Solar système scope. Eyes on the Earth. From the unique vantage point in space, NASA collects critical long-term observations of our changing planet. NASA applies ingenuity and expertise gained from decades of planetary and deep-space exploration to the study of our home planet. The Earth Science Division operates more than 20 satellites in orbit, sponsors hundreds of research programs and studies, and funds opportunities to put data to use for societal needs.
We develop new ways to observe the oceans, land cover, ice, atmosphere, and life, and we measure how changes in one drive changes in others over the short and long term. While listening to and collaborating with industry leaders, international partners, academic institutions, and other users of our data, we deepen knowledge of our planet, drive innovations, and deliver science to help inform decisions that benefit the nation and the world.
