ISS On-Orbit Status Report

Node 3 Waste and Hygiene Compartment (WHC) Photos:  This morning, the crew removed the WHC Kabin, took photographs of surrounding areas, and then replaced the WHC Kabin. These high-resolution, high-quality photos of seat track locations in the vicinity of the WHC and Node 3 Mid-Bay will be analyzed by teams on the ground.  These analyses …

Extravehicular Mobility Unit Loop Scrub:  Today, the crew configured Extravehicular Mobility Unit (EMU) suits 3003 and 3008 for loop scrubbing.  Once the scrubbing activity was complete, they reconfigured hardware and performed iodination of Ion Filters for both suits. A sample of the water was obtained after the loop scrub activity to determine the effectiveness of …

Lighting Effects:  A 51S crewmember conducted a Visual Performance Test by stowing the hardware in their crew quarters, setting the light to the correct mode, turning all other light sources in the crew quarters off, and performing a Numerical Verification Test and a Color Discrimination Test. The completed tests were photographed and downlinked. The Lighting …

USOS Extra Vehicular Activity (EVA) #46:  Randy Bresnik (as EV1) and Joe Acaba (as EV2) successfully performed US EVA #46 with a Phased Elapsed Time (PET) of 6 hrs 49 min. The primary goals of the EVA were to Remove and Replace (R&R) a fuse in the Special Purpose Dexterous Manipulator (SPDM) Enhanced ORU Temporary …

Circadian Rhythms:  Yesterday a crewmember instrumented themselves with Thermolab Double Sensors and mounted the Thermolab Unit to their belt, which began 36 hours of monitoring for the Circadian Rhythm investigation.  Circadian Rhythms investigates the role of synchronized circadian rhythms, or the “biological clock,” and how it changes during long-duration spaceflight. Researchers hypothesize that a non-24-hour …

Miniature Exercise Device (MED-2):  Today crewmembers set up cameras in Node 3 to capture video from multiple views of the Advanced Resistive Exercise Device (ARED) and MED-2 hardware.  They also applied body markers, and performed exercises before transferring the video for downlink.  The ISS’s exercise equipment is large and bulky, while the MED-2 aims to …

68 Progress (68P) docking:  Saturday morning, 68P launched from Baikonur after a two day delay.  This morning, 68P docked successfully to DC1 nadir, bringing supplies to the ISS. JAXA Protein Crystal Growth (PCG) #13 Installation:  Following the docking of 68P,  a crewmember stowed two canister bags containing protein samples in the JAXA Freezer-Refrigerator Of STirling …

Advanced Nano Step Troubleshooting: Today the crew successfully completed troubleshooting operations by retrieving the Advanced Nano Step cartridge from the Solution Crystallization Observation Facility (SCOF) to access and adjust the position of the cell stage, due to movement issues during the sample observation.  JAXA’s Advanced Nano Step experiment investigates the relationship between impurity incorporation mechanisms …

68P Launch and Dock Delay:  68P was planned for launch at 04:30 AM Central time, but the launch was aborted during final countdown.  Russian teams are looking into the cause of the abort.  The next launch opportunity is Saturday morning at 03:47 AM Central, with docking two days later on Monday morning. Multi-Omics Sample Collections: …

NeuroMapping: Today two 52S crewmembers set up the NeuroMapping hardware and performed their Flight Day 30 tests in “strapped in” and “free floating” body configurations. During the test, the crewmembers executed three Behavioral Assessments: mental rotation, sensorimotor adaptation, and motor-cognitive dual tasking. The NeuroMapping investigation studies whether long-duration spaceflight causes changes to brain structure and …
