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.

Air Quality
Air pollution is a significant threat to human health and our environment. Instruments on NASA satellites, along with airborne and ground-based sensors, are constantly collecting data on major pollutants in our atmosphere.

SWOT: The First Year
Launched in December 2022, the Surface Water and Ocean Topography (SWOT) satellite – led by NASA and France's Centre National d’Études Spatiales (CNES) – is giving scientists unprecedented detail about the water on Earth’s surface. Here are a few stories from its first year.
NASA has a unique vantage point for observing the beauty and wonder of Earth and for making sense of it. Looking back from space, astronaut Edgar Mitchell once called Earth “a sparkling blue and white jewel,” and it does dazzle the eye.
