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.]

Ocular Health – Vision Tests, Tonometry Measurements, Blood Pressure Measurements [OH is a human physiology study. Its full name is Prospective Observational Study of Ocular Health in ISS Crews. “The Prospective Observational Study of Ocular Health in ISS Crews (Ocular Health) protocol aims to systematically gather physiological data to characterize the Risk of Microgravity-Induced Visual Impairment/Intracranial Pressure on crewmembers assigned to a 6 month ISS increment,” the NASA experiment overview said. It is known that some (not all) astronauts in orbit experience changes in visual acuity (visual clarity) and intraocular pressure as a result of fluid shifts within the body as it is subjected to microgravity. About 20% is astronauts flying to ISS have reported these kinds of changes. Test subjects will undergo pre-flight, flight and post-flight testing of their eyes using a variety of techniques.]

Calf Volume Measurements – PZEh-MO-7 (Russian Crew) [These measurements are done with the IZOG device which is a custom-sewn fabric cuff that fits over the calf. The knee and lower foot of the left leg are used as reference points. The measurements provide a rough index of deconditioning in Zero-G and can be used to assess countermeasures.]

Seismoprognoz Data Download [Seismoprognoz will measure the temporal and spatial scales of ionospheric disturbances caused by seismic phenomena in order to develop algorithms to detect plasma features of earthquakes and anthropogenic impacts from space-based instruments. The payload consists of an external monoblock, a Data Control and Acquisition Module, an attachment kit, flash memory and associated cables and connectors.]

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.]

Identification – Micro-Accelerometer Data Download [The Identification Payload records structural dynamics data inside the individual modules of the Russian Segment to provide structural data to improve spacecraft design.]

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.]
