Lin Sheng opened his mouth in embarrassment. He even wanted to escape a little bit. Fortunately, other people are used to it, and they can't ask an ordinary technical engineer to really face the danger of life with the mental capacity of a standard astronaut. Sometimes, it is difficult for even them to maintain absolute composure.

Zhang Liping immediately operated the link to the ground, and made a report excitedly, "Report!"

"This is Mars-1 spacecraft, 35 kilometers from the surface, tilted at [-] degrees. The spacecraft accelerated successfully!"

"Hula-"

At the same time, in the control cabin of the spacecraft, the noisy and transformed electronic sounds could be heard on the opposite side. The chaos also represented the excitement and joy of the ground command room.

The commander of the space agency's Mars mission also said excitedly, "Congratulations, heroes who have made it to Mars!"

"You have passed the most dangerous moment, and as long as you follow the original plan, you will be able to return successfully!"

Chapter 661 The idea of ​​building a base on the surface of the moon

Space agency.

In the command room of the Mars exploration mission, everyone was cheering excitedly. They were very excited, because everyone knew that the most dangerous moment of the mission had passed.

Each stage of the Mars exploration mission will have a safety level assessment, and the most dangerous is the acceleration stage of space shuttle and Mars liftoff.

The danger of the former is that there is no absolute guarantee that personnel will not be affected in any way during the space shuttle.

This is mainly because no relevant experiments have been done before.

Looking at it now, at least in the short term, the astronauts' bodies have not been affected in any way.

The second most dangerous stage is the moment when Mars lifts off and accelerates. The spacecraft will suddenly vibrate and change direction at the moment of acceleration. It may be due to air flow, intelligent control system or other failures that may cause the spacecraft to tilt too far, causing Risk of immediate crash. .

The most dangerous thing is air flow. There is a lot of air on Mars. If there is a lot of air, it will be affected by wind, and there will be some strong convection, which will directly affect the movement of the spacecraft.

Even if it is tens of kilometers away from the ground, if the tilt angle of the spacecraft is suddenly changed, and the upward speed slows down at the same time, it may also be affected during the adjustment process.

There are many effects that can cause danger. After passing through the danger of the moment of acceleration, as long as it ascends into space normally, the safety factor will increase a lot.

At this time, it cannot be said that the spacecraft is absolutely safe, but if there are no major failures or accidents, there is no problem returning to Earth.

In the process of reaching the earth from Mars, a space shuttle is also required. As long as there is no problem with the Z-wave satellite device, there will be no problem with the space shuttle.

Even if there is a real problem and the spacecraft fails to complete the space shuttle and consume all the remaining solid materials, the spacecraft can still leave Mars and rely on the transmission of solar power to slowly fly back to Earth.

This process may take several months, but as long as the spacecraft and the people on it are safe, it is not a big deal if it takes longer.

In the vast universe, there are still many dangers, but the performance of the spacecraft is very strong, and the probability of an impact event in space is very small. Even if an impact event is possible, the spacecraft can still be controlled manually.

Therefore, the main risk is still concentrated on the failure of spacecraft components.

Among the various parts of the spaceship, the most important is of course the energy system, which is the leaf-shaped light energy receiving converter.

The light energy receiving converter is most likely to fail at the leaf-shaped monocrystalline silicon slices. The spacecraft is loaded with some replacement slices. If there are too many single crystal silicon slices that have problems, astronauts need to go out of the warehouse to replace them. .

There are great risks in this process.

In addition, the space link device of the light energy receiving converter may also have problems.

At this time, engineer Lin Sheng is needed. The space link device is inside the spacecraft. Lin Sheng has the ability to repair the failure of the link device, and even manually replace the beam device on the main panel.

The probability of problems with other devices of the spacecraft is not high. Even if there are problems, the interior can be repaired.

As long as there is enough energy, the spacecraft can slowly return to the earth.

Compared with the Mars-1 spacecraft, the space agency and Yixing Company are more concerned about the number of astronauts, and the safety of personnel is the most important thing.

This is not a people-oriented or morally restrained, humanitarian statement.

Because we already have the corresponding manufacturing technology, the loss of the spacecraft is only a loss of part of the money. Even if the spacecraft returns to the earth, it needs to go through detailed inspections, repairs, and a series of radiation cleaning before it can be put into use again.

Even if it is an intact spacecraft, the value of a few astronauts is simply incomparable, especially for Yixing Company, experienced astronauts can even be said to be priceless, and it is very difficult for them to find a replacement things.

Therefore, the lives of astronauts are the most precious wealth.

After passing through the most dangerous early stage of acceleration, the Hwasong-1 spacecraft will continue to accelerate until it enters a normal orbit.

Because it is no longer affected by the Martian atmosphere, the light energy receiving and converting device is fully activated, and energy is no longer a problem.

