As a mage, I just want to pursue the truth

Chapter 267 The Fourth Moon Landing

The topic of moon planting is not new, it is the only one for Blue Star.

Even American just took some soil brought back from the moon and tried to plant it.

Not to mention other countries, I haven't been there yet.

For the time being, it belongs to the unique needs of Huaguo.

The Huaguo astronauts will bring up not only the original seeds of Blue Star, but also a genetically modified seed with the strongest vitality carefully cultivated by Jiang Yan.

Jiang Yan could only perceive that this seed had the most vigorous vitality, a seed mutated from rice.

You must know that Jiang Yan has been engaged in the research of sea rice before becoming a mage.

After becoming a mage, he took the cultivation and practical value of sea rice a big step forward.

This time, it is specifically aimed at Huaguo's plan to build a base on the moon, abandoning all requirements on yield, taste, insect resistance, etc., and focusing on improving the survival of seeds in harsh environments.

"If we can successfully grow rice on the moon this time, then we might be able to eat the rice grown on the moon next time we come to the moon." Chen Dong showed a longing look.

"Actually, going up to plant this time is only our secondary purpose.

The most important purpose of this moon landing is to build a small base.

Although the prepared building materials are as convenient as building blocks, it is necessary to wear a heavy spacesuit on the moon and adapt to the gravitational force that is completely different from that of the blue star.

The influence of solar wind and temperature difference also needs to be considered. I have a hunch that our base construction is not as easy as imagined. "

Ye Neng is the oldest astronaut among the astronauts in this moon landing program, and the three of them have spent much more time cooperating together than with their own family members.

Ye Neng usually has the image of a stable and big brother in the team. He considers problems comprehensively and holds pessimistic expectations at all times, but handles problems optimistically and positively.

He is also the leader of their three-person team.

"At present, most of the building materials have been moved up by us during the previous moon landings.

We have done full testing whether it is on the moon or in the simulated environment of the blue star.

Brother Ye, don't be too pessimistic.We're sure to pull it off this time. "

In Huaguo's previous three moon landing plans, except for the first one, some special building materials were brought up in the latter two according to the established plan.

And fixed near their chosen base location.

American originally planned to land directly on Mars and build a base on Mars.

But because Huaguo's progress far exceeded expectations, landing on Mars was not as easy as they expected.

Therefore, American chose to fine-tune their plan, and they also planned to build a small base on the moon first.

Since there is no transit station like the moon-orbiting space station, the cost of American will be tens of billions more.

Of course, there are also reasons why various costs of NASA, including but not limited to labor costs, are higher than those of CNSA.

The reason why American would rather change the plan and build a base on the moon is not because of the economic value brought by the moon landing itself.

There are abundant mineral resources on the moon, including lithium ore, phosphate rock, and rare earths, which have been booming in recent years.

However, Bluestar's current technology is still a long way from low-cost mining on the moon.

The round-trip transportation cost alone is at least ten times that of buying mines directly from Blue Star, even though the price of lithium mines has been soaring again and again.

This is the same reason that Russia took the lead in launching a manned rocket back then, and American would forcefully land on the moon even if the test was incomplete and the safety risk was extremely high.

American needs to build a global image of technology leadership that cannot be questioned.

Among their three pillars, energy is almost lost, and the pillar of technology cannot be shaken any longer.

Huaguo's bio-storage technology had already had a great impact.

Including brain-computer connection VR, these products have caused a very adverse impact on American on a global scale.

Let's put it this way, the countries headed by American hope to reconstruct the image of Chinese people in the global public opinion field.

However, when Huaguo's unique technology and unique products are circulated around the world, it is easy for foreign people to question this kind of public opinion construction.

If Chinese people are as unbearable as the BBC, CNN, etc. media say, why can they create the world's leading technology?

The aerospace field is more intuitive, especially the fact that space indirectly reflects the country's scientific and technological strength, which is the internal relevance of public opinion created by American itself.

What American cannot accept is that Huaguo has repeatedly broken through the public opinion trap they constructed in terms of national image.

Huaguo and American are staking their land on the moon one after another, making some countries very vigilant.

