The astronauts started working again. They walked around, looked at, and grabbed the Martian soil with their hands. They were collecting samples.

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

The work of collecting soil samples took about ten minutes.

The farthest distance the astronauts have traveled is only about 100 meters away from the spacecraft, and there may be risks if it is farther away.

At the same time, they also need to constantly pay attention to the detection data to prevent the possible storm attack.

This is the most dangerous surface of Mars.

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

When the robotic arm collects the collected samples into the spacecraft, the work of the astronauts is almost over, and the next step is to control the spacecraft to perform tasks.

For example, a Mars Exploration Rover was placed.

This Mars Exploration Rover was specially manufactured and weighed about [-] kilograms. The light energy receiving converter and the space transmission equipment accounted for the most weight.

The probe car is an "unlimited power car", and it can also be easily controlled through the space transmission equipment. As long as it does not encounter a very harsh environment, causing damage to the link system and energy system of the probe car, the probe car can continue to operate, and it can also Timely pass the news to the space agency's operation room.

After the Mars-1 spacecraft released the rover, the host continued to introduce the rover, and at the same time let everyone in front of the TV marvel at the powerful performance of the rover.

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

It's like a rover that can only exist in imagination, but it actually appeared and placed on the surface of Mars!

Chapter 6 The most tense moment

The whole world was shocked by the powerful performance of the Yixing H-1 Mars rover released by the Hwasong-1 spacecraft.

The international aerospace field has been continuously launching Mars probes to detect the situation on the surface of Mars. The Mars probes launched in the past are mainly affected by energy and information transmission.

One aspect is energy.

If traditional battery technology is used, the Mars rover will be affected by the battery power and cannot work for too long at all.

Later, with the development of solar energy technology, Mars rovers generally operate in solar charging mode, but because of the atmosphere on Mars, solar panels will be affected by the seasonal changes on Mars. Even in the season when the sun is abundant, the Mars rovers will Insufficient power supply occurs.

Two years ago, the Mars probe launched by country M adopted a more advanced nuclear energy mode, but because of the limited quality of the probe, it could only use the simplest nuclear energy mode. The power of nuclear energy into electrical energy is not even comparable to solar charging technology, but it is more stable and has a longer service life.

In addition, detectors always have the effect of information transmission. .

Frequency signals are not omnipotent.

The farthest distance between Mars and the earth can even exceed [-] million kilometers. Even electromagnetic waves need to be transmitted for [-] seconds. In addition to information conversion and command interpretation, the time consumed is a bit long.

Several probes launched to Mars lost their link with the earth's surface before the end of their energy life. The main reason was that they failed to operate in time, which caused the Mars probes to fall into a dangerous environment.

The above two points are the key to restricting the operation of the Mars rover.

Yixing-H1 solves the problem of energy and information transmission. The energy is using solar energy transmission technology. The single crystal fan blade at the tail can provide continuous solar power supply. Information transmission and operation are all using space connection technology, which can achieve Timely operation without delay.

The combination of the two technologies, at least in theory, can keep working without encountering uncontrollable dangers.

While the international public opinion was constantly discussing, the astronauts had finished their work, completed the task and returned to the spacecraft.

The hosts of various TV stations also began to introduce the method of the Mars-1 spacecraft returning to the earth, "The Mars-1 spacecraft mainly relies on the transmission of solar energy and the solid fuel loaded to get rid of the gravity of Mars, and then rely on the Z orbiting Mars. wave satellites, and establish a space shuttle route to return."

"A lot of cutting-edge technology was used in the whole process."

Although the TV host just gave a brief introduction, it still gave people a very shocking feeling. The technical difficulty of launching from the earth and launching from Mars is not a concept at all.

Regardless of whether the returned mission can be successful, as long as there is technology to do it in theory, it is already quite remarkable.

For human exploration of the starry sky, Mars exploration is a history full of failures.

Among them, the E space agency is the most failed one. They started Mars exploration more than 50 years ago, and carried out more than 20 related missions, but very few of them succeeded.

In the 60s of the last century, that is, in 1960, the former E country started the Mars exploration mission, and they launched a Mars probe to Mars.

This launch mission was a success, and it is also an extremely rare success experience in the history of country E's exploration of Mars.

Two years later, the former E country launched the Mars 1 probe. When it was 1962 million kilometers away from the earth, the probe lost connection with the ground. Since then, there has been no news. During the same period, the other Mars 1962A and Mars [-]B probes started , also announced that the launch failed one after another.

Another two years later, the former E launched the probe again, and it failed again. Although the probe successfully reached the vicinity of Mars, it did not send any data back to the earth because the solar panels were damaged.