What needs to be done now is to continue to wait until the spacecraft can enter the predetermined orbit, and then proceed to the next step, shuttle and return to the earth.

-

Hwasong-1 spacecraft.

The astronauts knew that they had passed the most dangerous stage, and their mood became much more relaxed, and they couldn't help but smile on their faces.

Although there is no real return to the earth, at least it is safe for the time being, and the return can already be expected.

Everyone desperately wanted to get back to the ground.

This kind of mood is not something that ordinary people can feel. It's just half a month of working on the spaceship, but it seems like a long time, the main reason is that they are too far away from 'home'.

The journey to Mars was really nice, but they were nervous all the way through the work, and being around Mars and in space around Earth was just not a concept at all.

When they are in orbit around the earth, they can see the earth with their eyes, as if their hometown is close at hand, but staying on Mars in the distance seems to have been abandoned by their hometown, or even exiled in the universe, and their mood will change. It was very dull.

Everyone is looking forward to returning to Earth.

At the same time, the progress of the Mars exploration mission was also released, and was reprinted and reported by the international media, "The Mars-1 spacecraft has passed the most dangerous moment and successfully ascended into space, and will soon be able to enter the predetermined orbit. Orbit of Mars."

"The Mars exploration mission can be said to have succeeded for the most part."

"According to the news released by the Space Administration of Z and Yixing Company, after the spacecraft officially enters the orbit around Mars, we can already look forward to returning to Earth."

"When the most dangerous moment is over, the spacecraft can slowly fly back to Earth relying on its own performance."

A large number of international media reported that the situation of the Hwasong-1 spacecraft received more attention, and many people were discussing it in amazement.

Even the successful return of the spacecraft is enough to cause a lot of discussion, because the technical strength involved is too powerful.

At this time, Zhao Yi is still in the space agency, and he will work until the spacecraft successfully returns to Earth.

After learning that the spaceship had passed the most dangerous moment, he also took a long breath, knowing that he could look forward to the return of the spaceship.

Unable to do anything on the ground, he also began to think about the next stage of work.

After the Mars exploration mission is over, the next stage of the exploration plan must be started. In the solar system, Mars is the planet most similar to the Earth, but what is certain is that Mars is not suitable for human habitation.

The main component of the Martian atmosphere is carbon dioxide, followed by nitrogen and argon, with only a small amount of oxygen and water vapor. At the same time, the temperature difference between day and night on Mars is relatively large. Compared with the earth, Mars is very cold, even at the equator of Mars The location, the temperature at night can be as low as tens of degrees below zero.

The reason why the international aerospace industry is very interested in Mars exploration is because Mars is similar to the earth. Another reason is that compared with other planets, Mars is very close to the earth. Studying Mars is very important for human beings to go out of the earth. significance.

For Yixing Company, the Mars exploration mission is just an exploration experiment, even within the solar system, the value of Mars is not very great.

In the next phase of space exploration, costs and benefits need to be considered.

Zhao Yi has already thought about the direction of exploration in the next stage, and there are two main directions.

One is to explore terrestrial planets.

Earth-like planets are undoubtedly very valuable. Finding planets similar to Earth, such as the atmosphere containing a lot of oxygen, and the presence of a lot of water on the surface of the planet, all have the basis for human and biological survival.

As long as similar planets undergo certain transformations, they may become the destinations for human planetary migration.

Of course.

Similar to the exploration of planets, it is very difficult to obtain income in the short term.

If only economic interests are considered, the most valuable are planets with valuable mineral deposits. For example, some planets have very high densities, and there may be a large amount of ultra-precious metals on the surface.

The ultra-precious metal does not refer to gold. In fact, for the mining of minerals on the planet, gold is no longer considered high value.

Some metals are very rare on Earth, such as rhodium.

Rhodium is a hard, silvery-white metal that is highly reflective and very resistant to oxidation.Even when it is heated to the melting point, the oxygen in the air is only temporarily absorbed, and it is released again in the process of solidification.

At the same time, the corrosiveness of rhodium is also very amazing. It is insoluble in most acids and slightly soluble in aqua regia, so it has a wide range of industrial applications.

However, the content of rhodium in the earth's crust is only one part per billion.

In the international precious metal market, the price of rhodium per gram has been above US$[-], and sometimes even more than US$[-].

Other precious metals, such as plutonium, iridium, etc., are very valuable metals.

Precious and rare metals are only one of the goals of planetary mining. On high-density planets, new discoveries may be made, such as the discovery of new elements, which can be applied to industrial manufacturing and aerospace development. At the same time, new discoveries are also possible. It will make great progress in science and technology, thereby creating new markets.

and many more.

Yixing Company is a joint-stock company operating normally. Even if it is doing space exploration work, it needs to consider the interests of shareholders. In the process of space exploration, it is best to create benefits.

Of course.

The exploration of terrestrial planets and the mining of planets are all follow-up work, which is only one direction for the time being.

