Chapter 1267 The Return Capsule Lands

At 9:15 a.m. on August 11th in Xiayin's star calendar, 23 hours and 40 minutes have passed since the last ignition password was issued, and a whole day will pass in 20 minutes, and Ergou The "adventure work" time in outer space is 24 hours, plus the time for the JZ-404 rocket to launch the spacecraft and satellite into orbit, the time for Ergou to return to the ground is not far away.

[Dog's experimental spacecraft has soared in space for 20 hours. After completing the in-orbit space experiment, it will land at our Southwest Launch Center

Ergou's current vital signs: good]

In the content of the announcement on the Jiuzhou Science and Technology Aerospace Live Broadcast Room, not only the names of some on-orbit space experiments, but also an extremely outrageous "whip corpse" location.

The three cases where SpaceX's Starlink satellite touched the porcelain Kyushu technology spacecraft were all placed in this position, and bilingual records were made in Daxia characters and English.

The time of the accident, orbit coordinates, satellite number and other information are all recorded one by one.

Every netizen entering Kyushu Aerospace’s live broadcast room can clearly see these contents on the side screen. Fortunately, SpaceX is not listed, otherwise the Samsung crash this time will definitely fail, and instead kill the stock price.

But even so, Wall Street investors, SpaceX executives, and Maskr himself were extremely angry when they saw these contents, and many people were even so angry that they reported Kyushu Technology, claiming that these contents harmed their rights and interests !

The reason is that, although Maskr did not let SpaceX go public, he said in an all-staff meeting that "the company may not be able to list its Starlink satellite Internet business until 1025 or later in the Xiayin ephemeris."

This kind of big pie made Wall Street investors so excited that they threw a lot of money at SpaceX. Although they had besieged Muskry before and wanted to bankrupt him, these investors would not talk about it at all. Take things seriously.

In their hearts, making money is the most important thing!

But now, Kyushu Technology has once again delayed their money making, and even made them continue to lose money in the future!

Countless people, under the state of cursing, worshiping, caring, blessing, cursing, calming, etc., watched the attitude thruster of the dog experimental spacecraft adjust its attitude in the live broadcast room of Kyushu Aerospace.

"Adjust the orbit, the attitude of the spacecraft is yawed to the left relative to the forward direction, and it is in a horizontal flight state."

"Adjust the posture in place, and start implementing orbit-return separation."

"The height is correct, perform a second attitude adjustment, push back the assembly and then turn 90° counterclockwise, make the propulsion cabin forward, perform return braking ignition, and implement return braking."

Li Jian stared closely at his colleague Li Lun, who was No. 0 of this space mission and shouldered the heavy responsibility of command.

Although the majority of netizens could not understand these commands and instructions, they were still reading the barrage with great interest, while watching the live broadcast, and occasionally raised their heads to look at the sky outside.

Although no matter where they are at this time, it is impossible to see the Ergou spacecraft still in outer space orbit through the cover of the atmosphere.

About 3 minutes later, the dog dog spacecraft carried by Ergou entered a state of unpowered free fall and entered a semi-ballistic return orbit;

"Altitude 145 kilometers, push back and separate."

Under Li Lun's calm command, technicians manipulated the system to separate part of the propulsion module, which burned up in the atmosphere.

The return capsule where the two dogs are located starts an extremely important task, which is to eliminate the force interference generated when the two cabins are separated, find a correct reentry attitude angle, the angle between the speed direction and the local horizontal plane, and prepare for reentry. .

This angle must be precisely controlled within 1.5° to 1.7°.

call……

Many staff members of the Kyushu Science and Technology Southwest Command Center are taking deep breaths under tremendous pressure.

Because the return capsule still has a very important hurdle to pass before entering the Blue Star,

"The altitude is 90 kilometers, and the maintenance system is finally tested.

At an altitude of 80 kilometers, enter 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 stands for cut off from all, for utter isolation, unknowing.

When the return capsules of all Bluestar spaceships enter the atmosphere at super high speed, shock waves will be produced. This shock wave will cause the surface of the return capsule and the surrounding gas molecules to become viscous and burnt. This state will generate a huge amount of heat, and the heat It is not easy to dissipate, and they will naturally gather around the return capsule, forming a high temperature zone with a temperature of several thousand degrees Celsius.

The gas in the high temperature area and the molecules of the material on the surface of the return cabin are decomposed and ionized in the violent impact, and a plasma area will be formed again.

Since the plasma can absorb and reflect radio waves, any information communicated between the return capsule and the outside world will naturally be interfered, attenuated, or even instantaneously interrupt the transmission of all information.

The entire return capsule is like entering the periphery 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 introduced a sentence very succinctly: "The black barrier phenomenon has a great impact on the return capsule entering the atmosphere. The return capsule will be interrupted for three to nine minutes in the black barrier area. Communication.

Therefore, at present, our command center has been unable to communicate with 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 open the deceleration facility.

And there are observation equipment on the ground for real-time monitoring, we will not let Ergou really be alone. "

"Wow woof!"

Back in the cabin, Ergou has completely woken up.

The violent shaking and fluctuations, even if filtered by shock-absorbing equipment, still give it a shocking feeling.

In the simple cognition of dogs, this is the feeling that a terrible disaster is coming.

At this moment, a voice suddenly appeared in the return cabin.

"Wow 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 calling you the second dog?"

"Ergou, you did a great job, I will reward you with a can!"

"Ergou, this is the bone I secretly brought over from the cafeteria. There is still a lot of meat on it. Are you happy to eat it?"

"Ergou, you are about to fly into the sky, we haven't even flown up yet..."

"come on!"

"Hahaha, when you come back, we are going to play on the lawn."

...

In the internal working channel of Kyushu Science and Technology Southwest Launch Center, a voice suddenly came out: "Southwest Command Center, Southwest Command Center, this is the Daxia Anxi Measurement and Control Center, and 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..."
