ISS Operations Update – December 8, 2015
Experiments:
Microbiome [The study will investigate the impact of long duration space flight on both, the human immune system and an individual’s microbiome. The microbiome is the totality of microbes that live in and on the human body at any given time and influence human physiology. Some consider the microbiome to be a “newly discovered organ” due to its importance for human physiology. In fact, there are about 10 times more microbial cells than human cells in and on the human body, but the microbiome only accounts for about 200 grams.]
Observation and Analysis of Smectic Islands in Space – Sample Exchange [“Observation and Analysis of Smectic Islands in Space” will study the unique behavior of liquid crystals in microgravity with special focus on their overall motion and merging of crystal layers which is known as the formation of smectic islands. Liquid crystals are widely used in technology, being employed in LCD TV screens, laptop screens, watches and other electronics with flat panel displays. The also find use in soaps and membranes. Studying liquid crystals in microgravity will provide new insights into two dimensional system physics of complex fluids. Findings may lead to understanding of well aligned, very high speed electro-optic devices that could find use in embedded ferroelectric liquid crystal micro-displays.]
Saliva Sample Collection for Kelly Twins Study
Habitability [Assessment of International Space Station Vehicle Habitability will see teams on the ground study video of the behavior of crew members within the habitable environment of ISS while the crew fills out questionnaires and collects video of areas of interest in order to provide an assessment of the habitability of ISS in its current state for a one-year mission. Results will be used to develop spacecraft with improved habitability properties to allow crew members to optimally utilize the onboard space.]
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.]
Journals [Electronic journals are kept by the crew members to allow psychologists to study behavioral issues that are associated with the isolation and confinement over long-duration space missions. Journals from 6-month ISS mission have amounted to a total of 1,100 written pages, but no data beyond those six months is available making this an interesting opportunity to study the impact of isolation in the confinements of ISS over a longer period.]
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.]
