Circadian Rhythms: Yesterday a crewmember instrumented themselves with Thermolab Double Sensors and mounted the Thermolab Unit to their belt, which began 36 hours of monitoring for the Circadian Rhythm investigation. Circadian Rhythms investigates the role of synchronized circadian rhythms, or the “biological clock,” and how it changes during long-duration spaceflight. Researchers hypothesize that a non-24-hour cycle of light and dark affects crew members’ circadian clocks. The investigation also addresses the effects of reduced physical activity, microgravity and an artificially controlled environment. Changes in body composition and body temperature, which also occur in microgravity, can affect crew members’ circadian rhythms as well. Understanding how these phenomena affect the biological clock will improve performance and health for future crew members. Fine Motor Skills (FMS): Today a 51S crewmember completed a Flight Day 85 FMS session which was executed on a touchscreen tablet, where the subject performs a series of interactive tasks. The investigation studies how fine motor skills are affected by long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth 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 compares with that of a closely matched participant on Earth; and how performance trends/varies before and after gravitational transitions, including the periods of early flight adaptation, and very early/near immediate post-flight periods. Space Headaches: The crew completed the weekly questionnaire for the ESA Space Headaches investigation. The Space Headaches investigation collects information that may help in the development of methods to alleviate associated symptoms and improvement in the well-being and performance of crewmembers in space. Headaches during space flight can negatively affect mental and physical capacities of crewmembers that can influence performance during a space mission. USOS Extra-Vehicular Activity (EVA) #46 Preparations: Today the crew conducted a review of EVA procedures and a conference with ground teams. They also inspected tethers, configured tools, printed cuff checklists, and prepared the equipment lock in preparation for tomorrow’s EVA. The goals of USOS EVA #46 include Removal and Replacement (R&R) of the Latching End Effector (LEE) A Camera Lens Assembly (CLA). Tablet Updates: As part of the ongoing efforts to update the operating system on the onboard tablets, the crew performed steps to update and configure those tablets. Remote Power Control Module (RPCM) P12B-B R&R: Wednesday morning, ground teams completed the robotic activities to swap RPCM P12B-B with P13A-G. On Monday night RPCM P12B-B was extracted and installed into empty truss slot P11A-D and the replacement RPCM was removed from slot P13A-G, however it could not be inserted into the P12B-B at that time. Robotics activities resumed on Tuesday afternoon and teams were able to successfully install the replacement RPCM in the P12B-B slot after 47 wiggle and push attempts. The new P12B-B RPCM powered up nominally. Ground teams then removed the failed RPCM from the P11A-D truss slot and relocated it to the P13A-B slot successfully. The power up of the P13A-G RPCM was also performed nominally. This completes the RPCM swap activities. JEM Airlock (A/L) Reconfiguration: Today, the crew removed the MBSU from the JEM A/L where it had been stowed after the I-Level maintenance was performed in early September. The Kaber plate and adapter plate were then installed on the A/L slide table in preparation for installation of the KE2M satellite on Monday. After KE2M and SIMPL, another JEM A/L-deployed satellite, are deployed next week, the MBSU will be returned to the JEM A/L for transfer and installation externally at External Stowage Platform 2 (ESP2). External Robotics Operations: Overnight, robotics ground controllers stowed the Special Purpose Dexterous Manipulator (SPDM) and configured the SSRMS to be in position for the EVA tomorrow. The SSRMS is now based on LEE B, at Mobile Base System (MBS) Power Data Grapple Fixture 4 (PDGF), Worksite 6. LEE A is ready to receive a new LEE CLA. Today’s Planned Activities All activities were completed as scheduled unless otherwise noted.
