US Extravehicular Activity (EVA) Battery Charging Discharging Unit (BCDU) 2B2 Replacement Preparations: During periods of insolation, the BCDU extracts power from the primary power bus, conditions this power and charges the batteries. During periods of eclipse, the BCDU extracts power from the battery bus, conditions this power and supplies it to the primary power bus at a voltage regulated to a level set by the MDM. Over the weekend when activating the new Li-Ion 2B2 battery BCDU, the converter close command failed; ground teams have determined that replacing the BCDU with a new spare will restore full functionality to the Channel 2B. Today, the ISS crew completed procedure reviews and EVA tool configuration in preparation for a BCDU 2B2 Remove and Replacement EVA.

T2 Treadmill Maintenance: Today, the ISS crew completed the nominal 6-month maintenance and inspection, which included performing activities such as removing and cleaning closeout panels, inspecting treadmill belt slats and screws, vacuuming inside the rack and around treadmill, cleaning the treadmill filter screen, reinstalling the close-out panels and taking some acoustic measurements. The 6-month maintenance allows the T2 treadmill exercise device to keep operating nominally as well as making note of any wear and tear.

Mobile Servicing System (MSS) Operations: Over the weekend, the Robotic Ground Controllers powered up the Mobile Serving System (MSS) to perform a swap of the Remote Power Controller Modules (RPCMs) in slots S34BE and S03AD in order to recover main power of the Express Logistic Carrier (ELC) #4. The Special Purpose Dexterous Manipulator (SPDM) Arm 1 utilized the Robot Micro Conical Tool 1 (RMCT 1) and extracted the RPCM in slot S03AD on the first pull attempt. Next, SPDM Arm2 using RMCT2 extracted the RPCM in slot S34BE using the new Auto-wiggle technique. Then SPDM Arm 1 using RMCT 1 installed the fully functional RPCM in S34BE slot in a single push maneuver followed by SPDM Arm 2 installing the degraded RPCM in S03AD also in a single push. The robotic RPCM Remove & Replace restored main power to the ELC #4.

Analog-1 (Investigation of the Use of an Advanced Human-Robotic Interface in Enhancing the Performance of Teleoperated Robotic Field Geology): As part of the preparation for the Analong-1 investigation which arrives later, the crew inserted the USB drive into HV4 (hypervisor). Space is such a harsh place for humans and machines that future exploration of the Solar System may involve sending robotic explorers to “test the waters” on uncharted planets before sending humans. The parent METERON project is a European initiative to help prepare for future human-robotic exploration missions to the Moon, Mars, and other celestial bodies. The project is organized around a series of experiments as preparatory steps towards gaining the experience needed, through adaptation of the traditional ways of working, to effectively and efficiently support operations of human and robotic combined elements on a planetary surface.

NutrISS: The crew set up the NutrISS Device and related equipment and executed a Bioelectrical Impedance Analysis (BIA) measurement. In the NutrISS investigation, a periodic assessment of body composition (body weight, fat mass and fat-free mass) during spaceflight aboard the ISS is carried out using a dedicated bio-impedance analysis device to allow for the measurement of long-term energy balance modification over time. Based on this data, it is hypothesized that an adjusted diet maintaining a near-neutral energy balance, and/or increasing protein, intake can limit microgravity-induced bone and muscle loss of crew members.

Payload NAS hard Drive and cable swap: The crew performed the necessary activities to replace a cable and a hard drive. The replacement of the cable is expected to regain a redundant Ethernet path and the hard drive is being replaced due to the number of errors associated with it. The Payload Network Attached Storage (NAS) is a file server with 5 hard drive bays that provides a total of 20 terabytes of raw disk space when used with 4 terabyte hard drives. Among other capabilities, the PL NAS supports user file transfers from their machine via web browser, and allows onboard ISS systems to access a shared folder location on the NAS.

Vection: The crew setup up the appropriate support hardware and performed their VECTION Experiment sessions. Vection is made up of three tasks that test how orientation perception, motion processing, and depth perception are affected by long duration 0g and return to 1g. The objective of the study is to determine to what extent an astronaut’s ability to visually interpret motion, orientation, and distance may be disrupted in a microgravity environment, and how it may adapt, and how it may be changed upon return to Earth. Multiple experimental time points inflight and upon return to Earth allows for the adaptation and recovery process to be investigated.
