Genius of the Rules-Style System

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

Internationally, other countries have launched Mars probes, and China has also relied on Z-wave satellites to take close-up photos of Mars. However, the camera functions of the satellites are limited. The photos transmitted are synthesized from data, and video images cannot be directly transmitted.

Now it's real video shooting and broadcasting, just like a live interview somewhere, which gives people a completely different feeling.

All the viewers in front of the TV felt a sense of shock, because what they saw was not the kind of composite photos or computer-generated videos, but the real appearance of Mars 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 also know that Mars is not suitable for human survival from the color.

What humans need is blue, the water is blue, the sky is blue.

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

Brown reminds people of vast areas of desolation.

Of course.

Mars is not suitable for human survival. It has not just been discovered. Many professional people are discussing live broadcast-related technologies.

This is a live video broadcast from around Mars. It uses space connection technology. But there is no doubt that it is impossible to transmit the video of Mars at a close distance just by relying on space connection technology. It is impossible to include the entire Mars.

Therefore, the technology used in the image must be a combination of original lens shooting and spatial linking technology.

Space link technology is only a technology for information transmission, while shooting mainly uses the original technology.

The current Mars-1 spacecraft can combine the two technologies and realize live transmission of external images, which shows that the domestic space link technology has been very mature and can no longer be said to be just a newly discovered technology.

This is also what makes many foreign information-related technology companies feel depressed. They have no space connection technology at all, let alone conduct research. There is no longer a gap between the two, but a huge gap.

Mars-1 spacecraft, inside the control module.

Several astronauts have regained their composure. No one among them is smiling. Even if they are thinking about what just happened, they can only hold back their emotions because they saw the link re-established, which means that many people are watching. The situation inside the cabin.

But even if they suppressed their laughter, they were very excited because they had arrived on Mars.

This is an amazing thing.

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

Now that I'm watching Mars up close, my inner feelings are completely different.

They still suppressed their excitement and began to get into work mode.

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

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

Simulation data is data calculated through simulated flight before the spacecraft sets off.

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

This is the most important task before landing on Mars.

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

In the control cabin, Zou Yongcheng is the captain and is also responsible for the main work.

Zhang Hongjuan is responsible for maintaining communication with the earth.

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

The other two people, like Zou Yongcheng, are responsible for data monitoring and part of the equipment control.

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

From this point on, it’s long hours of work.

According to the plan, the Mars-1 spacecraft will orbit Mars for thirty-seven hours, and then quickly fall towards the ground of Mars. The way of falling is similar to that of satellite recovery, that is, it will fall quickly towards the ground. When it reaches a certain height, the spacecraft will The anti-gravity system will be turned on, and the thrusters will be turned on to slow down and control, and then slowly descend to the ground.

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

The main purpose of choosing to land in a manner similar to that of recovering a satellite 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 spacecraft will be used for the next takeoff. Obviously, taking off consumes much more energy than landing, because gravity is counterproductive during the takeoff stage.

When the spacecraft continues to orbit Mars, the live broadcast will definitely not be able to continue. No live broadcast can last for dozens of hours, especially a live TV broadcast. In addition, the spacecraft also needs to save energy instead of spending it on On communication.

Soon, the live broadcast was interrupted.

The live TV station will occasionally broadcast the progress of the Mars mission, but will no longer broadcast the video footage. The next long live broadcast will be 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 it.

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

"Neither the astronauts nor the spacecraft suffered any impact, which shows 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 directly up there. All kinds of animals traveling through space will not be affected."

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

There is no doubt about this.

The Mars-1 spacecraft took off from the earth and relied on anti-gravity thrusters, while the spacecraft itself could only rely on the spacecraft itself to take off from Mars.

Analyzing it from an energy perspective, we know how big the gap is.

The launch of Mars relies on its own energy and solar power to supplement it. What is certain is that the solid fuel carried by such a large spacecraft is definitely not enough to supply the spacecraft to lift into 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 Earth's environment. Air resistance and air movement must also be considered.

First of all, during the landing process, the spacecraft will be affected by the Martian atmosphere, because when it is close to the Martian ground, the influence of the air will become very large, and it is impossible to unfold the dendritic compressed single crystal blades, so it can only pass through Consume 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 about to take off, it will definitely need to use space light energy transmission technology for a long time and continue to supplement it with solar energy to supply the anti-gravity system. At the same time, the spacecraft must also retain a part of solid fuel to support the high consumption of opening the space cover. .

etc.

