Change of Command Ceremony and 59S Undock/Landing: Today, the ISS Crew participated in a Change of Command Ceremony during which Luca Parmitano handed over command of the ISS to Oleg Skripochka. Luca Parmitano, Aleksandr Skvortsov and Christina Koch will return to Earth tonight on 59S. Undocking is scheduled for 11:49 PM CT with landing in Kazakhstan scheduled tomorrow at 3:14 AM CT.

Confined Combustion: The crew continued the experiment using acrylic and fabric samples with a combination of black and transparent baffles to ignite and observe combustion results. This project aims to study flame spread in confined spaces, specifically the interactions between spreading flames and surrounding walls. Flame spread in confined spaces (such as buildings and vehicles) may pose a more serious fire hazard than flame spread in open spaces because of acceleration caused by radiative heat feedback from the surrounding walls and a tunnel flow acceleration effect. However, several aspects of flame spread are difficult to study in normal gravity conditions. Gravity-driven buoyancy flow complicates the fire growth process and prohibits a fundamental understanding of the underlying physics. However, in microgravity, buoyancy is eliminated, allowing scientists to better study the physics of flame spread.

Bio-Monitor: The crew completed the 48 hour data measurement session using the Bio-Monitor garment. Data was secured and the garment and support hardware was stowed. Although the ISS is equipped with health and life sciences research tools, the existing instrumentation for continuous and simultaneous recording of several physiological parameters is lacking. To tackle this issue, the Bio-Monitor Commissioning activity tests the Bio-Monitor facility; a wearable garment capable of monitoring relevant physiological parameters for up to 48 hours in a non-invasive and non-interfering way. The physiological parameters which can be monitored consist of heart rate, respiration rate, Electrocardiogram (EKG), skin temperature, peripheral blood oxygen saturation, etc.

Actiwatch Plus: Crewmembers doffed and stowed the hardware. The Actiwatch is a waterproof, nonintrusive, sleep-wake activity monitor worn on the wrist of a crewmember. The device contains a miniature uniaxial accelerometer that produces a signal as the subject moves. The data are stored in nonvolatile memory within the Actiwatch until they are downloaded for analysis.

On-board Training (OBT) Cygnus Robotics Onboard Trainer (ROBoT) Self Study Session: FE-8 and FE-9 completed a session of this training to practice 2 meter, Capture Point (CP) and High Hover (HH) approaches in preparation for NG-13 launch on February 9 and berthing on February 11.

Extravehicular Mobility Unit (EMU) Maintenance: The crew retrieved EMUs 3006 and 3009 and removed the Lower Torso Assembly (LTA) stowage bags. They then installed the bags on EMUs 3004 and 3008. This reconfiguration is in preparation for a planned EVA in April. Currently the crew is performing a full dump and fill on EMUs 3006 and 3009 to meet annual maintenance requirements.

Potable Water Dispenser (PWD) Filter R&R: The crew is R&Ring the PWD filter including cleaning the fan filter areas on the back side of the PWD. This is preventative maintenance that is required every 18 months.
