National Space Science Data Center

NSSDC is the nation-level space science data center which recognized by the Ministry of Science and Technology of China. As a repository for space science data, NSSDC assumes the responsibility of the long-term stewardship and offering a reliable service of space science data in China. It also has been the Chinese center for space science of the World Data Center (WDC) since 1988. In 2013, NSSDC became a regular member of World Data System. Data resources are concentrated in the following fields of space physics and space environment, space astronomy, lunar and planetary science, space application and engineering. In space physics, the NSSDC maintains space-based observation data and ground-based observation data of the middle and upper atmosphere, ionosphere and earth surface, from Geo-space Double Star Exploration Program and Meridian Project. In space astronomy, NSSDC archived pointed observation data of Hard X-ray Modulation Telescope. In lunar and planetary science, space application and engineering, NSSDC also collects detection data of Chang’E from Lunar Exploration Program and science products of BeiDou satellites.

国家空间科学数据中心（NSSDC）系经我国科学技术部认定的国家级空间科学数据中心。作为空间科学数据的存储库，NSSDC承担着对中国空间科学数据的长期监护职责，并提供可靠的服务。自1988年起，NSSDC已成为世界数据中心（WDC）空间科学的中国中心。2013年，NSSDC成为世界数据系统（World Data System）的常规成员。数据资源集中于以下领域：空间物理学与空间环境、空间天文学、月球与行星科学、空间应用与工程。在空间物理学领域，NSSDC负责维护来自地球空间双星探测计划和子午工程的中高大气、电离层及地表的空间观测数据和地面观测数据。在空间天文学领域，NSSDC存档了硬X射线调制望远镜的定点观测数据。在月球与行星科学、空间应用与工程领域，NSSDC亦收集了嫦娥月球探测计划中的探测数据以及北斗卫星的科学产品。
