A view from space - Introduction to satellites Key learning points: Satellites are objects which orbit a larger body. Artificial satellites are launched for many different jobs, including telecommunications, navigation, scientific research, weather forecasting Earth Observation satellites carry sensors that collect data about Earth or atmosphere processes. These sensors are either active or passive and measure different wavelengths of energy on the electromagnetic spectrum. Satellites give us a "big picture" view our world and are really important for collecting data about the oceans.