Especially Ah San, Ah San has repeatedly stated that the moon is the common property of mankind, not the territory of certain countries.

In order to avoid the destructive mining of the moon by some countries, the development around the moon must be discussed by all the countries of Blue Star.

For Hua Guo and American, Ah San's proposal was not even a formal discussion, at most it was their own complaints.

Netizens in Huaguo ridiculed the news even more:
"If you want to interfere with our construction of the moon base, the third brother should first have the ability to land on the moon."

"Ah San is a typical person whose heart is higher than the sky and fate is thinner than paper. I haven't fully understood manned aviation yet, so I just think that I might go to the moon in the future?"

The discussion from the outside world, the moon landing trio who have been receiving training at a special spaceflight base, have no knowledge of it.

Even if they knew about Ah San's proposal, they would just laugh it off.

Ye Neng was relieved by Chen Dong's optimism.

As a veteran who has undertaken many aerospace missions in China, he knows the importance of having optimists in the team:
"I believe we will successfully complete this lunar base construction mission, or must complete it.

It's just that I don't think it will be as smooth as we expected.

Success after going through certain twists and turns is also success.

But in order to reduce the twists and turns experienced in the middle, we need as many plans as possible.

It is necessary to rethink the problems that may arise.

Didn't we also have an accident when we first orbited the space station around the moon? "

Huaguo's space station orbiting the moon is located at the point of orbiting the moon, that is, the "halo orbit" of the L2 point mentioned earlier.

The halo orbit was first defined in NASA's plan in the 80s.

At that time, NASA wanted to set up a data relay satellite on the far side of the moon in the halo orbit, and later this plan was changed to a space station around the moon.

Later, this position was occupied by Chinese people.

Satellites orbiting the halo maintain line-of-sight contact with the Earth and the far side of the Moon at all times.

Seen from the surface of the moon, the subtended angle of the entire halo orbit is only 6.2 degrees.

"You mean that after we docked, we found that the satellite had shifted and couldn't continue to stay in the halo orbit?"

To keep the satellite in the halo orbit, it needs to consume energy for station keeping.

At that time, when their launch satellite was docked with the moon-orbiting space station, this balance was affected.

The low-thrust direction of the orbiting space station was affected.

That is to say, after they enter the space station, if they continue to operate according to the established orbit, they will leave the halo orbit.

"Yes, it was because we were above the moon and didn't land on the moon. We could still get technical support from Blue Star." Ye Neng nodded.

At that time, the Chinese scientists of Blue Star proposed a long-term station optimization method on the lunar halo orbit in response to the deorbiting crisis of the lunar space station.

The method uses discretization of each half-revolution into segments and uses a set of pseudo-pulses for each segment.

The eigenvelocities and matrix inequalities of the pseudoimpulse are used to convert the problem into a large-scale linear programming formulation.

The terminal constraints can be expressed as linear matrix equations using numerical partial derivatives of the reference orbit.

At the same time, an iterative shooting algorithm based on the full ephemeris model and differential correction is used.Preliminary simulations and comparative results for a one-year long-term stagnation strategy are presented.

The algorithm used to maintain the new low thrust for a long time was estimated by the above method.

And recalculated the operations they need to perform, and the thrust-to-weight ratio required for the space station.

At that time, everyone at the Blue Star launch base was panicked.

Breaking away from the orbit of the halo, according to the calculated trajectory, they will be forced to land on the moon.

After landing on the moon, even if there was no physical damage, the oxygen and supplies were not enough to support them until they waited for Blue Star's rescue.

Not to mention, if the space station orbiting the moon is to be relaunched, American may be the first to occupy the L2 point.

The occupation of point L2 is also unacceptable to China.

You must know that this means that they will build a base on the moon, not to mention starting over, and investing more money.

Huaguo's budget in the aerospace field is less than half of American's, and every penny is precious.

At that time, in order to solve this problem, Huaguo sent a mage with a background in mathematics to participate in the solution of the problem, and spent a magic coin to rent the brain of the biological cloud.

This is also the first time that Blue Star Bio uses the brain function of the biological cloud.

