NASA Earth science studies our planet all day, every day. By tracking the movement of our natural systems – and the effect of human activity on them – we can understand the patterns, causes and results of climate change on the elemental activities that sustain us.
On Earth Day, April 22, we take time to celebrate this wondrous planet with special discussions, events (virtual) and activities. Like our satellites, however, NASA’s Earth science goes on year-round, and we continuously create videos, activities, news and more to tell the story of what’s happening on and with our planet – and all always offered free and open to the public.
For the 50th Anniversary of Earth Day in 2020, NASA created a special package of materials designed to mark Earth Day at Home. This included activities, videos, special programs and other materials in English and Spanish. You can find them all archived here.
