Today is space with you [Issue 1358]
For xichang satellite launch center, 2021 is an extraordinary year.
This year, the two launch sites of Xichang and Wenchang "two fields and one heart" went hand in hand, jointly setting an impressive record of all 21 successful missions in the whole year, and using aerospace hard power to present the best congratulatory gift for the party's centennial birthday.
The Tianhe core module soared into the sky, China officially entered the era of the space station, "Tianwen-1" landed on Mars, "Xihe" achieved a breakthrough in China's solar exploration zero, and the Long March series rocket launched more than 400 times... This year, countless astronauts have carried out relay exploration, which has achieved this unprecedented aerospace year!

Non-stop | The sky is full of stars
On January 20, 2021, the Long March 3B carrier rocket carrying Tiantong-1 03 satellite was successfully launched at the Xichang Satellite Launch Center, kicking off the prelude to the 2021 space war and a new journey for the development of China's aerospace "14th Five-Year Plan".
At 11:23 on April 29, at the Wenchang Cosmodrome, the Long March 5B Yao-2 carrier rocket carrying the space station Tianhe core module dragged a dazzling tail flame to the ground, and about 486 seconds later, the payload and the rocket were successfully separated, the Tianhe core module accurately entered the predetermined orbit, the launch mission was a complete success, and China officially stepped into the era of the space station.
At 9:22 a.m. on June 17, the Long March 2F Yao-12 carrier rocket carrying the Shenzhou 12 manned spacecraft was successfully launched at the Jiuquan Satellite Launch Center, successfully sending Nie Haisheng, Liu Boming, and Tang Hongbo into space. This is the first manned mission in the space station stage after 5 years, and it is also the first manned mission in the space station stage. At 18:48, the three astronauts were successfully stationed in the Tianhe core module and stayed in the cabin for 3 months.
At 15:10 on September 20, the earth-shaking roar resounded throughout the sea and the sky, at the Wenchang Cosmodrome, the Long March 7 Yaosi carrier rocket carried the Tianzhou-3 cargo spacecraft to soar into the sky, and after the combination of docking, the Tianzhou-3 cargo spacecraft could supply various materials needed for work and life for the subsequent astronauts stationed in the space station.
A take-off, a breakthrough, in silence, steadily leaping forward. Since its establishment 51 years ago, the center has successfully carried out more than 130 satellite launch missions, and has successfully sent more than 100 domestic and foreign satellites, such as China's first experimental communication satellite, practical communication satellite, international commercial satellite, navigation satellite, lunar exploration satellite, data relay satellite and the first large-thrust bundled carrier rocket, into space, creating the first launch of a number of "firsts" in China's space history, making China the fifth country that can independently launch a geosynchronous orbit satellite!

It has been | Forge ahead
The results will certainly not be smooth. I still remember those nights of overtime, and I still remember those moments of overcoming difficulties, all of which converge into the exclusive memory of 2021.
The hour hand is set back to May 19. At about 1 p.m., the Changqi Yaosan rocket had entered the minus 12-hour launch process. Kerosene filling, liquid oxygen filling... The launch was carried out in an orderly manner according to the regulations, and the words "normal" in the microphone came from time to time, and each astronaut performed his or her duties, busy but not chaotic.
At 21:40 that night, less than 3 hours before the launch, the data in the accusation hall of the Wenchang Space Launch Site showed: "A pressure value parameter is abnormal!" Suddenly, the scene fell silent... Huge rocket, huge system, where is the leakage point? Which part of the Rockets went wrong? Everyone did not have time to think much, did not care about rest, quickly organized problem troubleshooting, and orderly advanced fault analysis.
The rear was busy all night, and the front row was equally tight. Late at night, less than two hours before the scheduled launch, it was decided to postpone the launch. The emotion of loss hung over the entire launch site, and many people felt "half cold". In fact, many people also know in their hearts that this is the result of careful research by the mission command, and it is not allowed to let the rocket carry a trace of hidden danger to the sky, this is iron discipline, the bottom line, and cannot be shaken!
At about 1 a.m. on May 20, the news of the postponement of the launch was announced: the launch mission was postponed for technical reasons. Netizens who pay attention to aerospace have left messages: "Nothing is in a hurry, we are waiting." "Understand and understand, don't take the question with the heavens." "It's okay, we want steady happiness"...
However, the busy rhythm of Wenchang personnel is still the same, and the tense troubleshooting is still continuing. For a full 9 days, after two launch delays and repeated repetitions, the workload can be imagined: 200 telephone calls adjusted the position plan 3 times, and 5 "01 commanders" went into battle together; the power system post personnel were injured and asked for help, and no one cried out and tired for 48 consecutive hours; 55 cooking staff worked in two shifts, sending more than 4,000 overtime meals to the front line every day...
At 20:55 on May 29, the earth-shaking roar resounded throughout the sea and the sky, and the Long March 7 rocket lifted the Tianzhou-2 into the air and flew into the boundless universe, and the Launch Mission of Tianzhou-2 was a complete success. The command hall resounded with unceasing warm applause, and the scientific and technological personnel were excited and hugged each other tightly to celebrate this hard-won victory.
A round of sea rising bright moon
A stone's throw away from the South China Sea
The late-night launch site was buzzing with people
Nearby, it was busy
In the distance, thousands of homes are lit
China's space industry
Ben was self-made and went through ups and downs
Get up again and again, fall down again and again, get up again and again
With self-reliance, independent innovation, unremitting exploration
To be able to break through the barriers and win the pass, to create a great cause
In the lessons of success and failure
The Xichang Satellite Launch Center was also formed
Xichang aerospace spirit and island entrepreneurship spirit
Over the years, they have gone from the Gobi Desert to the deep mountain gorges
Then to the coconut grove island, work hard together to overcome difficulties
Like those jacarandas on the space road, pure and warm
unshaken
Dream for nine days
