Gloves photos, and then removal of gloves and helmets
(Scott reported he has some trouble with his right earphone)

EVA-47 Concludes! Seven Hours and 24 Minutes in duration.

ARTICLE:
https://www.nasaspaceflight.com/2018/01/spacewalkers-second-robotic-arm-maintenance-iss/  - by Pete Harding
.

"With the SSRMS maneuvered into position near the ESP-2 worksite, the Camera/Light Pan/tilt Assembly (CLPA) was removed from LEE-B and installed onto the spare LEE, which did not have a CLPA pre-installed."

I believe it is a CLA (Camera Light Assembly) on the LEE. It does not pan.

Great work on the EVA coverage.

Many thanks

ISS Daily Summary Report – 1/23/2018
 

USOS Extra Vehicular Activity (EVA) #47:  Today, Mark Vande Hei (as EV1) and Scott Tingle (as EV2) successfully completed USOS EVA #47 with a Phased Elapsed Time (PET) of 7 hrs 24 min. The primary goal of the EVA was to swap the Latching End Effector (LEE) from the Space Station Remote Manipulator System (SSRMS) B side with the LEE that was stowed as a spare on the External Stowage Platform 2 (ESP-2), while also moving a Worksite Interface Fixture (WIF) adapter and Camera Light Assembly (CLA) between those LEEs.  A state command error was seen during powerup of the new LEE-B on the primary string. The EVA crew demated and remated the connectors, and ground teams were able to power up nominally on the secondary string but still received the state command error on the primary string. Ground teams continue troubleshooting to address the issues with the primary string.

L2 ISS status says they are going to swap the LEEs back on the next EVA (assuming they can't find a fix between now and then, but the wording was they will be swapping back out) :(

The question during press conference questioning whether the LEE would work properly after spending over a decade stored outside proved to be prophetic...
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

Well to be fair, the other LEE's have been stored out in space for just as long (attached to the SSRMS), as have so many other electrical devices that have also failed. Of course they still don't know the issue, and a visual inspection of the electrical connectors might show something (like FOD)

International Space Station officials have postponed Monday’s spacewalk to swap latching end effectors (LEEs) on the Canadarm2 robotic arm. The decision was made after the Canadian Space Agency (CSA) and its robotics specialist team developed a diagnostics software patch confirming an anomaly noted in a primary communications string on the spare end effector installed during a prior spacewalk Jan. 23 was not hardware related, and can be corrected through the implementation of software. A confidence test verifying the software upgrade was successfully completed Saturday night.

During its initial power up after last Tuesday’s spacewalk swap, the spare latching end effector did not communicate as expected on the primary string, but did so on its backup communications string. As a result, Monday’s spacewalk by Mark Vande Hei of NASA and Norishige Kanai of the Japan Aerospace Exploration Agency (JAXA) was replanned to return the original latching end effector to the arm in place of the spare. But the software solution confirmed on Saturday will not require the spacewalkers to venture out on Monday.

The original spacewalk by Vande Hei and Kanai to bring an end effector inside the station removed from the arm during a spacewalk last October, and install the end effector removed last Tuesday on the mobile base system rail car on the station’s truss, is expected to be executed by the two crew members in mid-February.

ISS Daily Summary Report – 2/08/2018

Latching End Effector B (LEE-B) Commissioning: Yesterday evening, Robotic Ground Controllers performed new Latching End Effector B (LEE-B) commissioning steps.  This consisted of performing LEE B checkouts, maneuvering the Space Station Remote Space Station Remote Manipulator System (SSRMS) to capture the Special Purpose Dexterous Manipulator (SPDM) Power Data Grapple Fixture (PDGF) with LEE-B, verifying SPDM power up on LEE-B on both the SSRMS Prime and Redundant Payload Power Strings.  They also switched the SSRMS base from LEE-A to LEE-B and back to LEE-A.  At the completion of these steps, the Robotic Ground Controllers released LEE-B from MBS PDGF4 and maneuvered to a park position in preparation for USOS EVA 48.

Software fix uploaded and seems to have been successful.
