Skin-B Sample Collection: Flight Engineer (FE)-6 Gerst conducted his second Skin-B data collection using the Tewameter probe to measure the skin barrier function; the Visioscan Camera to measure skin surface topography; and the Corneometer probe to measure skin hydration. The Skin-B experiment will improve understanding of skin aging, which is slow on Earth but very …
Advanced Colloids Experiment (ACE)-M-2 Operations: Flight Engineer (FE)-5 Wiseman installed another ACE-M-2 sample into the Fluids Integrated Rack (FIR) for processing. In the ACE-M-2 investigation, a model colloidal system is used to observe the microscopic behavior of liquids and gases separating from each other, near the critical point, via a process called spinodal decomposition. Burning …
Biological Rhythms: Flight Engineer (FE)-6 Gerst removed a digital walk holter and actiwatch to end a data take for Biological Rhythms and saved the data to a medical laptop. Biological Rhythms 48 hours studies the effects of long-term microgravity exposure on heart function by analyzing an astronaut’s electrocardiogram for 48 hours. Capillary Flow Experiment (CFE) …
Russian Extravehicular Activity (EVA) #38: EV1 Skvortsov and EV2 Artemiev successfully performed a 7 hour 23 minute EVA today. All of the planned tasks were completed: Installed [АФАР] antenna of [EKTC] (comm system) on SM conical section Relocated “Obstanovka” [ПВК-2] unit along SM handrails Verified operating condition of SM plane IV [УРM-Д] fasteners Performed experiment …
Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) Slosh: (Commander (CDR) Swanson and Flight Engineer (FE)-5 Wiseman reviewed the Slosh procedures prior to Wiseman executing a Slosh test run. Later in the day, both Swanson and Wiseman conducted a SPHERES-Slosh run. This investigation uses small robotic satellites to examine how liquids move around inside containers …
Body Measures: Commander (CDR) Swanson, with the help of Flight Engineer (FE)-5 Wiseman, conducted his Flight Day (FD) 80 session of Body Measures. He set up body marker instrumentation and took calibration and body pose pictures along with circumference measurements. Swanson then recorded a neutral body posture video. Swanson and FE-6 Gerst also collected Body …
Biological Rhythms: Over the weekend, FE-5 Wiseman donned an Actiwatch to start measurements for the Biological Rhythms investigation. Today, Wiseman attached a digital walk holter and electrodes to start taking data for his first measurement of Biological Rhythms. Wiseman will collect data for 48 hours. Biological Rhythms studies the effects of long-term microgravity exposure on …
Sprint Operations: Commander (CDR) Swanson conducted his Flight Day (FD) 75 Sprint Volume of Oxygen Utilized (VO2) protocol using the Blood Pressure (BP)/Electrocardiogram (ECG) hardware. Sprint evaluates the use of high intensity, low volume exercise training to minimize loss of muscle, bone, and cardiovascular function in International Space Station (ISS) crewmembers during long-duration missions. Burning …
Resist Tubule: Commander (CDR) Swanson retrieved the Resist Tubule Measurement Experiment Unit B from inside the Cell Biology Experiment Facility (CBEF) micro-gravity Incubator Unit (IU) and inserted the samples into the Clean Bench (CB) microscope for observation. Resist Tubule clarifies the mechanisms of gravity resistance. Gravity resistance is a principal gravity response in plants, and …
Smoke in Service Module (SM) Update: Yesterday the Russian crew reported smoke and a burning smell coming from the Water Dispensing and Heating Unit (БРП-М). The unit was subsequently dismantled, bagged, and stowed in the Progress. There was a spare unit onboard so earlier today, Flight Engineer (FE)-4 Artemyev performed a leak check and installed …
