   Chapter 1408 Return Journey

【Revision】

  Anxi Haoyu Technology Headquarters Park Xinyuehu Courtyard Comprehensive Aerospace Command and Control Center.

  Wu Hao came here early, waiting for the opening of the spacecraft’s return cabin to return. It's not just him who came early, Zhang Jun, Tong Juan, and Yang Fan are all here. Zou Xiaodong went to the battery factory, not in Anxi.

  Not only them, but Lin Wei and other interested people also came to watch.

   "Ten minutes to prepare!"

   Hearing the announcement, Zhang Jun couldn't help but vomit: "Damn, how come I feel more nervous than when I launched it."

Wu Hao laughed and said, “It’s useless to be nervous. The entire return process is completely controlled by the system. Manual command control will not be activated until an emergency occurs. So, no matter how much you worry about now, it’s useless. Take a look. Right."

   "I know, but I can't help but feel nervous." Zhang Jun shook his head and stared at the big screen and said.

  Wu Hao shook his head when he heard the words, and then looked at Lin Wei again. She was staring at the picture on the big screen in a daze.

   Perceiving Wu Hao’s gaze, Lin Wei smiled at him, then looked at the external camera on the spaceship on the big screen and exclaimed: “It’s so beautiful!”

   "Hehe, when the future technology matures, I will take you up to play for a few days." Wu Hao laughed.

   "Go!" Lin Wei gave him a blank look, but she still showed a longing smile in her expression.

  "The countdown is five minutes, one minute, thirty seconds, ten seconds, five, four, three, two, one, the return cabin and the service cabin are separated!”

  I saw the external camera picture of the spacecraft service cabin on the big screen. After shaking, the return cabin detached, and then slowly moved away.

  "The return module was successfully separated, and it is re-entering the atmosphere along the scheduled return orbit."

  Papa Papa...

  In the entire command and control hall, there was a warm applause.

  "Adjust the angle of the service module, the target, the South Pacific Space Cemetery, and prepare to re-enter the atmosphere."

  At this point, the mission of the service cabin has been completed, it will adjust the re-entry angle, and then return according to the preset, which is about to start the re-entry journey.

  However, it is no better than the return cabin, and it has no recovery function. So it will decompose and burn in the atmosphere over the Pacific Ocean, most of which will be burned clean, and only a very small part will fall in the "space graveyard" area of ​​the South Pacific.

  The so-called "space cemetery" refers to an area located in the Southwest Pacific, which is called Poleof. It refers to the location on the mainland that is the farthest and most difficult to reach from the coastline in any direction. This difficult-to-reach point is abbreviated as "POI".

  Because it is remote enough, very few people are active in this area, so it naturally becomes an ideal "space cemetery". There are a large number of spacecraft that will choose to decompose and fall over this area.

  Because it is far away from the mainland, there is very little human activity, so even if the wreckage of a spacecraft falls, it will not harm humans. Of course, there is still a certain probability, but the probability of being hit by this kind of spacecraft debris is much lower than your chance of winning the 5 million lottery.

  You should know that basically every lottery has a winner, and until now, no one in the world has been hit by such a fallen spacecraft wreckage or even a meteorite.

   "The return cabin begins to enter the'black barrier'."

The so-called "black barrier" refers to the shock wave generated when the return capsule of the spacecraft enters the atmosphere at super high speed, making the surface of the return capsule and the surrounding gas molecules sticky and burning, and the temperature is not easy to dissipate, forming a temperature of several thousand. High temperature zone of degrees Celsius.

  The gas in the high temperature zone and the molecules on the surface of the return cabin are decomposed and ionized to form a plasma zone. Because the plasma can absorb and reflect radio waves, it will attenuate or even interrupt the radio communication between the return capsule and the outside world, so this phenomenon is called a black barrier.

  So after entering the "black barrier", the command and control center lost contact with the spacecraft's return cabin, and then the spacecraft flew on its own. Only after flying out of the black barrier area can we reconnect with the spacecraft.

  Of course, it is not that the return capsule is completely invisible. With photoelectric telemetry equipment and radar detection equipment, it is possible to see the return capsule descending at a high speed.

   "Mongolian Aerospace Landing Field Measurement and Control Center reported that the return module is being tracked, the telemetry signal is normal, and the flight attitude of the return module is normal."

   "Attention all units, the first landing point is estimated to be 101 degrees XX minutes XX seconds east longitude, and 42 degrees XX minutes XX seconds north latitude."

   "The first, second, and third trains began to march toward the predetermined area." After hearing the announcement, Yu Chengwu sitting in the command and control vehicle immediately grabbed the radio microphone and issued an order.

  "Car group one received!"

  "The second car group received!"

  "Car Group 3 received!"

   Immediately, the search fleet composed of off-road vehicles began to set off from various areas to the predicted landing point. Through the on-board camera, you can clearly see the situation of the fleet.

   "The drone remote control team, how is the situation now?" Yu Chengwu called.

After a short while, there was a burst of electric current and reporting sounds from the radio: "The drone remote control team reported that twelve large aerial surveillance drones have taken off and are currently flying in good condition. The drones are being debugged. , The relevant video screen is being transferred back."

   "Okay, I see the picture, continue to keep it." Yu Chengwu looked at the relevant detection pictures transmitted by some aerial surveillance drones on the big screen diagonally above, then nodded and ordered.

   "Report that the return cabin has broken through the black barrier and communication has resumed."

   "Attention all units, the second landing site is estimated to be 101 degrees XX minutes XX seconds east longitude, and 42 degrees XX minutes XX seconds north latitude."

   "The first, second, third car group, quickly changed direction and rushed to the estimated landing point."

   "Landing field report, optical telemetry equipment has found the return capsule, the appearance of the return capsule is complete, and the flight attitude is normal."

"it is good!"

  Hearing this report, Yu Chengwu and Guo Yulong couldn't help but roared in low voice.

  Next is waiting for this crucial step, everyone is holding their breath, waiting for this moment to come.

   "Landing field report, return cabin, the parachute group has been thrown out, smoothly deployed, the umbrella shape is normal, the speed of the return cabin slowed down."

  Papa Papa...

  At this moment, everyone in UU reading www.uukanshu.com couldn't stand it anymore, and they all cheered and broke down.

   "Attention all units, the third landing point is estimated to be 101 degrees XX minutes XX seconds east longitude, and 42 degrees XX minutes XX seconds north latitude."

  "The drone remote control team reported that the return cabin has been found!"

  On the screen of one of the drones, above the sky, a black dot was shaking in the screen! Then the drone monitoring screen switched to infrared mode, and there was a bright spot in the middle of the screen, which was descending downward.

   Soon, this bright spot appeared in more drone surveillance pictures, and it became clearer and clearer.

   "Attention all units, the fourth landing point will be estimated to be 101 degrees XX minutes XX seconds east longitude, and 42 degrees XX minutes XX seconds north latitude."

  It didn’t take long for a group of convoys to arrive at the designated location. Through the observation equipment on the convoy’s vehicles, the return cabin and parachute group above the sky can be seen very clearly.

  Yu Chengwu breathed a sigh of relief when he saw this, and then smiled and said: "Let the driver speed up a little bit, and we will go over."
