Technology: breaking the hegemony that monopolizes the world

The engineer wiped the cold sweat from his forehead, and said in a slow tone: "The coordinates are confirmed, yes, they have been confirmed. There is also a first draft of the predicted orbit formula, but we probably don't have satellites at a suitable distance to implement this plan."

"Um?"

This answer made SpaceX's director, Musk Krypton, narrow his eyes slightly, "Is there still a short distance between our satellites?"

The engineers looked at each other, and finally an old engineer who had joined SpaceX since its inception explained: "Before we encountered a geomagnetic storm, as many as 40 of the 46 Starlink satellites we launched in this orbit and area were damaged, so at present The available satellites have not been able to be drawn for operations.

However, according to the orbit of the Kyushu Science and Technology aircraft, after waiting for another hour, our three communication satellites will be able to change their orbits and hit it head-on. "

"Geomagnetic explosion? The geomagnetic explosion five years ago caused us to lose 49 satellites. Including the previous geomagnetic explosion, we lost a total of 89 satellites!?"

Aaron Muskry asked with an exaggerated expression of shock, but the old engineer at the scene did not change much in his expression, and he still explained smoothly: "Yes, the problem of the geomagnetic explosion, the foundation of the launch site, and There's maintenance programs for comm satellites, and so on that have cost us hundreds of satellites.

If we don't expand the team and increase the maintenance service mechanism, there will be more satellites that will not work properly in the future. "

Expand the team, increase maintenance services?

Hearing these two proposals, Mars immigration pioneer and free user of tram patents, Maskryp shook his head.

"SpaceX's current team size is already the top-level team of Blue Star, and the number of satellites sent by Kyushu Technology to the sky is not half of ours.

I think you should develop a more efficient and concise system program to help these satellites increase their service life. Xia Wei can compress 30% of the code, can't you?

Or are you unwilling to work overtime for the project? "

If it weren't for the consideration of the organization behind SpaceX and the salary of himself and others, some engineers on site would have wanted to leave long ago.

For safety reasons, the Chinese space station has implemented preventive collision avoidance controls on Starlink satellites.

At this very moment, Li Jian, chief engineer of Kyushu Science and Technology Aerospace Project, the command center of Kyushu Science and Technology Southwest Launch Center, was acutely aware of a problem.

How can there be more satellites in this orbital region than our planning predicted?

He made a zoom-in gesture with his right hand to rebroadcast real-time images of the orbit that the spacecraft carrying Ergou is about to pass, and zoom in on some satellite patterns that can be photographed.

Afterwards, Li Jian took a deep breath and sighed: "When SpaceX's Starlink satellite maneuvered to the orbital altitude of our Daxia space station several times, in order to avoid unnecessary collisions, the Tiangong space station had to make two emergency orbit adjustments.

SpaceX has launched nearly 5,000 satellites, which is simply 5,000 large pieces of space junk, which is too shameless. "

Zhan Kunhu, the person in charge of the satellite R\u0026D and manufacturing department under the Kyushu Science and Technology Aerospace Department, heard the sigh of the chief engineer from the side, and a surge of anger rose in his heart.

"It's more than shameless, it's just selling swords! SpaceX plans to launch 42,000 satellites!

At the beginning, this project was resisted by many experts and scholars in the world, but Maskr lobbied all parties and even came up with a solution. He said that Starlink satellites will have a built-in "autonomous avoidance system", using the NORAD database to guide satellites to automatically avoid all spacecraft.

But what happened?

According to the incomplete statistics of our department and some international organizations, more than half of the close contact events between satellites that have occurred since Xiayin ephemeris 1019 were caused by Starlink satellites.

In addition to our space station in Daxia, many spacecraft of other Guo Jiahe organizations have also been threatened by Starlink satellites.

For example, the European Space Agency's wind monitoring satellite Aeolus almost collided with SpaceX's Starlink satellite. If the staff of the space agency hadn't discovered the danger in time and changed the satellite orbit urgently to avoid the collision, otherwise The wind detection satellite will be destroyed immediately. "

When it comes to the bad things about Starlink satellites, as an expert in satellite research, Zhan Kunhu is full of anger.

It even gave a conclusion: "The 'autonomous avoidance system' built into the Rausch Starlink satellite is more like a remote control system, which specifically controls the Starlink satellite to hit other satellites."

When other experts and engineers in the command center heard this, their faces were filled with anger.

Looking at the company's support now, it is obvious that its own aerospace department has gradually become the first department in Kyushu Technology Company, and even the Titan Star department has to provide assistance to its own department.

If the progress of some projects is really slow due to the Starlink satellites in the future, or even a certain score drops in the eyes of the company's senior management, it will not be worth the candle.

Li Jian listened to Zhan Kunhu's anger, but his expression was still calm.

"Although the Tiangong space of our Daxia seems to be static, in fact it has been maintaining a high-speed motion of 7.68 kilometers per second. Under normal circumstances, it only takes 90 minutes to circle the blue star.

And it will take about 100 minutes for our spacecraft to carry Ergou this time.

When the relative speed difference is relatively small, two spacecraft on the same axis and moving in the correct direction can make contact, just like the refueling of fighter jets in the air, and the docking mission between the space station and the space shuttle, it will not be too big problem arises.

But if this speed exceeds the safe threshold. It is extremely easy to cause extremely serious consequences. For sophisticated satellites and other spacecraft, even an ordinary collision is enough to destroy the stability and integrity of the equipment structure, directly affect the normal operation of the equipment, and even cause equipment damage. .

At an important meeting before, experts from Daxia Aerospace Group revealed to us that the two approaches of the Starlink satellite had obvious control operations, and they judged that they were all man-made.

After the first unsuccessful touch, the second operation of the Starlink satellite was more dangerous, and it continued to change orbits several times. As a result, our Daxiagong space station was completely unable to evaluate and predict its movement direction and error, and could only implement emergency collision avoidance. , leaving the established track. "

The staff who can enter this command center have a considerable amount of knowledge in the field of aerospace, so they all know that Maskk has bad intentions.

In the chief engineer's narration, some new employees planted a seed of distrust and even anger towards the Starlink project in their hearts.
