Operating Manual For Spaceship Earth is a short book by R. Buckminster Fuller, first published in 1969. The book imagines our species as a crew, united by a shared fate, on a tiny spaceship traveling through infinity. The spaceship has a finite amount of resources and cannot be resupplied. It can be read even today as the most intelligent metaphor for thinking about humankind on this planet. Fuller accepted the challenge presented by this metaphor, using his inventions and writings to contribute to the safe operations of Spaceship Earth.
