Pressurized Mating Adapter (PMA)3 Relocation: Yesterday, Robotics Ground Controllers utilized the Space Station Remote Manipulator System (SSRMS) to grapple and relocate PMA3 from Node3 Port to Node2 Zenith. After the relocation, they ungrappled PMA3 and maneuvered the SSRMS in position ready to provide viewing support for EVA 41 (Enhanced Processor Integrated Communications (EPIC) External Multiplexer/Demultiplexer (MDM) Shields), scheduled for March 30th. The PMA3 relocation was needed to configure Node2 Zenith as a future visiting vehicle docking port.

Fluid Shifts Chibis Measurements, Day 1: On March 9th, the 48S subject performed the first of two days of operations in the Russian Segment conducting the Return minus 45 day Fluid Shifts operations, however, due to communication issues with Tracking and Data Relay Satellite System (TDRSS)-275, insufficient data collection occurred. Today, the crewmember repeated the session and donned the Lower Body Negative Pressure (LBNP/Chibis) device while the operator, with ground support in Moscow, assisted in the medical monitoring. Additionally, while the subject was in the LBNP and experiencing the negative pressure (pulling the fluid feetward), the Crew Medical Officer performed Cerebral and Cochlear Fluid Pressure (CCFP) and Ultrasound measurements. Fluid Shifts is a joint NASA-Russian experiment that investigates the causes of severe and lasting physical changes to astronauts’ eyes. Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a lower body negative pressure device is investigated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and eye damage.

Cool Flames Investigation (CFI) Science Runs: Last week ground teams successfully calibrated the CFI Intensified Camera, placing the CIR in a good configuration for operations. This morning, the crew removed the Combustion Integration Rack (CIR) Alignment Guides to isolate the rack. Ground teams then initiated the science run. CFI provides new insight into the phenomenon where some types of fuels initially burn very hot, then appear to go out but continue burning at a much lower temperature with no visible flames (cool flames). Understanding cool flame combustion helps scientists develop new engines and fuels that are more efficient and less harmful to the environment.

Ice Brick Conditioning: The crew ibegan conditioning of 18 of the -32° Celsius Ice Bricks, inserting them into the three Minus Eighty Degree Celsius Laboratory Freezers for ISS (MELFIs). The bricks will be used as thermal mass in MELFI and for future sample return on SpaceX-11.

Extravehicular Mobility Unit (EMU) 3008 Discoloration: During last week’s EVA, EV1 reported yellow discoloration similar to a grass stain on his gloves and equipment. The source of the staining has been identified as coming from the Japanese Experiment Module (JEM) Exposed Facility (JEF) scuff plate. JAXA provided information on the JEF scuff plates material. Ground teams are investigating potential risk to crew and hardware and development of a method for removing the substance. On Sunday, the crew attempted to clean some of the affected hardware with tape and lint free wipes. Ground teams met today to discuss the result of this activity.

U.S. Extravehicular Activity (EVA) #41 EPIC Shields Preparations: In preparation for this Thursday’s planned EVA, the crew performed a procedures review followed by a conference with ground teams. Topics covered included:
