technology is only a technology for information transmission, and the shooting mainly uses the original technology.

The current Mars-1 spacecraft is able to combine the two technologies and realize the live transmission of external images, which shows that the domestic space link technology is very mature and cannot be said to be just a newly discovered technology.

This is also what makes many foreign information-related technology companies feel depressed. They do not have spatial connection technology at all, let alone conduct research. There is no longer a gap between the two, but a huge gap.

Hwasong-1 spacecraft, inside the control cabin.

Several astronauts have regained their composure, and none of them are laughing. Even thinking about what happened just now, they can only hold back their emotions, because they saw the link re-established, that is to say, there are many people watching The situation in the cabin.

But even though they were holding back their laughter, they were very excited because they had reached Mars.

This is a great thing.

They became the first team to reach Mars, and they will soon be the first to land on Mars, and their moods are filled with pride and glory.

Looking at Mars at close range now, the inner feelings are completely different.

They still suppressed their excitement and started to work.

As the captain, Zou Yongcheng began to explain his work. He is the commander in the control cabin, responsible for the overall situation of the work, and monitoring the operation of the spacecraft. Monitoring the operation of the spacecraft is very important, and many data require careful attention.

The data monitoring of the spacecraft is mainly to compare the existing flight status and real-time data, including the distance to Mars, the speed and direction of the spacecraft, and the energy status, etc., with the simulated data of the system.

Simulation data, that is, data calculated through simulated flight before the spacecraft departs.

According to the data calculated by the simulated flight, the spacecraft can land on Mars extremely accurately. The real-time status of the spacecraft should not be too different from the simulated data. If there is a gap exceeding the critical line, the astronauts must manually control the spacecraft and try to get the data back. within the range of deviation from the simulated data.

This is the most important work before landing on Mars.

Of course, there is another situation where the deviation between the two data is too large, and it is necessary to keep in touch with the ground to immediately formulate a new landing plan, or completely change the service plan.

In the control cabin, Zou Yongcheng is the team leader and is also responsible for the main tasks.

Zhang Hongjuan is in charge of maintaining communication with Earth.

Lin Sheng is responsible for the monitoring of equipment data to ensure the normal operation of every part of the spacecraft. If there is an abnormality, it needs to be repaired immediately.

The other two, like Zou Yongcheng, are responsible for data monitoring and some equipment control.

Every astronaut has work to do, most of which are monitoring and communication, but they must concentrate on doing it well without any mistakes.

From then on, it was long hours of work.

According to the plan, the Mars-1 spacecraft will orbit Mars for 37 hours, and then quickly fall towards the ground of Mars. The way of falling is similar to that of satellite recovery, that is, it falls towards the ground quickly. When it reaches a certain height, the spacecraft will open. Anti-gravity system, and turn on the propeller to slow down, control, and then slowly land on the ground.

The entire landing process mainly relies on the gravity of Mars.

The main purpose of choosing to land in a similar way to recovering satellites is to save energy. The direct landing method is definitely safer, but it consumes a lot of energy.

Now most of the remaining energy of the spaceship will be used for the next take-off. Obviously, take-off consumes much more energy than landing, because the gravitational force is counterproductive during the take-off stage.

When the spacecraft keeps orbiting Mars, the live broadcast will definitely not be able to continue. It is impossible for any live broadcast to last for dozens of hours, especially TV live broadcast is even more impossible. In addition, the spacecraft also needs to save energy instead of spending energy on communication.

Soon, the live broadcast was interrupted.

The live TV station will occasionally broadcast the progress of the Mars mission, but will not broadcast live video footage, and the next long-term live broadcast will be carried out after the spacecraft lands on the surface of Mars.

When the live broadcast of the Mars mission was interrupted, public opinion around the world was still discussing.

"The Mars exploration mission is really amazing. It reached Mars in a dozen seconds. The space shuttle must have been a success."

"Neither the astronauts nor the spacecraft were affected in any way, indicating that space shuttle is harmless to the human body."

"This has been tested a long time ago, otherwise it would be impossible to send people up directly, and all kinds of animals will not be affected by space shuttle."

"I don't know if I can return safely. Compared with going to Mars, returning is more difficult."

There is no doubt about this.

The Hwasong-1 spacecraft lifted off from the earth, relying on the anti-gravity propulsion to carry it, while the launch from Mars can only rely on the spacecraft itself.

From the perspective of energy, we know how big the gap is.

