The problem with satellite systems is that they are difficult and expensive to update. ／／ Among the ten satellites, the first four can only be barely used now due to design problems at the time, and how long can they be maintained, the Academia Sinica believes that it will be used for two years at most.
It must be replaced.
There are two ways, one is to let it crash back into the atmosphere and send a new satellite to replace it.
One is the space processing plant, which is towed back by the space shuttle for maintenance.
Academia Sinica believes that space processing plants are cost-effective.
High-thrust rockets began to be tested, because they were too expensive, so there was no room for failure.
The replacement and anti-jamming problems of computers were first used in high-thrust rockets.
And then there is the fleet, warplanes, helicopters, rapid reaction forces.
Of course, small things, such as the electronics in the individual weapon system, are the first to be applied because they are relatively easy.
The Space Research Institute is designing a space shuttle, and there are two designs, one is teardrop-shaped, with a plasma engine installed, and only towed and recovered in space.
It does not return to the atmosphere because the plasma engine does not have enough thrust and carries limited energy.
In space, it can use multiple engines to accelerate and decelerate with continuous small thrust to fly and control and get the job done.
But in the atmosphere, there is only one fate.
One is a large air-to-ground shuttle based on a supersonic transport aircraft.
However, because there are too many motives to consider for this kind of air-to-ground shuttle, even supersonic transport aircraft now have many problems, and the biggest problem is the lifespan, whether it is the body, or the engine electronics, etc., all of which have exposed defects during supersonic cruise.
The space agency believes that to be economical.
Either subsonic or, like J2, miniaturization.
Transport aircraft and shuttles are used to perform transport tasks.
More need to consider the load.
Tesla believes that the current situation is only to complete the processing plant and space shuttle first.
Rockets were used as a means of transport to deliver supplies.
Only when the space factory is completed, maybe it will be able to solve the problem.
And the first time to go to the sky is the core module, the core module in the center of the processing plant in the future.
Therefore, the protection is slightly worse and there is no big problem, the key is that the follow-up cabin should go up as soon as possible.
The test capsule on the seabed has completed the test of the spacesuit under near-vacuum conditions, and the artificial environment system has been studied for almost three years.
The most critical thing is the industrial manufacturing process and process in a clean environment.
It is difficult to simulate a gravity-free environment in the Earth's environment.
The Academy of Sciences once proposed an anti-gravity scheme.
Zhang Chun thinks that it is not impossible, but time does not mean much.
It is nothing more than the use of rotation and electromagnetic forces to fight against gravity.
The earth is a very energy-intensive thing.
In the universe, it was originally a state of gravity.
This is the norm for a short period of time.
And to study anti-gravity to deal with the safety of astronauts in hypergravity, it needs to be needed at the dawn of the real space age.
And studying anti-gravity in space is much easier than on Earth.
Guo Hua, who retired to the fairy and served as the head of the Dark Moon Intelligence Center, had a ghost idea again.
She reinvented the gravity-simulating scheme as an anti-gravity scheme.
Secretly delivered to the United States through the intelligence system.
Americans are said to be fascinated by that set of specious theories.
Bai Chongxi actually didn't have much contact with the people of Dark Moon, and he didn't know much about Guo Hua, a rather mysterious woman.
It was not until in the fairy that it was contacted. listened to Guo Hua's little abacus.
Choked on the hot strong tea.
"This anti-gravity solution is not impossible.
It's too resource-intensive, so let the Americans do it, they have the money anyway.
Countries that dare to jump even in pits like bulletproof suits should be very admiring this kind of lofty technology.

Guo Hua's face was cunning.
Zeng Simin, who is in charge of the operation of the science fund, also said: "In fact, Kevlar materials are very useful, and our optical cables and equipment coating materials are all evolved from this compound.
But the Americans use them for bulletproofing, and they are produced on a large scale, and they will not think of anything else in a short time.
Even if you think of it, you have to use the military industrial system to make enough money.
The United States is not strictly a country.
Rather, it is a money-making tool under the control of several major conglomerates. ” Guo Hua looked at Bai Chongxi and said, "When the time comes, Commander Bai will find a way to take down the United States."
The research they do is ours. ” It was at this time that Bai Chongxi was choked.
