What is the significance of the success of the first mission of China Space Station?
Today 18: 00, the Long March 5 B carrier rocket developed for China's manned space station project, carrying a new generation of manned spacecraft test ship and flexible inflatable cargo return cabin, was ignited and lifted off at Wenchang Space Launch Site in China! The first flight mission was a complete success!
At the online press conference held that night, Ji, assistant director of the China Manned Space Engineering Office, said that the success of this mission ushered in the "third step" of the development strategy of manned space engineering, which opened the prelude to the on-orbit construction of the space station and laid a solid foundation for the subsequent launch of the core module and experimental module of the space station.
According to the plan, China Space Station will be completed around 2022, and it is planned to carry out 12 missions. Ji said that after this mission, China will also carry out the 1 1 mission, and launch the Tianhe core module, the candlestick experimental module and the experimental module successively to assemble and build the basic configuration of the space station in orbit; Four Shenzhou manned spacecraft and four Tianzhou cargo spacecraft were launched to carry out crew rotation and cargo replenishment for astronauts.
Future mission "The future 1 1 mission is a high-density launch mission, full of a lot of new technologies and challenges." Zhou Jianping, academician of China Academy of Engineering and chief designer of China's manned spaceflight project, said that China will launch a manned spacecraft, a cargo spacecraft and three different parts of the space station. The rockets carrying out the mission include the Long March II F manned launch vehicle, the Long March VII launch vehicle and the Long March V B launch vehicle, which greatly increase the launch frequency and mission complexity. Facing the intensive launch mission, Zhou Jianping said, we should constantly innovate and change the traditional production mode. "There must be a new research and development model that adapts to this kind of launch and on-orbit management in order to achieve the goal of being more efficient, reliable and safe. This will also be a wonderful experimental class. 1 1 The completion of the mission will mark the official completion of the China Space Station. "
Ji revealed that at present, the core module of China's space station has completed the final assembly of prototype products, the sky experimental module and the dream experimental module are undergoing initial prototype development, and the space science application load has been transferred to prototype development one after another; Astronauts who have performed four missions in the construction stage of the space station have been selected and are undergoing mission training; The selection of the third batch of preparatory astronauts in China will also be completed around July this year.
