Technology: breaking the hegemony that monopolizes the world

One thousand two hundred and one satellites.

That’s 1,201 garbage sources.

The way to deal with scrapped satellites is generally to send the scrapped satellites upward to a cemetery orbit that is about 200km higher than the original orbit, so as to give up valuable synchronous orbit resources.

Satellites that have completed their missions will be abandoned there, wandering in the starry sky forever, watching over the little blue planet.

When Mars Krypton proposed the huge idea of ​​launching 42,000 communication satellites outside the atmosphere of Blue Star, allowing humans to access the Internet directly without relying on ground base stations, it was immediately touted as an Internet technology that is comparable to 5G or even surpasses 6G. Telecom operators in various countries are about to decline.

However, what no one expected is that Starlink satellites have not yet reached the network speed of 5G communication. Even though the network speed of 4G communication is better than it, its cost is higher than both 4G communication and 5G communication.

According to Mars Krypton’s idea, Starlink composed of Starlink satellites can provide low-cost Internet connection services on a global scale, even if users are in the north and south, or in desolate places such as the Brazilian tropical jungle and the Sahara Desert. , but as long as you set up a starlink receiver, you can communicate and surf the Internet just like in the city.

It is equivalent to SpaceX Interstellar Exploration Company setting up a router flying in the sky in the outer space of Blue Star to cover the entire Blue Star with WIFI wireless network. As long as people are on the Blue Star, there will be network signals and freedom to access the Internet.

So far, Starlink satellites have provided Internet access services to millions of users in Uncle Sam, Britain, Canada, Australia, New Zealand and Mexico.

While Gu Qing and Li Jian were freeing up a little space to discuss the handling of satellites in space orbit, many corporate executives and business elites on Blue Star simply couldn't care less about Kyushu Technology's moon landing, but took On his own mobile phone, he "speaks arrogant words".

"Fake! I don't want to hear what you said about satellite problems. I just want to know when I can use Starlink!"

"Finally, Watermare, I finally got through the phone call. Do you know how difficult it is to get through the phone call in this desert? If it weren't for the satellite communication for mobile phones this summer, Fake! You are SpaceX's customer service, you tell me When will the Starlink system be repaired!?"

A few years ago, when the Starlink project sent test invitations to pre-booked users, the invitation included charging standards. The estimated speed was 50Mbps to 150Mbps, the delay was estimated to be 20ms to 40ms, the terminal fee was US$499, and the monthly usage fee was US$99. , there is a reminder in the email that "the network may be disconnected."

After subsequent upgrades over the years, the download speed of Starlink satellite's Internet service can exceed 300 Mbps in places with relatively good networks.

However, after the Internet speed is optimized, the problem of network connection interruption of the Starlink system is still a long-standing problem.

According to reports, Starlink signals are more than 74% likely to be interrupted, and Starlink users "experience harmful interference" more than 77% of the time.

Some experts say this is because the frequency band of Starlink overlaps with the frequency band used by American Satellite Broadcasting Corporation for terrestrial 5G communication services. Both are the same 12GHz, which will interfere with the reception of Starlink signals.

But fearing this, Starlink also has the advantage of “free access to the Internet”.

However, today, June 9th in the Xiayin celestial calendar, after an individual malfunction occurred in the Starlink satellite, it was like a drop of ink contaminating a glass of water, and the entire system began to shut down.

No Starlink user can conduct Internet activities through their own Starlink signal receiver.

Many of these users don't care about moon landings or aerospace high-tech. What they care about is their own careers, their own project progress, and their own lives!

After the Starlink network interruption problem occurred, someone skillfully picked up his Xia Wei mobile phone, Honor mobile phone or other Xia brand mobile phone that supports satellite communication, and began to greet his own exclusive customer service and Starlink customer service.

Tens of thousands of Starlink satellites are crowded into space orbits. Never in the history of human spaceflight have so many satellites been operating at the same time.

Currently, SpaceX has not announced any effective recovery technology to recover Starlink satellites.

These satellites move around Blue Star at high speed and can fly 7.9 kilometers in one second. As long as they lose control, they can easily destroy other spacecraft in orbit.

Now, Jiuzhou Technology has taught SpaceX Interstellar Exploration how to deal with the "faulty" Starlink satellite, which is to transfer the orbit to a large blue star area and start a rapid landing.

The atmosphere will help burn away the garbage. If there are some hardware debris that is not completely burned by the atmosphere, it will eventually fall in this blue star area and will not affect ordinary people in other countries and regions.

Of course, it will not affect the homeward journey of Jiuzhou Technology’s lunar landing spacecraft and lunar exploration spacecraft.

Sitting on a special seat in the return capsule of the lunar landing spacecraft, team leader Zhou Jianwen verified his information again.

[Fingerprint verification is successful, voiceprint verification is successful, and Simon will guide you in the direction]

After checking again with the team members that there were no problems with the equipment and software programs, Zhou Jianwen took one last look at the safety belt around him.

call……

He did not look back, but said directly in the voice channel: "We are about to enter the return landing orbit, are you ready?"

Li Ying and Liu Genghong made no other moves after hearing this.

But their voices rang out in the voice channel.

"I'm ready!" X2

"Okay, let's go home!"

Zhou Jianwen took a deep breath, and then said on the public channel: "Command center, command center, this is the lunar landing spacecraft, this is the lunar landing spacecraft, I am Zhou Jianwen.

We have made preparations according to the established plan. "

Jiuzhou Science and Technology Southwest Launch Command Center.

After Gu Qing heard the astronaut's voice coming from the public channel, he immediately responded: "This is the Southwest Command Center, this is the Southwest Command Center.

Zhou Jianwen, according to data from the ground command center, the lunar landing spacecraft return module system and equipment are operating normally. Please wait for instructions and prepare to go home. "

Hearing the word "home" this time, Zhou Jianwen looked a little dazed.

The last time he wrote a will and voluntarily signed up for a four-hour rapid landing, the commander at the time also said "go home."

And after that successful landing, he did return to his home.

With the help of the company, the parents who suffered from cancer at home have recovered their health, and the children and wife are all well.

He did have a warm life at home.

But for some reason, the more stable he lives, the more flustered he feels, and he even occasionally dreams back in the middle of the night that he is still in the space station...

It was precisely under the influence of this mentality that he chose to break his promise...

"clear!"

It's still the same response as before.

Such a line of subtitles already appeared on the helmet display panel in front of Zhou Jianwen, Li Ying, and Liu Genghong.

[Thirty seconds to prepare for the return home procedure]

"Attention all systems, this is the Southwest Launch Command Center, please pay attention to all aspects of data."

[Ten seconds to prepare for the homecoming procedure]

Countdown: ten, nine, eight, seven...three, two, one!

Go home program, start!

Under the spotlight, Zhou Jianwen pressed the button to start the homecoming program on time as before.

Bang.

Although the vacuum environment of the universe cannot transmit sound, the senses of the three Kyushu astronauts still heard the sound of the rocket working in a daze.

[The return home program has started successfully, the engine array has started successfully, and the return capsule is adjusting its attitude]

[The attitude of the spacecraft has been adjusted and the return capsule system equipment is operating normally]

[Sinan reminds you that the return capsule has entered the return orbit]

Although Jiuzhou Technology's manned space missions have always maintained a 100% success rate, this is the last important step of the moon landing mission - return.

If in previous aerospace missions, science, technology and industrial manufacturing capabilities accounted for most of the success factors, then this time, there are many other special factors.

In Anxi, Daxia, Mr. Zheng watched the lunar landing spacecraft on the screen change its angle. He saw the determined faces of the three astronauts, the serious eyes of everyone at the Jiuzhou Science and Technology Southwest Launch Center, and the lunar probe loaded with lunar souvenirs. spaceship.

He did not change his gaze, but directly gave the order: "Pay close attention to all movements, increase the power of the radar by 20%, and all units should be ready at any time."

"Roger!" The person next to him immediately saluted and responded, and began to pass on the order.

What to always have ready?

A soldier is like a sharp knife. Only when you can fight can you stop the war.

At the same time, similar orders were issued in several other special places in Daxia.

