Synopsis

Is there life on Mars? Dr. Sagan takes viewers on a tour of the red planet first through the eyes of science fiction authors, and then through the unblinking eyes of two Viking spacecrafts that have sent thousands of pictures of the stunning Martian landscape back to Earth since 1976. Though based on older Mars missions, Sagan's analysis still holds true.
