Astronauts aboard the International Space Station (ISS) will be equipped with a wearable device that will collect biometric data such as total sleep time and heart rate variability during sleep.

The project from the ISS National Laboratory, Booz Allen, Axiom Space and Oura aims to utilise edge computing to analyse biometric data in near real time, enabling crew members to make informed decisions about whether they are prepared for critical tasks. The astronauts will be fitted with Oura rings – commercially available devices that are capable of capturing metrics such as body temperature, menstrual cycle and blood oxygen.

“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,” said Josh Arceneaux, director of human space flight at Booz Allen.

The health impact of space on astronauts can be considerable, with changes...
