ISS Daily Summary Report – 2/10/2022


Combustion Integrated Rack (CIR): The crew performed steps in support of the multi-part rack reconfiguration from the Advanced Combustion via Microgravity Experiments (ACME) experiment insert to the Solid Fuel Ignition and Extinction (SoFIE) experiment insert.  Specifically, the crew exchanged bottles at Manifold 2 and 4, exchanged the adsorber cartridge, set the CIR valve timers, and disconnected the static mixer hose inside the CIR combustion chamber. SoFIE is a hardware insert for CIR that will enable a wide range of solid-material combustion and fire suppression studies, providing common infrastructure including sample holders, flow control, test sections, external radiant heaters, igniters, and diagnostics for multiple investigations. While SoFIE initially meets the requirements of five investigations, is intended for use by any researchers who propose related solid combustion studies to NASA in the future.

Food Physiology: A diet briefing was attended in support of the Food Physiology investigation. The Integrated Impact of Diet on Human Immune Response, the Gut Microbiota, and Nutritional Status During Adaptation to Spaceflight (Food Physiology) experiment is designed to characterize the key effects of an enhanced spaceflight diet on immune function, the gut microbiome, and nutritional status indicators. These factors are interlinked, but diet is the only one that can be easily and meaningfully altered on Earth or during flight. This investigation aims to document the effect of dietary improvements on human physiology and the ability of those improvements to enhance adaptation to spaceflight.

Grip: In a continuation of the sessions started earlier this week, two sessions of Grip Seated Science 2 were performed. From an upright seated posture, the crew performed experiment tasks looking at friction, discrete (with eyes open/closed), and collisions. 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.

ISS Ham Pass: The crew participated in an ISS Ham pass with Gewerbliche Schulen Donaueschingen, Donaueschingen, Germany. Questions asked by the students included what happens if there is a leak in ISS, opportunities the crew must relax, and what concerns the crew has from living in space. ISS Ham Radio provides opportunities to engage and educate students, teachers, parents, and other members of the community in science, technology, engineering, and math by providing a means to communicate between astronauts and the ground HAM radio units.

Plant Habitat-05: Harvest 3 was performed today, which is around 45 days into the growth cycle of the experiment. The fourth and final harvest is planned around Day 90 of the experiment.  Unlocking the Cotton Genome to Precision Genetics (Plant Habitat-05) cultivates several cotton genotypes that differ in their ability to regenerate into whole plants from undifferentiated masses of cells known as a calli. Cotton is highly resistant to the process of plant regeneration, making it difficult to engineer stable, reproducing plants that have specific or enhanced traits such as drought resistance. The investigation could provide a better understanding of this behavior and a pathway to avert this problem.

Rodent Research-18 (RR-18): The RR-18 experiment continued today with activities including a habitat restock and access unit cleaning. Astronauts returning from space can experience eye problems, along with headaches and blurred vision. Scientists suspect environmental conditions during spaceflight lead to oxidative stress that adversely affects the eye structure and function. Space Flight Environment Induces Remodeling of Vascular Network and Glia-vascular Communication in Mouse Retina (Rodent Research-18) investigates how spaceflight affects visual function, examining changes in the vascular system of the retina, tissue remodeling and cell-cell interactions in mice.

Touching Surfaces: The crew performed a periodic touching of the Touch Arrays which are deployed in five different locations in the US segment of ISS. Previous space research conducted during short-term flight experiments and long-term environmental monitoring on board orbiting space stations (such as MIR or the ISS) suggests that the relationship between humans and microbes is altered in the crewed habitat in space. This interdisciplinary project, Touching Surfaces, aims to investigate novel, laser-structured antimicrobial surfaces onboard the ISS. The realistic testing of the tailor-made nanostructured antimicrobial surface in space allows for the determination of the most suitable design for antimicrobial surfaces for terrestrial applications such as public transportation and clinical settings, as well as future human space mission and habitation design.


Health Maintenance System (HMS) Periodic Health Status (PHS) Evaluations: The HMS monitors crew health, responds to crew illness or injury, provides preventive health care, and provides stabilization and emergency transport between vehicles. Today the crew completed Periodic Health Status (PHS) Evaluations using an otoscope for ear imagery and other tools for measuring and recording the crew’s temperature, blood pressure, pulse, and respiratory rate. 

Health Maintenance System (HMS) Ultrasound 2 Lumbar Spine Scan: The crew performed routine ultrasound scans today to collect data that will help medical researchers characterize the effects of spaceflight on the spine and how spinal alterations leading to back pain and potential injury can be avoided. Ground based pre- and post-flight Magnetic Resonance Imaging (MRI) and high-fidelity ultrasound, combined with in-flight ultrasound, are used to characterize and assign a mission health risk to microgravity-associated spinal alterations for back pain and potential injury.

Environmental Health System (EHS) Total Organic Carbon Analyzer (TOCA): TOCA primarily serves as a third level of redundancy safety control for the Regenerative Environmental Control and Life Support System (ECLSS) Water Processor for potable water by monitoring total organic carbon (TOC) and total inorganic carbon (TIC) concentration levels, a general indication of overall water quality. To check the accuracy of the TOCA calibration, the crew used a sample bag with a known amount of TOC and TIC. The crew recorded this calibration data for tracking and systems analysis. 

Water and Recovery System (WRS) Iodinated Contingency Water Container (CWC-I): The CWC is a soft container with an inner bladder that can store a variety of liquids including humidity condensate, wastewater, and other unique fluids such as Extravehicular Mobility Unit (EMU) wastewater. Iodine is used for disinfection. The crew set up the CWC-I Transfer Station and then activated the Fluid Transfer Pump to transfer fluid to a Water Storage System (WSS) Water Resupply Tank (RST). This assembly utilizes a Microbial Check Valve and Water Check Valve Hose to maintain the potable integrity of the CWC-I.

Dragon / LAB Space Station Computer (SSC) Swap: SSCs are the laptops associated with non-command activities onboard the ISS. Today, the crew moved SSC 10 from Dragon to LAB and moved SSC 20 from LAB to Dragon. SSCs are swapped regularly to ensure that International Procedures Viewer (IPV) backups are applied to SSCs remaining in Dragon for emergency situations.
