Food Acceptability: The crew completed a Food Acceptability Survey using the Data Collection Tool on an available SSC (Station Support Computer). This investigation seeks to determine the impact of repetitive consumption of food currently available from the spaceflight food system. Results will be used in developing strategies to improve food system composition to support crew health and performance on long duration missions.

Cerebral Autoregulation (CA): In preparation for a future CA data collection, the crew performed the appropriate cable reconfiguration. As the body’s most important organ, the brain needs a strong and reliable blood supply, so the brain is capable of self-regulating blood flow even when the heart and blood vessels cannot maintain an ideal blood pressure. The Cerebral Autoregulation investigation tests whether this self-regulation improves in the microgravity environment of space.

Mouse Mission-5 (MM-5) prep: In preparation for MM -5, the crew Installed Mouse Habitat Cage Unit (one) to the Cell Biology Experiment Facility-Left (CBEF-L) Incubator Unit (IU) and removed Mouse Habitat Cage Unit (three) from CBEF-L IU. JAXA Mouse Habitat Unit-5 (MHU-5) examines the effects of partial G on mice using the JAXA-developed mouse habitat cage units (HCU) that can be installed in the newly developed Centrifuge-equipped Biological Experiment Facility-L (CBEF-L) on the ISS. Stress caused by partial G may alter gene expression in cells of the body. The investigation analyzes any such alterations and their possible effects on development of germ cells, which carry genetic information and expression to subsequent generations.

Systems:

P6 Battery Extravehicular Activity (EVA) Operations: Following a successful P6 Battery Channel 4B EVA#3, the ISS crew participated in a debrief conference with the ground team specialists providing the ground team with valuable feedback on the EVA processes. The crew also performed the Extravehicular Activity Mobility Unit (EMU) battery charging and Metox regeneration activities, both of which restore the EMU suits for the upcoming EVA. In addition, the crew completed some preparatory tasks for the next P6 Channel Battery EVA#4 including procedure reviews along with Space Station Remote Manipulator System (SSRMS) practice procedures.

Columbus Cycle 15 Software Transition: Today, the crew supported the preparation for the Columbus Module software transition by rotating the Human Research Facility (HRF2) rack and installing an upgraded Mass Memory Unit (MMU). The crew removed the MMU MkI and replaced it with the upgraded MMU MkII; the new MMU has the Cycle 15 Software already installed. This completed the second part of a two part MMU Remove and Replace (R&R) that transitions the Columbus Module Software to Cycle 15.
