ISS Daily Summary Report – 3/10/2021


Antimicrobial Coatings Touch: Per standard procedure, the crew touched both the coated and uncoated coupons for this long-term investigation. 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 hardware was powered-on and the area was cleared of stowed items in preparation for a set of crew-minimal operations. In these operations, the Astrobee satellites are guided through various objectives with minimal crew intervention, typically only for recovery of a satellite which has become non-responsive. Astrobee is made up of three 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 accommodate up to three investigations.

Combustion Integrated Rack (CIR)/Advanced Combustion via Microgravity Experiments (ACME): The crew performed the second part of the work needed to reconfigure the ACME chamber insert from Coflow Laminar Diffusion (CLD) support to Cool Flames Investigation with Gases (CFIG) support, which is the next ACME experiment to be performed. Cool diffusion flames were discovered during droplet combustion experiments aboard the ISS in 2012, and this initiated a rapidly growing field of combustion research. A cool flame is one that burns at about 600 degrees Celsius. A typical candle is about two-and-a-half times hotter, burning at around 1,400 degrees Celsius. Most internal combustion engines are designed using computer models that neglect cool flame chemistry, but ignition and flame propagation in engines depend on cool flame chemistry. Cool flame chemistry also has a significant impact on fuel octane and cetane numbers, whose understanding has large economic consequences.

Collapsible Contingency Urinal (CCU): The crew set up the CCU for a 24 hour test session. During the test session the crew uses the CCU and provides feedback in the form of a questionnaire. The CCU is exploration hardware flown to ISS as a technology demo. The approach includes a fractal wetting design that incorporates smart capillary fluidics. This work could have a broad impact on capillary-based fluid management on spacecraft and on Earth.

Grape Microbiota: The crew retrieved the Grape Microbiota hardware from the Polar and set it up to prepare for inspection and initiation of the experiment. Microbes (bacteria, algae, and fungi) that coexist with plants are a key factor influencing fruit size, shape, color, flavor, and yield of fruit for grapes and a variety of other crops. Grape Juice Fermentation in Microgravity Aboard ISS observes the complete process of fermentation in microgravity and measures physical and genetic differences in the microbes involved. Characterizing the differences seen in microgravity could provide a better understanding of how microbes affect their host crops.

JEM Airlock (JEMAL) Preparations for JEM Small Satellite Orbital Deployer (J-SSOD): The crew reconfigured the adapters and other hardware on the JEMAL slide table. This reconfiguration is needed to support the installation of the J-SSOD-16 experiment hardware later in the week. The J-SSOD provides a novel, safe, and small satellite launching capability to the ISS. The J-SSOD is a unique satellite launcher, handled by the Japanese Experiment Module Remote Manipulator System (JEMRMS), which provides containment and deployment mechanisms for several individual small satellites. Once J-SSOD, including satellite install cases with small satellites, is installed on the Multi-Purpose Experiment Platform (MPEP) by crew members, it is passed through the JEM airlock for retrieval, positioning, and deployment by the JEMRMS.

Packed Bed Reactor Experiment – Water Recovery (PBRE-WR): The crew performed a routine inspection for water leakage during the PBRE-WR series of experiments. They did note the washcloth, which is used to catch liberated water, was saturated and replaced it. The ground team reported this was not unexpected since they were performing high flow rate tests at the timePBRE-WR examines flow rates of gas and liquid through a filtering substrate in the space station water processor, replacing oxygen with nitrogen. This investigation could help identify optimum conditions and enhance accuracy of models that predict simultaneous flow of gas and liquid (two-phase flow) in microgravity.

Real-time Protein Crystal Growth Phase II (RTPCG-2): The crew removed the RTPCG-2 samples from Space Automated Bioproduct Laboratory (SABL), observed and photographed the sample wells using the microscope, then returned the samples to SABL. RTPCG-2 demonstrates new methods for producing high-quality protein crystals in microgravity. Previous work has shown that microgravity can sometimes produce high-quality protein crystals that can be analyzed to identify possible targets for drugs to treat disease. RTPCG-2 tests high-quality proteins crystals for detailed analysis back on Earth.


Extravehicular Activity (EVA) Preparations: The crew performed several activities in preparation for the ISS Upgrades 3.5 EVA. The crew swapped Extravehicular Mobility Units (EMUs) 3004 and 3015 with EMUs 3006 and 3009 on the EMU Don/Doff Assemblies (EDDAs), resized EMU 3006 and swapped waist and helmet components with EMU 3015. The crew then installed EMU Long Life Batteries (LLBs) and Metal Oxide (METOX) cartridges to the prime EMUs. A Li-ion Rechargeable EVA Battery Assembly (REBA) was installed on EMU 3009 and HECA was on EMU 3006. Next, the performed a REBA powered hardware checkout for the prime EMUs. Finally, the crew performed EVA tool configurations, reviewed procedures, and participated in a conference with the ground. The ISS Upgrades 3.5 EVA is scheduled for Saturday, March 13th. 

In Flight Maintenance (IFM) Water Processing Assembly (WPA) Waste Water Filter Remove & Replace (R&R): The crew performed an R&R of an expended Waste Water filter in the WPA between the Pump/Separator Orbital Replacement Unit (ORU) and the Waste Water ORU. The WPA was activated after the completion of the R&R. The WPA uses a series of treatment processes to produce potable water from various waste streams generated on the ISS. These treatment processes include particulate filtration, adsorption, ion exchange, catalytic oxidation, and sterilization.
