Associated Programs
  • DMSP The first CORONA photos in August 1960 convinced authorities that knowledge of cloud cover over Russia was necessary and could be obtained only via satellite. Since the civilian TIROS program could not yet meet the requirement, the Director, National Reconnaissance Office authorized an 'interim' effort - the Defense Meteorological Satellite Program. The satellite series continued to be updated and served into the 21st Century. More...
