Today, Elon Musk's SpaceX is building one human-rated reusable spacecraft every week designed to send 100 colonists to Mars on each voyage. With this brilliant plan, SpaceX aims to colonize the Red Planet. This is not science fiction. These ships are in construction every day at a startling pace in order to make humanity a multiplanetary species, beginning this decade. Departing Earth Forever is the first manual written to and for Martian colonists—and for humankind back on the home planet witnessing this single most historic and momentous event in human history.

We live in the age of the algorithm. Increasingly, the decisions that affect our lives—where we go to school, whether we can get a job or a loan, how much we pay for health insurance—are being made not by humans, but by machines. In theory, this should lead to greater fairness: Everyone is judged according to the same rules.