First of all, technical problems still need to be solved.

Yixing Company does not need to consider large-scale space exploration, that is, to manufacture spacecraft for large-scale detection, but launching probes to other galaxies will definitely require super-large Z-wave generating satellites.

Compared with the detection of galaxies, the power of existing Z-wave satellites is seriously insufficient.

Theoretically speaking, the Z-wave satellites around Mars can open the space channel at a distance of no more than 20 billion kilometers.

This is already theoretical data.

Although most of the universe is a vacuum environment, it has little effect on the distance covered by the Z wave, but "very small" also has an effect.

There is no absolute vacuum in the universe, and there are particles in space. At the same time, just like the theory of the Higgs field, even in an absolute vacuum, there will be Higgs bosons. As long as there is Particles with less mass will have an impact on Z-wave coverage.

When the coverage area is too large, the extremely low or even negligible particle density will have a greater impact, and the Z-wave coverage area and compression ratio will also be limited.

If you want to cross galaxies, and the distance is calculated in light years, the power of the Z-wave satellite must be greatly increased.

Through a series of calculations, Zhao Yi came to a conclusion——

In order to travel in units of light years, the power of the Z-wave satellite needs to be increased by at least [-] times.

Fifty times is not easy to talk about.

Spaceships are able to span galaxies because of the energy support of nuclear fusion, which can deliver ultra-high power exceeding one million kilowatts per hour in time, while the power level of Z-wave satellites is only in units of 'kilowatts'.

If you want to achieve a [-]-fold increase, it is almost equivalent to half a sun-encircling energy-concentrating satellite to supply a Z-wave generating device. At that time, the receiving and converting blades of the Z-wave device will cover a very large area.

There are too many technical problems in it. Even if such a large-scale blade device is successfully placed in space, the probability of problems is very high.

"How to solve it?"

Zhao Yi thought about it deeply. After he had a direction and an idea, he must study and solve it.

The advantage of Yixing Company in the direction of space exploration is that they only need to launch probes to detect valuable planets, and they don't need to consider the safety of the shuttle route.

The latter is the main reason why spacecraft shuttles are limited.

very open.

Zhao Yi thought of a way - to place the Z-wave device on a planet without an atmosphere.

The surface of the moon is a good choice, because the atmosphere on the surface of the moon is negligible, and it is relatively safe to place the device on the surface of the moon. It is even possible to build a living quarters on the surface of the moon so that the device can be monitored at any time. Carry out control, maintenance and other work.

"On the surface of the moon, building a large-scale Z-wave generating device can greatly increase the coverage of single crystal slices, provide higher power, and be able to directly shuttle between galaxies."

"Ordinary anti-gravity spacecraft can carry detectors to realize shuttle."

"As long as there are high-performance detectors, more information can be collected—"

"This is the first step, a very crucial step!"

"Moreover, there are many advantages to building personnel on the moon. The moon has no atmosphere, and a super-large radar system can be installed later to observe the universe—"

Chapter 662 Is this considered to be an expansion of territory?

The benefits of building a base on the lunar surface are simply too many.

The moon has no atmosphere. Staying on the surface of the moon is like staying in the universe. From the perspective of scientific research, a large telescope placed on the surface of the moon can be used for more in-depth astronomical research, and can observe clearer, More phenomena.

In addition, a large-scale Z-wave generator can also be built. The Z-wave generator uses the transmission of solar energy as the energy source and is built in orbit around the earth. It is not a good choice, mainly because the earth's atmosphere covers too much.

Even in a space of hundreds of kilometers, compared to the universe, there are still a large number of particles, which will directly affect the coverage of the Z wave.

At the same time, it is not easy to increase the power of Z-wave satellites, because the space is full of dangers, and physical dangers are the most deadly. The coverage of monocrystalline silicon sheets will be greatly affected. limit.

If it is the surface of the moon, the situation is different. The impact on the surface of the moon is so thin that it can be ignored. At the same time, the moon has gravity and the ground. The ground of the moon is a natural heat sink, and the ground can arrange a large number of monocrystalline silicon wafers. , no need to consider the area of ​​​​occupancy.

Regardless of the occupied area, the power provided by space light energy transmission and conversion technology is even better than that of nuclear fusion devices. The main advantage is low cost and no complicated operations such as 'replacing fuel'. .

After a nuclear fusion device has been used for a period of time, the fuel needs to be replaced.

Replacing raw materials on the earth is already somewhat complicated work, and it is conceivable to put it on the moon.

In addition, without considering complex issues such as technology authorization, the manufacturing cost of nuclear fusion devices is also very high. The construction cost of providing millions of electric power sources reaches more than 200 billion yuan, and considering fuel costs and service life, etc. The problem is that the energy supply cost of the nuclear fusion device exceeds 250 billion yuan per million kilowatts.

This is without considering the difficulty of changing fuel on the moon.
