A new frontier for
autonomous health intelligence.
This proposal establishes a flight-validated, agentic neurobehavioral monitoring and resilience system for deployment in isolated, confined, and extreme environments — beginning with commercial orbital missions by Vast Space.
The system is a psychotherapy-informed, closed-loop conversational agent that integrates structured behavioral dialogue with physiological telemetry to model the coupling between emotional regulation, cognitive load, and autonomic cardiovascular stability.
Why ARPA-H.
Why now.
ARPA-H has identified agentic AI and cardiovascular health transformation as critical frontiers in autonomous care. This proposal aligns with that mandate across three dimensions:
"Structured, psychotherapy-informed conversational engagement can generate quantifiable behavioral markers that correlate with, and potentially predict, short-term deviations in cardiovascular autonomic stability during spaceflight."
Flight validation
architecture.
Initial validation during a short-duration commercial orbital mission. Crew members voluntarily engage with the BriteMind agent 6–8 minutes per day — zero operational interference. Each astronaut serves as their own baseline control across pre-flight, in-flight, and post-flight timepoints.
| Outcome | What It Measures | Priority |
|---|---|---|
| Emotional Variability → HRV Coupling | Correlation between conversational Emotional Variability Index and deviations in heart rate variability from individual baseline | Primary |
| Cognitive Drift → Sleep Efficiency | Relationship between perceived cognitive drift and sleep efficiency reduction over mission timeline | Secondary |
| Interpersonal Strain → Sympathetic Activation | Interpersonal strain markers correlated with transient sympathetic activation events | Secondary |
| Compliance & Acceptability | Overall acceptance of low-burden agentic dialogue in confined operational spaceflight conditions | Secondary |
Deterministic safety
by design.
- No medication guidance, diagnostic labeling, or medical directives
- Participation is fully voluntary — sessions skippable without consequence
- Raw narrative content is NOT transmitted — tokenized into structured feature vectors only
- Predefined escalation protocols if distress markers exceed thresholds
- No automatic ground notification without astronaut consent (except clear emergency)
- IRB review anticipated — HHS-compliant human subjects protections
- De-identified data segregated from mission performance evaluation channels
Three tangible
deliverables.
Space is the proving ground.
Earth is the mission.
If neurobehavioral conversational markers reliably correlate with autonomic instability in orbital conditions, this technology immediately extends to environments on Earth where clinicians cannot be present:
The long-term vision: an FDA-authorizable agentic system that augments cardiovascular monitoring with behavioral state detection — at scale, without clinicians.