Although Jiuzhou Technology is not Daxia Aerospace Group, and the astronauts who landed on the moon this time are not astronauts officially trained by Daxia, it is enough that these three astronauts are from the Yanhuang clan of Daxia.

The reporters and self-media influencers outside the Jiuzhou Science and Technology Southwest Launch Command Center, as well as the corporate elites and invited users in the observation room, all did not hesitate to express their gratitude when they saw the decisive and perseverance of the three astronauts. applause.

In the live broadcast room, netizens from all over the world who were still frantically posting barrages, when they saw the lunar landing spacecraft and the lunar exploration spacecraft changing their orbits one after another, they all tapped the keyboard in unison and encouraged: "Go home!"

"Zhou Cao, I just searched for the captain who led the team. He is really a strong man. The four-hour rapid landing record was achieved by him."

"This is a warrior! A true living legend!"

"Made, this is more terrifying than the four-hour rapid landing challenge. The return capsule at that time was returning to Daxia from the Kyushu Space Station, while the lunar landing spacecraft ran from Blue Star to the moon, and then flew back to Blue Star from the moon. Stars, at such a long distance, the test of the instruments and equipment in the spacecraft is not as simple as before.

If something goes wrong during landing, these three astronauts may or may not die without a burial place. "

"I hope that the technology of Jiuzhou Technology can ensure that these three astronauts can successfully return to the ground. Chang'e bless..."

"I was a little frightened when I drove home on the highway during the Chinese New Year. These three warriors traveled across the planet to go home. They were so fierce."

"I have a question. Did Jiuzhou Technology plan a landing location? Others have braved all kinds of hardships and finally returned to Blue Star, but Jiuzhou Technology planned the wrong landing location."

Although Gu Qing believes that there will be no problems with the spacecraft's equipment and instruments. Even on the moon, cameras and radars are monitoring the surroundings at all times to make sure that there will never be any aliens or alien bugs that will sneak into the spacecraft or destroy the spacecraft's equipment, but There was still some uncontrollable worry in his heart.

Li Jian, one of the chief commanders of Jiuzhou Science and Technology Aerospace Engineering, felt a little emotional after seeing Gu Qing's expression.

Last time during Zhou Jianwen's rapid four-hour landing, Mr. Gu looked calm and trusting. But this time, why could even a bad old man like him detect the worry in his eyes?

Not only he, a middle-aged man, but also many people in the company's aerospace department knew about astronaut Li Ying's feelings.

The reason why no one pointed out was that everyone tacitly wanted to protect this sonorous rose, and at the same time, they were also thinking about whether this heroine could surrender to Mr. Gu.

Regarding the personal issues of our CEO, many people within the company are actually concerned.

The reason is simple. After getting along with each other for these years, they all hope that their CEO can have a happy family, so that the transfer of power to the company's senior management can be smoother in the future.

It's just that Mr. Gu's emotional line is too twists and turns, it can even be said to be non-existent!

There have been so many outstanding women, but so far, none of them have touched this stubborn stone.

After the lunar landing spacecraft determined its orbit, the engine array started and began to follow the pre-designed movement orbit, and began to slowly spiral downward toward the Blue Star ground, starting from slow to fast bit by bit.

Zhou Jianwen saw Si Nan's simulated movement trajectory, and while his expression was serious, he also felt a little emotional in his heart.

This trajectory is very similar to the trajectory of my rapid landing, but the landing takes a little longer.

It is obvious that the company's engineering team has carefully absorbed research data, rather than blindly pursuing something higher and faster.

After many upgrades of artificial intelligence and carbon-based chips, their anti-interference capabilities, peak computing capabilities, and normal computing capabilities have reached the pinnacle of current technology.

It can be said that if this technology is commercialized for civilian use, no ordinary commercial company on Blue Star Ground can withstand such an era-changing technological impact.

Zhou Jianwen said to the team members in the voice channel: "Keep your breathing as steady as possible. The engineers have already made various optimizations, so don't think too much."

Li Ying has carried out many aerospace missions. After hearing this instruction, she immediately calmed down.

As for Liu Genghong, although his physique is excellent, his mental quality is still somewhat far behind the two.

But even so, there was no lingering fear in his eyes.
