– The first Keyhole satellite was launched in 1960 as part of a classified program.
– These satellites have played a crucial role in national security and surveillance.
– Keyhole satellites have advanced imaging capabilities and can capture high-resolution images of Earth.

Keyhole Earth Observing System (KEOS)
– The Keyhole Earth Observing System (KEOS) is a proposed satellite constellation.
– It aims to provide real-time monitoring of Earth’s environment and climate.
– KEOS satellites would collect data on weather patterns, natural disasters, and environmental changes.
– This information can be used for scientific research, disaster management, and resource planning.
– The development of KEOS is a collaborative effort involving multiple countries and space agencies.Sources:
