National Space Science Data Center
Short description
The National Space Science Data Center (NSSDC) is China’s national repository for space science data. It provides long-term preservation and access services for space science datasets and has been part of the World Data Center system since 1988.
The repository hosts datasets related to space physics, space astronomy, planetary science, and space engineering. These include data from satellite missions, ground-based observations, and major national space programs such as the Chang’E lunar exploration mission and the BeiDou satellite system.
