Post-Landing Orthostatic Intolerance Dataset

This upload contains the full technical documentation and a free evaluation sample (32 of 10,000 virtual astronauts, same schema as the full dataset) — not the full dataset. The full 10,000-subject dataset (crew, observations at 2-second resolution, factual/counterfactual outcomes, ground-truth physiology, benchmark script) is sold separately: https://sentineldata.com.ua/dataset/post-landing-orthostatic-intolerance ($490).

Each subject is simulated with a mechanistic cardiovascular model (Ursino-Magosso variant) run from a mission-specific baseline: short-duration (5–16 days) and long-duration (129–190 days) spaceflight stints, four countermeasure arms, and continuous hemodynamic output at 1-second ...
