Do the published space-economy totals describe the same industry?
The main series differ substantially, and the corpus is explicit that the differences are definitional rather than empirical — a disagreement about which segments count, not about what happened. None of the three series was retrievable when the canonical pack was written, so the record states the shape of the split and no figures at all. Every chapter here is built to survive that absence.
What does a launch actually cost, as opposed to what it is offered at?
Unknown outside the company that flies it. The provider is privately held, publishes no audited accounts and is its own largest customer, so the single most consequential number in the modern sector is an estimate — and the published cost-per-kilogram series say so in their own methodology. The Journey therefore treats the advertised price as a commercial offer and never as a disclosure.
Can subscription revenue fund perpetual replacement of a decaying fleet?
Genuinely unresolved. No constellation has yet funded a complete replacement cycle from operations, the largest operator discloses nothing audited, and published subscriber and revenue figures are estimates. The canonical pack deliberately quotes no satellite count and no subscriber number, and this package repeats none.
Is low Earth orbit already past a cascade threshold?
Contested. Models disagree on removal rates, on how many fragments a collision produces, and on how much active manoeuvring offsets the risk. The standard annual measurement was not retrievable when the canonical pack was written, so no population figure is quoted anywhere in this Journey, and the mechanism is presented without a number attached to its current state.
What would a multi-day national loss of the timing signal actually cost?
A modelled estimate rather than an observation — no country has experienced one. The most-cited attempt is a study prepared for the United Kingdom, whose headline figure the corpus carries only as a magnitude because the report itself was not retrieved, and estimates of this kind are highly sensitive to assumptions about how fast systems degrade. The finding worth keeping is not the figure but that nobody had priced the dependency until somebody asked.
Will any commercial microgravity platform be flying when the station comes down?
Open, and it decides whether in-space manufacturing has a venue at all after the station's planned end of operations. A deorbit vehicle has been contracted; the status of successor platforms could not be established when the canonical pack was written. This Journey names the deadline and declines to guess at the answer.
Where, exactly, is the space economy?
The decisive geography of this subject is a set of orbital altitude bands, and canonical knowledge places none of them — a shell has no coordinate, so it cannot appear as a place. Everything this Journey can put on a map is a spaceport or an institution's address, which is to say the parts of the industry that touch the ground. The absence is recorded here rather than papered over with a pin.
