"You may not know that the orbital resources in Blue Star's outer space are now scarce resources. Because the orbits are all fixed lines, when the number of spacecraft and satellites in the same orbit increases, this orbit cannot continue to enter new spaceflight. spacecraft and satellites to prevent dangerous events such as congestion and collision of spacecraft in orbit.
After installing the attitude engine, our spacecraft will not deviate from the orbit. Even if an error occurs, it can be quickly corrected back to the orbit. "
During the explanation by Chief Engineer Li Jian, the director also released a schematic diagram of the orbit of the Kyushu spacecraft in a timely manner. Just like a hula hoop route around the blue star, a dog-head-shaped mark is slowly advancing on the orbit line, and Underneath it is the blue star.
“There are currently many types of attitude control engines for spacecraft and satellites, but they all operate based on three working methods.
The most basic technology is cold gas propulsion. The spacecraft is equipped with a gas storage bottle filled with inert gas. Attitude control is achieved through the reaction force generated when the gas expands and accelerates and is ejected. The initial technical difficulty is low and the cost is low, but the controllability is not good and the thrust Small. Of course, this technology currently also has an advanced system, which is the micron-level variable thrust cold air propulsion system, which can allow satellites to achieve an 'ultra-quiet and ultra-stable' state and detect gravitational waves.
The second type is the most common and widely used chemical energy working fluid propulsion device. You can think of it as a small rocket. It is used by both scientific research satellites in the last century and today's commercial meteorological, communication and commercial satellites. The propulsion device is an attitude engine.
The third type of ion propulsion first heats and ionizes the liquid fuel, and then uses an electromagnetic coil to accelerate the ions and eject them to form thrust. The specific impulse of this propulsion system is very excellent and can easily reach more than ten times that of other ordinary fuels, such as NASA's new The xenon ion thruster developed and the GOCE satellite known as the 'Space Ferrari' all use this technology.
However, this technology requires a high threshold, and although the specific impulse is excellent, it is limited by the unit power, and the thrust it generates is only a few tens of millinewtons. Relying on this system, if the spacecraft wants to change orbit, the time it takes can be as long as months. Note, so it can only be used as a power system for attitude control. It can be fine-tuned but cannot be changed at will.
Although our Tiangong Space Station in Daxia also uses ion thrusters to control the attitude of the spacecraft, the Tiangong Space Station uses a more advanced Hall thruster. The thrust is much greater than ordinary ion thrusters, so it can control the Tiangong Space Station. Carry out emergency evacuation in a short time.
With the continuous advancement of aerospace projects, our Jiuzhou Technology is also making great strides in propulsion systems. We are not only developing traditional chemical energy working fluid propulsion devices and cold air propulsion, but also developing electric and ion propulsion systems.
Of course, due to our company's rapid progress in the field of materials, solid-state energy batteries have enabled our electric propulsion system to develop rapidly. After being equipped with flexible folding solar wing panels, our solid-state energy and the 'infinite array propulsion engine' can achieve short-term It outputs a relatively objective propulsion force internally to adjust the orbit of the spacecraft. "
With Li Jian's popular science, the popularity of Jiuzhou Airlines' live broadcast room has rebounded, but what triggered a new wave of barrage craze was the emergence of a phenomenon.
Some viewers discovered that on the trajectory of the Jiuzhou Science and Technology spacecraft, there were suddenly three more flashing light spots heading towards the spacecraft. According to the schematic diagram in the live broadcast room, these three light spots would soon disappear. will hit the spacecraft.
Some viewers hurriedly launched barrages.
"Hold the grass? Boss, stop lecturing and look at the uninvited guest on the screen!"
"Ergou is still sleeping. Can he wake up and fly the aircraft?"
"Has anyone noticed that there are three small red light dots on the screen? They were not there just now. Did I see it wrong?"
"As we all know, the red light point is the target signal. If this were in the game, it would probably be the point guided by the boss."
Seeing these intensive barrages, Chief Engineer Li Jian's expression also became serious in the live broadcast.
Although there is a delay of several minutes, when the live broadcast viewers and technical staff see the same special situation, they both have their own most intuitive expressions.
At Li Jian's request, the director did not cut out the subsequent command dialogue, but only silenced the technical parameters of some key instructions.
As a result, netizens in the live broadcast room saw the real version of "news live broadcast".
In the live broadcast room, Li Jian, chief engineer of Jiuzhou Technology Aerospace Project, who was still giving a lecture, said in a calm voice: "This is SpaceX's Starlink satellite. How could it suddenly switch to the orbital altitude of our spacecraft? Why? SpaceX urgently reported the situation and stated that we had previously received permission to use this orbit, and that this orbit was not the working orbit of these three satellites, allowing SpaceX to guide the satellites to avoid our spacecraft.
Prepare to start the attitude adjustment engine and perform orbit migration. "
In the voice-over, netizens in the live broadcast room felt much more at ease when they heard the chief engineer's orderly arrangements.
But peace of mind comes, everyone is still a little speechless about the unruly behavior of SpaceX Starlink satellites.
It didn’t take long for netizens to hear the voice of a staff member from Jiuzhou Technology.
"SpaceX, a space exploration technology company, stated that Starlink has experienced a minor fault and is currently investigating the source of the fault. It expects to update the system patch in three hours.
At the same time, their engineers gave predictions that it may be due to the geomagnetic storm caused by the solar flare activity some time ago. The magnetic field of the Blue Star blocked the energy of the solar storm in the upper atmosphere and heated it, causing the atmosphere to expand and become denser, damaging some parts of the body. Communication electronic equipment.
Regarding these three out-of-control satellites, they stated that they are currently unable to control these three satellites. If these three satellites cause damage to our spacecraft, they express concern and apology, and will let insurance bear part of the losses.
When we pressed, they told us that the insured amount would be one million US dollars. "
A million dollars?
Upon hearing this number, not to mention the staff and engineers, Blue Star’s netizens laughed angrily.
"One million dollars? SpaceX sends beggars? Does Jiuzhou Technology lack such a little money?"
"It's so funny. Mr. Gu wakes up every day and there's so much money in the company account that he can't even count it. What's the use of a million dollars?"
"Jiuzhou Technology has spent hundreds of millions of dollars developing and manufacturing this equipment. I wonder if Jiuzhou Technology has purchased insurance for the spacecraft."
"Buy insurance for experimental spacecraft? You are an insurance company. You dare to open this business. If you open it today, you will go bankrupt tomorrow. Do you believe it?"
