NASA Earth science studies our planet all day, every day. On Earth Day April 22, we take time to celebrate this wondrous planet with special discussions, events (virtual) and activities. NASA’s Earth science also goes on year-round, and we continuously create videos, activities, news and more to tell the story of what is happening on and with our planet – and all always offered free and open to the public.

NASA's Applied Sciences Program puts Earth observations to work. We're part of NASA's Earth Science Division and use unique global observations from space, air, sea and on land to help us better understand our planet’s interconnected systems.
