Body Measures: Earlier this morning, the 49S subject performed the Body Measures Flight Day (FD) 135 session. With assistance from a trained operator the crew conducted a Body Measures data collection, configuring still cameras and video and collecting the Neutral Body Posture video prior to stowing the equipment. NASA is collecting in-flight anthropometric data (body measurements) to assess the impact of physical body shape and size changes on suit sizing. Still and video imagery is captured and a tape measure is used to measure segmental length, height, depth, and circumference data for all body segments (chest, waist, hip, arms, legs, etc.) from astronauts before, during and after their flight missions. Fine Motor Skills (FMS): The crew performed their FMS sessions this morning on a touchscreen tablet where the crew completes a series of interactive tasks. The investigation studies how fine motor skills are effected by long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth’s gravity. The goal of FMS is to answer how fine motor performance in microgravity trend/vary over the duration of a six-month and year-long space mission; how fine motor performance on orbit compare with that of a closely matched participant on Earth; and how performance trend/vary before and after gravitational transitions, including the periods of early flight adaptation, and very early/near immediate post-flight periods. Advanced Colloids Experiment Temperature Control -1 (ACE-T-1) Module Installation: The crew reconfigured the Fluids Integrated Rack (FIR) Light Microscopy Module (LMM) for the ACE-T-1 experiment. ACE-T-1 studies tiny suspended particles which have been designed by scientists to connect themselves in a specific way to form organized structures in water. The particles that were flown on HTV-6 are cylindrical in shape versus bullet-shaped that the previous ACE-T-1 module investigated. Materials having complex structures and unique properties potentially can be made with additional knowledge of how these particles are joined together and the conditions which control their behaviors. FIR is a complementary fluid physics research facility designed to host investigations in areas such as colloids, gels, bubbles, wetting and capillary action, and phase changes including boiling and cooling. Environmental Health System (EHS) Compound Specific Analyzer-Combustion Products (CSA-CP) Maintenance: The crew completed this regularly scheduled maintenance to replace the battery packs and zero calibrate all CSA-CPs. U.S. Extravehicular Activity (EVA) #41 Preparations: In preparation for this Thursday’s planned EVA, the crew performed the following: Configured tools required for the EVA. Inspected all safety, waist tethers and D-ring extenders for structural integrity. Installed Rechargeable EVA Battery Assembly (REBA) in EMUs 3006 and 3008. Configured Dynamic Onboard Ubiquitous Graphics (DOUG) to receive and display real-time Space Station Remote Manipulator System (SSRMS) joint angle telemetry from a Portable Computer System (PCS) laptop. Also start and configure DOUG without real-time SSRMS joint angle telemetry. Today’s Planned Activities All activities were completed unless otherwise noted.
