The Faces

The Face on Mars, NASA 1976

Sculpture to be Seen from Mars, Noguchi 1947

"First entitled Memorial to Man, this project suggests Noguchi's pessimistic view of man's future in the atomic age, for the huge earthwork face, whose pyramidal nose was to be one mile long, was meant to inform extraterrestrials that--before the nuclear destruction of the human race--a civilized life form had existed on the planet."
