The review addresses the development of a new solid-state lighting system for the International Space Station (ISS) that is intended to enhance the illumination of the working and living environment of astronauts and to improve sleep, circadian entrainment, and daytime alertness.
Spaceflight missions often expose astronauts and mission support ground crews to atypical sleep-wake cycles and work schedules. A recent, extensive study describes the sleep characteristics and use of sleep-promoting pharmaceuticals in astronauts before, during, and after spaceflight. The acceptability, feasibility, and efficacy of the new ISS solid-state lighting systems are currently being tested in ground-based, analog studies. Installation of this lighting system on the ISS is scheduled to begin later this year. In-flight testing of this lighting system is planned to take place during ISS spaceflight expeditions.
If the new ISS lighting system is capable of improving circadian entrainment and sleep during spaceflight, it should enhance astronaut health, performance, well-being, and safety. Such an advance would open the door to future lighting applications for humans living on Earth.
本综述探讨了为国际空间站（ISS）开发的新型固态照明系统，该系统旨在增强宇航员工作和生活环境的照明，并改善睡眠、昼夜节律同步以及白天的警觉性。
太空飞行任务常常使宇航员和任务支持地面人员面临非典型的睡眠-觉醒周期和工作时间表。最近一项广泛的研究描述了宇航员在太空飞行前、飞行期间和飞行后的睡眠特征以及助眠药物的使用情况。新型国际空间站固态照明系统的可接受性、可行性和有效性目前正在地面模拟研究中进行测试。该照明系统计划于今年晚些时候开始在国际空间站上安装。此照明系统的飞行测试计划在国际空间站的太空飞行任务期间进行。
如果新型国际空间站照明系统能够在太空飞行期间改善昼夜节律同步和睡眠，那么它将增强宇航员的健康、表现、幸福感和安全性。这样的进展将为地球上人类未来的照明应用打开大门。
