All eight Solar System planets are listed separately; Mercury, Venus, Uranus, and Neptune have further destination planning in the backlog. Jupiter and Saturn provide orbital scenery and access to their documented moons. The atlas is not to scale.",

IP07 Frontier industry supports Mars and optional Ceres; IP08 Outer-world systems supports Europa, Titan, Pluto and optional Io; IP09 Interstellar science supports Cairn and Morrow. The five journey families remain First Descent, Pale Horizon, Red Frontier, Outer Worlds and Beyond Sol. Industrial bands are not rocket tiers. Core, Heartglass, titanium, advanced chemical refining and nuclear power are not first-flight requirements.",

The established engineering envelope is 512 total block levels, from Y minus 192 through 319. Core is the fictional deep-crust Heart environment, not the literal center of Earth.",

The diagram shows conceptual access, not literal geological layers. Roof openings can also connect the surface and galleries. Regolith Ceramic and Lunar Glass Filament improve habitation and instruments. The default first complete mission brings a working airlocked cabin and an Earth-carried EQ25 starter shelter, commissioned before the first committed descent. Equipment and protected return reserves come from Earth; caves are not automatically breathable.",

Managed projects, production, visitors and events operate only with eligible participants inside horizontal, vertical and dimension bounds, otherwise parking safely.

Earth uses established metals, ceramics and cultivated fibres for serviceable tools and first planetary support. Regolith Ceramic and Lunar Glass Filament improve habitat parts, compact lights and instruments. Ferric Lattice and Brine Catalyst improve field frames, repairs and selected processing or habitat functions. Processing refers to the shared TEC machine families. These are relationship examples, not crafting recipes; first-arrival equipment uses earlier sources and essential supplies never require killing rare creatures.",