The launch of Mars is supplemented by its own energy and solar power. It is certain that the solid fuel carried by such a large spacecraft is definitely not enough to supply the spacecraft to ascend to space.

Then the supplement of solar energy is very important.

But even the solar energy provided by space light energy transmission technology is definitely not as good as the explosive solid fuel energy.

Mars has an atmosphere, which is similar to the environment on Earth. Air resistance and air movement must also be considered.

First of all, during the landing process, the spacecraft will be affected by the atmosphere of Mars, because when it is close to the ground of Mars, the influence of the air will become very large, and it is impossible to expand the dendritic compressed single crystal blades at all, so it can only pass The method of consuming solid fuel to operate the thrusters.

This process requires the consumption of a portion of solid fuel.

So how much solid fuel is left?

When the spacecraft is going to take off, it will definitely need to use space light energy transmission technology for a long time, and continue to use solar energy as a supplement to supply the anti-gravity system. At the same time, the spacecraft must also reserve a part of solid fuel to support the high consumption of opening the space cover. .

and many more.

All in all, during the take-off process of the spacecraft, the solid materials that can be consumed are extremely limited.

After the first phase of work was over, and the space agency was also working hard internally, the senior leaders asked about the return energy.

Zhao Yi explained, "Theoretically, relying solely on solar power can also lift the spacecraft into space, but it will take a long time."

"The spacecraft's solar energy supply can keep the anti-gravity system turned on while maintaining a small thruster operation."

"The small propeller is directly under the spacecraft, and the thrust is very limited."

"So the upward power of the spacecraft depends on the thrust of the upward air."

"This process will seem a little slow. On the first day, it can only go up about 1000 meters, and the subsequent speed will gradually increase."

"In the process of research and development, we found that the difficulty mainly focused on keeping the spacecraft in balance."

"Balance is a big issue."

"The conventional anti-gravity thrusters rely on the injection ports in several directions around the periphery to achieve the overall balance of the spacecraft."

"The Hwasong-1 spacecraft, during the take-off process, only relies on one propeller in the center, so it is not so easy to maintain balance."

"We rely on a newly developed intelligent sensing system and the retraction function of the balance net above the thruster."

"After the balance net contraction function is turned on, the nozzle of the ultra-small thruster will always operate in the direction of the source of gravity."

"That's the key to keeping the balance."

"If under special circumstances, for example, there is a storm on the surface of Mars, or there is a strong wind in one direction, the propeller with higher energy consumption on one side of the spacecraft will be turned on. When it is in operation, it will always be in the opposite direction of the wind. direction."

This balance design is definitely not as good as the intelligent control of several propellers working together. The direct impact is that when encountering a less strong air flow, the control cabin will shake slowly from side to side like sitting on a shaking boat. Slow upward, but the advantage is that, without encountering strong air flow or harsh environment, the solar energy provided by space light energy transmission is enough to make the spacecraft ascend into space.

-

Two days later, at three o'clock in the morning capital time.

The live broadcast of Mars exploration restarted, and the hosts of various TV stations had announced the announcement for more than half an hour. After waiting and waiting, the live broadcast screen was finally connected.

What appeared in front of the audience was a dark yellow flat land, which looked like endless desolation from a distance. The scene quickly turned to the spacecraft that landed on the surface of Mars, and beside it was an oblate object more than one meter high , The circular house is also engraved with the graphics of the flag.

That is the supply device to be placed on Mars during the mission, which contains living materials, oxygen generating equipment and some electronic equipment.

The three astronauts are busy around the supply device. They need to unfold the fixed bracket that is not enough to reach the device, and then plunge the front end of the fixed bracket into the soil so that the circular supply device can withstand large storms without being damaged. Hair.

After half an hour of busy work, the work of fixing the supply device was completed. One astronaut returned to the spacecraft, and soon two more came out, one of whom was still holding a flag.

The flag was inserted next to the semicircular supply device, and several astronauts stood together and took pictures with the flag.

This moment is very memorable, marking the team representing the country, officially landed on Mars, and planted the national flag.

Afterwards, it seemed to enter the 'free time'. Several astronauts were walking on the ground, and some were jumping and jumping. Unfortunately, they couldn't jump too high, mainly because the space suit was too heavy. In addition, The gravity of Mars is not low, and the gravity of the earth is only 2.67 times that of Mars.

Coupled with this gap and the drag of the space suit, the astronauts cannot jump very high when jumping on Mars.

soon.
