A Brief History of Earth Observation
The concept of earth observation dates back to the 1960s, when the first satellite, TIROS-1, was launched to study the Earth’s weather patterns. Since then, the field has grown exponentially, with the launch of numerous satellites designed to collect data on everything from ocean currents to land use change. Today, earth observation is a global industry, with over 1,000 satellites orbits the Earth at any given time.
