Leaving Earth: Why One-Way to Mars Makes Sense

We are now at the cusp of settling other worlds. The current timeline for a Mission to Mars is still over 20 years off, but it doesn't have to be. Leaving Earth demonstrates why we should go to Mars, and why when we do going one-way - not to die, but to live - actually makes a lot of sense.
Simply put, a one-way trip maximizes the return, minimizes the cost, and is by far the most logical way to organize a mission from almost every standpoint. Leaving Earth is fast-paced and full of fascinating historical, scientific, and personal anecdotes, both serious and humorous. It is aimed at a non-technical audience, and should be accessible to anyone.
Although technology is a major focus, the mission would primarily be a human adventure. As such, the book examines the risks and human impacts in personal terms. Who would chose to give up their life on Earth to start a new one on another planet? What would that be like? What would be given up, and what would be gained? Moreover, how could such a mission be accomplished, both technically and financially?
