Each of the current circum-solar concentrating satellites can transmit more than 30 kilowatts of light energy power, and only three satellites can provide a power of one million kilowatts. The cost of manufacturing and launching the satellite is about 70 billion yuan, and the follow-up will soon It will soon drop to 60 billion yuan.

A large-scale light receiving device can receive up to 1000 watts of power, and [-] units are needed for a million kilowatts. The manufacturing cost of each unit is about [-] million yuan, and [-] units is about [-] million yuan.

The cost of compressing single crystal silicon wafers is relatively expensive, but it can roughly accept tens of millions of power, and it is enough to drop three billion.

Adding all the items together carefully, using the light energy receiving and converting device to produce millions of kilowatts of power, the cost is only more than 100 billion yuan, and at most it will not exceed half of the nuclear fusion device.

Of course.

There is also a very bad thing about using light energy reception and conversion technology as an energy source, that is, the total weight of the device must be much higher than that of nuclear fusion devices.

"About twenty times? Almost—" Zhao Yi calculated carefully and came up with an estimated number.

Light energy receiving conversion technology requires a large amount of compressed single crystal silicon.

This material itself is very heavy, and the combined weight of a large amount far exceeds that of a nuclear fusion device.

If it is used on the earth, it is of course no problem to be heavier, but it is used to build a base on the moon, and it means that the required "transportation expenses" will be greatly increased.

Fortunately, the increased cost is acceptable compared to the cost of 'tens of billions' units.

Of course, the premise of everything is that a large amount of equipment and materials can be transported to the surface of the moon, and personnel can go to the surface of the moon to start work.

This will be a large and continuous project that will definitely require a lot of manpower.

Lots of astronauts?

Of course not.

"If you want to build a base on the surface of the moon, you must first build a place for personnel activities, and you need a large pressure-resistant device, just like a big house, to cover everything."

"In this way, the staff can move freely inside, instead of just staying on the moon in spacesuits."

Spacesuits can certainly resist the harsh environment of the moon, but it is impossible for normal people to work in spacesuits all the time. It is acceptable for a short period of time, but it is impossible for a long period of time.

Therefore, the large anti-pressure cabin similar to a house, that is, the area where humans can live normally, is the most critical.

"Then R&D has two directions—"

"One is to find the right main material to make a large pressure chamber."

"In addition, it is to create a spaceship with a transportation function, which can continuously deliver materials to the moon."

Zhao Yi made a decision and wrote a special report. When he was ready to go back, he held a company meeting to make a decision. At the same time, he also found an opportunity to communicate with the senior leaders.

When the senior leaders heard his plan, they opened their mouths in surprise, not knowing what to say for a long time.

Build a moon base?

Are you ready to start the era of space colonization before the Mars exploration mission is over?

The senior leader feels a little behind the train of thought, but what else can he say?

of course not.

Yixing Company is a normal operating company, and at the same time they are also a normal state-owned holding company. Every mission of space exploration also cooperates with the space agency.

Therefore, Yixing's space exploration plan can also be regarded as a domestic work. All technologies and mission processes are fully disclosed to high-level officials. The difference is that Yixing is a market operation mechanism.

This also has great benefits.

Companies with a market operation mechanism all pay for their own projects, and they can complete difficult space missions without paying a penny in China.

If you take the space agency as a comparison, every mission of the space agency requires a high expenditure, and all taxpayers' money is used.

One is that there is no need to spend money at all, and a certain amount of tax can be charged.

The other one spent a lot of money and didn't make any profit at all.

Choose between the two with your eyes closed, and you all know how to choose. Because of this, Yixing's space exploration plan will not be subject to any restrictions, and will even receive absolute support.

Now that Zhao Yi is talking about the "Moon Base" plan, it means that Yixing will concentrate on the "Moon Base" project in the next step.

In this regard, of course it is supported!

At that time, there may be an extra piece of land in the country?Right on the moon!

"Does this count as expanding the territory?" The senior leaders thought carefully and began to look forward to it.

at the same time.

The Hwasong-1 spacecraft is still orbiting Mars, and will soon enter the Z-wave satellite channel.

