Space-bound wearable to monitor astronaut health during sleep
Astronauts on the upcoming Axiom Mission 4 to the International Space Station will test a wearable device that collects biometric data such as heart rate variability during sleep.

Sponsored by the ISS National Laboratory, the project is a collaboration between Booz Allen, Axiom Space, and Oura, who will supply their Oura Ring, which collects data on health metrics.
The demonstration will use edge computing to process and analyse biometric data in near real time, which will enable crew members to make informed decisions about whether they are prepared for critical tasks.
“This technology will provide crew members with detailed insights into their sleep quality and biometrics, which will help them to understand how this directly impacts their fitness and ability to best execute their duties the next day,” Josh Arceneaux, director of human space flight at Booz Allen, said in a statement.
According to ISS National Laboratory, the demonstration has the potential to eliminate the need for ground communication for certain activities, allowing crew members to operate more autonomously. Such capability will be vital for future long-duration missions, including those to Mars where communication delays and other challenges will become more prevalent.
