ISS Operations Update – February 25, 2016


Airway Monitoring [This study looks at the occurrence and indicators of airway inflammation in ISS crew members as the result of dust particles present aboard the Space Station. The experiment uses ultra-sensitive gas analyzers to study exhaled air to assess the health impacts related to dust, especially for longer duration missions for which crew members have to be self-sufficient in atmospheric maintenance and the treatment of potential health conditions. Airway inflammation will be assessed by measuring exhaled nitric oxide. This type of diagnostic may also find application on Earth for the monitoring of asthma or other inflammatory airway diseases.]

Cognition [Cognition, also known as Individualized Real-Time Neurocognitive Assessment Toolkit for Space Flight Fatigue uses a battery of tests to measure how spaceflight-related physical changes (microgravity, lack of sleep quality, diet) can affect the cognitive performance of humans during long-duration space flights. The experiment consists of ten brief computer-based tests that cover a range of cognitive functions and deliver immediate feedback on current and past results. A good neurocognitive function for effective performance during space missions makes an investigation of sleep and fatigue in space an absolute necessity. The testing operation consists of a sleep questionnaire and subjective evaluations at the beginning followed by the ten tests that focus on: sensor-motor ability, visual object learning and memory, attention and working memory, abstraction, spatial orientation, emotion recognition, abstract reasoning, complex scanning & visual tracking, risk decision making, and vigilant attention and psychomotor speed.]

Sleep ISS-12 [The ISS-12 experiment monitors the ambient light exposure and crew member activity and collects data on the subjective evaluation of sleep and alertness. Ambient light and activity are monitored via a wrist-worn actiwatch that delivers actiwatch spectrums that are put through bio-mathematical models of sleep and light to predict circadian phase. Sleep logs will be kept by crew members as a subjective assessment of sleep quality and duration. It is hoped that this investigation can deliver requirements for lighting, sleep-shifting protocols and workloads for future space exploration missions.]


Interactions Experiment [‘Vzaimodeistviye’ (Interactions) looks at psychological aspects of long duration space flight during which different cultures come together aboard a Spacecraft such as ISS and seeks to improve crew interactions aboard ISS and with teams on the ground.]
