The recent acceleration of commercial, private and multi-national spaceflight has created an
unprecedented level of activity in low Earth orbit, concomitant with the largest-ever number …

We report a study on astronauts aimed at characterizing duration judgment before, during,
and after long-duration stays on board the International Space Station. Ten astronauts and a …

Fatigue is a significant safety concern across various domains, and accurate detection is
vital. However, the commonly employed fine-grained labels (seconds-based) frequently …

Biomarkers, ranging from molecules to behavior, can be used to identify thresholds beyond
which performance of mission tasks may be compromised and could potentially trigger the …

Introduction Clinical complications are not expected in current space missions; however, for
future long-duration missions to the Moon and Mars, a new perspective may be needed–a …

Real-time prediction of a person's trust (T), mental workload (W), and situation awareness
(SA) can improve safety and performance in operational environments. We develop …

Astronaut behavioral and mental health are key factors for space mission success. NASA's
Cognition test battery is often preceded by a brief 18-item Alertness and Mood Survey (AMS) …

David Dinges, MSc, MA, PhD, is internationally renowned for his extensive studies of the
effects of sleep loss and work hours on the neurobehavioral and physiological regulation of …

Operators' cognitive performance is often critical for success and safety in isolated, confined,
and extreme (ICE) environments such as spaceflight and wilderness medicine. Future …

A fundamental premise of this book is that medical care for spaceflight must consider the
needs of the mission as well as the needs of individual astronauts. New-to-the-world …
