This is the seventh time that shenzhou spaceship flew into space and the third time that China people landed in space.
After Yang Liwei realized the Chinese dream, Fei and Nie Haisheng entered the orbital module to conduct space science experiments, today, three China astronauts Zhai Zhigang, Liu Boming and Jing Haipeng shoulder a brand-new historical mission-according to the plan, they will walk out of the module during this space flight.
China people will leave their footprints in space for the first time-this invisible footprint will surely be the most unforgettable step and will be remembered by the Chinese nation forever.
How far is the dream, how far can the pace of progress go. From 1992, when the manned spaceflight project started, to 1999, when the Shenzhou-1 experimental spacecraft was launched, and from Shenzhou 5 to Shenzhou-6, after a series of breakthroughs from dream to reality, China's manned spaceflight once again achieved a major leap.
Realizing spacewalk is a historic step for any space power in the world.
It is the astronaut's extravehicular maintenance that enables scientists to still enjoy the valuable resources provided by the Hubble Space Telescope launched in April 1990. The Mir space station with a design life of five years has been in service for 10 years, and more than16,500 scientific experiments have been carried out. This miracle is inseparable from the astronauts' continuous extravehicular maintenance ... The realization of spacewalking is a landmark breakthrough in any country's manned spaceflight process: it means that astronauts can independently leave the cabin to maintain high-value spacecraft.
The International Space Station under construction needs the participation of astronauts in space. In the "return to the moon" and further deep space exploration, it is essential for astronauts to walk in space.
Astronauts' extravehicular activities are technically difficult and risky, and they face unprecedented challenges in technical research, product development, astronaut training and mission organization and command. Because of this, since the Soviet astronaut leonov first set foot in space on March 8, 1965, only the United States and Russia have complete technology and experience of extravehicular walking since the spring and autumn period of 43 degrees.
However, as Zhou Jianping, the chief designer of China's manned spaceflight project, said, the Chinese nation, striding forward on the road of realizing its dream of flying for thousands of years, has the courage to meet such challenges.
If the astronauts leave the cabin and walk smoothly, the next step of Shenzhou flight will be the rendezvous and docking test of the spacecraft. Then develop a space laboratory with short-term manned and long-term autonomous flight in orbit with a certain application scale, and then develop a long-term manned space station.
The glory of reality never begins with great dreams. From GPS navigators in fishing boats and taxis to satellite radio and television in almost every household, from weather forecast and information network to "space rice" and "space vegetables" on the dining table ... Today, we have lived in an era when the fruits of "space civilization" are widely used.
Space not only provides us with high resources, microgravity resources, ultra-high vacuum resources, unlimited energy and material resources, but also provides us with vast space resources, which can even open up endless living space and create a new way of life for us. ...
However, human exploration and development of space has just begun. Even if the historic breakthrough of extravehicular walking is successfully achieved, there are still countless mysteries waiting for us to decipher in the vast universe.
Glory and dreams are always closely linked. As the first nation with a dream of flying, when it was still hungry, it turned the dream of "two bombs and one satellite" into a brilliant reality. We have reason to believe that with the rise of a new wave of space exploration, it is time for the Chinese nation to benefit mankind with its flying wisdom.
Shenzhou VII, proud of you.
