A big country of aerospace with black technology

"Xihe-1 is about to enter its predetermined orbit and is adjusting its posture."

Within the vast hall, various sounds sounded in an orderly manner.

Staff members in dark blue uniforms were busy coming and going.

Continuously decode, summarize, and analyze data transmitted back from hundreds of millions of kilometers away.

Geng Bo sighed: "Sun, we are finally here!"

Since ancient times, countless literati and poets have chanted about the sun.

It is the first time that such a clear image appears in front of everyone's eyes.

Xihe, the sun-controlling goddess imagined by the ancients.

"The Classic of Mountains and Seas, Great Wilderness South Classic": "Beyond the southeast sea, between the sweet waters, there is the country of Xihe. There is a woman named Xihe, who bathes in the sweet water every day. Xihe is the wife of Emperor Jun and has ten children. day."

But for thousands of years, no one has ever been so close to the sun.

"Our Xihe will reach perihelion soon."

Zhang Xingyang touched his chin with one hand and looked deeply:

"This is just the beginning of the test for us."

Although mankind has developed vigorously in aerospace technology since the 1950s.

However, deep space detectors have long been monopolized by two superpowers.

Longguo's deep space exploration started with the Chang'e lunar exploration project a few years ago.

Although in this process, more experience has been accumulated.

However, the perihelion, which is hundreds of millions of kilometers away from the earth, is still a great test of the strength of the Dragon Kingdom's aerospace industry.

Among these, what worries Zhang Xingyang the most is the cooling system of the Xihe satellite.

According to legend, the goddess Xihe can bathe in the sun.

And their Xihe satellite obviously does not have such technical level now.

The Xihe satellite's orbit around the sun is an ellipse with a large eccentricity.

The sun is at one focus of the ellipse.

"When satellites are close to the sun, they are even less than 10 million kilometers apart."

Zhang Xingyang said worriedly:

"Recently, the sun is in an active period, and the solar wind is violent, which will cause serious damage to our mirror reflective shield."

The Sun as a main sequence star.

On a cosmic scale, the activity is not dramatic.

Compared with those giant stars whose mass is dozens or hundreds of times.

It is like a slowly flowing river, while those giant stars are like huge rivers with turbulent waves.

It is precisely this kind of peace that allows thousands of kinds of life to be born on the earth.

But hidden beneath this peace.

The sun still has unimaginable power.

It was just like Zhang Xingyang remembered the sudden super electromagnetic storm.

Super strong electromagnetic radiation even allows the aurora to spread to temperate zones!

This is a disaster that is rare in millions of years.

It directly destroyed all electrification equipment in the entire Western Hemisphere.

But to the Sun, it's just like a sneeze.

It doesn't lose even one millionth of its mass.

To say it was sneezing is actually an exaggeration.

Taking humans as an example, a sneeze consumes about 5 grams of material.

For a 50KG human being, the mass ratio lost in one sneeze is about one ten thousandth.

One ten thousandth of the mass of the sun is equivalent to 33 Earth masses.

Definitely enough to turn the earth into powder.

Not to mention humans who are nothing more than parasites on Earth.

"The charged particles of the solar wind will indeed have a greater impact on our mirror shield."

The mirror shield itself is used to protect against the impact of various charged particles in the solar wind.

Geng Bo also calmed down again and said:

"Especially the positrons in the solar wind have a huge corrosive effect on the mirror surface."

Nuclear fusion inside the sun fuses hydrogen atoms into helium and generates two positrons.

Although most positrons will collide with ordinary electrons, releasing a large amount of energy, and two mu photons.

But there will still be a small amount of positrons that break through the high-pressure constraints inside the sun and appear on the surface of the sun.

And along with the solar wind, it escapes into interstellar space.

The density of positrons in this part is extremely low.

A small amount of positrons will also be annihilated when encountering matter in interstellar space.

Therefore, before the development of radio telescopes, humans rarely found this on the sun.

However, the position of the Xihe satellite is too close to the sun.

It has crossed the orbit of Mercury.

A large number of positrons hit the mirror shield of the Xihe satellite before they could be annihilated.

The annihilation process will generate a large amount of energy and cause extreme damage to the mirror surface.

Because the entire mirror shield is actually less than two millimeters thick.

"However, the elliptical orbit we use can reduce this impact to a very low level."

Geng Bo said immediately.

The elliptical orbit means that the Xihe satellite will only be relatively close to the sun for a short period of time.

During this period of time, a large number of positrons will be hit.

"Let's take a look at the detection results of the first solar grazing first."

"No matter what happens in the future, we must obtain enough data this time."

Zhang Xingyang returned the conversation to this exploration mission.

The current mirror shield is still in normal operation and can effectively block the solar wind from eroding the equipment on the Xihe satellite.

"Look, the Coronal Dynamics Imager has been started!"

Zhang Xingyang's eyes were fixed on the big screen, slowly advancing the progress of the equipment.

The Coronal Dynamics Imager is a high-precision equipment developed by the domestic Institute of Optics and Mechanics with great efforts.

It also has the highest requirements for satellite attitude control accuracy.

Day direction (roll axis direction): Attitude pointing accuracy requirement is ≤45arcsec, attitude stability requirement is ≤3arcsec/30s.

In the hall, everyone was quietly waiting for the Xihe-1 satellite to transmit data back to the country.

The Coronal Dynamics Imager takes about thirty minutes to take its first picture.

Moreover, the Xihe-1 satellite is currently 7 light minutes behind the Earth.

This is a distance that even light takes seven minutes to travel.

"The first photo has been sent back!"

Nearly forty minutes passed quickly.

After going through intense transcoding and other operations, a super large picture was finally presented.

Coronal eruptions reaching tens of thousands of kilometers high are enough to burn through the entire Earth.

Now it is in front of everyone's eyes.

"After this step is completed, our third-generation power generation satellite can officially enter the development stage."

Zhang Xingyang breathed a sigh of relief and said to Geng Bo beside him.

The third generation of power generation satellites is completely different from the previous two generations.

It is actually closer to the imaginary product in science fiction-Dyson Cloud! (End of chapter)
