Human Research Facility (HRF) Urine Setup: The crew set up hardware in preparation for repository activities later this week. Repository is a storage bank that is used to maintain biological specimens over extended periods of time and under well-controlled conditions. It supports scientific discovery that contributes to our fundamental knowledge in the area of human physiological changes and adaptation to a microgravity environment and provides unique opportunities to study longitudinal changes in human physiology spanning many missions.

Space Acceleration Measurement System II (SAMS II) Screen Cleaning: As part of the routine periodic maintenance, the crew cleaned lint from the filter screens in the SAMS-II RTS/D1 (Remote Triaxial Sensor Drawer 1) and RTS/D2 locations. 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. Investigators seek to better understand the vibration environment on the ISS.

Nitrogen / Oxygen Recharge System (NORS) Tank Uninstall: Today the crew worked with MCC-H to terminate the transfer of Nitrogen from the NORS Recharge Tank to the ISS Airlock Nitrogen Tanks. As part of the activity, they removed the fill hose, regulator, then uninstalled and stowed the tank for return on a future cargo vehicle.

Compound Specific Analyzer – Combustion Products (CSA-CP) Sample Pump Failure: During a scheduled inspection, the crew found that one CSA-CP Sample Pump was failed. The Sample Pump is needed to obtain CSA-CP samples at fire ports. Currently there is only one functional Sample Pump on ISS. Ground teams are working to manifest a spare pump onboard an upcoming cargo vehicle.

Intra-Module Ventilation (IMV) Measurements: Yesterday, the crew took periodic measurements of the airflow at IMV ducts in several locations, including Russian Segment to Node 3, Node 3 to Cupola, Airlock to Node 1, Lab to Node 2, Node 2 to Lab, Oxygen Generation Assembly (OGA) inlet and Node 3 to BEAM. Teams are currently reviewing the data and will request cleaning if the airflow measurements are below pre-defined limits.
