NASA Space Station On-Orbit Status 12 August 2019 - Stem Cells and Testing the Printing of Human Tissue

The Expedition 60 crew kicked off the workweek exploring stem cells and testing the printing of human tissue on the International Space Station.

The astronauts are also gearing up for a spacewalk planned for next week.

Operations continue inside the orbiting lab's new BioFabrication Facility today. Astronaut Nick Hague printed more human tissue samples Monday and stowed them in an incubator to observe and promote their cellular growth.

Flight Engineer Luca Parmitano of the European Space Agency set up the Life Science Glovebox in the Kibo laboratory module and researched the properties of stem cells. The space-based Micro-15 experiment is helping scientists understand stem cell differentiation better than ground-based studies. Results may provide therapeutic insights into ailments affecting humans on Earth and in space.

Early this morning, Parmitano joined NASA astronaut Andrew Morgan for hearing tests. Scientists are measuring how the microgravity environment and the acoustic levels of the station affect a crewmember's hearing before, during and after a mission.

Morgan then partnered up with astronaut Christina Koch in the afternoon to configure spacewalking tools and spacesuit components. Morgan will follow lead spacewalker Nick Hague out of the Quest airlock hatch on Aug. 21 for a six hour and 30 minute spacewalk. The duo will install the International Docking Adapter-3 designed to receive new commercial crew vehicles from Boeing and SpaceX.

Cosmonauts Alexey Ovchinin and Alexander Skvortsov spent their morning learning how the gastrointestinal system adapts to long-term spaceflight. The duo performed ultrasound scans of their gut before and after eating breakfast. Ovchinin then packed gear for return on a future Soyuz landing as Skvortsov checked Russian video and photography gear.

On-Orbit Status Report

Acoustic Diagnostics: The crew completed a questionnaire and used an Acoustic Monitor to measure the ambient background noise to detect otoacoustic emissions (OAEs) which are caused by the motion of the inner ear sensory hair cells as they energetically respond to auditory stimulation. The investigation tests the hearing of ISS crew members before, during, and after flight. This study assesses the possible adverse effects of noise and the microgravity environment aboard the ISS on human hearing. The investigation compares the relationship between the detection of otoacoustic emissions, sounds naturally generated from within the inner ear, and hearing loss levels when exposed to noisy environments.

BioFabrication Facility (BFF): The crew performed the cassette installation/removal and the syringe swaps in support of the second science print with cells. The printed tissue will remain in the BFF until it is transferred to the thermally-controlled ADvanced Space Experiment Processor (ADSEP). The BFF is dedicated to manufacturing human organs and tissues in space, primarily for use by patients on Earth. Besides printing tissue, the BFF also can help maintain the health of deep space exploration crews by producing food and personalized pharmaceuticals on demand.

CASIS PCG 19: The crew transferred 3 vials to the MELFI. Each vial had been incubating at different temperatures for two weeks. This investigation seeks to understand the stability of monoclonal antibody formulations in microgravity. When these formulations degrade and exceed their shelf life, they must be discarded. This leads to increased cost and reduces the areas of the world where the formulations can be offered to patients. By storing formulations in microgravity, it may be possible to see additional processes that lead to degradation. Researchers hope that an understanding of the degradation process could lead to methods of slowing the degradation down.

Micro-15: The crew injected media into the culture bags and placed the bags into SABL for incubation. The goal of this investigation is to better understand the effects of gravity on the differentiation of mammalian cells using 3-D cultures of induced pluripotent stem (iPS) cells. Past flight experiments and ground-based simulations have demonstrated that microgravity influences gene expression, cell proliferation, and differentiation in stem cells but the mechanism behind these observations is not clearly understood. This study investigates how exposure to microgravity fundamentally alters cell regulation and how these changes can affect the timing, progression, and outcomes of cell differentiation.

Materials Science Laboratory (MSL): The crew swapped the MSL gas supply drawer and performed successful leak checks. The MSL is used for basic materials research in the microgravity environment of the ISS. The MSL can accommodate and support diverse Experiment Modules. In this way many material types, such as metals, alloys, polymers, semiconductors, ceramics, crystals, and glasses, can be studied to discover new applications for existing materials and new or improved materials.

Space Acceleration Measurement System-II (SAMS-II): The crew cleaned the SAMS RTS/Drawer1 and RTS/Drawer2 screens. SAMS-II is an ongoing study of the small forces (vibrations and accelerations) on the ISS resulting from the operation of hardware, crew activities, dockings and maneuvering. Results generalize the types of vibrations affecting vibration-sensitive experiments and structural life of ISS. Investigators and Structural Analysts seek to better understand the vibration environment on the ISS using SAMS-II data and assessing station loads and dynamics.

Standard Measures: The crew completed a Body Survey using the Data Collection Tool on an SSC and collected body samples and stowed samples MELFI. The aim of the investigation is to ensure consistent capture of an optimized, minimal set of measures from crewmembers until the end of the ISS Program in order to characterize the adaptive responses to and risks of living in space. Among other things, the ground teams perform analyses for metabolic and chemistry panels, immune function, microbiome, etc. These measures populate a data repository to enable high-level monitoring of countermeasure effectiveness and meaningful interpretation of health and performance outcomes, and support future research on planetary missions.

Microgravity Experiment Research Locker Incubater (MERLIN) 2: On Saturday, the MERLIN2 unit was powered off by a Utility Interface Panel (UIP) Circuit Breaker (CB) trip on the Galley Rack. Contents of MERLIN 2 were moved following a circuit breaker trip. Engineering teams will meet to discuss a forward troubleshooting plan.

International Docking Adapter (IDA)3 Extravehicular Activity (EVA) Preparations: In preparation for the IDA3 EVA currently planned for no earlier than August 21, the crew completed the following:

D5 camera configuration and setup
EVA tool configuration
Waste Hygiene Compartment (WHC) Piping Remove & Replace (R&R): Today the crew attempted to replace the WHC piping between the Dose Pump and the Pump Separator. During the R&R, the crew experienced an issue mating the connection between the WHC piping and the Urine Receptacle at the Insert Filter location. The crew attempted both spare WHC piping units on board, an old Urine Receptacle hose as well as multiple insert filters with the same result. The crew described the issue as the connector on the new WHC piping was slightly too small for the Urine Receptacle connection. Based on the troubleshooting and descriptions provided, ground teams directed the crew to reinstall the old WHC piping and triple bag the two spare WHC piping units. The current, old WHC piping that was reinstalled expired today. Teams agreed with the forward plan to reinstall and run on the expired WHC piping until a forward plan for installing a new WHC piping unit is determined.
