ISS Daily Summary Report – 3/13/2020

ISS HAM pass: The crew participated in an ISS HAM pass with South Australia Wing, Parafield, South Australia.  Questions included how the crew judges direction in space, how astronaut training in the pool compares to the actual activities performed in space, and how long it takes to get to the ISS.  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.

MVP2 cell-03: The crew installed Nutrient Tubesets into the Emory Modules, inserted the Emory Modules into MVP-02 and prepared for cell insertion on Saturday. This project will study the generation of cardiomyocytes, specialized heart muscle cells, for use in research and clinical applications. Specifically, the team is studying the differentiation of these heart cells from induced pluripotent stem cells (iPSCs), adult cells that have been altered to reinstate characteristics of natural stem cells. Simulated microgravity studies have allowed the team to increase the yield, purity, and survival of cardiomyocytes derived from iPSCs, and true spaceflight conditions are expected to further enhance these effects. Understanding how microgravity improves cardiomyocyte differentiation will enable the team to create clinically relevant heart tissue for use in regenerative medicine, disease modeling, and drug discovery.

OsteoOmics-2: Using the Life Science Glovebox (LSG), the crew was planned to perform the fixation (preservation) operations on the remaining BioCell in BioCell Habitat 2 but it was contaminated.  The ground team is assessing the possible source of the contamination which has affected the majority of the 24 total BioCells in the 4 habitats.  Millions of Americans experience bone loss, which results from disease or the reduced effects of gravity that can occur in bed-ridden patients. OsteoOmics tests whether magnetic levitation accurately simulates the free-fall conditions of microgravity by comparing genetic expression osteoblastic cells, a type of bone cell, levitated in a high-field superconducting magnet with cells flown in low-Earth orbit. This information helps scientists determine the molecular and metabolic changes that take place in magnetic levitation and real microgravity.

Phage Evolution: The crew performed SABL removals and MELFI insertions to support the last part of the Phage Evolution investigation.  Evolution of New Phage-Bacteria Interactions from Exposure to Space Environment (Phage Evolution) examines the effects of microgravity and radiation exposure on phage and bacterial host interactions, including phage specificity for a bacterial host and host resistance to specific phages. Bacteriophages, or phages, are viruses that invade and destroy targeted bacteria without harming human cells or the body’s beneficial bacterial population. Characterizing microgravity’s effects on phages could lead to improved therapies that provide alternative treatments for antibiotic-resistant infections. 


Urine Processing Assembly (UPA) Status: Following UPA issues last Sunday which indicated a seizing of the drive train and imminent hard failure of the Pressure Control and Pump Assembly (PCPA), engineering teams concluded that the PCPA was near end-of-life and recommended replacement of the unit with an available on-orbit spare. The crew completed the R&R, however, the UPA faulted out due to a PCPA high current signature during initial startup. Two additional restarts were attempted with similar fault signatures. Ground teams are evaluating the data and forward plan.

Extravehicular Mobility Unit (EMU) In-Flight Refill Unit/Fluid Pumping Unit (FPU) Sampling: To satisfy maintenance requirements for on-orbit stowage, the crew dumped and filled EMU 3004 feedwater tanks using iodinated water from a Contingency Water Container – Iodinated (CWC-I). After a recharge, a small quantity was dumped from the feedwater tanks to provide ullage for condensate collection during the next EMU prebreathe. In addition, this procedure includes steps for taking two water samples from the IRU: the first after the full EMU dump and the second 4 hours later.
