Earth
Your home. Our Mission.
And the one planet that NASA studies more than any other.
NASA studies our own planet more than any other. We operate 26 missions in orbit and sponsor hundreds of research programs and studies each year. We observe our planet’s oceans, land, ice, and atmosphere, and measure how a change in one drives change in others. We develop new ways to observe and study Earth's interconnected systems and we build long-term data records of how our planet evolves. The agency freely shares this unique knowledge and works with institutions around the world.
Filling an Air Pollution Data Gap
Many cities have shortages of air quality monitors. NASA scientists have developed a tool called GEOS-CF that can help.
