‘Gran Horizonte: Curriculum For a New City’
Alfredo Brillembourg & Hubert Klumpner

On December 7, 1972, a few hours into their mission, the crew of the Apollo 17 spacecraft turned away from their destination – the moon – and looked back to where they had come from – the Earth. They photographed what they saw, and their photograph of a fully illuminated Earth has become one of the most widely distributed images of all time. What captured the world’s imagination on that day was not an image of what lay in outer space, but a new image of our own world; a new way of perceiving what we thought we understood.