He looked at Mao Shishan, who was smiling and looking at the information on the side, and said, "Let me tell you, anyone in this world can be offended, and the person who can't be offended the most is a woman." ” Mao Shishan laughed: "I don't care about this, anyway, my net worth can't withstand their little abacus." ” Bai Chongxi got up and left: "I can't stay here anymore, with you, my psychology will become dark."
Lao Mao, you can't go. ” Mao Shishan looked at the materials on the table and smiled bitterly: "Who used to read these materials?"
” Guo Hua and Zeng Simin also got up and said, "It used to be a group of staff officers to look at it again.
You bring these things over and look at them yourself, and you can watch them slowly. ” Mao Shishan's biggest advantage is hard work and study, and he believes that only by figuring it out can he better grasp the direction.
But the disadvantage is also this, he is addicted to learning, and often spends a lot of time on some things, and he knows it himself, but he can't control it.
Mao Shishan looked at the materials on the table pityingly, stood up and clapped his hands, and asked a few staff officers to send the materials back to the staff headquarters.
"Looks like I'm interfering with your work, but it's very interesting, you can make a copy and send me a set.
Let Director Yang give you money. ” Mao Shishan and Bai Chongxi both lived in Daoxiangyuan, Yang Kaihui was the director of the communication department of Daoxiangyuan, and the two of them added a daughter in addition to Mao Anying, but they both studied in Shayang and only came back on their rest days.
There is only one threshold left in the sky for the core module, and that is the fission reactor.
This reactor will also be the start-up and backup power for future fusion reactors.
The key to miniaturization is not in the principle, but in the manufacturing process and material process.
Water-cooled reactors are OK on Earth.
But in space it is not realistic, because it is too heavy.
The reason for the upgrade of this computer is a truth.
Air cooling has much stricter requirements for sealing materials.
Then there is the enrichment of nuclear materials, the casting of special fuel rods, the manufacture of buffer-absorbing materials and shielding materials.
Wait, the speed of research is flying.
Therefore, it should be able to meet the requirements of the space center in time for the overall design and manufacturing of the core module.
However, Fermi proposed a more advanced idea, that is, the use of nano-scale carbon mesh cladding, the use of intermediate semiconductor materials to directly convert the energy emitted by the decay or even fission of nuclear materials into electricity.
Only the quality of the intermediate fuel rods and the fission rate need to be precisely controlled to generate electricity safely.
He still continued his idea of a nuclear battery.
He believes that this eliminates the need for links from nuclear energy to thermal energy to mechanical energy to electrical energy, reduces energy loss, and makes the utilization efficiency higher.
At the same time, this design still has a lot of thermal energy to supply to our system.
The advantage of this design is that it is safe and easy to replace, with one fuel rod being able to burn like a candle until it burns out, and then a new fuel rod continues to burn.
It is also possible to continue to use the decay of radioactive elements for secondary power generation.
It can be made into a very small battery to provide power for a variety of small devices.
The amount of electricity generated by a large power station depends on the amount of such power generation device.
The idea proposed by Fermi can actually solve the problem of storage and utilization of existing radioactive materials.
It can also solve the problem of waste utilization generated by space nuclear power stations.
While researching solar cells and nanotechnology, he deduced the principles of Einstein and Tesla about the motion of particles in microcrystals.
This design places very high demands on nanofabrication technology and is very costly.
The advantage is also very obvious, that is, the utilization rate is very high.
It can be used in a wide range of applications in space factories.
Moreover, this design idea is considered to be based on the direct use of particle properties to study science.
Zhang Chun listened to the report at the Central Academy of Sciences.
"At present, it is very expensive to manufacture such a device, but I think it is still cost-effective in terms of safety and efficiency.
A large part of the reason why it is difficult to make such nanoscale materials and devices on Earth is due to the influence of gravity, but it is not the same in the universe.
Such batteries are capable of being small and provide continuous power to some devices.

Most importantly, it will change the way we think about equipment manufacturing today.
There are a lot of techniques and methods that we can use at the micro level.
So I approve the research work of this nano-carbon nuclear battery. ” Zhang Chun approved the plan of the Central Academy of Sciences.
In any case, nanofabrication technology is a basic technology with a wide range of applications.
It doesn't matter how many flaws Fermi's proposed design has, as long as the manufacturing technology meets this need, the design of the nuclear battery can be modified according to experiments.
