The space technology was born out of the ballistic missile technology developed during World War II and it is very difficult to calculate the trajectory by manpower, which led to the birth of the world's first computer and the entry of mankind into the information age. The United States promotes the birth and development of integrated circuits in order to expand its space superiority and meet the needs of space flight. Today, goods codes can be found everywhere in supermarkets and the technology was born when Apollo used bar codes to manage spacecraft during the Apollo moon landing. . According to statistics, 80% of the more than 1100 new materials developed and used in China this year are completed under the guidance of aerospace technology. At present, there are nearly 2000 space technology achievements and used in communications, textile, oil, transportation, medical and other industries.