After a series of calculations, the spacecraft can consume very limited solid materials during takeoff.

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

Zhao Yi explained, "Theoretically, it is possible to lift off the spacecraft only by relying on solar energy, but it will take a long time."

"The solar energy supply of the spacecraft can keep the anti-gravity system on and a small thruster operating at the same time."

"That small thruster is located directly under the spacecraft, and its thrust is very limited."

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

"This process will seem a bit slow. It can only go up about a thousand meters on the first day, and the speed will gradually increase later."

"And during the development process, we found that the difficulty is mainly focused on keeping the spacecraft balanced."

"Balance is a big issue."

"Conventional anti-gravity thrusters rely on jets in several peripheral directions to achieve the overall balance of the spacecraft."

"When the Mars-1 spacecraft takes off, it only relies on one thruster in the center, so it is not 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 network 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 maintaining balance."

"If there are special circumstances, such as a storm on the surface of Mars, or strong winds in one direction, the thruster on one side of the spacecraft with higher energy consumption will be turned on. When it is operating, it will always be in the opposite direction of the wind. direction."

This balanced design is definitely not as good as the intelligent control of several propellers operating together. The direct impact is that when encountering a less strong air flow, the control cabin will be like sitting on a rocking boat, swaying slowly from side to side. Slow upward, but the advantage is that without encountering strong air flow or harsh environments, the solar energy provided by space light energy transmission is enough to lift the spacecraft into space.

——

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

The live broadcast of Mars exploration has restarted. The hosts of various TV stations have been previewing it for more than half an hour. After waiting and waiting, the live broadcast screen was finally connected.

What appeared in front of the audience's field of vision was a dark yellow flat land. From a distance, it looked like endless desolation. The scene soon switched to a spacecraft landing on the surface of Mars, with an oblate object over one meter high placed next to it. , the round house is also carved with flag graphics.

That is the supply device that will be placed on Mars during the mission. It contains living supplies, oxygen production equipment and some electronic equipment.

Three astronauts are busy around the supply device. They need to unfold the fixed bracket that is smaller than the device, and then dig the front end of the fixed bracket into the soil so that the round supply device can withstand large storms without being destroyed. Blow dry.

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 them still holding a flag.

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

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

Then, it seemed to be 'free time'. Several astronauts were walking on the ground, and some were pointing and jumping. Unfortunately, they couldn't jump too high, mainly because the spacesuits were 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.

This gap coupled with the drag of the spacesuit means that astronauts cannot jump very high when jumping on Mars.

soon.

The astronauts got back to work, walking, looking, and grabbing at the Martian soil as they collected samples.

According to the established plan, they will collect ten soil samples and place the samples in the designed groove at the end of the robotic arm extended by the spacecraft.

The work of collecting soil samples takes about ten minutes.

The farthest distance the astronauts have traveled is only about a hundred meters away from the spacecraft. Any further distance may be risky.

At the same time, they also need to constantly pay attention to detection data to predict possible coming storms.

This is the most dangerous place on the surface of Mars.

If a storm suddenly hits, they must return to the spacecraft as soon as possible and close all the hatches to ensure safe passage.

After the robotic arm collects the collected samples into the spacecraft, the astronauts' work is almost over, and the next step is to control the spacecraft to perform the task.

For example, a Mars rover was placed.

This Mars exploration rover is specially manufactured and weighs about 800 kilograms. The light energy receiving converter takes up the most weight, and the other is the space transmission equipment.

The rover is an 'infinite power car' and can also be easily controlled through space transmission equipment. As long as it does not encounter a very harsh environment that causes damage to the link system and energy system of the rover, the rover can continue to operate and can Pass the news to the NASA operations room in a timely manner.

After the Mars-1 spacecraft released the rover, the host kept introducing the rover, and at the same time, everyone in front of the TV was amazed by the powerful performance of the rover.

Timely control of the earth, timely transmission of information, unlimited power——

It is simply a rover that can only exist in imagination, but it has actually appeared and been placed on the surface of Mars!
