NASA's satellites carry sensors that observe Earth to better understand the environment. These satellite sensors gather information about weather, landforms, oceans, vegetation, land use, and other things. The information is transmitted to computers on Earth.
What do satellites tell us about Earth?
Satellites provide information about Earth's clouds, oceans, land and air. They also can observe wildfires, volcanoes and smoke. All this information helps scientists predict weather and climate.
What can a satellite detect?
Satellite sensors can detect light that we can't see. The electromagnetic energy reflects off the Earth's surface and up to the satellite sensor, which collects and records information about that energy. That information is transmitted to a receiving station in the form of data that are processed into an image.
What are the three things that satellites can measure?

How do satellites help us learn about space?
Why Are Satellites Important? The bird's-eye view that satellites have allows them to see large areas of Earth at one time. This ability means satellites can collect more data, more quickly, than instruments on the ground. Satellites also can see into space better than telescopes at Earth's surface.
How satellites affect our daily life?
They allow us to make cellular phone calls from long distances. They provide us with a global positioning system (GPS) so that we know exactly where we are and we can find directions to anywhere we want to go. They circle the earth and relay weather conditions and forecasts.
What can satellites see at night?
Satellites do not have their own lights that make them visible. What you will see is sunlight being reflected off the satellite, often off the large solar arrays that provide power to the satellites.
Do satellites watch US?
In a few short decades, the movement and activities of large swaths of Earth's humans can be tracked at all times.
What are the uses of satellites?

What can satellites tell us about the ocean?
Using satellites, NOAA researchers can also more closely study the ocean. Information gathered by these satellites can tell us about ocean bathymetry, sea surface temperature, ocean color, coral reefs, and sea and lake ice. Satellites provide other services beyond just imaging the earth.
