The Three-Body Problem: The Most Competent Wallfacer of All Time

Chapter 164 Technical Problems

Bai Xiangdong continued: "Speaking of which, controllable genetic modification is our dream technology.

"If we can achieve this level of technology, we can completely eliminate the defects of the human body and evolve in the direction we want.

"Only by reaching this level can the process of artificial evolution be completed."

Jiang Yu asked: "Then what is the difficulty of this technology?"

"Controllable!" Bai Xiangdong said: "In fact, our application of genetic technology is still the most handy in the first stage.

"For example, hybrid rice is the master among them.

"From the second stage, technology is out of control.

"As for chimera, we have only scratched the surface. It does not mean that the genes of any species can be chimerized. At present, this technology still has a lot of limitations.

"The technology given by the Trisolarans is awesome because it is controllable, but the control is in the hands of the Trisolarans!"

Jiang Yu suddenly understood: "The first stage of the experiment you conducted before was to use trial and error to let the genetic technology reach the level of the 'pseudo-fourth stage' and complete artificial evolution?"

Bai Xiangdong smiled helplessly: "That's right, it's a pity that my thinking is too naive, as you can see, humans can even grow wings, and there seem to be infinite possibilities in their genes.

"Using this trial and error method, it may not be possible to fully grasp the controllable genetic modification for hundreds of years.

"That's why I decided to turn to the study of chimeras. This technology is more controllable and its practical application will be very long-term.

"At present, my group has mastered the most advanced chimera technology in the world, and there should be a breakthrough within ten years.

"But the distance from artificial evolution is still very far, because it is difficult for human genes to chimerize with the genes of other organisms."

Jiang Yu asked again: "Animal cells split into plant cells. What stage of technology is this?"

"There is no related concept yet," Bai Xiangdong ate and drank a sip of tea and said, "But you can imagine it.

"In the fourth stage, human beings can find the possibility of becoming stronger from their own genes.

"But there are certain limitations, and the gene can only be stabilized through reproduction.

"The trisolarans should have touched the doorway of the fifth stage by using the experiments in Mongolia.

"At this stage, we should be able to find ways to chimerize animal genes. For example, chicken genes are chimeric with centipede genes, and a chicken can grow dozens of legs."

Hearing this, both Jiang Yu and Di Fengyi felt a little uncomfortable.

Bai Xiangdong said with a smile: "Gene technology is not only an exploration of life, but also a blasphemy of life!
"If you want to make yourself stronger, this is a necessary stage."

Then he said: "The discovery of the biological team should belong to the sixth stage.

"I don't have too many concepts at this stage, and I may already be able to make a qualitative change in myself!"

Jiang Yu let out a long sigh: "It's too far away!"

He paused and then said: "Communicate with the biology team more, before your team was one with the biology team, and now the biology team has to work in secret.

"Although your goals are different, the purpose is the same."

Bai Xiangdong nodded.

Jiang Yu said again: "Also, are you sure you can create something against the 'gene missile'?"

Bai Xiang pondered for a while before saying: "You can try it, the only example of a 'gene missile' battle so far is the ETO attack on the Wallfacer Luo Ji a few years ago.

"I have checked the gene missile technology in the 'Poisoned Apple Project', it is just a castrated version of the technology, the theory is incomplete, the key operation Trisolarans did not give ETO.

"The ETO's attack on Luo Ji three years ago should have been instigated by the Trisolarans. We really need to guard against their actions."

Jiang Yu lit a cigarette and remained silent for a long time. The Trisolarans clearly stated in the "Poisoned Apple Project" that they would use "gene missiles" to attack people who have undergone genetic modification.

Jiang Yu was disappointed with those who used the technology of the three-body star, but he couldn't let the three-body star succeed like that.

……

The PDC meeting is still going on, Jiang Yu never expected that these politicians can talk so much.

And after discussing for a long time, there is still no reason to discuss.

Before the implementation of "Project Zero", the seven permanent members of the PDC all had plans to land on Mars.

In this regard, the United States has taken the lead, and has made bold promises since the beginning of this century that it will land on Mars before the middle of this century.

It stands to reason that the United States should already have a detailed plan, so the representatives of the PDC countries all asked the United States to announce their Mars plan.

At first, Washington was unwilling to announce it easily, but in the end, under the pressure of public opinion, amidst the opposition of various countries, Washington finally announced their plan to the PDC member countries.

However, after careful demonstrations by scientists from various countries, it was discovered that the plan given by Washington had many loopholes.

Later, according to people familiar with NASA, this plan has not yet entered the demonstration stage.

This result made everyone laugh and cry. Washington's tightly guarded baby can only be used as a reference at best.

The agenda has finally entered the next stage. Scientists from various countries began to discuss and formulate a comprehensive plan based on the US Mars program.

As soon as this work started, everyone immediately discovered that NASA's plan did not solve the two key problems of going to Mars:

One is to design a reliable planetary spacecraft, and the other is to supply the spacecraft and astronauts.

Astronauts have to stay on the spacecraft for at least six months. After the initial demonstration, the hibernation system cannot be moved to the spacecraft for the time being.

The main reason is that the hibernation system is too bulky. Although there is no resistance in space, every additional kilogram of load will add a burden to the Mars mission. The hibernation system weighing several tons will be a burden on the Mars spacecraft.

The key is that the recovery period after waking up is too long, making it difficult to apply to missions in space environments.

Supplies for astronauts during activities on Mars can be delivered in advance, but during the six-month voyage, they must bring sufficient supplies.

At the same time, the fuel of the spacecraft is also a big problem.The moon is only 38 kilometers away from the earth. After accelerating from the earth's low-earth orbit, the moon can be reached by space gliding alone.

When the Mars plan was implemented, it was too late to wait for Mars to reach the perigee of the earth, and it was necessary to land on Mars at a position more than 9000 million kilometers away from the earth.

The distance between the two is too long, and an acceleration must be performed during the trip.

Not only that, when it is about to reach Mars, it must be decelerated accordingly to enter the orbit of Mars, otherwise it is easy to pass by Mars.

Since the hibernation system cannot be used in space for the time being, everyone puts all their hopes on the nuclear fusion system.

As long as there is a steady stream of power, bring more supplies, and build the spaceship a little bigger, the problem can be easily solved.

The research on controllable nuclear fusion technology is about to succeed, but it is still short of finishing touches.

Ding Yi estimates that controllable nuclear fusion technology will not be available until at least early next year.

But it is only with this technology, and there is still a long way to go in the application stage.

Fusion technology won't be able to drive the large engines on Mars spacecraft for at least a decade.

The aerospace engine is too huge. Take the liquid fuel engine of China's Long March [-] rocket as an example. The five engines of the first stage of the rocket that are responsible for breaking away from the earth's gravity are each as high as two floors!

Even for the third-stage rocket used in space, each of the three engines is more than three meters high.

The nuclear fusion engine will definitely be smaller, and its structure and operating principle are completely different from rocket engines, but these things cannot be designed in a short while.
