Your home. Our Mission.
And the one planet that NASA studies more than any other.

Earth Action

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.

PACE will help us better understand our ocean and atmosphere by measuring key variables associated with cloud formation, particles and pollutants in the air, and microscopic, floating marine life (phytoplankton).…

Greenhouse Gases

NASA has several instruments and tools for measuring and modeling greenhouse gases – where they come from, where they go, and how they are driving climate change. The agency works with federal, state, and international partners to make this information freely available.

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.
