NASA Space Station On-Orbit Status 23 January 2018 - First Spacewalk of 2018 Completed.

Expedition 54 Flight Engineers Mark Vande Hei and Scott Tingle of NASA completed the first spacewalk this year at 2:13 p.m. EST, lasting 7 hours, 24 minutes. The two astronauts replaced a Latching End Effector (LEE) on the station's robotic arm, Canadarm2.

There are two redundant end effectors on each end of the arm used to grapple visiting vehicles and components during a variety of operational activities. The spacewalk was the 206th in support of space station assembly and maintenance, the third in Vande Hei's career and the first for Tingle. Vande Hei will venture outside the station again Jan. 29 with Flight Engineer Norishige Kanai of the Japan Aerospace Exploration Agency (JAXA) to stow a spare latching end effector removed from the robotic arm last October on to the station's mobile base system rail car for future use.

Spacewalkers have now spent a total of 53 days, 13 hours, and 49 minutes working outside the station in support of assembly and maintenance of the orbiting laboratory.

On-Orbit Status Report

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.
