As the speed and height of the rocket continued to improve, it soon disappeared into everyone''s eyes, so everyone looked at the rocket flight animation in the control room.


    At the same time, because the height and speed of the rocket have reached very high, each military base or military radar station inside or outside the province also found the slowly rising rocket, and detected the attitude and flight direction of the rocket in real time.


    However, in fact, at this time, the rocket has already flown out of the coastline and is already over the coastal waters of China. After all, the linear distance between the rocket launch pad of Tiangong technology and the coastline is only 10 kilometers. At this time, at the speed of hundreds of meters per second, it won''t take long to fly over the coastal waters.


    Of course, even in this way, the military does not relax at all. After all, even in the offshore sea, there are a large number of ships sailing. Even if the rocket flies over the high seas, it is not necessarily safe. However, fortunately, when the rocket flies over the high seas, the flying altitude and speed of the rocket are very high, even if there is something wrong, Rockets will definitely be simplified and blown to pieces at the first time.


    Therefore, when the height of the rocket reached a certain level, Wang Bin and the launching personnel present relaxed a lot.


    "The rocket has left the atmosphere, ready to open the fairing and release the satellite." when the rocket finally flew out of the atmosphere, the on-site commander immediately ordered.


    At the same time, under the control of the controller, the fairing of the rocket slowly opens to both sides, ready to release the satellite after the rocket reaches the predetermined orbit.


    Of course, if it is other rockets, after the Rockets leave the atmosphere, they will directly abandon the fairing, not open to both sides, just like the Rockets they launched at the launch site in the South China Sea.


    However, Wang Bin''s improved one by Tiangong technology is different. Because Tiangong technology wants to recover the rocket as a whole, after breaking through the atmosphere, it does not directly abandon the fairing, but plans to recover it together with the fairing when recovering the rocket.


    Of course, retaining the fairing also plays a very important role. That is, when the rocket returns to the atmosphere, because the material of the fairing is very high-temperature resistant, it can also block the heat generated by friction with the air when the rocket returns to the atmosphere.


    Not long after opening the fairing, the control room again sent the rocket status data report and new orders.


    "The rocket has reached the predetermined orbit, shut down the rocket engine and start releasing the spacecraft."


    "After the spacecraft is released, close the fairing, adjust the attitude of the rocket and prepare for re-entry into the atmosphere.


    Note that when adjusting the attitude, do not collide with the spacecraft just released. "


    However, at this time, because the rocket just flew out of the earth''s atmosphere, it is impossible to return immediately. Instead, it can start to slow down and return to the atmosphere only after the rocket has made a close circle around the earth and reached a suitable position.


    As time passed, almost half an hour later, the person in charge of the control room also issued a new order again.


    "The rocket is about to enter the designated return location. Look, it''s best to prepare for the second ignition of the rocket! Fight, and the output power is 50 percent."


    "30.29.28... 3.2.1 ignition!" with the order of the launch director, the rocket engine was successfully ignited again. Only the rocket flight rules in the control room changed. Finally, when the return trajectory of the rocket overlapped with the launch pad on the side of Tiangong technology, the person in charge directly ordered the rocket engine to shut down again.


    At the same time, the camera installed on the rocket also faithfully records the changes of the rocket''s flight attitude and flight rules at this time.


    Unlike ordinary recoverable rockets, when they return to the atmosphere, the Rockets return to the atmosphere in an upright state, but this time the rocket returns directly to the atmosphere with the head of the rocket.


    After all, the rocket not only did not abandon the fairing, but even there was an aerodynamic rudder on the rocket, which could glide in the atmosphere and adjust its attitude.


    At the same time, the rocket control center is also doing its best to collect all the data when the rocket returns to the atmosphere.


    These data will also be retained after collection, which can provide real and effective data support for the larger recoverable rockets and aerospace vehicles designed by Wang Bin and Tiangong technology in the future.


    Of course, these data are not only used by Tiangong technology itself, but also can be used as data support when officials and even other enterprises want to use them. After all, China is different from foreign countries, especially in aerospace. Of course, even so, these data will not be used unconditionally by any domestic official or enterprise, but will be provided for compensation.


    As the rocket finally entered the atmosphere, the rocket fairing began to have a huge friction with the high-altitude atmosphere, and the whole fairing began to become red. According to the sensor inside the rocket fairing, the maximum surface temperature of the fairing had reached more than 2000 degrees, and began to rise rapidly with the temperature inside the fairing.


    However, although the temperature of the simplified body and other parts of the rocket began to rise in the friction with the atmosphere at this time, it did not rise to 2000 degrees like the fairing, but only a few Baidu.


    And at this time, the speed of the rocket, also under the friction with the atmosphere, began to decline sharply. From the speed of about 2000 meters, it soon dropped to less than 1500 meters per second, and this speed is still declining rapidly.


    When the rocket reaches the middle layer of the atmosphere, the speed of the rocket is only about Mach 3, and the aerodynamic rudder of the rocket can work. That is to say, the ground can finally control the rocket through the aerodynamic rudder again.


    This greatly relieved everyone. After all, before the rocket entered the escape layer, because the rocket engine did not work, it was in a non powered situation, and because the atmosphere of the escape layer was very thin, the aerodynamic rudder could not produce any effect at all. Therefore, at this time, the rocket was most likely to lose, even if it could be controlled, When the speed of the rocket is too fast and must be controlled, if the flight attitude of the rocket is wrong, it is easy to cause the disintegration of the rocket.


    Now, the rocket has returned to the controllable range. For the ground personnel, the most difficult time has passed, and they naturally have more confidence in the successful recovery of the rocket.


    With the control of the controller, the rocket soon reached the sky over the Tiangong science and technology launch site. At this time, the person in charge gave a big order again, and the fairing of the rocket was slowly opened again. All of a sudden, the head resistance of the rocket increased, and the rocket changed its flying attitude into a tail down attitude, and with the opening of the fairing, The air resistance of the rocket also becomes greater, and the descent speed of the rocket naturally becomes slower.


    And when the rocket is only about one kilometer from the ground, the parachute inside the rocket fairing is also opened, and the descent speed of the rocket is quickly reduced to only a few tens of seconds per second.


    Finally, when the rocket is less than 100 meters from the ground, the rocket engine is ignited again. Just when the descent speed of the rocket becomes zero, the rocket has just stopped at the predetermined parking point, and the rocket fuel has been exhausted at this time.


    In other words, the smooth landing of the rocket represents the successful completion of the launch.
