"Three steps" are about to be realized, and China Aerospace is expected in the future!

CCTV News: Today (September 21) is the 30th anniversary of China's manned aerospace project. In the 30 years since the implementation of the Chinese manned aerospace project, in accordance with the "three steps" development strategy of the central government, several generations of astronauts have continued to struggle and overcome difficulties, and successfully completed the first two steps. Realize the "three -step" strategic task goal.

On September 17th, Shenzhou 14 astronauts Chen Dong, Liu Yang, and Cai Xuzhe closely collaborated to successfully complete the outlet activities, further inspecting the ability of astronauts and small robotic arms to work, verified that the air gates and air gates of the Tiangtian experimental cabin and The functional performance of supporting equipment related to the outlet event is the seventh out of the space offices of Chinese astronauts in space.

Astronaut Chen Dong: The vast universe of the Xinghe has witnessed the changes in the China Space Station with us, which is inseparable from the hard work of all astronauts. There is a home in the world, you and I go to a dream, build a family for dreams, and keep the family for dreams. Bless the China Space Station, bless China for aerospace, and wish our motherland.

Establish a "three -step" development strategic aerospace person to continue the struggle

In order to fulfill the Chinese space home of the Chinese people, the scientific and technological workers of China Manned Aerospace Engineering have been struggling for 30 years. On September 21, 1992, the central decision -making implementation of manned aerospace projects determined the development strategy of "three steps" in the "three steps" of manned aerospace, namely: the first step, launching the manned spacecraft, and building a preliminary trial -manned spacecraft Project, carry out space application experiments; step 2, break through the aerospace officer's outlet activity technology, space aircraft meeting and docking technology, launch space laboratory, solve a certain scale, short -term people care for space application issues; third step, build space stations , Solving a large -scale, long -term care of space application issues.

The manned spacecraft successfully launched the "first step" perfectly realized

In November 1999, the Shenzhou -1 test spacecraft successfully completed the launch and recycling, and the Chinese manned spacecraft technology achieved a major breakthrough. In October 2003, Shenzhou 5 sent the first flying space clerk Yang Liwei into space and returned safely, making my country the third country in the world to control the manned space technology. In October 2005, Shenzhou 6 carried the manned spacecraft to send two astronauts to space. At this point, the "first step" task of Chinese manned space is perfectly achieved.

A number of technologies have achieved a breakthrough "Step 2" full ending

In September 2008, Shenzhou VII flying spaceflight, achieving astronauts out of the cabin, successfully completed a number of technical experiments. In November 2011, Shenzhou -8 and Tiangong -1 had two spaces and no one automatically met the docking, breaking through the technology of automatic meeting and docking. The following year, Shenzhou 9, who took the three astronauts, and Tiangong -1 successfully held hands. China was successfully completed for the first time. In June 2013, the Shenzhou 10 manned spacecraft with three astronauts successfully launched and returned to landing smoothly. During the rail, Shenzhou 10 and Tiangong -1 target aircraft successfully carried out automatic and manual meetings, and carried out the Chinese astronaut space teaching activities for the first time. From June 2016 to April 2017, the flight mission of the space laboratory was formed by the Long March 7, Tiangong No. 2, Shenzhou 11, and Tianzhou -1 flight mission. At this point, the "three steps" development strategy of China Manned Aerospace Project ended in full end.

"Three steps" is about to realize the future of China Space Station

On May 5, 2020, the Long March 5 -carrying rocket was successful in Wenchang, Hainan, and officially kicked off the "third step" mission of my country's manned aerospace project. For more than two years to this day, my country has successfully sent the sky and the core compartment, three manned spacecraft, the test cabin and the three cargo spacecraft to the space. Nine astronauts have achieved long -term residence in the space station, and have carried out a number of scientific (trial) tests in rail science (trial), and completed 6 off -cabins.

Over the past 30 years, China Manned Aerospace has sent 14 23 -person astronauts into space. The astronauts have selected new and old mixing and matching to form a reasonable "hero group". In terms of system construction, my country already has two types of low -temperature liquid rockets, two launching grounds for different dimensions for manned space launch, and set up a relay measurement and control network with integration of land and sea bases to build a complete system landing field system. In the future, in the future, in the future, in the future, in the future A new generation of manned spacecraft will also be developed.

China Space Station Construction will be completed this year

At present, the Mengtian Experimental Curm and the Long March 5 Yao -4 Launar Rockets have entered the Wenchang Aerospace launcher in Hainan for the assembly testing work. This year, it will be officially transferred to the stage of application and development.
