Node 3 Carbon Dioxide Removal Assembly (CDRA) Leak Check Status: Yesterday, Kelly located a likely source of the leak in N3 CDRA during the inspection with Ultrasonic Leak Detector (ULD - "UL101 Ultrasound Detector"). This leak was discovered following the installation of the new CDRA beds back in May of this year. Ground teams will be reviewing the data and developing a leak repair task for the crew to perform in the future. Overnight, the N3 CDRA was activated and operated nominally following the replacement of Air Selector Valve (ASV) 104, and it is actively scrubbing Carbon Dioxide (CO2). ASV Spares Correction - Yesterday's Daily Summary Report stated that the next CDRA ASV spare is expected to arrive on HTV-5 which is incorrect. The next pristine spare is expected to arrive NET Orb-4. There are two degraded spares that can be cleaned on-orbit if needed.
