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.]

Microbiome Sampling & Survey [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.]

Dynamic Surf experiment hardware reconfiguration [Dynamic Surf is part of a series of experiments examining Marangoni convection that occurs in the presence of surface tension gradients produced by a temperature difference at a liquid/gas interface creating a flow of material.]

Saliva Sample Collection for Kelly Twins Study

Space Headaches Questionnaire

Radiation Area Monitors (RAM) Retrieval

Otklik Experiment Hardware Check [Otklik uses several piezoelectric sensors to track the impacts of small particles and debris on the exterior of the International Space Station to monitor the abundance of debris events and a series of other characteristics. These measurements provide valuable data for the construction of future spacecraft]
