    Crew Half Duty Day: Today was a half duty day for the crew. Following Cygnus berth tomorrow, they will work Saturday to transfer cargo from Cygnus to the ISS.  Fluids Integrated Rack (FIR)/Light Microscopy Module (LMM)/Biophysics-6 experiment start:  As a followup to the discovery of the plate with damaged sample capillary(s) on Monday, today the crew removed another LMM/Biophysics-6 (Bio-6) plate from MELFI and allowed it to thaw. Following a good inspection, it was inserted in the LMM to begin the experiment. LMM/Bio-6, more formally known as Growth Rate Dispersion as a Predictive Indicator for Biological Crystal Samples Where Quality Can Be Improved with Microgravity Growth, studies ground-based predictions of which crystals benefit from crystallization in microgravity, where Earth’s gravity does not interfere with their formation. The plate installed contains samples of Geranylgeranyl pyrophosphate synthase (GGPPS) which is a protein produced in osteoporosis, multiple myeloma, and Paget’s disease. Observing crystallized proteins via X-ray crystallography on the ground allows scientists to determine how they are built, which can explain how they work or how other molecules, such as drugs, might interact with them.  Mass Measurement Device (MMD) Setup:  The crew gathered the hardware and set up the MMD in the designated module and seat track mounting location. Poweron, thermal stabilization and hardware calibration will be performed to prepare MMD for Rodent Research-12 support.

    Airway Monitoring: The crew performed the Airway Monitoring US Airlock Session consisting of two different protocols, which are performed at both ambient, and reduced pressure (10.2 psi or 700 mbar) in the US airlock. These protocols are the low Nitric Oxide (NO) protocol which determines how much NO is exhaled with the respiration, and the high NO protocol which determines how much NO is diffused into the blood. Although some issues may have been experienced with the low NO measurement system, useful science objectives were still able to be obtained. The Airway Monitoring investigation aims to determine in detail the pulmonary nitric oxide turnover in weightlessness and in combined weightless, hypobaric and hypoxic environments.  It also determines the lung diffusion capacity for nitric oxide with dust particles present in the ISS atmosphere, and studies the occurrence and indicators of airway inflammation in crewmembers. This will help to identify health impacts and support maintenance of crewmember well-being on future human spaceflight missions, such as to the Moon and Mars, where crewmembers will have to be more self-sufficient in identifying and avoiding such conditions. Cerebral Autoregulation: Using the Cardiolab Portable Doppler and European Physiology Module Facility Continuous Blood Pressure Device, the crew performed the data measurements for the JAXA Cerebral Autoregulation experiment.  As the body’s most important organ, the brain needs a strong and reliable blood supply, so the brain is capable of self-regulating blood flow even when the heart and blood vessels cannot maintain an ideal blood pressure.

    Marrow: Today the crew collected breath, ambient air, and blood samples in support of the Marrow investigation.  Marrow looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow. One of the impacts seen on the ground is fat cells growing at the expense of blood-producing cells during prolonged stays in bed.  Blood-producing cells share the same confined space with fat cells within the bone marrow. Fluid Shifts: The crew performed a repeat of the Fluid Shifts Chibis imaging session originally performed on 21-January-2019. The 21-January session experienced firewall-related video issues on the ground which resulted in a loss of ~33% of the science.  Fluid Shifts is a NASA investigation, divided into Dilution Measurements, Baseline Imaging, and Baseline Imaging with Chibis (Lower Body Negative Pressure). The Fluid Shifts experiment investigates the causes for severe and lasting physical changes to astronaut’s eyes.  Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a lower body negative pressure device is being evaluated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and prevention of eye damage. Treadmill 2 (T2) Six-Month Maintenance: The crew completed the 6-month T2 inspection. During this task, the crew inspects the treadbelt slats and screws, cleans the treadmill drive shaft, and vacuums inside ... read more

