空间科学大数据的机遇与挑战

Space science is a discipline with high innovation orientation and frontier intersection. Countries all over the world attach great importance to it and have promoted a series of strategic planning and major programs. The age of big data in space science has arrived. In this study, the main trends of big data development in space science are expounded. Specifically, space scientific data volumes are exploding, data storage and management are valued, the scientific research paradigm is shifting, big data technology and tools are booming, the intelligent application is budding and a benign research ecosystem of big data has been formed. Based on the development requirements and national strategic planning, this study analyzes the specific challenges and development opportunities of big data in space science. An all-out efforts should be made, from the perspectives of data sharing, data long-term storage, big data infrastructure construction, disruptive technologies breakthrough and research ecosystem construction, to promote the open and sharing of scientific data, to expand intellectual innovation and scientific and technological output, and to create a new era for the development of space science.
