The scope of mankind's activities has experienced expansion from land to ocean, from ocean to atmosphere, and from atmosphere to outer space. Space technology, which emerged in the 1950s, opened up a new era of man's exploration of outer space. Having developed rapidly for about half a century, mankind's space activities have scored remarkable achievements, greatly promoted the development of social productivity and progress, and produced profound and far-reaching effects. Space technology has turned out to be one field of high technology that exerts the most profound influence on modern society. The continuous development and application of space technology has become an important endeavor in the modernization drive of countries all over the world. The Chinese nation created a glorious civilization in the early stage of mankind's history. The gunpowder "rocket" invented by ancient Chinese was the embryo of modern space rockets. After the People's Republic of China was founded in 1949, China carried out space activities on its own, and succeeded in developing and launching its first man-made satellite in 1970. China has made eye-catching achievements, and now ranks among the world's most advanced countries in some important fields of space technology. In the 21st century, China will continue to promote the development of its space industry in the light of its national situation, and make due contributions to the peaceful use of outer space, and to the civilization and progress of mankind. At the turn of the century, it is of significance to give a brief introduction to the aims and principles, present situation, future development and international cooperation concerning China's space activities.
