Documentation-first architecture repo for astronaut radiation protection, centered on hydrogen-rich shielding, chambered wall and storm-shelter concepts, dosimetry-aware operations, and disciplined modeling for GCR and SPE/SEP risk reduction.

PressureX is an engineering evaluation package for a passive layered structural mitigation concept using shear-thickening fluid behavior to broaden impulsive loads and reduce peak transmitted response in high-vibration aerospace structures. Targets are design-intent until validated.
