Prior state
At the interval's start cislunar operations are routine, a small permanent human presence exists, Mars has been visited without being inhabited, and the settlement question remains genuinely open — advocated, funded in part, and unresolved by evidence.
Material change
The century resolves the question in a specific direction. Off-Earth activity becomes economically self-justifying within a narrow band: propellant and volatiles extracted from lunar ice, structures and optics fabricated in vacuum and microgravity, energy and sensing services, and processes unwelcome inside a biosphere. Human presence stabilizes in the thousands to low tens of thousands, overwhelmingly rotational rather than resident. Meanwhile the settlement thesis fails on biology rather than engineering: partial-gravity development, cumulative radiation exposure over decades, and above all mammalian gestation and childhood development off Earth prove intractable within the interval, and the attempts that are made produce results grim enough to end the political case.
Why now
Mid-century, because the resolving evidence is biological and cannot be gathered faster than the lifetimes involved. Questions about gestation, skeletal and neural development, and lifetime radiation dose require decades of cohort observation, and the cohorts do not exist until the interval's early decades. The industrial band, by contrast, is established early and simply becomes obviously profitable while the settlement case becomes obviously not.
Mechanism and resistance
Resistance comes from the settlement movement, whose commitment is ideological and does not respond to evidence, from states pursuing prestige, and from the sunk-cost logic of very large programs. The resolution is therefore not a decision but an accumulation: capital drifts toward the profitable band, insurers refuse the other, and the political constituency ages out. Physical resistance is the deeper story — radiation shielding scales with mass, artificial gravity scales with structure, and both scale badly.
Consequences
A resource-claims regime consolidates that is not territorial sovereignty but licensed, registered, time-limited extraction rights with priority rules, enforced by the launching jurisdictions because they control the only chokepoint that matters. Off-world labour becomes a regulated, highly paid occupational class with its own health law, dose limits, and pension arrangements, and its disputes over exposure standards are among the century's more consequential labour conflicts. Culturally, the shift matters: space stops being a destination and becomes infrastructure, which removes a redemptive story that several political traditions had relied upon and forces them to make their arguments about Earth.
End state
A permanent industrial periphery exists beyond Earth, economically real but small relative to the planetary economy, with no self-sustaining human community anywhere off Earth. A functioning property-and-liability regime governs extraction. The reproduction question is closed for the century rather than forever, and is regarded at the interval's end as a problem for a later era.
Observable test
sustained off-Earth industrial output entering cislunar or terrestrial markets on commercial terms, together with the absence of any off-Earth population capable of demographic self-replacement and the absence of a resident multi-generational community.
Disconfirming sign
a healthy cohort conceived, gestated, and raised off Earth reaches adulthood within the interval.
