Abstract: When the aim of journey to and from between space and earth is realized in the "Shen Zhou"manned spaceship engineering,the next target of Chinese manned spaceflight will be chosen carefully.According to the needs of Chinese society ,the external social and engineering system environment of space station for utilizing space microgravity mass environment and spaceflight station Provided services for docking spacecraft are discussed.There are good basis on launch vehicle,launch and retrieval bases, and monitor stations in China.As"Shen Zhou"manned spaceship is developed,it is not difficulty to develop cargo spaceship.But the astronaut system for ensuring astronaut's life and work and valuable payload system for realizing spaceflight engineering is deficient.Now it is still in research,test,training,development and demonstration phase.
