Today is space with you [No. 1331]
In the early morning of December 14, the roaring rocket was like a giant dragon, tearing through the night sky from the depths of Daliang Mountain and soaring into the sky. China successfully launched the Tianlian-2 02 satellite with the Long March 3B carrier rocket at the Xichang Satellite Launch Center, smoothly entered the predetermined orbit, and the launch mission was a complete success.
Cast the Celestial Chain, which is a magnificent history of constellation construction. Since the construction of the Tianlian satellite system, all of China's Tianlian satellites have been successfully launched at the Xichang Satellite Launch Center. The Skylink relay satellite system plays an increasingly important role and plays an increasingly important role in China's space launches and manned space missions, and also witnesses the pace of China's space exploration becoming more and more stable and far-reaching.
The starting point of the "SkyChain" took off began in 2008. "5, 4, 3, 2, 1, ignition!" At 23:35 on April 25 of this year, China's first Tianlian satellite, Tianlian-1 01 Satellite, rushed to space under the support of the Long March 3 C rocket, opening the first step of the Long March to launch and build the "Tianlian" constellation.
From the name point of view, "Sky Chain", as the name suggests, is the "information chain in the sky", so the Sky Chain satellite is also vividly called "satellite satellite", which mainly provides data relay and measurement and control services for spacecraft, space stations, low- and medium-orbit satellites, etc., and provides measurement and control support for spacecraft launches.
"It is equivalent to moving the ground measurement and control station to an orbit at an altitude of 36,000 kilometers, which can not only provide data transmission between spacecraft under its orbit, but also build an 'information bridge' between satellites and the earth." Introduction of the leaders of Xichang Satellite Launch Center.
Self-reliance, innovation and transcendence. From 2008 to 2012, the center successively launched the Tianlian No. 1 02 satellite and the Tianlian No. 1 03 satellite, and the three satellites were networked, making China the second country in the world to have a relay satellite system with global coverage capabilities for medium and low orbit spacecraft.
In 2016, Tianlian-1 04 star successfully entered orbit and completed on-orbit testing, and achieved global networking operation with 01, 02 and 03 satellites.
When the youth are prosperous, the aerospace industry is prosperous, and if the youth are strong, the aerospace industry is strong. Chen Zheng, the 01 commander who served as the launch mission of Tianlian No. 1 04 star, after 6 years of training in the front-line post of launch testing after graduating from university, became a crucial "gold finger" of the measurement and development system at the age of 27, and became a pivotal control system commander at the age of 28...
The process of "Skylink" networking is also the process of Xichang Satellite Launch Center gradually moving towards high-density space launch missions, and the party committee of the center uses major space launch missions to build a platform for young talents to improve their ability, a stage for self-display, and a stage for growing into talents, so that more young talents can thrive in the fertile soil of the aerospace industry. Zhang Runhong, Yin Xiangyuan, Bai Chunbo, Yu Xinchen... Under the tempering of the mission, a large number of outstanding young talents have stood out, and the "post-80s" and "post-90s" have taken on the heavy responsibility and become the core force of the Xichang Satellite Launch Center.
On March 31, 2019, The 01 star of Tianlian II was successfully put into orbit. It is reported that the Tianlian-2 01 satellite is the first satellite of China's second-generation data relay satellite system, and the Tianlian-2 relay satellite system has made significant progress in mission planning, system management and business operation, compared with the Tianlian-1 relay satellite system, and the data transmission rate and multi-objective service capabilities have also been greatly improved, which can play an important role in improving the timeliness of information backhaul of medium and low orbit satellites, manned spacecraft, on-orbit operation safety and mission implementation flexibility.
The sea is born with a bright moon, and the end of the world is at this time. On November 24, 2020, Chang'e 5 pierced the sky at the Wenchang Cosmodrome in the center. During the mission, the Tianlian-2 01 satellite and the Tianlian-1 02 satellite relay cooperated to provide space-based measurement and control and data relay services, and set up an information transmission link between the carrier rocket and the Wenchang Space Launch Site in space tens of thousands of kilometers away, and dragged "Chang'e" to the moon.
On July 6, 2021, the 05 star of Tianlian-1 was successfully launched. The satellite is the new force and the last of the Tianlian-1 series of satellites, marking the successful "double ending" of China's first-generation data relay satellite and the Dongfanghong-3 platform...
A thousand years of dreams, the construction of the "Heavenly Palace". Since the launch of the space station Tianhe core module at the Wenchang launch site, China has officially entered the era of the space station. On the afternoon of December 9 this year, the first lesson of the "Tiangong Classroom" officially began, and the astronauts zhai Zhigang, Wang Yaping and Ye Guangfu of the Shenzhou 13 crew gave space lectures on the Chinese space station, which triggered everyone to watch and praise. During the live broadcast of the lecture, the picture is clear and smooth, and the communication is smooth in real time... Behind such a miracle of "heaven-earth interaction", it is also inseparable from the Skylink Relay Satellite System that the center has been launching and building for many years, and has built a powerful information exchange and transmission network integrating heaven and earth.
"It is the accurate and stable data transmission of the Tianlian satellite that has set up a data 'transfer station' for people to travel from heaven to earth, making the 'heavens and the ends of the world' that have been chanted for thousands of years become a reality." The secretary of the party committee of Xichang Satellite Launch Center said, "Serving the country and strengthening the country in space is the unchangeable original mission of Xichang astronauts, and in the future, all scientific and technological workers of the center will continue to work hard to promote the development of China's aerospace industry, and contribute more Chinese wisdom, Chinese solutions and Chinese strength to the peaceful use of space for mankind and the construction of a community with a shared future for mankind." ”