The unremitting spirit of the former E space agency is worthy of recognition. It can be said that they have been defeated repeatedly, and they launched a probe again after a year, but the result still ended in failure.

The consecutive failures did not dampen the confidence of the former E-country space agency. Four years later, they continued to launch probes, and launched two probes in one breath. One of them exploded due to engine failure 7 minutes after launch, and the other It fell to the ground less than a minute after launch.

More than a year later, they continued to launch, and launched three in one breath. The first probe made a mistake after launching into space. Later, for unknown reasons, the former E country did not admit the launch, and the second probe successfully arrived at Mars. The surface became the first man-made object ever to reach the surface of Mars, but because it quickly encountered a sandstorm, it lost its connection before it landed. As soon as the third probe successfully landed on Mars, it encountered the same sandstorm. Lost connection after only working for 20 seconds.

Afterwards, the former country E launched Mars [-] to [-] consecutively, and launched four probes directly as if by luck. Among them, No. [-] successfully sent back [-] images to the earth. The mission stopped working after nine days, and other probes All planes failed to land.

Later, the former E country carried out several Mars exploration missions, some of which had problems after the launch, and some of them lost their communication connection with the earth after entering Mars orbit.

and many more.

Seven years ago, country E restarted the mission to Mars. The probe machine was equipped with a domestically developed Mars probe. As a result, the orbit change failed because the active propulsion device failed to ignite.

no doubt.

The exploration of Mars by the E-country space agency is a history of continuous failures. There are also very few successes, but it still cannot cover up a large number of failures. Of course, it cannot be denied. Spirit.

Internationally speaking, country M's exploration of Mars has been relatively successful, but success is only relative. Half of their exploration activities ended in failure.

Half of the tasks can be successful, which is already very remarkable.

Most of the current international information about Mars is the success of the US space agency, including photos of the Martian surface, atmospheric analysis, soil conditions, and so on.

Now, for the first time in China, the mission related to the surface of Mars has been carried out, and the manned landing has been completed directly, and the ultra-high-performance Mars probe has been released. The mission has brought back a large amount of data so far.

This can be said to be a great success in the history of human exploration of Mars.

After the live broadcast of the mission ended, the international discussion still did not stop, but it became more and more heated. With this, Yixing Company's international reputation has greatly increased, and a large number of media reports are inseparable from the "domestic space agency" and "domestic space agency". Yixing' and other vocabulary.

This also allowed Yixing Company's reputation to directly overtake Space Exploration Technology Corporation, becoming the most famous and considered the most powerful private space exploration company.

There are discussions and shocks everywhere.

The focus of public opinion mainly revolves around 'five astronauts landed on Mars', 'the performance of the Yixing-H1 probe', 'the spacecraft release supply device', etc. In addition, many people are also concerned about whether the Mars-1 spacecraft can return successfully Earth.

If the Mars-1 spacecraft can successfully return to Earth, the Mars exploration mission can be said to be perfect.

Whether the Mars-1 spacecraft can successfully return to the earth is actually very meaningful, which marks that human beings have the ability to travel to and from ultra-long-distance planets.

This is mainly because of the technology used by the Hwasong-1 spacecraft.

First, there's the space shuttle.

The Mars-1 spacecraft can quickly reach Mars, which is nearly [-] million kilometers away, and then it can reach farther planets. The distance between planets can be said to be no longer a problem.

In addition, it is the technology of launching from Mars, using space solar energy transmission and anti-gravity technology, even if the planet is far away, when the energy source is not limited, everything is not a problem, and the anti-gravity technology will not be affected by gravity. What a difference.

In other words, a spaceship launched using anti-gravity technology, whether it is on Mars or on Earth, has similar technology, and there is not even much difference in energy consumption.

This is an extremely important technological leap for human beings to explore space and explore other planets.

That's right, it's the jump.

There are also precedents of landing on other planets before, just like the Apollo landing on the moon, the astronauts successfully returned to the earth, but taking off from Mars and taking off from the moon are completely two concepts.

One is that the moon is very close, 38 kilometers away from the earth, and it can even be said to be 'close in sight'.

Another very important point is that the moon has very little gravity and no atmosphere.

The latter is critical.

During the take-off and landing process of a planet, the influence of the atmosphere is very large. The atmosphere will affect the landing and the lift-off.

The technical difficulty of Mars launch and moon launch is completely different.

Space agency.

The live TV broadcast has ended, but the Mars exploration mission is not over yet, and it has reached the most critical time.

As it is discussed internationally, returning to Earth from Mars is much more difficult than going from Earth to Mars.

In this exploration mission, return is the key.

