P17 · Simulation & Synthetic Mission Dataset

Repeat the mission. Know the expected story.

Deterministic synthetic scenarios exercise sensor streams, environmental context, artifacts, missing data, connectivity loss and recovery without using real medical records.

Live dashboard
Synthetic-only safety boundary
Scenario values exist to test software behavior. They are not clinical ranges, not astronaut data and not evidence that a simulated relationship is causal.

Regenerating the same scenario and seed must preserve the same fingerprint and event sequence.

Scenario coverage
progressive fatigue/recovery pattern
CO2 context without causal claim
radiation context event
wearable artifact window
SpO2 missing-data window
offline then reconnect sequence
periodic lab context
Synthetic demonstration data are not physiological truth and are not clinical reference ranges. Values are designed to exercise software behavior, not to diagnose or predict astronaut health. CO2 and cognition are represented only as shared context; no causal inference is encoded.
Data quality
Artifact and dropout scenarios make poor, degraded and missing data visible instead of silently filling values.
Connectivity
Mission Day 127 includes a deterministic offline/reconnect sequence for P14/P15 store-and-forward demonstration.
Shared timeline
Physiological, cognitive, laboratory, habitat and radiation observations share canonical timestamps and provenance.

Simulation-only event ordering; this view does not sync, ingest, or expose authenticated mission data.

The simulator is a reproducibility and demonstration instrument. Production sensor adapters remain separate, and synthetic records are always classified and tagged as synthetic so they cannot be mistaken for real crew medical data.
