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 …
A bright fireball event occurred on Dec. 17 at 8:20:40 PM CST. It started out 52 miles above I-24 just south of Manchester, TN and moved to the northwest at 50,000 mph. The all sky camera lost track of it at an altitude of 23 miles just to the northwest of Shelbyville. Below is a …
External Thermal Control System (ETCS) Loop A Status: Following yesterday’s S1-1 MDM software patch, Flight Controllers continued to perform characterization tests on ETCS Loop A to regain fine temperature control of ETCS loop A. The Node 2 Moderate Temperature Loop (MTL) IFHX is still isolated from ETCS Loop A, resulting in half of the loads …
USOS EVA and Orbital Status: A Program decision was made to pursue USOS EVAs on December 21st, 23rd, and 25th (if required) in order to repair the ETCS Loop A Pump Module. The EVAs will be carried out using EMUs 3010 and 3011. Orbital launch will be delayed until after the beta cutout in January. …
External Thermal Control System (ETCS) Loop A Status: ETCS Loop A is still operating without full temperature control. All Loop A Interface Heat Exchangers (IFHX) remains bypassed and isolated, preventing internal heat rejection on loop A. ETCS Loop B continues to operate nominally. MCC-H continues to perform tests on ETCS Loop A to determine if …
