2065438+At about 18 on September 22, 2007, the Tianzhou-1 cargo spacecraft was derailed under control.
At this point, the second step of China's manned spaceflight project has been completed, striding into the "space station era".
In recent years, China's manned space flight has successively achieved a series of achievements, such as the first application flight of Shenzhou-10, the first flight of Long March-7, the stable operation of Tiangong-2, the mid-term stay of Shenzhou-11 astronauts, the docking of Shenzhou-11 and Tiangong-2, and the smooth filling of Tianzhou-1 propellant.
At the press conference held by the State Council Press Office on June 4, 20 19, Wu Yanhua, deputy director of the National Space Administration and deputy commander of the lunar exploration project, said: China will continue to implement the lunar exploration project, break through the automatic sampling and returning technology of extraterrestrial objects, and launch Chang 'e V around the end of 20 19 to realize regional soft landing and sampling and returning, and the lunar exploration project will be realized.
The "China Height" has been refreshed again and again, which shows the sacredness and glory of national projects.
2. Jiaolong explores the ocean
As the only deep-sea manned submersible in China, Jiaolong plays an important role in deep-sea exploration.
Diving depth is a symbol of a country's deep-sea exploration ability. Among the manned submersibles used in scientific research in the world, only Jiaolong can reach the working depth of 7000 meters.
The New York Times published a special article on China's deep-sea investigation plan. The conclusion of this article is that the deep-sea test conducted by Jiaolong submersible is an important symbol of the rise of China, just like entering outer space.
For China, which has a "blue land" of more than 3 million square kilometers, whether it can go deep into the sea is of great practical significance.
3. Single aperture radio telescope
As the world's largest single-aperture radio telescope, the completion of FAST has pushed China's astronomical research to a deeper world: it has created a new model for building giant telescopes, with independent intellectual property rights, and is considered to be able to maintain a world-class position in the next 10 to 20 years.
With the continuous overcoming of many technical problems of cable net, 12 independent innovation patents have been formed, including 7 invention patents, which greatly improved the level of cable structure engineering in China.
It will promote the development of high-tech technologies such as antenna manufacturing technology, microwave electronics technology, parallel robots and long-span structures in China.
4.supercomputers
930 million times per second! This is the floating-point operation speed of "Shenwei Taihu Lake Light".
From 2065438 to June 2007, in the latest ranking of the top 500 supercomputers in the world released by Germany, "Shenwei Taihu Light" appeared at the top of the list for the third time with this "super speed" and achieved three consecutive championships.
20 1 165438+20061October, based on "Shenwei Taihu Light", the application project of "Extended Atmospheric Dynamics Full Implicit Simulation" completed by our research team won the highest award in supercomputer application field in 20 16, and became the highest performance calculation in China.
5, the third generation of nuclear power technology
On August 6th, 20 17, the third generation nuclear power technology independently developed by China and the national major large-scale advanced PWR CAP 1400 demonstration project 1 unit main pipe bend A were completed, and the bending radius and angle met the design requirements.
CAP 1400 has been successfully developed, with independent intellectual property rights, realizing the autonomy of the third generation nuclear power technology in China, and its comprehensive performance has reached the global leading level.