Following the command of the ground command, the Z-wave satellite around Mars opened its course, and the Mars-1 spacecraft successfully entered the space course two seconds later, and successfully reached the earth orbit seven seconds later.

When the Hwasong-1 spacecraft appeared in Earth orbit and was successfully captured by the radar of the domestic space station, the command center of the space agency burst into cheers.

"Successfully returned!"

"Now the spacecraft has returned to orbit and was captured by the space station's radar."

"Ready to link!"

"Communication link successful!"

The command center of the space agency connected the control module of the Mars-1 spacecraft, and saw the excited smiles on the faces of the astronauts, because they had seen the earth from the glass window.

The shuttle just now was what they were looking forward to, especially Lin Sheng, who was an engineer, went to the space shuttle to Mars. He screamed for a long time in fright, and this shuttle, when the surrounding environment became pitch black , There was even excitement in his heart.

Because, there is a high probability that the shuttle has already started, and they will return to the earth soon.

Although we are still in space orbiting the earth, but seeing the earth with both eyes instead of the orange planet, the senses are completely different.

Now they can start looking forward to returning to the surface.

The space agency immediately announced the return progress of the Mars-1 spacecraft.

The release of this news has a great impact. The return of the Mars-1 spacecraft to the earth’s orbit means returning to the ground. There is only a matter of time in the plan. Even if they are not in a hurry to return, or the spacecraft has some glitches, the The shovel can also dock with the domestic space station, and the astronauts can also enter the space station, and then be taken back to the ground by the anti-gravity spacecraft.

In short, the astronauts are safe.

This Mars exploration mission allowed the world to see the strength of the domestic space agency and Yixing Company in the field of space exploration.

In the past, many countries and institutions could not face up to the gap with domestic space technology exploration, and have always refused to conduct relevant cooperation negotiations with China. Of course, the result is that the country is not suitable for them to conduct relevant negotiations.

For China, international cooperation is mostly about reducing costs, and there is no technical supplement, so it is not necessary.

Now all countries and institutions must face up to the gap with China. At the same time, some countries and institutions have also changed their views. They believe that they should actively cooperate with China in the aerospace field, otherwise the gap will become wider and wider in the future.

At the same time, the strength of Yixing Company is also displayed.

Some countries and institutions have also begun to consider showing goodwill to Yixing Company to strengthen the relationship between the two parties. In just twelve hours after the space agency released the latest news, six countries successively completed the unlimited power vehicle. Import-import review-approval.

After obtaining the relevant import-examination-approval, Yixing can sell unlimited power vehicles to the markets of these countries.

Of course.

There are also problems.

The main reason why many countries have approved the approval of unlimited power vehicles is that they believe that unlimited power vehicles are suspected of technological monopoly, and the space function transmission technology is undoubtedly a monopoly technology, and other companies do not have it at all.

Therefore, local car manufacturers cannot compete with Yixing in the field of "unlimited solar powered vehicles".

This is unfair competition.

Now they have approved the import of unlimited power cars, and they have charged very high tariffs on every imported car on the grounds of 'monopolizing' and protecting local car companies.

After Yixing Company learned of the relevant approvals, it immediately set relevant prices for each exporting country.

Unlimited power cars must be exported in large quantities, because selling cars in countries with different longitudes does not occupy too much transmission energy, which can greatly increase the output of cars.

On the issue of pricing, of course, it is directly linked to customs duties.

There is indeed a "technical monopoly" in Infinite Power Vehicles. It is precisely because of the monopolized technology that the output is limited, and there is no concern about sales at all. Therefore, the pressure of tariffs can easily be transferred to consumers in various countries.

soon.

Yixing Company released the latest overseas sales pricing of Infinity Power vehicles.

The lowest price in the overseas market is about 210 million RMB, and the highest is 520 million RMB, more than half of which are paid tariffs.

At the same time, Yixing Infinite Power Company has also revised its plan for the next year, increasing the number of launched energy-concentrating satellites by five, and increasing the number of Infinite Power vehicles manufactured to 37.

That's a manufacturing quantity that doesn't affect the car's dynamic performance.

If the number continues to increase, the energy transmitted by the energy-concentrating satellites will not be enough, or it will affect other fields, such as the operational performance of high-power Z-wave satellites.

