As a spiritual treasure of the Chinese nation and an important part of the inspiring principles for the Chinese Communists, the rich and profound space spirit contains tremendous and continuous spiritual strength. It is permeated with the core traits such as patriotism, dedication, self-reliance, and self-improvement, which develops from the spirit of atomic and hydrogen bombs, missiles, and man-made satellites as well as the spirit of manned spaceflight to the spirit of lunar exploration and the spirit of Beidou navigation in the new era. The space spirit, with its deeply-rooted origin, is forged by the people in practice, and it has reached broad consensuses and exerted far-reaching influence with the endorsement and vigorous advocation by the CPC Central Committee. In the continuous enrichment, it is transformed into the achievements of the space industry by practice, is connected into a spiritual system that bridges the past and future and keeps pace with the times across time and space, and leads the mainstream value of society. The rich and profound space spirit and its strength provide us with great enlightenment: We must adhere to the strong leadership of the CPC, stay true to our original aspiration, and be determined to serve the country. We must boost our ambition, integrity, and assurance with firm self-confidence, self-strength, and self-reliance. We must properly use Wuli-Shili-Renli (WSR) system approach and respect knowledge and talents. We must grasp the laws and trends of development, seize the mainstream of current times, and embrace the world. Guided by the rich and profound space spirit, the dream of building China’s strength in space will come true in the future.
