Earth Day

Learn about Earth Day founder Gaylord Nelson (1916-2005) and how environmental disasters of his day inspired the creation of Earth Day in 1970. On December 7, 1972, Apollo 17 astronauts captured a now-iconic image of Earth, sometimes called the “blue marble.” Our National Air and Space Museum explains how it became an inspiration and symbol for continuing Earth Day celebrations
