Engineering
Engineering is the creative application of science, mathematical methods, and empirical evidence to the innovation, design, construction, operation and maintenance of structures, machines, materials, devices, systems, processes, and organizations. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering.
Satellite
In 1971 the CIA and Air Force began designing the Keyhole or KH series of spy satellites. On December 19, 1976, the first Keyhole was launched … Their resolution was so superior that license plate numbers on parked cars could be clearly read. Further, the satellites were used to photograph Soviet spacecraft in orbit and strategic bombers in flight.
