On April 24,1970,China successfully launched its first man-made satellite,DFH-1. It was a milestone in China's space history,making China the 5th country capable of independently developing, launching and operating satellites following the former Soviet Union, the United States,France and Japan. Since then China's satellites have been launched into space one after another and benefit mankind due to their advantages. Over the past 40 years,China 展开更多
