Spaceflight Hypercalciuria & Kidney Stone Risk (2D)

Interactive 2D model of astronaut kidney-stone risk: microgravity bone resorption raises urinary calcium, and fluid intake, resistive exercise and potassium-citrate countermeasures set the calcium-oxalate supersaturation ratio that drives crystal growth in the renal tubule, tracked live on a drag-scrubbable risk timeline.

Losing bone mineral in microgravity does not stay in the skeleton — it passes through the kidneys. This 2D simulator models the same real chain as its 3D sibling — unloaded-bone resorption to urinary calcium excretion to calcium-oxalate supersaturation — the physiological pathway behind astronauts' elevated kidney-stone risk on long missions. Set mission duration, daily fluid intake and resistive-exercise adherence, toggle the potassium-citrate countermeasure, and watch a thinning bone-density grid, a flowing renal-tubule schematic and a live risk timeline respond: ion flow, supersaturation ratio and a growing calcium-oxalate crystal all update from the same closed-form model NASA-funded studies use to plan hydration and countermeasure protocols for Mars-length missions. Drag along the timeline to scrub the mission clock directly to any day.
