More than  860,000 images\nof the Earth's surface, collected between 1960 and 1972, were  declassified\nwith the issuance of this Executive Order.\n\nImage collection was driven, in part, by the need to confirm  purported \ndevelopments in then-Soviet strategic missile capabilities.  The  images\nalso were used to produce maps and charts for the Department of Defense \nand for other Federal Government mapping programs.  In addition to the \nimages, documents and reports (collateral information) are available, \npertaining to frame ephemeris data, orbital ephemeris data, and mission \nperformance. Document availability varies by mission; documentation was\nnot  produced for unsuccessful missions.", "distribution": [{"@type": "dcat:Distribution", "description": "Query and order satellite images, aerial photographs, and  cartographic products through the U.S. Geological Survey.
