Human Research Program (HRP) Operations: Yui and Lindgren performed their Flight Day 7 (FD7) saliva collection, both in support of Microbiome, and Yui collected for Salivary Markers. Throughout the day Kelly collected urine samples for Biochemical Profile and Twins Study. He also completed his FD120 Cognition session and along with Kornienko, performed the final Reaction Self-Test for the 43 Soyuz sleep shift. The Biochemical Profile experiment tests blood and urine samples obtained from astronauts before, during, and after spaceflight. Twins Study is an integrated compilation of ten different studies led by multiple PI’s at multiple centers. The studies take advantage of a very unique opportunity to look at the effects of space travel on identical twins, one of whom experiences space travel for one year; the other mains earth-bound for that same year. 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. Reaction Self Test aids crewmembers to objectively identify when their performance capability is degraded by various fatigue-related conditions that can occur as a result of ISS operations and time in space (e.g., acute and chronic sleep restriction, slam shifts, extravehicular activity (EVA), and residual sedation from sleep medications). Plant Circumnutation and Its dependence on the Gravity Response (Plant Rotation) Run 3: Yui retrieved rice plants from the Freezer-Refrigerator Of STirling cycle (FROST) and prepared Plant Rotation Chamber B of the Cell Biology Experiment Facility (CBEF). He then installed Plant Experiment Unit into the 1G rotor and Measurement Experiment Unit into the microG rotor. For Run 3, the plants will undergo microgravity rotation first followed by 1G rotation. Many species of climbing plants grow upward in a spiraling shape, a process known as circumnutation. Plant organs, such as stems, leaves, and roots also grow in a spiraling, helical shape. This spiraling process can take many forms, including very tight loops and broad curves. The Plant Rotation experiment verifies the hypothesis that this type of plant growth requires gravity. Extravehicular Mobility Unit (EMU) 3011 Return To Service (RTS) Activities: Today Lindgren and Kelly continued tasks to return EMU 3011 back to service. Lindgren finished gathering tools and hardware in preparation for tomorrow’s Fan Pump Separator (FPS) Remove & Replace (R&R). Kelly and Lindgren R&Rd the gas trap and Kelly R&Rd the Water Line Vent Tube Assembly (WLVTA). On-board Training (OBT) ISS Emergency Hardware Familiarization: Padalka and the 43S crew reviewed where emergency hardware is located on the ISS. Items covered include US Portable Breathing Apparatus (PBAs), US and Russian fire extinguishers, emergency masks, fire/ammonia cartridges and ammonia measurement kits. The crew then practiced emergency mask don/purge technique as well as demonstrated their ability to communicate with ground teams from the Soyuz while wearing emergency masks.
