Freesphere

Inflated free fall habitat

This Freesphere, in orbit around Hiederia, holds a number of freeform microgravity structures which serve as habitats and workshops for the low-gravity tweaks who live there

Free fall habitat often used as a recreational area in an orbital band or as habitation for the space adapted.

Freespheres are large, transparent, double-walled open bubbles, ranging from several hundred meters to several thousand kilometers across, filled with air. Appropriately modified lifeforms create a free-fall ecology and a layer of water between the inner and outer walls, combined with magnetic screening, provides an effective radiation shield. Freespheres are especially popular when placed in planetary orbit due to both the spectacular views and the sense of truly flying 'above' something rather than merely floating in space.

For freesphere diameters greater than 100km, stronger materials and additional re-enforcing structures are required. This reenforcement attenuates the views, as does the longer sight lines through the internal atmosphere, but with a hull completely made of buckycables a Freesphere can be made much larger than a rotating habitat made of the same material; as large as 5,000 km across even with full, baseline comfortable, atmospheric pressure.

Freespheres may employ complex internal environmental systems, including airwalls, fusion or conversion reactor "suns", and various feedback-based systems to promote airflow, control temperature, and manage both general humidity and larger concentrations of moisture (ranging from small "pools" to "seas" several kilometers across).
