Second spacewalk – replay
UPDATED with replay
ESA astronaut Thomas Pesquet and NASA astronaut Shane Kimbrough will venture outside the International Space Station to install a new computer and disconnect a docking adapter to allow its move to a new location.
They will spend most of the spacewalk working separately, with Thomas inspecting the Station’s radiator and maintaining the Dextre multipurpose robotic hand.
Shane will be wearing a spacesuit with red stripes, while Thomas will wear a spacesuit without stripes. Shane helmet camera view will have number 18 with Thomas' helmet camera number 20.

Details about the spacewalk are available in this blog entry. A rough schedule for the day is below, times in GMT:
|12:00||Hatch open||Hatch open|
|12:30||Install computer||Inspect radiator|
|14:00||Disconnect mating adapter||Maintain robotic hand|
|15:00||Replace camera light|
|17:00||Extra tasks if time allows||Extra tasks if time allows|
|17:30||Clean up and return to airlock||Clean up and return to airlock|
|18:00||Spacewalk ends||Spacewalk ends|
An acronym cheat-sheet for terms you might hear while following the spacewalk:
|EVA||Extra Vehicular Activity or spacewalk|
|Quest||The airlock Thomas and Shane will use to exit and return to the Space Station|
|P1 truss||A part of the Space Station where Thomas will inspect the cooling system|
|S0 truss||A part of the Space Station where Shane will install a new computer and Thomas will work on the robotic arm.|
|VE||Japanese camera units that Shane will retrieve|
|EPIC MDM||The computer Shane will replace (Enhanced Processor & Integrated Communications Multiplexer/Demultiplexer)|
|Node-3||A module on the Space Station that currently has the docking adapter Shane will uncouple, also called Tranquility|
|MLI||Multiple Layer Insulation that protects the cooling system Thomas will work on|
|SPDM||Special Purpose Dexterous Manipulator, the robotic arm Thomas will work on|
|LEE||Latching End Effector, the tip of the robotic arm that needs lubricating|
|PMA-3||Pressurized Mating Adapter-3 the docking adapter Shane will uncouple so it can be moved|
|R&R||Replace and Repair – replacing a unit with a new one|
|RBVM||Radiator Beam Valve Module, the cooling system Thomas will inspect for leaks|
|BLT||Ballscrew Lubrication Tool, that Thomas will use to grease the robotic arm|
|APFR||Articulating Portable Foot Restraint, a platform Thomas will stand on during the spacewalk to work with his hands free|
|Bootie||A protective cover over connections, Thomas removed these on the cooling system to inspect underneath|
