Armband, Night Headband Sleep Experiment, Shuttle-Mir Science Project

The night headband system was part of an experiment to monitor eye and head movements while an astronaut slept to understand better the quality of sleep in weightlessness. The headband was wired to collect data from the attached T-shaped sensors that fit on the person's upper eyelids. Data flowed to a small monitor worn in an armband. The headband kit contained all the materials necessary for the experiment, including skin temperature thermometer strips and a voice recorder for personal comments. John Glenn participated in an experiment like this on the STS-95 space shuttle mission in 1997, and crewmembers on several shuttle-Mir missions also participated in this joint Russian-American science project.NASA transferred this experiment kit to the Museum in 2012.
