3DMM: The crew continued the 3DMM experiment by collecting samples from the Node 2 area. This investigation will conduct a series of over 800 swab sample collections throughout several modules of the International Space Station. Surfaces in the space station contain microbes and associated biomolecules excreted by these microorganisms. Three-dimensional Microbial Mapping of ISS Environment (3DMM) uses DNA sequencing and other analyses to construct a 3D map of bacteria and bacterial products throughout the station. The team also plans to characterize how these microbes respond at a molecular level to specific stress conditions, including altered gravity and atmospheric composition.
Antimicrobial Coatings (Boeing Environment Responding Antimicrobial Coatings or AC): The crew touched each coupon on AC placard. Boeing Environment Responding Antimicrobial Coatings tests an antimicrobial coating on several different materials that represent high-touch surfaces. Some microbes change characteristics in microgravity, which could create new risks to crew health and spacecraft systems as well as creating the possibility of contaminating other planetary bodies. The samples remain in space approximately six months then return to Earth for analysis.
Astrobee: The Astrobee systems were powered on and stowage in the area cleared away to allow the performance of free-flight maneuvers. This type of activity is commonly called “crew minimal” and the goal is for the ground to command the Astrobee units and their dock to complete the objectives for the session. Astrobee is made up of free-flying, cube-shaped robots which are designed to help scientists and engineers develop and test technologies for use in microgravity to assist astronauts with routine chores, and give ground controllers additional eyes and ears on the space station. The autonomous robots, powered by fans and vision-based navigation, perform crew monitoring, sampling, logistics management, and can accommodate up to three investigations.
GRIP: The crew set up the appropriate hardware and performed tasks associated wth a “supine science 3” session. In this test, the crew performed the same tests as seated Sci-2 (tasks related to friction, collisions, etc), but in the supine position. The GRIP experiment studies the long-duration spaceflight effects on the abilities of human subjects to regulate grip force and upper limbs trajectories when manipulating objects during different kind of movements: oscillatory movements, rapid discrete movements and tapping gestures.
JEM airlock: In preparation for the later installation of an ISS Experience camera, the crew reconfigured the hardware/adapters on the JEM airlock slide table. The International Space Station Experience (The ISS Experience) is a cinematic virtual reality (VR) series documenting life and research aboard the space station. Filmed over multiple months, the immersive VR series documents different crew activities – from science conducted aboard the station to preparation for a spacewalk. The ISS Experience uses a Z-CAM V1 Pro Cinematic Virtual Reality (VR) 360-degree camera with nine 190° fisheye lenses.
Light Ions Detector (LIDAL) for ALTEA Relocate: The crew relocated the LIDAL hardware in a different orientation to begin a 6 month radiation observation period in the different orientation. LIDAL upgrades the ability of ALTEA (Anomalous Long Term Effects in Astronauts) to make measurements that can be converted, by dedicated software in real-time, into radiation risk coefficients – effectively enabling ALTEA to become the first ever dosimetric “risk meter” aboard the International Space Station. Knowledge of the radiation environment aboard the ISS is mandatory to provide information for radiation risk assessment, and to validate models and define possible countermeasures.
Plant Water Management: The crew completed the second part of the PWM hydroponics operations, followed by the cleanup and stow. The ground team was very happy with the science obtained by the session. The hydroponics activities served to demonstrate the first stable microgravity hydroponic watering method ever using a unique, open capillary watering channel and a simulated plant (s). The PWM investigation demonstrates passive measures for controlling fluid delivery and uptake in plant growth systems. Reduced gravity creates challenges in providing adequate fluid and nutrition for plant growth. This investigation examines using other physical properties such as surface tension, wetting and system geometry to replace the role of gravity.
Solid Combustion Experiment Module (SCEM)/FLARE: The crew set the configuration of the SCEM valves to continue the setup/checkout of the SCEM/FLARE hardware. Fundamental Research on International Standard of Fire Safety in Space – Base for Safety of Future Manned Missions (FLARE), a Japan Aerospace Exploration Agency (JAXA) investigation, explores the flammability of materials in microgravity. Various solid fuels are burned under different conditions and observed inside a flow tunnel. Microgravity significantly affects combustion phenomena and results are expected to contribute to the improvement of fire safety in space
SUBSA-CETSOL Sample Exchange: The crew performed the steps necessary to remove the processed science ampoule and install a new one. Effect of Convection on the Columnar-to-Equiaxed Transition in Alloy Solidification (SUBSA-CETSOL) examines the effects of gravity-driven melt convection and sedimentation or floatation of unattached solid on the columnar-to-equiaxed transition (CET) in the grain structure of metals. CET occurs during metal alloy solidification when round (equiaxed) crystals block the growth of elongated columnar crystals. A better understanding of this complex physical phenomenon is important for predicting and controlling properties of metal alloys, including steel, aluminum alloys and nickel-based superalloys. The investigation compares samples solidified on the International Space Station (ISS) and on Earth.
Extravehicular Activity (EVA) Battery Operations Terminal (EBOT) Installation – Yesterday, the crew continued with installation of the EBOT Battery Cables into the Avionics Rack in the Airlock (A/L). During the install, there was interference with the Moderate Temperature Loop (MTL) supply line and the Battery Stowage Compartment (BSC). Crew was able to move the flexible MTL supply line out of the way and fully insert the BSC into the Avionics Rack. A Failure Investigation Team (FIT) was convened to determine next steps. Today, the crew removed the BSC and reinserted the Battery Stowage Assembly (BSA) to protect the A/L rack. The crew will stow the BSC in the A/L while the ground team troubleshoots the issue.
A/L Adapter Plate (JCAP) and NanoRacks Kaber Plate (STEP) Installation for ISS Experience – the crew installed the A/L Adapter Plate (AKA JEM CLPA Adapter Plate or JCAP) and the NanoRacks Kaber Plate (AKA Slide Table Extension Plate or STEP) in support of the ISS Experience EVA.
US Lab Intermodular Ventilation (IMV) Bypass Duct: Today, the crew completed the US Lab IMV bypass duct installation. This involved installing a Bypass Duct that will run through the LAB to send air from Node 3 directly to Node 2 in order to provide better air mixing across the USOS.