Zheng Li, who was notified of the news at the time, was surprised that the function I set up has finally been used by someone after so long.

If you don't use it anymore, I will doubt whether this function is a decoration.

Huaguo discovered the function of the biological cloud brain, which is suitable for top geniuses to use when tackling world-class problems.

Ye Neng continued: "You must know that there are high-energy particles and solar wind on the moon."

"Communications with Blue Star will definitely be affected."

Unlike growing vegetables on the moon, there are many related studies on the communication between the blue star and the moon, because this is a communication problem.

And the lunar exploration vehicle will have the need to solve the communication problem.

Data from the Lunar Rover needs to be sent back to Bluestar.

As early as the 40s, before the founding of Huaguo, Bluestar scientists were already studying how to achieve daily communication between the moon and Bluestar.

In the meeting minutes of IRE, there is a complete solution for daily communication between the moon and the blue star. IRE is the name of IEEE before it was renamed.

Of course, this solution is only related to the principle, not to say that they really solved the problem.

"Actually, the most important thing is that there will be serious delays or even failure to communicate with Blue Star."

"If we encounter any accident on the moon, we can only rely on ourselves at the first time.

So it's always good to be prepared. "

Chen Dong nodded and said, "Would it be better if we built an LTE base station at the moon base the second time?"

In Huaguo's lunar base construction plan, the first time to go up is mainly to complete the main living area and then plant vegetables.

The second time you go up, you need to set up supplementary environments such as LTE base stations and research environments.

Ye Neng said with a smile: "Everything is foregone, and if not forewarned, it is useless. We need to make more preparations."

Huaguo's plan to land on the moon and build a lunar base is scheduled for mid-March, which is the day when the dragon raises its head.

In fact, with the growth of the economy and national strength in these years, the Chinese people have begun to pay less and less attention to symbolic events at the national level.

Spaceflight like these years, except for the sensational effect caused by the moon landing, which was discussed by everyone at that time, other times seem to be very ordinary.

Only aerospace enthusiasts will continue to pay attention, and most people just click in after seeing it on the hot search and then quit.

To be honest, the aerospace field is too far away from the general public, and there is nothing to do except to get a 666.

There was an accident in the docking of the space station around the moon, which was later reported by the official media of China. Everyone didn't quite understand the ins and outs of the accident.

When a car is involved in an accident, most drivers can speak clearly and logically. Few people have ever driven a manned spaceship or a space station.

Not to mention that the space station orbiting the moon cannot be found in history.

The highest ranking of the orbiting space station on Weibo's hot search list was because it took the position chosen by American.

This is the same reason as you built your house on a location carefully selected by your neighbor, especially this neighbor you still don't like.

This time Huaguo's moon landing has aroused the attention of the people.

Because this time a base needs to be built on the moon, and the official media will broadcast the whole process live.

The official media also authorized the live broadcast to Bilibili, WeChat video account and Douyin.

The momentum was huge.

The communication between Bluestar and Moon mentioned above by Ye Neng and Chen Dong was affected by unexpected circumstances.

Most of this kind of accident will not happen. After the communication between the moon and the blue star passes through the lunar space station, the delay under normal circumstances is about three to five seconds.

"Space tourism has already been realized, and I don't think it's far away to travel to the moon."

"In my lifetime, I will definitely see it in my lifetime"

"I already regret that I didn't choose to go to the military academy after the college entrance examination, and then become an astronaut.

Building your own base on the moon is too romantic. "

"I heard that not only will we build a base on the moon this time, but we will also grow vegetables. Does anyone know what kind of vegetables to grow?"

"The official spokesperson of the aerospace department mentioned before that rice will be grown, but rice is only one of them. He said that there will be many kinds."

"Can you sell the seeds brought back from the moon, I really want to plant one.

If anyone can get it, you can contact me, and the reward will definitely be huge.”

"Wouldn't it be 50 people walking upstairs? Even if a normal person wants to get a seed, he knows it's impossible, and he's just joking at most.

Upstairs said all the rewards, I feel a little strange.

Do you want to say something about the northern netizens? "

On the forums dedicated to aerospace, netizens discussed this moon landing very enthusiastically.
