"Stasis Sounds for Long-Distance Space Travel"
The Role of Music in Space Travel and Torpor Stasis: A Neuroscientific PerspectiveBy , Lead Scientist, CoHA Space Neuroscience DivisionAs humanity prepares for long-duration space missions, such as voyages to Mars, the challenge of maintaining astronaut health in confined, isolated environments becomes paramount.
Torpor space stasis—a hibernation-like state to reduce metabolic demands—offers a solution to logistical and physiological constraints but introduces unique psychological and neurological challenges. As the lead scientist at CoHA Space Neuroscience Division, I propose that music, particularly ambient and drone-based "stasis sounds," is a critical tool for managing the effects of prolonged stasis. Drawing on computational neuroscience and our understanding of neural dynamics, I outline how music can regulate mood, mitigate sensory deprivation, and modulate physiological states, enhancing astronaut well-being.Psychological Benefits of Music in StasisIn the austere environment of a torpor pod, where sensory inputs are minimal, psychological stressors like anxiety, loneliness, and boredom threaten mental health.
Music serves as a powerful countermeasure. By inducing specific emotional states, it can uplift mood and foster resilience. For instance, ambient music’s slow, immersive soundscapes evoke calm and contemplation, countering the isolation of deep space.
These soundscapes also combat sensory deprivation by providing rich auditory stimuli, preventing cognitive decline associated with prolonged sensory isolation.Moreover, music facilitates stress reduction by lowering cortisol levels, a critical factor in confined environments. In our neural model, where an astronaut’s brain activity is represented as, music acts as an external input () that modulates neural firing rates. Specifically, calming music reduces the amplitude of stress-related neural signals, stabilizing and promoting relaxation. For sleep regulation, music establishes a pre-torpor routine, enhancing sleep onset and quality, which is often disrupted in microgravity.Physiological Modulation via MusicMusic’s impact extends to physiological processes critical for torpor. By influencing autonomic functions, certain compositions can lower heart rate and blood pressure, supporting cardiovascular stability during reduced metabolic states. In torpor, where neural activity () is suppressed via a scaling factor , music can fine-tune this suppression to maintain a healthy baseline: Here, represents music’s auditory input, which can promote alpha and theta brainwave patterns associated with relaxation and meditation. These patterns align with the low-energy states required for torpor, facilitating entry and maintenance of stasis.Tailored Musical InterventionsOur research highlights specific musical styles optimized for stasis+), ensuring smooth transitions between conscious and unconscious states.As we refine torpor technologies, CoHA is collaborating with neuroscientists and artists to develop “stasis sounds” optimized for space travel. By leveraging music’s profound effects on neural dynamics, we can enhance astronaut resilience, paving the way for successful interplanetary missions.

Their subtle tonal shifts sustain attention () without overstimulating, ideal for unconscious processing in torpor.
\mathbf{a}_h - Classical Music- Carefully selected pieces, such as Debussy’s Clair de Lune, provide emotional resonance and familiarity, supporting psychological grounding.
- Nature Sounds- Recordings of ocean waves or forests evoke Earth’s tranquility, enhancing a sense of connection during long missions.
