Blood Pressure Regulation (BP Reg) Experiment: Virts set up a video camera and configured hardware in preparation for leg cuff and re-breathing protocol tomorrow. This Canadian Space Agency (CSA) investigation tests the effectiveness of in-flight manipulation of arterial blood pressure (BP) as an indicator of post-flight response to a brief stand test, since space flight negatively impacts the regulation of BP on return to upright posture on Earth. In this experiment a Leg Cuff test induces a brief drop in BP following the release of a short obstruction of blood flow to the legs. The change in BP from pre-flight to in-flight will be used to predict those astronauts who may be susceptible to experiencing the greatest drops in BP in the post-flight stand test. A second objective is to determine whether cardiac output calculated from the analysis of the finger BP waveform provides an accurate estimate both pre-flight and in-flight by comparison with a re-breathing method.
Fine Motor Skills: Kelly performed his Flight Day (FD) 10 session of Fine Motor Skills. The investigation is the first fine motor skills study to measure long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth’s gravity. The goal is to assess how fine motor performance in microgravity trends/varies over the duration of a 6-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.
Aniso Tubule: Cristoforetti removed Aniso samples from the Aquatic Habitat (AQH) microscope following 2 days of observations by ground experts. The experiment examines growth modifications of Arabidopsis hypocotyls in space. Scientists aim to analyze the changes in dynamics of cortical microtubules and microtubule-associated proteins by observing Arabidopsis hypocotyls and microtubule-associated proteins with a fluorescence microscope.
Solution Crystallization Observation Facility (SCOF) Launch Lock Fix: Cristoforetti fastened the launch lock on the SCOF in the Ryutai rack as part of planned maintenance of the Japanese Experiment Module (JEM). The SCOF is used to investigate the morphology and growth of crystals. It is equipped with several microscopes to simultaneously measure changes in morphology and growth conditions (temperature and concentration) of crystals.
Extravehicular Mobility Unit (EMU) Maintenance: Virts and Kelly performed a partial dump and fill on EMU 3010.The crew then performed a ionic and particulate filtration (scrubbing) and biocidal maintenance (iodination) of EMUs 3010 and Airlock cooling water loops. Finally the crew performed a dryout of the EMU Fan Module and Vent Loop.
On-Board Training (OBT): Kelly and Kornienko completed ISS Crew Medical Officer (CMO) Computer Based Training (CBT). Following the training they completed self-assessment questions.
