AquaShield: public engineering baseline
Owner: Mya P. Brown / Civic Continuum
Status: concept and calculation package; not flight-qualified hardware
Public version: 0.1 (2026-09-21)
AquaShield is a proposed closed-water, dual-use spacecraft subsystem. It
combines distributed water-wall cells with a sealed, drainable crew chamber for
resistance exercise, recovery, and short-duration refuge. The public design does
not propose an open pool in microgravity.
What the system is intended to do
- Store water in modular cells around occupied volume.
- Use that water mass as one element of a radiation-shielding strategy.
- Transfer an operationally permitted fraction into a sealed exercise chamber.
- Generate measurable hydrodynamic resistance with a controlled current and
load-bearing restraints.
- Return the water to balanced storage while filtering gas, particles, and
biological contamination.
- Isolate any leak without losing the complete water inventory.
Reality boundary
- Water can contribute useful shielding, but dose reduction depends on particle
spectrum, geometry, thickness, secondary particles, and mission profile.
- Water resistance can load muscles, but it does not recreate gravity or, by
itself, guarantee prevention of bone loss.
- A crewed flight unit cannot be claimed from calculations alone. It requires
radiation-transport analysis, human-factors review, terrestrial testing,
reduced-gravity testing, and independent safety review.
- The present contribution is an integrated architecture and falsifiable test
program. Priority, novelty, patentability, and market freedom have not been
established.

Next decision gate
The first build is an uncrewed terrestrial coupon-and-loop demonstrator, not a
spacecraft room. It must demonstrate controlled flow, gas separation, leak
isolation, emergency drain, sanitation, force measurement, and mass-balance
closure before any crew test is considered.
