Spaceflight Psychology and Human Flourishing: Artemis, Avocados and a New Era of Space Ethics

Summary

In this episode of PsychCrunch, Emma Barrett talks with Dr Zoe Swan Bailey about the role of psychology in spaceflight, how self-determination theory informs our understanding of human flourishing in extreme environments, and how Artemis is rethinking crew dynamics from independence to interdependence. The conversation covers the Avocados project, a voice-based tool intended to monitor astronaut health and wellbeing while preserving autonomy, rather than merely surveilling crew members. The discussion also situates these ideas within broader ethical frameworks and Earth-based applications, including healthcare and workplace settings, highlighting space as a mirror for our values on Earth.

• Artemis emphasizes crew cohesion and mutual aid over the traditional engineering focus.
• Avocados aims to empower astronauts with their own health data, not just monitor them.
• Self-determination theory and Scanlon’s what we owe to each other frame space design and ethics.
• NASA’s Human Research Roadmap signals a demand for psychology input in crewed missions.

Introduction

The podcast from PsychCrunch features Dr Zoe Swan Bailey, an aerospace neuroscientist at the Leverhulme Centre for Humanity in Space, discussing how psychology intersects with human spaceflight. The host outlines a shift in space research from purely engineering problems to questions about human flourishing in extreme environments, a theme that runs through the conversation with Zoe.

Space Psychology Foundations

Historically, psychology has supported space exploration through astronaut selection, understanding cognitive effects of microgravity, and anticipating mental health crises from space views. As space programs enter more ambitious phases, this episode argues that social sciences and humanities have a growing role in shaping the future of space exploration, particularly in ensuring that human needs, autonomy, and social connection are treated as essential infrastructure for success rather than secondary risks.

Self Determination Theory and Human Flourishing

Zoe grounds her thinking in self determination theory, which identifies three basic psychological needs autonomy, competence, and relatedness. Autonomy refers to being the author of one’s own life and protecting against coercive control. Competence involves mastery and adaptability, and relatedness denotes belonging and connection. In space, these needs are often challenged by the constraints of mission design, yet Zoe argues they must be at the center of how we conceive resilience and flourishing in space missions, not afterthoughts.

She contrasts intrinsic motivation with extrinsic rewards and emphasizes how meaningful, value-aligned work supports flourishing, not merely surviving. This framework is juxtaposed with a philosophical perspective from Scanlon, who in What We Owe to Each Other argues that morality should arise from respectful consideration of others as ends in themselves rather than mere means to an end. Applied to space, this critique suggests systems that preserve autonomy and dignity are morally superior and more likely to be mission-sustaining than those that treat astronauts as components of an engineering task.

Artemis and a Humble View of Resilience

Turning to concrete missions, the conversation compares the Artemis program with Apollo-era missions. Artemis is described as privileging social cohesion and mutual aid. The selection of crews as a family, and statements from commanders that crews return best friends, signals a shift toward interdependence. Zoe notes that a 20-minute communications delay with a Mars mission makes micromanagement untenable, pushing mission control toward supportive leadership rather than micro-level oversight. The emphasis is on a leadership style that enables crews to adapt and solve problems collectively, a move away from resilience-as-stubbornness toward resilience-as-connectedness.

Avocados: A Voice Based Monitoring Tool

Zoe introduces Avocados, a project whose name stands for Astronaut Voice Observation to capture adaptation, dysregulation and observational status. The goal is to use voice as a window into astronaut health and wellbeing, not as surveillance but as a tool for empowerment. Avocados seeks to provide astronauts with access to their own data and to help them pace energy expenditure and cognitive load in ways that align with personal baselines. The approach is deliberately distinct from typical medical surveillance and normative comparisons across populations; it centers the individual and their autonomy.

Data like jitter, shimmer and cepstral analysis are discussed to illustrate how voice features relate to autonomic nervous system activity and heart rate variability. The idea is to predict and detect subtle shifts in an astronaut's state before they become consciously perceived, thereby enabling proactive pacing rather than reactive injury. The tool is proposed for Earth-based uses as well, including chronic illness management and healthcare worker fatigue, where voice data can act as a signal to pace or take rest without requiring invasive monitoring.

Ethics, Privacy and the Human in the Loop

The discussion foregrounds a strong ethical stance on data collection. It contrasts surveillance with support, drawing on the “what we owe to each other” principle to argue that a system that erodes autonomy or privacy but only superficially sustains life is morally bankrupt. Astronauts, disabled space travelers and Earth-bound workers alike may face similar pressures to demonstrate resilience; in Zoe’s view, technology should empower, not police, and should be under the control of the person it concerns. This perspective aligns with a broader call for human-centered design in extreme environments and healthy workplace practices on Earth, including NHS workspaces and warehouse environments.

Space as a Mirror for Earth Values

Several guests emphasize the role of space exploration as a social laboratory. The Leverhulme Centre for Humanity in Space aims to integrate psychology, ethics, space science, and sustainability into space missions. The segment also mentions the NASA Human Research Roadmap as a resource that identifies crucial cognitive and psychological questions for crewed missions, inviting psychologists to contribute to addressing them. Valerie Van Mulligan and John Maltby represent scholarly voices who articulate how space research can inform the design of human-centric environments, resilience, social cohesion and meaning under stress.

Earth Applications and the Path Forward

Beyond space, the conversation highlights potential applications in terrestrial settings, including chronic illness monitoring, care settings, and high-stress occupations. The hope is that the insights generated in space can translate into improved health, wellbeing and organizational culture on Earth, underscoring the idea that space research can help solve Earth-bound problems while advancing human spaceflight.

Conclusion

The podcast closes by inviting listeners to engage with NASA’s roadmaps and to consider how psychology can contribute to the Leverhulme Centre’s mission of making humanity in space a reality that preserves dignity, autonomy and community. The overarching message is that space is a unique environment that exposes our values, and a humane approach to space will also yield healthier, more resilient humans on Earth.
