At 9:15 a.m. on August 11th in the Xiayin celestial calendar, twenty-three hours and forty minutes have passed since the last ignition command was issued. In twenty minutes, a whole day will have passed, and Ergou The "adventure work" time in outer space is twenty-four hours, plus the time it takes for the JZ-404 rocket to lift off the spacecraft and satellites into orbit, it is not long before Ergou returns to the ground.
[The Dog experimental spacecraft has soared in space for twenty hours. After completing the on-orbit space experiment, it will land at our southwest launch center
The second dog’s current vital signs: good]
The announcement content on the Jiuzhou Science and Technology Aerospace live broadcast room not only contains the names of some on-orbit aerospace experiments, but also an extremely outrageous "whip corpse" position.
The three cases of SpaceX's Starlink satellites colliding with Jiuzhou Technology spacecraft were placed in this position and recorded bilingually in Daxia script and English.
The time of the accident, orbital coordinates, satellite number and other information are all recorded one by one.
Every netizen who enters the Jiuzhou Aerospace live broadcast room can clearly see these contents on the side screen. Fortunately, SpaceX is not listed, otherwise this Samsung collision will definitely fail and kill the stock price.
But even so, Wall Street investors, SpaceX executives, and Musk himself were extremely angry when they saw these contents. Many people were even so angry that they reported Jiuzhou Technology, claiming that these contents harmed their rights and interests. !
The reason is that although Mars Krypton did not list SpaceX, it said in an all-employee meeting that "the company may not be able to list its Starlink satellite Internet business until Xiayin 1025 or later."
This kind of big pie made Wall Street investors so excited that they threw a lot of money into SpaceX. Although they had attacked Mars Krypton before and wanted to bankrupt it, this group of investors would not talk about this at all. Take things into consideration.
In their minds, making money is the most important thing!
And now, Jiuzhou Technology has once again delayed their ability to make money, and may even cause them to continue to lose money in the future!
Countless people were scolding, worshiping, caring, blessing, cursing, calming, etc., watching the attitude thruster of the Dog experimental spacecraft adjust its attitude in the Jiuzhou Aerospace live broadcast room.
"Adjust the orbit, and the attitude of the spacecraft will yaw to the left relative to the forward direction, flying horizontally."
"The attitude is adjusted in place and orbit return separation begins."
"The height is correct, perform a second posture adjustment, and then turn the push-back assembly 90° counterclockwise to make the propulsion module forward, perform return braking and ignition, and implement return braking."
Li Jian stared closely at his colleague Li Lun, who was the number zero of this space mission and shouldered the important responsibility of command.
Although the majority of netizens did not understand these commands and commands, they still viewed the barrage with great interest while watching the live broadcast, and from time to time they would raise their heads and look at the sky outside.
Although no matter where they were at this time, it was impossible for them to see the Ergou spacecraft still in orbit in outer space through the cover of the atmosphere.
About 3 minutes later, the Dog spacecraft carried by Ergou entered a powerless free-fall state and entered a semi-ballistic return orbit;
"Height 145 kilometers, push back and separate."
Under Li Lun's calm command, technicians controlled the system to separate part of the propulsion module, which burned up in the atmosphere.
The return capsule where the two dogs are located begins to carry out an extremely important task, which is to eliminate the force interference caused by the separation of the two capsules, find a correct re-entry attitude angle, the angle between the speed direction and the local horizontal plane, and prepare to re-enter the atmosphere .
This angle must be accurately controlled within 1.5° to 1.7°.
call……
Many staff members at Jiuzhou Technology Southwest Command Center are taking deep breaths under tremendous pressure.
Because the return capsule still has a very important level to pass before entering Blue Star.
"Height 90 kilometers, final inspection and maintenance system.
At an altitude of 80 kilometers, entering the black barrier! "
Whoosh——
Although there was no transmission of this sound at all, countless people felt that they heard a special sound.
That voice represents isolation from everything, complete isolation and unknown.
The return capsules of all Blue Star spacecrafts will generate shock waves when they enter the atmosphere at super high speeds. This shock wave will cause the surface of the return capsule and the surrounding gas molecules to become sticky and burning. This state will generate huge amounts of heat, and the heat They are not easy to disperse, and they will naturally gather around the return capsule, forming a high-temperature area with temperatures as high as several thousand degrees Celsius.
The gas in the high-temperature zone and the molecules of the surface material of the return capsule are decomposed and ionized in the violent impact, and a plasma zone is formed.
Since plasma can absorb and reflect radio waves, any information that the return capsule communicates with the outside world will naturally be interfered with, attenuated, or even interrupt all information transmission instantly.
The entire return capsule is like entering the peripheral side of a black hole, isolated and helpless. This phenomenon is called a black barrier.
Although Li Lun did not conduct detailed science popularization for netizens, he still gave a very concise introduction: "The black barrier phenomenon has a great impact on the return capsule when it enters the atmosphere. The return capsule will be interrupted for three to nine minutes in the black barrier area. Communication.
Therefore, our command center is currently unable to contact the return capsule.
But don’t panic, the return capsule has a system that can operate independently. When it reaches the specified altitude, the return capsule will automatically turn on the deceleration facility.
And there are observation equipment on the ground for real-time monitoring. We will not let Ergou really be alone. "
"Woof woof woof!"
Returning to the cabin, Ergou had completely woken up.
The violent shaking and fluctuations, even if they are filtered by shock-absorbing equipment, still give it a shocking feeling.
In simple dog cognition, this is the feeling that a terrible disaster is coming.
At this moment, a sound suddenly appeared in the return cabin.
"Woof woof woof~"
"Wow, you bark so loudly, but you haven't grown up yet. You are not a big dog. You are the second dog we adopted. How about we call you Ergou?"
"Ergou, you did a great job, I will reward you with a can!"
"Ergou, these are the bones I secretly brought from the canteen. There is a lot of meat on them. Are you happy to chew them?"
"Ergou, you are about to fly into the sky. We haven't flown up yet..."
"come on!"
"Hahaha, when you come back, we are going to play on the lawn."
…
In the internal working channel of Jiuzhou Technology Southwest Launch Center, a voice suddenly came out: "Southwest Command Center, Southwest Command Center, this is the Daxia Anxi Measurement and Control Center, this is the Daxia Anxi Measurement and Control Center.
The radar tracking is normal, the telemetry signal is normal, and the flight attitude of the target module is correct.
Repeat..."
