Abstract： The space sience development strategy and plan of major space powers have evolved in several aspects, with the new progress in science and technology achieved in recent years. Committee on Science, Space and Technology in U.S. House was established in 2011. NASA created two new mission directorates named Human Exploration and Operation, and Space Technology. Space shuttles retired in 2011 after thirty-year service, and U.S. private space flight program and Mars robotic project have made great progress. The Global Exploration Roadmap and Decadal Survey in various disciplines of space science have been issued, with the priorities of space science missions planned to be implemented in next decade ranked. European Space Agency has signed Accession Agreement with Romania, Poland, Estonia, and Hungary, which made the number of its member states up to 22, and its space science missions of different classes (L, M, S and etc.) in Cosmic Vision 20152025 have been down-selected, with the selected ones successively put into implementation. Russian Federal Space Agency and Russian space industy have been under reform since 2011. Russian space activites carried out before 2020 were planned with its national plan issued in 2013, according to which Russian space budget will increase substaintially. As to Japan, Space Strategy Office was created in Japan Cabinet Office in 2012 to supervise overall space programs, which have continuously made breakthroughs. India has taken a rapid pace in Moon exploration and Mars program, and its space programs budget has increased continuously. Several features of internantional space science development strategy stand out and can be summarized as follows:investment in space science remains continuously stable, and major space powers have revised their space science plans or issued new ones;new space departments have been created or reformed to enhance efficiency;private sectors were encouraged to be involved in space flight activities to promote economic benefit;international cooperation has been further expanded. Space science plays a significant role in the whole national stategy. It is expected that Chinas space science plays a more and more important role in implementing our national innovation-driven development strategy.

Abstract： The earth is the cradle of mankind, but human beings cannot live in the cradle forever. The launching of the first man-made satellite in 1957 by USSR indicates the kick-off of space era, which also brought up a new discipline of science Space Science. Though young as it is, space science mainly focuses on the old questions such as the origin and evolution of universe and life, the evolution of solar system and its planets, the laws of solar activity, and the evolution of the planet earth, the answers of which have been sought by human beings for thousands of years. The development of space era enables human beings to have access to space. With no disturbance and shielding of the earth atmosphere, the universe could be viewed and explored in a new way. Space science, usually taking satellites or spacecraft as platforms for observations and experiments, studies the phenomenon and laws of physics, astronomy, chemistry and life, etc. in the universe. In recently rough 60 years, through space scientific exploration and research, plenty of significant discoveries and breakthroughs had been made and our knowledge of universe had been transformed, so that the textbooks have been rewritten periodically. Meanwhile, the development of space science is close-related to the development of space technology. With the implementation of space science missions, the space and related technologies have been advanced greatly, many new fields have been opened up, and several generations of young people have been inspired to seek the dreams of new frontiers for science and technology. Space science, which has been in a race in developed countries, plays an important and strategic role in national development, and is remarked as the generator of wealth, driver of innovation, and the source of new theory and knowledge.

Abstract： After the half-a-century development, space science has not only explored and settled new frontiers, expanding humans understanding about nature and human itself, but also lead the rapid development of space and related technologies, and also brought about a number of innovative applications, which has been advancing national scientific, security, economic and social interest and human life quality. China has laid a certain foundation in space science research through 50 years of development. In 2011, the go-ahead of Strategic Priority Program (SPP) on Space Science marked that China's space science had entered a new stage. With an analysis of domestic space science status as the beginning, the paper poses the scientific questions to be addressed by Chinese space science community in 20162030, which is a) how did matter originate, how does it evolve and move? b) whats the relationship between the solar system and human beings? Besides, The Chinese space science strategic goal is proposed, i.e. to make great scientific discoveries and achieve innovative breakthroughs by a series of scientific satellite programs and missions in frontier scientific fields, such as the formation and evolution of the universe, the exploration of exoplanets and extraterrestrial life, the formation and evolution of the solar system, solar activities and their impact on the earths space environment, the development and evolution of the earths system, new physics beyond the current basic physics theories, the law of matter motion and the law of life activity in space environment, etc;and to drive the great-leap-forward of aerospace and related high technologies. In addition, the paper also proposes the space science programs and missions through 2030, and probes into the supporting technical capability. Through the implementation of a series of space science programs and missions, it is expected to make due contribution to Chinas economic and social development and humans civilization.
