The cognitive performance of the crew has a major impact on mission safety and success in space flight. Monitoring during long-duration flight therefore is paramount importance can be performed using compact state-of-the-art mobile EEG. However, signal quality EEG may compromised due to vicinity various electronic devices constant movements. We compare noise characteristics between in-flight extraterrestrial microgravity ground-level terrestrial electroencephalography (EEG) recordings. data recordings from either aboard International Space Station (ISS) or earth’s surface, utilizing three amplifiers two electrode types, were compared. In-flight showed level an order magnitude lower when compared pre- post-flight with same system. Noise levels actively shielded cables, without similar. Furthermore, recordings, wet dry electrodes, Actively systems will support neuroscientific research neurocognitive monitoring spaceflight, especially missions.
