Learn how NASA observes Earth and other planetary bodies with remote sensors on satellites and aircraft that detect and record reflected or emitted energy. Explore different types of orbits, electromagnetic spectrum, sensors, resolution, data processing, and analysis.
An Earth observation satellite or Earth remote sensing satellite is a satellite used or designed for Earth observation (EO) from orbit, including spy satellites and similar ones intended for non-military uses such as environmental monitoring, meteorology, cartography and others.
Remote sensing is obtaining information about an object from a distance. Photography is a very common form of remote sensing. There are different ways to collect data, and different sensors are used depending on the application. Some methods collect ground-based data, others airborne or spaceborne.
Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Special cameras collect remotely sensed images, which help researchers "sense" things about the Earth. Some examples are:
