Treadmill 2 (T2) Status: Over the weekend, the Crew completed the last set of closeout activities in order to restore T2 operations. T2 had experienced connectivity issues between the Station Support Computer (SSC) and the T2 Rack on September 22nd. After extensive troubleshooting by Crew and ground teams, it was determined that a change out of the system’s Data Avionic Unit (DAU) was needed. The DAU change out occurred on September 27th. After the change out, approximately 10 hours of closeout activities remained to restore T2 operations. During the timeframe when T2 was inoperable, the Crew exercised on the Cycle Ergometer with Vibration Isolation and Stabilization (CEVIS).
Zebrafish Muscle: Gerst performed the third water quality measurement of the aquarium water. This experiment asks if the atrophy of muscles under the condition of microgravity also occurs in zebrafish and why their atrophy occurs in the microgravity.
Salivary Markers: Wilmore provided saliva, urine, and blood samples and stored them in cold stowage for the Salivary Markers investigation. The Effects of Long-Term Exposure to Microgravity on Salivary Markers of Innate Immunity (Salivary Markers) investigation involves the collection of blood, saliva, urine and a health assessment on six subjects pre-, in- and post-flight to determine if spaceflight induced immune system dysregulation increases infection susceptibility or poses a significant health risk to crewmembers onboard the ISS.
Drug Metabolism: Gerst performed Drug Metabolism Sample Operations 4 today. The crew removed the C group of BioCells from Commercial Generic Bioprocessing Apparatus-4 (CGBA-4). A sample was then taken from all C group BioCells and placed in the Drug Metabolism Ziplock Bag. The Drug Metabolism Ziplock Bag was then placed in Cold Storage.
Extravehicular Activity (EVA) Preparation: In support of tomorrow’s EVA 27, Wilmore printed and installed Cuff Checklist procedures onto both Extravehicular Mobility Units (EMU). In addition, Gerst and Wiseman performed a functional checkout of the Simplified Aid for EVA Rescue (SAFER). Lastly, Gerst, Wiseman, and Wilmore all reviewed EVA related procedures and conducted a conference with the ground. Hatch opening is set to occur tomorrow morning at 7:15am with ingress back into the Joint Airlock at approximately 12:55pm.
Mobile Servicing System (MSS) Operations: Today, the Robotics Ground Controllers powered up the MSS and maneuvered the Space Station Remote Manipulator System (SSRMS) to the start position for tomorrow’s EVA. They then set up the Mobile Base System (MBS) Payload Orbital Replaceable Unit (ORU) Accommodation (POA) for the release of the failed Pump Module during the EVA. MSS performance today was nominal.
