Airway Monitoring Experiment: The crew prepared the airlock by removing equipment, transferring and setting up Airway Monitoring hardware and configuring a video camera. This experiment was performed in the US airlock at 10.2 psi pressure with the hatch closed. This is the first time the US equipment lock (as a hypobaric facility) was used for performing utilization. Operations started nominally with the first low Nitric Oxide (NO) Fractional Expired Nitric Oxide (FENO) measurements under ambient pressure. An anomaly occurred when transitioning to the high NO Diffuse Capacity in Lungs Nitric Oxide (DLNO) measurements under ambient pressure. Teams observed the Low NO Analyzer going into an unexpected long warm-up mode after each measurement. Troubleshooting was unsuccessful and no ambient pressure DLNO measurements were performed. In the reduced pressure of 10.2 psi, three of twelve low NO measurements were captured for Virts and none for Cristoforetti. None of the four planned DNLO measurements were collected in the pressurized Airlock configuration. Ground specialists are developing a forward plan.
40 Soyuz (40S) Return Prep: Preparations continue for the upcoming 40S undock and return next week. Two ISS Reboosts have been completed to set up the proper ISS phasing for 40S landing in the southern zone. The crew has also completed a nominal Sokol Suit checkout, parts 1 and 2 of the Soyuz OBT decent drill, Soyuz thruster test, and has begun staging return cargo for loading in the vehicle.
Spare Pump Module (PM) Relocation: Earlier today the Robotics Ground Controllers removed the degraded PM from External Stowage Platform (ESP)2 are are currently working to remove the spare PM from Express Logistics Carrier (ELC)2. Later today, and tomorrow if required, the Ground Controllers will install the degraded PM on the ELC2 and the spare PM will be installed on the ESP2. The purpose of this PM swap is to position the good spare PM in a better location should it be needed for a PM R&R EVA.
