The United States announced that it had cracked China's bulletproof suits and said that China's bulletproof suits were too complex and uneconomical.
The United States invented a Kevlar chemically synthesized bulletproof material.
This material is better than that of China, and the protection is stronger.
Helmets and bulletproof vests made from this synthetic material are capable of withstanding pistol and rifle bullets.
The United States began to promote such helmets and vests to the whole world.
DuPont maintained a large production line to supply orders from the U.S. military and British, French, Russian, and Japanese arms dealers.
And with a shield, it is natural to strengthen the spear.
The United States believes that only artillery cannot be defended by such vests.
At the same time, they also want to sell newly designed tanks and cannons to other countries.
There was a boom in tanks and artillery in the world for a while.
The only thing in the world that does not have massive tanks and artillery is China.
When a foreign reporter asked Wu Hao what was going on, he said that China is a place with many forests, rivers and swamps.
Tanks and artillery can't be put on the table in China, so China does not make such weapons.
In September, the Yinchuan Space Launch Center launched the Relay 2 satellite.
This time, the wreckage of the two thrusters successfully entered the predetermined orbit in the second section.
But the first section failed, and the wreckage failed to rise to the intended altitude and speed, and after two laps, it crashed into the atmosphere over the United States.
Most of them burned and a small part of the wreckage fell to the ground.
However, Relay 2 accurately entered the synchronous orbit and was positioned over Lake Baikal with little adjustment.
Relay No. 1 played a key role in the transmission of the TT&C signal.
Half of the monitoring ranges of the two satellites overlap.
The overlapping part of Zhenhai is in the area of the Soviet-Japanese confrontation.
This ensures that no radio communication is missed in this section.
At the same time it is possible to monitor large-scale military movements, in particular, any movement of armored groups and airfields. have become the object of monitoring.
A newspaper in the United States carried news and pictures of what was said to be a UFO crash.
Since the first thruster has already been pushed to a fairly high height.
It then returns to the atmosphere because the thruster fails during propulsion.
So it's basically gone, and only a very small piece of the thickest thruster bottom remains.
It really looks like a flying saucer wreckage.
However, the US side then denied that it was a flying saucer, but did not explain what it was.
The two-section thruster is actually a detection experiment, which tries to accelerate the detection of the Earth's ionosphere by sending back some electronic signals through the sensors all the time.
The geostationary satellite has an altitude of 36,000 kilometers because it is a calculated fixed orbit.
The first section has actually advanced to about 400 kilometers.
But the second thruster sent back the radiation along the way.
The space center has obtained key data from the study of the Earth's strong radiation belts and ionosphere.
The measured radiation on the first thruster is very low.
But there is an atmosphere in this area, and the thrusters that lose power quickly fall off.
This is the first time that humans have confirmed the existence of a strong radiation layer and an ionosphere.
With this idea, the engine on the second section of thrusters was not turned off.
Measurement and control personnel try to keep it in motion until the engine runs out of fuel.
Its goal is the Moon, which is 380,000 kilometers away.
Although only intermittent numbers can be sent back.
As a result of this discovery, it caused a lot of trouble for the space factory.
That is what kind of track should this plant be set on.
Tesla insisted on about 100,000 kilometers.
Because it's easier to go to the moon.

It's harder to return to the factory after returning to Earth.
However, if this is the case, it is necessary to complete the radiation protection measures of the capsule shell, the simplest is the radiation protection material. coating or tile.
The second is attitude adjustment and docking.
The engine was solved, but it required a very responsive electronic control system.
Radiation protection can be carried out in the study of materials for nuclear fusion, and experiments can be carried out on submarine observation stations with docking electronic control systems.
In addition, there is the miniaturization of nuclear fission reactors.
If you can achieve the miniaturization of nuclear bombs, you may not be able to achieve the miniaturization of nuclear power.
The other is a completely new computer design.
It all takes time.
Due to a flaw in the second satellite launch.
And the number of space exploration missions has increased.
Relay 3 and 4 satellite launches have been postponed.
