Space science——a fountain of exploration and discovery

Space science is a major part of space activities, as well as one of the most active areas in scientific exploration today. This paper gives a brief introduction regarding the main achievements in space science involving solar physics and space physics, space astronomy, moon and planetary science, space geo-science, space life science, and micro-gravity science. At the very frontier of basic research, space science should be developed to spearhead breakthroughs in China's fundamental sciences.
