While the use of satellites for classified reconnaissance gave additional impetus to the US space program, those behind the classified activities were resistant to allowing civilian Earth observation. Nevertheless, in 1965, NASA started exploratory research on remote sensing of Earth resources, with contracts granted to the US Geological Survey and the Army Corps of Engineers for research using sensors flown in NASA aircraft (Mack p 237).
