The first broad stage of Mars settlement, characterized by establishing people, infrastructure, transport and the systems needed to stay.
Horizon Two
The later phase extending the story beyond the first settlement century toward mature planetary and interplanetary networks.
The Red Dawn
Era 0 (2040–2044): the first human arrival and the frail beginnings of a permanent presence.
The Autarky Years
Era 2 (2051–2060): a period when survival increasingly depended on local production, repair and reduced reliance on Earth.
