Our Planet Our Home An Earth Day Perspective

We are all connected to and by Earth --- whether it's the trees and plants that give us the oxygen we breathe, the snow-capped mountains that provide the water we drink, or the breathtaking geophysical forces that shape the land beneath our feet. NASA has over 20 satellites measuring the height of oceans and inland water, clouds and precipitation, carbon dioxide and much more. By understanding our changing world, we improve lives and safeguard our future.
