Trailing Thermal Control Radiator (TTCR) Extravehicular Activity (EVA) Post-EVA Activities: Today, the USOS crew had a half-duty day. They completed their post-EVA medical checkups, and performed an Extravehicular Mobility Unit (EMU) Water Recharge procedure on EMUs 3003 and 3008. The EMUs and associated equipment were then be prepared for storage. They then participated in an EVA debrief to discuss any comments regarding preparation and execution of the EVA.
Skin-B Operations: The Skin-B investigation was conducted as FE-6 performed Corneometer, Tewameter and Visioscan measurements on his forearm. The Corneometer measures the hydration level of the stratus coreum (outer layer of the skin), the Tewameter measures the skin barrier function, and the Visioscan measures the skin surface topography. Skin B is a European Space Agency (ESA) investigation that aims to improve the understanding of skin aging, which is greatly accelerated in space. The data will also be used to verify the results from previous testing for the SkinCare investigation on the ISS.
Space Headaches: The crew completed the ESA Space Headaches questionnaire which provides information that may help in the development of methods to alleviate associated symptoms and improvement in the well-being and performance of crew members in space. Headaches during space flight can negatively affect mental and physical capacities of crew members which can influence performance during a space mission.
Habitability Walk-through: The crew recorded a walk-through video documenting observations of life onboard ISS, providing insight related to human factors and habitability. The Habitability investigation collects observations about the relationship between crew members and their environment on the ISS. Observations can help spacecraft designers understand how much habitable volume is required, and whether a mission’s duration impacts how much space crew members need.
