Describe the scene when the rocket was successfully launched.

At dawn, there was a tense fighting atmosphere in the rocket launching site. The long-awaited launch vehicle test is about to begin.

The tall launch tower stands on the launch site, surrounded by milky white giant launch vehicles. Engineers and technicians from all disciplines made the final inspection and operation before the rocket took off, and then left the scene, waiting for the launch time with passion. ?

In the underground launch control room, the commander stared at the time indication of the electronic clock, listened to every word reported by each operator, made a decision, and issued the password: "Ten minutes to prepare" ... "Five minutes to prepare" ... "One minute to prepare" ... With the arrival of the last few seconds, all kinds of tracking and measuring equipment in the field were turned on, and recording equipment such as high-speed cameras and tape recorders were started.

"Ignition!" Order. The young operator on the launch console pressed the button calmly and decisively. There was a huge roar from the rocket launch site immediately. This sound is like a landslide, like a tsunami, shaking the earth. The huge rocket rises from the ground, slowly rises, and its tail emits brilliant flames, reaching the sky. ?

"The launch was successful!" People are blowing and watching the flying dragon, and the waves are rolling in their hearts. ?

How many days and nights, countless soldiers fought in national defense scientific research posts, and how much effort they paid for developing and launching large-scale launch vehicles! ?

Rockets are soaring in the blue sky. After a few seconds, the rocket rising vertically began to turn; After dozens of seconds, the gas discharged by the rocket condenses into smoke in the air, just like the white practice extending southeast in the sky; Finally, in the boundless sky, it gradually becomes a small bright spot, walks out of the atmosphere and disappears from people's vision. ?

However, from Chinese mainland to the ocean survey fleet, hundreds of sets of modern survey and communication equipment designed and manufactured by China are tightly "biting" the small bright spots that people can't see with the naked eye, and accurately measure, record and report the flying speed, altitude and attitude of rockets at all times. Every second, a large number of measurement data are collected from all directions to the measurement and control data exchange center. The measurement and control center connects all participating units into a tense fighting collective through various precision equipment and lines, collects and exchanges data between participating units in time, and constantly reports rocket flight data to the measuring station to guide them to accurately track the rocket; The information measured by each station and the rocket flight situation are transmitted to the planning control center and command center in the launch site area in time. Good news keeps coming: "Follow it!" "Normal work!" "The flight is normal!" ?

In the flight control center, rows of TV screens frequently exchange colorful numbers, and automatic recorders gently trace the curve of rocket flight trajectory on the display board. This curve is very consistent with the theoretical trajectory curve marked in advance. It vividly tells people that the internal instruments of the rocket work normally and the rocket flies normally! ?

After flying in space for a period of time, the rocket re-entered the atmosphere and headed for the scheduled sea area of the Pacific Ocean. Everything is all right, and victory is in sight. People are beaming. ?

The Pacific Ocean is sparkling. The survey ship and salvage ship flying the five-star red flag are neatly arranged on both sides of the rocket's scheduled landing area, just like a guard of honor. Destroyers of the People's Navy patrol around the fleet. A series of telemetry helicopters flew into the blue sky and captured its tracks with various measuring equipment on the measuring ship.

The rocket flew at high speed to the scheduled splashing sea area. ?

"Find the target!" People flocked to the deck. Keep an eye on the northwest of the fleet. Soon, a bright spot emerged from the clouds, pulling out a dazzling white light and heading straight for the scheduled sea area. The highlights are getting bigger and bigger. When there are still thousands of meters away from the sea surface, the instrument cabin with important parameters of rocket flight automatically pops out of the rocket head, opens the parachute and slowly lands on the sea surface. The rocket's head plopped into the sea, stirring up a towering column of water. When the instrument cabin fell into the water, fluorescent dyes dyed the blue sea water emerald green, floating on the ocean like a ribbon hundreds of meters long. It is colorful and beautiful! ?

At this time, a working speedboat, which had been waiting nearby for a long time, entered the landing area, such as an arrow. I salvaged the helicopter and quickly flew to the landing site. The plane arrived at the instrument cabin and circled vertically in the air 30 meters above the sea. The diver jumped into the sea along the ladder and successfully salvaged the instrument cabin in only 5 minutes and 20 seconds. The helicopter carried the instrument cabin and flew back to the flight deck of the salvage ship safely.

At this point, China's launch vehicle from China to the Pacific Ocean flew over the sky thousands of miles away, which was a complete success.

"The rocket fell into the scheduled sea area!" "Measurement recovery task completed!" The news of this victory, by measuring the powerful communication waves on board, quickly spread to the monitoring station of the motherland, to the launch site and to the capital Beijing. The fleet whistled and colorful flags fluttered, and people far away from the motherland cheered and shook hands to celebrate. ? "We won!" From the land to the sea, the troops involved in the experiment until the people of the general command suddenly applauded to celebrate the victory.
