The impossibility of emigrating to Mars, Zhihu.

Shenzhou-12 mission is the 19 mission since the establishment of China's manned spaceflight project, and it is also the first manned mission in China's space station stage.

Shenzhou-12 manned spacecraft has refreshed the new height of China's manned space technology and achieved five "China firsts", namely, the first manned spacecraft's autonomous rapid rendezvous and docking, the first flight around the space station and radial rendezvous with the space station, the first long-term on-orbit docking, the first ability to return to Dongfeng landing site at different altitudes, and the first ability to combine heaven and earth for multiple emergency rescue.

Space has entered a new era of commercialization and become a new engine of economic development. Professor Zhong Jing from the National Security College of National Defense University believes that subversive and revolutionary technological innovation is gestating in the space field. The United States, Russia, Europe and other countries and regions are vigorously developing space Internet, space 3D printing, space laser communication and quantum navigation technology. The development of these technologies will subvert traditional cognition, and once a breakthrough is made, it will completely change our production and lifestyle. In 20 16, China launched Mozi quantum science experimental satellite and pulsar navigation experimental satellite. Once these technologies make a breakthrough, our traditional communication and interstellar navigation will be completely changed.
