Earthlings were fascinated by Mars long before sending rovers and landers to beam back three-dimensional color pictures of its surface. Does it have canals? Did little green men ever inhabit the planet? Will humans ever walk or live on Mars? NPR's Neal Conan and guests discuss the history and mystery of Earth's neighbor, from Galileo to War of the Worlds and beyond.