There are many cases of failure of Mars exploration in the world. The Mars exploration mission jointly conducted by Yixing and the space agency uses the latest technology, but many people do not know it.

The senior leaders were very nervous, and he kept asking technical questions, hoping to know more about the return process.

Fortunately, the communication is still maintained.

Although the large-scale space transmission link was disconnected, the Mars-1 spacecraft would link with the ground every half an hour to report safety and mission progress in time.

In fact, Zhao Yi was also a little worried about the return of the spacecraft. While he kept emphasizing the ineffectiveness of technology and equipment, he also used the "Law of Karma" twice to judge the situation of the Mars-1 spacecraft.

The Mars-1 spacecraft was not in front of him, and judging the situation of the spacecraft was a high-consuming problem. He could only make judgments by replenishing learning coins continuously, and the returned answer was reassuring.

This is the best news.

Now that the Hwasong-1 spacecraft is slowly rising into the sky, it is necessary to reduce energy consumption. The ground can only maintain the link while waiting for the progress of the mission, and nothing else can be done.

In the command room of the space agency, many people closed their eyes and prayed silently. They hoped that the prayer would play a role and the spacecraft could return safely.

At this time, the control room of the Hwasong-1 spacecraft.

Lu Xiaowei, Zou Yongcheng and the others also felt nervous. Sitting in the spaceship, all they needed to do was stare at the data to prevent bad weather or other emergencies.

In the absence of similar situations, all they can do is wait.

The astronauts were more disturbed than others, because they were direct participants. Only Zou Yongcheng and Lu Xiaowei participated in the spaceship test.

That time was the launch experiment of the spacecraft, and it only rose to [-] kilometers from the surface of the earth. The gravity and air data of Mars are different from those of the earth, so there must be some differences.

For example, for Mars, if it rises above [-] kilometers, it has almost reached "space", while the earth's definition of space is [-] kilometers from the ground.

The Hwasong-1 spacecraft is slowly ascending into the sky. The route to the sky is straight. When it is close to the surface, due to the influence of air resistance, it cannot accelerate laterally. The spacecraft is equipped with an air density detector, which shows that the air density When the density is lower than a certain value, the impact on the spaceship is very small, and it can accelerate laterally.

The way to accelerate the spacecraft is very simple, that is, to tilt the central propeller, and the spacecraft will also tilt accordingly, so that it will slowly accelerate in one direction during the process of continuing to lift off, and then the spacecraft will become higher and higher. quick.

The calculation data of the mission is that the spacecraft will be able to accelerate to escape the gravity of Mars after half a circle around Mars.

After breaking away from the gravity of Mars, the spacecraft continues to circle Mars for about four times, and then it can use the transmitted solar energy to fully charge the battery, and then use the remaining solid fuel, solar energy, and battery energy to propel and open the space cover together, and enter the Z-wave satellite. The released space shuttle returns to Earth.

The launch speed of the spacecraft was slower than expected. It took seven days for the ground to receive the news from the spacecraft. They were already 35 kilometers away from the surface of Mars. The detection data was all safe and they could start to accelerate.

The message passed by the command on the ground was, "Everything, you judge for yourself."

"Everyone believes in you!"

These are words of encouragement.

In fact, at this time, several astronauts were very nervous, because the acceleration of the spacecraft is not a simple control, and the tilt of the spacecraft is likely to cause problems, and there is even the possibility of a direct crash.

As the team leader, Zou Yongcheng felt very nervous, his cheeks were covered with sweat, his expression was very solemn, and he said to the others, "It's now!"

The others nodded firmly.

Lu Xiaowei said, "Captain, you decide!"

Others followed suit, "We believe in you, captain!"

"Captain, it's all right!"

"Everything is as planned, the spaceship took off a bit slower, but it's within the normal range, no problem!"

Several people simply held hands as they spoke, encouraging each other in this way.

Zou Yongcheng took a deep breath, looked down at the operating lever, then raised his head to look at the others, then took another deep breath, closed his eyes and pulled up the operating lever forcefully.

"boom!"

The spaceship shook suddenly, and quickly tilted to one side.

Lin Sheng's screams could be heard from the control room, and the others were also very nervous, and they all grabbed the safety handrail with all their might.

They felt that the spaceship sank suddenly, as if it had fallen. Fortunately, after a pause, the spaceship tilted a little and became stable again.

"call--"

Everyone became calmer, and after staring at the test data, they all felt that they had regained their lives.

"no problem!"

"It's safe! It's a success!"

"Haha, I just said it's okay!"

"Who shouted that just now? It scared me!" Suddenly, several people looked at Lin Sheng.
