Getting to Mars is not the hard part.

Staying there is.

Every discussion of Mars focuses on rockets, timelines, and spectacular launches. Far fewer confront the real challenges: power that never fails, systems that tolerate decay, logistics that persist without rescue, and human survival when Earth is no longer close enough to help.

The Mars Frontier explores what permanent presence beyond Earth actually requires — not through fantasy or hype, but through physics, engineering, and hard constraints. From molten-salt reactors and nuclear propulsion to autonomous construction, closed-loop life support, and off-world logistics, the book traces how stable energy reshapes everything: safety, economics, autonomy, and expansion.

This is not a story about flags and footprints.

It is about infrastructure, persistence, and designing systems that can endure when nothing is guaranteed.

Mars does not become affordable when it becomes cheap.

It becomes affordable once it becomes viable.