    Combustion Integration Rack (CIR) Manifold Bottle Replacement: In support of part 2 of the CIR / Advanced Combustion via Microgravity Experiments (ACME) / Electric-Field Effects on Laminar Diffusion (E-FIELD) Flames operations, the crew removed the 30% ethylene, 70% nitrogen fuel bottle and replaced it with a 100% methane fuel bottle today.  For E-Field Flames, an electric field with voltages as high as 10,000 volts is established between the burner and a mesh electrode. The motion of the charged ions, naturally produced within the flame, are strongly affected by a high-voltage electric field. The resulting ion-driven wind can dramatically influence the stability and sooting behavior of the flame. Conducting the tests in microgravity allows for simplifications in the analysis, enabling new understanding and the development of less pollution and more efficient combustion technology for use on Earth.  Electro-static Levitation Furnace (ELF) Sample Holder Insertion: The crew performed an ELF sample holder insertion. ELF is an experimental facility designed to levitate, melt and solidify materials by containerless processing techniques using the electrostatic levitation method.  With this facility, thermophysical properties of high temperature melts are measurable and solidification from deeply undercooled melts can be achieved.  ELF typically processes oxide samples, but is also capable of processing semiconductors, alloys, and metals. Grip Supine Science Session: The crew was scheduled to perform the third part of Grip science tasks (third out of three this week) in the supine position. However, the session was only partially completed. Data is being downlinked and the ground team is ... read more

    Binary Colloidal Alloy Test – Cohesive Sediment (BCAT-CS):  Today, the crew transferred images to the Station Support Computer (SSC), replaced the SB-800 Flash batteries, verified the camera alignment and focus are still intact, and re-set the intervalometer.  BCAT-CS continues to produce interesting data resulting in an extension past the original 2-4 week run duration.  BCAT-CS focuses on the study of forces between particles that cluster together by using sediments of quartz and clay particles. Conducting the research in the microgravity environment of the ISS makes it possible to separate the forces acting on the particles over a short range (adhesive forces) versus those acting over a long range (cohesive forces). The quartz/clay system is commonly found in a wide variety of environmental settings (such as rivers, lakes, and oceans) and plays an important role in technological efforts related to deep-sea hydrocarbon drilling and carbon dioxide sequestration. Echo Setup and Stow:  The crew retrieved the Echo hardware and deployed it in the Columbus module so the ground could perform maintenance activities. The purpose of the Echo investigation is to evaluate a tele-operated ultrasound system, equipped with motorized probes controlled by flight controllers on the ground. Additionally, this investigation serves to perform the commissioning of the Echo instrument, which is planned to be used for the Canadian Space Agency (CSA) Vascular Echo experiment in the future.

    Actiwatch Spectrum:  Following the discovery of some bad data from a previous Actiwatch spectrum data collection, this activity set up the nine remaining Actiwatch spectrum units to verify they are producing good data. The Actiwatch Spectrum is a waterproof, nonintrusive, sleep-wake monitor worn on a crewmember’s wrist. The device contains an accelerometer for measuring motion and color sensitive photodiodes (a photodetector capable of converting light into voltage) for monitoring ambient lighting. Together, these capabilities enable the Actiwatch Spectrum to analyze circadian rhythms, sleep-wake patterns, and activity. Grip Seated Science Session:  The crew completed the Grip seated session which is the first of three Grip activities for the week.  Pending verification of the downlinked data, the ground reported the session went well.  ESA’s Grip investigation tests how the nervous system takes into account the forces due to gravity and inertia when manipulating objects.  Results from this investigation may provide insight into potential hazards for astronauts as they manipulate objects in different gravitational environments, support design and control of haptic interfaces to be used in challenging environments such as space, and provide information about motor control that will be useful for the evaluation and rehabilitation of impaired upper limb control in patients with neurological diseases. Spaceflight Effects on Neurocognitive Performance: Extent, Longevity, and Neural Bases (Neuromapping):  The crew performed a NeuroMapping Experiment Neurocognitive Test which includes testing in both “strapped in” and “free floating” body configurations. The investigation studies whether long-duration spaceflight causes changes to brain structure and function, motor control, and ... read more
