In 1966, Brand campaigned to have NASA release the then-rumored satellite image of the entire Earth as seen from space. He distributed buttons for 25 cents each asking, “Why haven’t we seen a photograph of the whole Earth yet?” He thought the image of our planet might be a powerful symbol. In 1968, a NASA astronaut took the photo and in 1970 Earth Day began to be celebrated. During a 2003 interview, Brand explained that the image “gave the sense that Earth’s an island, surrounded by a lot of inhospitable space. And it’s so graphic, this little blue, white, green and brown jewel-like icon amongst a quite featureless black vacuum.” During this campaign Brand met Richard Buckminster Fuller, who offered to help him in his projects.
