Of course, Natalie Portner was not on Mars. But she was there with her eyes, and the visual impressions the images of probes and rovers made on her led to a complex emotional response. That Emotional Response is found in the fourteen never-before-publicly-shown images reproduced in this book. A powerful appeal for a love of the world we live in and a call to live with awareness and responsibility. The art of Natalie Portner breaks the conceptual aesthetic rules of the classical concept of art. The quality of her work is in its demand on the viewer, a challenging manifesto that makes committed art and responsible living a unity.
