EVA-46 coming to an end. Another successful EVA, the third of a triple spacewalk series. LEE replaced. New cameras and lots of get-aheads.

Great HD views of airlock ingress as @AstroKomrade & @AstroAcaba call it a day. Once inside, both will hook their suits up to ISS power/cooling, deactivate the sublimators and close the hatch. http://spaceflight101.com/iss/live-spacewalk-coverage/ ...

That was nice. Randy sends a happy retirement message to the chief of the EVA, Robotics and Crew Systems Division, Sue Rainwater. And she's in tears over it.

Quest airlock repress is complete & the spacewalkers are being moved inside, though the first order of business was bagging two of the tool bags containing external elements to avoid contamination by paint flakes and the like.

Expedition 53 Spacewalk Successfully Comes to an End
Posted on October 20, 2017 at 2:49 pm by Melanie Whiting.



Expedition 53 Commander Randy Bresnik and Flight Engineer Joe Acaba of NASA completed a 6 hour, 49 minute spacewalk at 2:36 p.m. EDT. The two astronauts installed a new camera system on the Canadarm2 robotic arm's latching end effector, an HD camera on the starboard truss of the station and replaced a fuse on the Dextre robotic arm extension.

Спойлер

The duo worked quickly and were able to complete several "get ahead" tasks. Acaba greased the new end effector on the robotic arm. Bresnik installed a new radiator grapple bar. Bresnik completed prep work for one of two spare pump modules on separate stowage platforms to enable easier access for potential robotic replacement tasks in the future. He nearly finished prep work on the second, but that work will be completed by future spacewalkers.

This was the fifth spacewalk of Bresnik's career (32 hours total spacewalking) and the third for Acaba (19 hours and 46 minutes total spacewalking). Space station crew members have conducted 205 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 53 days, 6 hours and 25 minutes working outside the station.

ISS Daily Summary Report – 10/19/2017

Circadian Rhythms:

Спойлер

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 cycle of light and dark affects crew members' circadian clocks. The investigation also addresses the effects of reduced physical activity, microgravity and an artificially controlled environment. Changes in body composition and body temperature, which also occur in microgravity, can affect crew members' circadian rhythms as well. Understanding how these phenomena affect the biological clock will improve performance and health for future crew members.

Fine Motor Skills (FMS):

Спойлер

Today a 51S crewmember completed a Flight Day 85 FMS session which was executed on a touchscreen tablet, where the subject performs a series of interactive tasks. The investigation studies how fine motor skills are affected by long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth gravity. The goal of FMS is to answer how fine motor performance in microgravity trend/vary over the duration of a six-month and year-long space mission; how fine motor performance on orbit compares with that of a closely matched participant on Earth; and how performance trends/varies before and after gravitational transitions, including the periods of early flight adaptation, and very early/near immediate post-flight periods.

Space Headaches:

Спойлер

The crew completed the weekly questionnaire for the ESA Space Headaches investigation. The Space Headaches investigation collects information that may help in the development of methods to alleviate associated symptoms and improvement in the well-being and performance of crewmembers in space. Headaches during space flight can negatively affect mental and physical capacities of crewmembers that can influence performance during a space mission.

USOS Extra-Vehicular Activity (EVA) #46 Preparations:

Спойлер

Today the crew conducted a review of EVA procedures and a conference with ground teams. They also inspected tethers, configured tools, printed cuff checklists, and prepared the equipment lock in preparation for tomorrow's EVA. The goals of USOS EVA #46 include Removal and Replacement (R&R) of the Latching End Effector (LEE) A Camera Lens Assembly (CLA).

Tablet Updates:

Спойлер

As part of the ongoing efforts to update the operating system on the onboard tablets, the crew performed steps to update and configure those tablets.

Remote Power Control Module (RPCM) P12B-B R&R:

Спойлер

Wednesday morning, ground teams completed the robotic activities to swap RPCM P12B-B with P13A-G. On Monday night RPCM P12B-B was extracted and installed into empty truss slot P11A-D and the replacement RPCM was removed fr om slot P13A-G, however it could not be ins erted in to the P12B-B at that time. Robotics activities resumed on Tuesday afternoon and teams were able to successfully install the replacement RPCM in the P12B-B slot after 47 wiggle and push attempts. The new P12B-B RPCM powered up nominally. Ground teams then removed the failed RPCM from the P11A-D truss slot and relocated it to the P13A-B slot successfully. The power up of the P13A-G RPCM was also performed nominally. This completes the RPCM swap activities.

JEM Airlock (A/L) Reconfiguration:

Спойлер

Today, the crew removed the MBSU from the JEM A/L wh ere it had been stowed after the I-Level maintenance was performed in early September. The Kaber plate and adapter plate were then installed on the A/L slide table in preparation for installation of the KE2M satellite on Monday. After KE2M and SIMPL, another JEM A/L-deployed satellite, are deployed next week, the MBSU will be returned to the JEM A/L for transfer and installation externally at External Stowage Platform 2 (ESP2).

External Robotics Operations:

Спойлер

Overnight, robotics ground controllers stowed the Special Purpose Dexterous Manipulator (SPDM) and configured the SSRMS to be in position for the EVA tomorrow. The SSRMS is now based on LEE B, at Mobile Base System (MBS) Power Data Grapple Fixture 4 (PDGF), Worksite 6. LEE A is ready to receive a new LEE CLA.
