Aerospace technology and other science and technology combine to

   Human conquest of nature long years, has long had a desire to soar the sky, traveling the universe. Productivity and very low level of science and technology of the times, this desire can only stay in the fantasy stage. While humans have long worked to explore and try all kinds of flying, but the realization of this desire or from the hot air balloon launch the start of the 18th century.

  Since the early 20th century after the first frame of the driving force, steerable aircraft completed a brief flight, the human in the atmosphere of the ancient dream of flight really become a reality. Through hard work of many prominent figures, aviation science and technology have developed rapidly, continuously improve the performance of the aircraft. Man has gradually made a free activity in the atmosphere, but also enhance the confidence of flying out of the atmosphere. By the mid-1950s, rockets, electronics, automatic control, science and technology has been significant progress on the basis of the first artificial Earth satellite was successfully launched, creating a human space became a new frontier of human activity.
  Development of aerospace industry in the 20th century science and technology leap in progress, the result of social production by leaps and bounds. Achievements Aerospace has a large number of new achievements in science and technology. Aerospace activities so far, although only a few humans left the Earth in this cradle of the original, but its role has been far beyond the field of science and technology, political, economic, military and even human society has had a far-reaching impact.

    Aerospace technology and other science and technology combine to create a lot of new technical approach, which directly serve the many sectors of the national economy, resulting in huge economic and social benefits. Satellite communication having a communication distance, large capacity, good quality, high reliability, flexibility, etc., has become an important means of modern communication. The early 1980s, the international satellite communications network has assumed two-thirds of intercontinental telecommunication services and almost all intercontinental television transmission services. fundamental changes happen. Satellite communications can be distributed to computer equipment connected to national or international information network, greatly to be effective computer systems.

Precise broadcasting to the public can be vast areas of direct television broadcasting, television broadcasting technology to make

  Precise communications and satellite broadcasting on a vast, economically backward country is the most economical and efficient means of communication and broadcasting. Satellite navigation caused a major change in navigation technology, to achieve the all-weather, global, high-precision navigation, used in ship navigation, marine survey, offshore oil drilling, land surveying, search and rescue and other aspects. Cloud images and other meteorological data provided by meteorological satellites to improve the accuracy of weather forecasting, especially typhoons and other severe weather forecasting has a very important role in many sectors of the national economy to significant benefits. Landsat is the quickest, most effective and most economical tool for census earth's

1. resources can be applied to investigate the underground mineral resources, marine resources, water resources, assist in the management of agriculture, forestry, animal husbandry, fisheries, monitoring natural disasters and environmental pollution, etc. . Earth resources satellites to get a return every year satellite development and launch costs about ten times.
