ISS Daily Summary Report – 07/29/15

Capillary Flow Experiment-2 (CFE-2)-Vane Gap: Yui reviewed onboard training materials prior to configuring the CFE Vane Gap experiment on the Maintenance Work Area (MWA).  He configured the assembly to create appropriate conditions within the CFE chamber for fluids to fill the small perforations within the chamber. The primary objective of Vane Gap is to determine equilibrium interface configurations and critical wetting conditions for interfaces between interior corners separated by a gap. Secondary objectives are to determine critical wetting transient as well as to validate numerical predictions of the large length scale discontinuous or near discontinuous wetting phenomena.  CFE involves many studies centered on a phenomenon called wetting. Wetting describes the ability and degree that a liquid spreads across a surface. The original CFE tests were highly successful at uncovering the dynamics of wetting in microgravity. Capillary Flow Experiment -2 (CFE-2) determines the critical wetting conditions for screens and perforated plates for perfectly wetting fluids. The impact of such ‘porous substrates’ has immediate implications to the design of passive geometries to manage highly wetting fuels, cryogens, thermal fluids, and contaminated aqueous solutions for urine processing. The unique vane gap critical wetting phenomena is greatly complicated by the presence of three-dimensional (3-D) porous walls. Human Research Program (HRP) Operations:  Today’s HRP operations included the Flight Day (FD) 6 Cognition, FD7 Microbiome and FD10 Salivary Markers for Yui; Habitability Observation #6 for Kelly; and the Microbiome questionnaire for Lindgren. The Biochemical Profile experiment tests blood and urine samples obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results, which scientists can use to study the effects of spaceflight on the body. The Microbiome experiment investigates the impact of space travel on both the human immune system and an individual’s microbiome (the collection of microbes that live in and on the human body at any given time). Individualized Real-Time Neurocognitive Assessment Toolkit for Space Flight Fatigue (Cognition) is a battery of tests that measure how spaceflight-related physical changes, such as microgravity and lack of sleep, can affect cognitive performance. Salivary Markers samples will be used to measure markers of latent viral reactivation (a global indicator of immune impairment and infection risk) in conjunction with salivary antimicrobial proteins and immune cell functional assays. This research study will help identify if there are any risks of an adverse health event in crewmembers due to an impaired immune system. Habitability assesses the relationship between crew members and their environment in order to better prepare for future long-duration spaceflights to destinations, such as Near Earth Asteroids (NEA) and Mars. The ultimate goal is to understand how much habitable volume is required for vehicle internal design and layout, and if mission duration impacts the volume needed. Extravehicular Mobility Unit (EMU) 3011 Return To Service (RTS): Following yesterday’s gas trap and Water Line Vent Tube Assembly (WLVTA) Remove & Replace (R&R), today Kelly and Lindgren successfully R&Rd the Fan Pump Separator. As part of the R&R, they cleaned and inspected the Primary Life Support System (PLSS). Today’s Planned Activities All activities were completed unless otherwise noted.
