ISS Daily Summary Report – 12/23/2019

CBEF-L (Cell Biology Experiment Facility – Left) configuration change: The crew worked on steps to change the CBEF-L configuration from ‘G’ (sample tray and centrifuge) to ‘F’ (large centrifuge), but were not able to accomplish all the tasks within the time allocated.  The ground is working on plan revisions to accommodate the tasks.  CBEF-L is a new JAXA subrack facility, which is an upgraded facility of the original Cell Biology Experiment Facility (CBEF) currently aboard the International Space Station (ISS). CBEF-L provides new capabilities with additional new resources such as Full High Definition video interface, Ethernet, 24 VDC power supply, and a larger diameter centrifugal test environment. By using the original CBEF and CBEF-L as one facility for the same experiment, the payload user is provided with an upgraded experimental environment that can handle the processing of more experimental samples for a wider array of experiments.

Confined Combustion setup: The crew set up the experiment hardware in the MSG Work Volume to support the Confined Combustion experiment.  Confined Combustion examines the behavior of flame as it spreads in differently-shaped confined spaces in microgravity.  Flame spread observations are translated into mathematical models for use in understanding the results and applying them to areas with different shapes.  In a recent NASA project (Saffire), a large-scale flame spread investigation shows that flames spread more slowly in a large confined space than in a smaller space even if all other environmental conditions are the same (oxygen, pressure, flow speed, etc.). The faster flame spread in smaller chambers is suspected to be due to a combination of thermal expansion during combustion and tunnel flow acceleration. Radiation heat feedback from chamber walls may also be a factor.

Fluid Shifts Chibis ops: The crew performed tasks associated with Fluid Shifts imaging with Chibis. Fluid Shifts is a NASA investigation, divided into Dilution Measurements, Baseline Imaging, and Imaging with Chibis. The Chibis hardware is used to perform the Lower Body Negative Pressure (LBNP) part of the experiment. The Fluid Shifts experiment investigates the causes for severe and lasting physical changes to astronaut’s eyes.  Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a LBNP device is being evaluated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and prevention of eye damage.

Food Physiology: The crew participated in a diet briefing with the Principal Investigator for the 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.


Internal Thermal Control System (ITCS) Sampling: Today, the ISS crew completed the ITCS fluid sampling procedure.  The crew accessed the ITCS sampling adapters and took samples of the ITCS fluid from the Lab, Node 2, Node 3 and JEM module. ITCS sampling is used to analyze the current level of NH3 within an ITCS water loop to determine the rate of attrition of OPA within the coolant or whether or not there is an NH3 micro fissure leak across an IFHX.

Carbon Dioxide Removal Assembly (CDRA) Snorkel Removal:  The ground teams have been performing at Detailed Test Objective (DTO) that examines using the newly installed CDRA Snorkel device to prevent water bypass into the CDRA device.  Today the ISS completed the removal the CDRA Snorkel and USOS Endoscope (S/N 1002) from the LAB1P6 CCAA Heat Exchanger. These were installed to perform a test of the CDRA Snorkel hardware, but will be removed while the test data is analyzed.

Mobile Servicing System (MSS) Operations: Overnight, Robotic Ground Controllers performed a walkoff and base change to the Node 2 Power Data Grapple Fixture (PDGF). The Space Station Remote Manipulator System (SSRMS), then captured the Special Purpose Dexterous Manipulator (SPDM) PDGF. MSS was positioned over the Dragon trunk and the ROBOs maneuvered the SPDM Arm 2 to stow the empty Battery Charge Discharge Unit (BCDU) Flight Support equipment (FSE) Flight Releasable Attachment Mechanism (FRAM) in the Dragon trunk. Once completed, the Ground Controllers commanded the SPDM Arm2 to release the FRAM fixture and back the robotic system away from the trunk. Finally, MSS was parked.

Boeing CST-100 (Starliner) Status: The uncrewed OFT mission completed a successful launch; however, Starliner experienced an issue with the on-board Mission Elapsed Time (MET) data resulting in an off-nominal Orbit Insertion burn. This anomaly prevented the spacecraft from docking with the ISS. The Starliner spacecraft landed at White Sands Space Harbor in New Mexico on Saturday at 6:58 a.m. CST, within the anticipated landing zone.
