Combustion Integrated Rack (CIR) Hardware Replacement: FE-3 Hopkins used the Maintenance Work Area (MWA) for restraining the Multi-user Droplet Combustion Apparatus (MDCA) Chamber Insert Assembly (CIA) while he installed fuel reservoirs, replaced two igniter tips and exchanged manifold bottles to prepare for future operations. ISS InterModule Ventilation (IMV) Airflow Measurement: In support of monitoring the …
Spinal Ultrasound Scan Operations: FE-3 Hopkins, with assistance from the ultrasound operator FE-5 Mastracchio and remote guidance from the ground team, performed the second of his three planned spinal ultrasound scan sessions onboard the ISS. This investigation aims to characterize microgravity-associated spinal alterations during and after spaceflight. Results from this research will be used to enhance crew …
Russian EVA 37: Kotov (EV1) and Ryazansky (EV2) performed RS EVA 37 with a duration of 8 hours and 7 minutes. During the EVA Hopkins was isolated in the MRM-2/36S while Tyurin, Mastracchio, and Wakata had access to all modules forward of the SM / DC1. Tasks completed during the EVA included: Installation of Yakor …
Post-EVA Operations: Flight Engineer (FE)-5 Mastracchio and FE-3 Hopkins performed nominal post-EVA maintenance on the Extravehicular Mobility Unit (EMU) suits. In addition, samples from the Liquid Cooling and Ventilation Garments (LCVG) were transferred into bags to be returned to the ground for analysis. These samples will support the EMU 3011 water in the vent loop …
USOS Extravehicular Activity (EVA) #25: Michael Hopkins (EV1) and Rick Mastracchio (EV2) performed USOS EVA 25 on December 24, 2013. This EVA was the second of two EVAs to replace the degraded S1 Pump Module (PM) that control External Thermal Control System (ETCS) Loop A with a spare PM. Hopkins attached the four ammonia lines …
US Extravehicular Activity (EVA) 25 Prep: The USOS crew is scheduled for a half-duty day today in advance of tomorrow’s EVA. FE-3 Hopkins and FE-5 Mastracchio continued their preparation for the second Pump Module (PM) Remove and Replace (R&R) EVA, scheduled for Tuesday, December 23. The crew has terminated the battery charging, configured the tools …
Extravehicular Activity (EVA) Mobility Unit (EMU) Resize: Following yesterday’s EVA, the feed water switch on EMU 3010 was inadvertently switched on for 2-3 seconds. EMU suit 3010 has been declared no-go until proper drying can be performed due to concerns of water entering the sublimator. Today, FE-3 Hopkins and FE-5 Mastracchio resized their suits such …
USOS Extravehicular Activity (EVA) #24: Flight Engineer (FE)-5 Mastracchio and FE-3 Hopkins successfully completed a 5 hour and 28 minute EVA. The crew was able to remove the degraded pump module, install the PM jumper and stow the degraded PM on the Payload ORU Accommodation (POA). FE-6 Wakata provided Space Station Remote Manipulator System (SSRMS) …
Extravehicular Activity (EVA) preparation: Flight Engineer (FE)-3 Hopkins, FE-5 Mastracchio, and FE-6 Wakata performed a final tool gather and audit needed for tomorrow’s planned EVA. The crew also reviewed procedures associated with the Ammonia decontamination protocol, EVA timelines, and a briefing package for Long Duration Tie Down Tether (LDTDT) configuration. EVA #24 hatch open is …
External Thermal Control System (ETCS) Loop A Status: All Interface Heat Exchangers (IFHXs) are still bypassed and isolated from ETCS Loop A, resulting in half of the loads in the Node 2, JEM and Columbus modules to remain powered off. Extravehicular (EVA) Preparations: In preparation for Saturday’s planned EVA, Flight Engineer (FE)-5 Mastracchio completed pre-EVA …
