Science & sources
Transparent context. Clear limitations. No hidden medical claims.
Bio-Monitor combines a smart shirt, headband and tablet to record pulse/ECG, blood pressure, breathing, skin temperature, oxygen saturation and activity on the ISS. This is an existing CSA system, not evidence that Nabd has implemented or validated those measurements.
Astroskin testing in HERA assessed signal quality, crew usability and comfort before considering future spaceflight use. An analog technology demonstration does not validate Nabd hardware, thresholds or clinical performance.
The Space Health study uses Bio-Monitor data and the Artemis AI platform to investigate cardiovascular adaptation in spaceflight. Research use of AI is not evidence that this assistant can diagnose or predict an individual health outcome.
NASA identifies sleep loss, circadian desynchronization and work overload as risks for performance decrements and adverse health outcomes. This risk framework does not validate Nabd sleep estimates, scores or individual thresholds.
NASA reviews cognitive, behavioral and psychiatric risks for in-mission health, performance and long-term outcomes. A mood score or chat response is not a psychiatric assessment. Persistent distress requires human support.
Radiation, isolation/confinement, distance from Earth, gravity fields and closed environments frame human spaceflight risks. Hazard descriptions provide context, not clinical validation of Nabd rules or the conceptual circuit.
The environmental framework behind NABD: radiation, isolation, distance, gravity, and closed habitats.
Human Research Program evidence and risks, from physiological adaptation to behavioral health.
Research investigating how the human body adapts and how countermeasures can protect crew.
Personal radiation monitoring and astronaut exposure research.
How microgravity research improves understanding of health on Earth and in space.

Limitations & ethics
No real astronaut records are used. All crew identities and readings are synthetic. Public demo data is shared and is not confidential. Camera video and local photo previews stay on the device. Simulated camera pulse is explicitly labelled; validated rPPG and medical image analysis are not enabled. Activity indices are not bone-density measurements. NASA hazard sources provide context, not validation of these illustrative thresholds. Source links have not been independently verified for availability.
