On December 23, at the Wenchang Space Launch Site in China, the tall and tall Long March 7 (also known as Long March 7A) Yaosan launch vehicle pointed to the sky.
On the milky white arrow body, a bright red five-star red flag pattern is particularly eye-catching.
"Attention, 30 minutes to prepare!" The countdown password sounded in the launch site.
Deng Hongqin, director of the Xichang Satellite Launch Center and commander of the launch site area command, stared at the upcoming rocket through the large screen in the accusation building.
"The Long March 7 modified rocket, with the word'modified', indicates that this type of rocket is improved and developed on the basis of the Long March 7 rocket." Meeting the high-density launch requirements of medium and large high-orbit satellites can greatly enhance China's space access capability."
"Attention all numbers, 15 minutes to prepare!" The launch site sounded the command again.
The 01 commander Fu Yiyi, who is in charge of this launch mission, is paying close attention to the changes in the data status in front of the computer screen.
This mission is also the first time for the young man to embark on the position of 01 commander, fulfilling his dream for many years.
At 18:12, a huge roar that shook the sky and the earth reverberated through the sea and the sky, and the Long March 7 to Yaosan carrier rocket soared into the sky, leaving a dazzling light between the sea and the sky, and flew into the boundless space.
With the successful launch of the Long March 7 to Yaosan carrier rocket, the annual launch mission of the Wenchang Space Launch Site achieved a five-match victory, winning the “full house” in 2021, and the total number of launches of the two Xichang Satellite Launch Center also exceeded 20 for the first time.
On March 12, the Long March 7 modified Yao 2 carrier rocket was ignited into the air, successfully sending the test 9 satellite into the predetermined orbit.
The launch of the Long March 7 modified Yao-2 carrier rocket effectively filled the gap in China's high-orbit carrying capacity and also opened the 2021 launch mission of the Wenchang Space Launch Site.
On April 29, the Long March 5B carrier rocket dragged a dazzling tail flame up to the ground and accurately entered the Tianhe core module into the scheduled orbit. China ushered in the era of the space station.
After that, Tianzhou 2 and Tianzhou 3 set sail successively here.
Today, the Long March 7 to Yao 3 carrier rocket was successfully launched.
In the early stage of the launch, the Wenchang Space Launch Site received a message from the Meteorological Observatory that "Typhoon Rey is gradually increasing in intensity, and it may intensify into a super typhoon after entering the South China Sea."
In this regard, scientific and technical personnel have done a lot of meticulous work, and carried out special "double thinking" in response to typhoons to strengthen risk identification and quality control.
On the 20th, the rain was getting stronger and the command post decided that the rocket stayed in the factory for one more day, and the transshipment work was postponed to the 21st.
In the 24 hours, dozens of astronauts spent time with the rocket to ensure the temperature and humidity of the plant and the state of the rocket.
With the launch of the first launch rocket, the youngest space launch site in China has grown vigorously, and its comprehensive test launch capabilities have continued to rise, forming a new generation of launch vehicles with high-density launch capabilities.
