Humans have long dreamed of establishing a settlement on Mars. Award winning authors Kelly and Zach Weinersmith , biologist/ecologist Kelly Weinersmith and cartoonist Zach Weinersmith, in their provocative book A City On Mars, break down this dream into its various incredibly challenging parts in an effort  to answer the question: Are we really ready to head to Mars? The New York Times called the book “Forceful, engaging and funny…an essential reality check for anyone who has ever looked for home in the night sky.”