After the Mars-1 spacecraft returned to Earth orbit, it chose the safest way to land.

The first is to slowly decelerate until it is consistent with the rotation speed of the earth, and it is close to the top near the space agency base, and then the anti-gravity system is turned on, and it falls under the weak gravity.

The fastest falling speed is 200 meters per second. When entering a range of [-] kilometers from the ground, it starts to slow down slowly until it lands on the ground.

This is the safest and most stable way to land with an anti-gravity system.

Even if there is a problem with the anti-gravity system midway, the spacecraft also has an emergency system that can open an emergency parachute to slow down after entering the atmosphere.

Of course.

The effect of the parachute is definitely not as good as the anti-gravity system. Using a parachute to land on the road will also lead to a relatively violent collision between the spacecraft and the ground. The safety of the astronauts entering the emergency cabin should be guaranteed. All that's left is the emergency room.

In any case, it is best not to have an accident.

The landing of the Mars-1 spacecraft was also very smooth, because the spacecraft still had some solid fuel left, and after entering the atmosphere, it could directly retrieve the solar receiver device, which is a leaf-shaped single crystal silicon sheet, without any danger in the process.

all the best!

The landing time of the spacecraft was one o'clock in the afternoon. Many people were waiting in the open field, and they saw small black spots appearing in the sky.

The black dot slowly approached and enlarged, and finally appeared completely in front of everyone.

The landing site of the Mars-1 spacecraft is not the open ground, but the super-large glass room in the center. Because it has just returned from space, there must be a certain amount of radiation around the spacecraft.

Everyone could only watch the spaceship land slowly through the glass, and then watch the hatch was opened, and several astronauts came out of it.

"Hula~~" There was a lot of applause.

Senior leaders waved to the lined-up astronauts and shouted into the microphone, "Welcome home, heroes to Mars!"

"Zou Yongcheng, Lu Xiaowei, Lin Sheng—"

The high-level leaders called out the names of the astronauts, and then continued, "You are the first human beings to set foot on Mars. You are the great pioneers of mankind. Your names will be recorded in history!"

"At this moment, everyone is proud of you, proud of you!"

"—"

The speeches of the top leaders were very motivating, especially at the moment when the spacecraft returned, it was even more exciting.

The faces of several astronauts were very excited. They stood firmly in place, with tears on their faces.

Others were also very excited, and some had tears in their eyes.

The scene at this moment touched many people, and I don't know how many people couldn't help but shed tears.

Those were tears of excitement, tears of emotion, but also tears of pride and excitement!

Now is the moment for the astronauts, the moment for Zou Yongcheng, Zhang Liping and others. The Mars exploration mission is completed, and they are the heroes who went to Mars to complete the mission!

Chapter 663 Huge Text Project

The Mars exploration mission is officially over.

There are obvious differences in public opinion on the Mars exploration mission at home and abroad.

Domestic public opinion pays more attention to the return of the astronauts, just like the title of high-level leaders. Astronauts are considered heroes in the country. They risked their lives to carry out the mission and perfectly completed the mission and returned to Earth.

Every astronaut is a hero, and they have all become the focus of public opinion.

Some media made detailed reports on each astronaut, and also published very touching stories, the protagonists of which are the astronauts.

For example, Lu Xiaowei.

Lu Xiaowei has been training hard all the time. He is almost 40 years old, and he is about to end the golden age of astronauts, and he is slowly going downhill.

His childhood dream was to be an astronaut, and after becoming an astronaut, his dream was to actually work in space.

Now Lu Xiaowei has realized his dream and became the first person to set foot on the surface of Mars.

In addition, Zhang Liping is also very admirable, because she is the first domestic female astronaut in space, and she is on a Mars exploration mission instead of working in a space station. Obviously, the former is much more dangerous and stressful than the latter. .

Lin Sheng's story seems to be very ordinary. Many people think that he is "lucky". An engineer was selected to participate in the Mars exploration project and became an astronaut directly.

This will probably be the most dazzling and memorable experience in his life.

When the focus of domestic public opinion is on the astronauts, the astronauts are in the period of isolation. After returning from space, they all need to be isolated for two weeks. .