The command determined the launch of at least eight relay satellites.
To be able to control the airspace of the USSR and the United States.
It is believed that only these two countries may be able to threaten space security in the future.
In Kunlun Mountain, Zhang Chun encountered great trouble.
The Kunlun Mountains are similar to the Altai Mountains in that the higher the mountain, the more precipitation there is, but at an altitude of five or six thousand meters, the water is in a frozen form.
The precipitation in the Kunlun Mountains is much less than in the Altai Mountains.
Some glaciers exist only between ravines and crevasses.
Some of the lower altitudes are tundra, thick permafrost.
Zhang Chun was accompanied by rangers and members of the geological team, who said that the permafrost here is hundreds of meters thick.
It's summer.
Zhang Chun heard the subtle sound of running water under his feet.
Reiz heard the same voice.
All the men dismounted and retreated to safety.
A soldier fired a shot with a sniper rifle at a distant point.
That's a flowering bomb.
But the bullet went to the ground.
There was only a hollow sound underground.
There was no movement on the ground.
"It's empty down here."
Even the geology team members were frightened.
Zhang Chun lay on the ground and listened carefully.
There is not only the sound of flowing water underground, but also the sound of some rivers rushing.
Right in the heart of the valley.
But on top of this dark river, there are still abundant plants and trees.
Zhang Chun remembered the words of the Tundra Grassland Management Office.
"The vegetation and animals here are more than 10,000 years old.
In the summer, the permafrost here melts.
It may have been a little bit at first, but we saw that the moss and fabric did not collapse, but remained in place because they supported each other and the roots were strong.
However, with the extension of time, the active layer became thicker and more stable, but the freeze-thaw cavities below became larger and larger, and finally converged into an underground river.
A hollow was formed. ” "But the active layer of vegetation alone can't support such a huge cavity."
"Yes, the movable layer can't support it, but you forget that the active layer also has water seepage, and the water seeps all year round, and some trees have a much deeper root system than the aboveground part, and this water will freeze down the root system, forming a support column.
So it's not entirely empty underneath.
Rather, there are countless columns that are made up of a combination of roots and ice. ” In this area, woods and meadows appear at intervals.

It's beautiful, but the danger is incalculable.
Lizin gently picked at the grass with a stick, and beneath it was a black hole, creeping plants mending the hollows where some animals had fallen.
The soil layer on top of them is very thin.
Incredibly, the surface is not without rivers, and the streams on the surface are very clear and gurgling.
And there was no interruption.
If it weren't for Zhang Chun and his wife discovering the underground river in advance, this group of people would not know what danger would be.
Because there was a large group of men and horses, Zhang Chun did not dare to take risks, theoretically speaking, the forest area was safer.
But Zhang Chun still chose the more difficult hillside.
In fact, animals may be more sensitive than humans.
The slopes of the mountains are full of migratory paths, and in the center of the valley are only small animals.
The electromagnetic sensors on the fighters kept barking, and they were getting louder and louder.
Walkie-talkies and telegraph interference grew, and communications were simply cut off.
This indicates that there should have been iron ore or other magnetic deposits in this generation.
Zhang Chun looked at the sky, the weather was clear, and the sun was shining.
However, this is the northern slope of the Kunlun Mountains, and the summer rains are coming.
Zhang Chun asked: "How about the insulation performance of everyone?"
” "Well, the clothes and shoes are insulated," Tao Nan said. ” The platoon commander of the guard platoon smiled and said: "This clothes, we are going to pass through the enemy's power grid and barbed wire."
Although the hanger has thin metal wires, it is made of leather and synthetic materials, so there is absolutely no problem. ” Zhang Chun frowned and said: "If it rains, it is best to put on a poncho and not ride a horse, but I hope we can get out of the electromagnetic anomaly area before it rains."
Imagine what it would be like if there were thunderclouds over here. ” The crowd looked at the sky.
The guard platoon commander shuddered for a moment: "We may lose some horses."
We had the equipment, Marco didn't. ”
