Watch Second Expedition 42 Spacewalk on NASA TV

NASA Television will provide live coverage of today’s U.S. spacewalk conducted from the International Space Station beginning at 6 a.m. EST. The spacewalk is scheduled to begin at 7:10 a.m. and run about 6-1/2 hours.

Expedition 42 Commander Barry Wilmore and Flight Engineer Terry Virts will venture outside the orbital complex for the second of three spacewalks to prepare cables for new docking ports that will allow future crews launching from Florida on U.S. commercial spacecraft to dock to the space station. They also will make other preparations for a reconfiguration of the space station in advance of the arrival of private crewed spacecraft.

Wilmore is wearing a spacesuit with red stripes and is designated EV1. His helmet camera displays the number 18. Virts is wearing a spacesuit with no stripes and is designated EV2. His helmet camera displays the number 20.

During a spacewalk on Saturday, Feb. 21, the duo spent 6 hours, 41 minutes outside deploying eight bundles of cables. Tomorrow they will route two additional bundles, lubricate parts of the Latching End Effector of the space station’s robotic arm and prepare the Tranquility module for the relocation later this year of the Permanent Multipurpose Module and the arrival of the Bigelow Expandable Activity Module, an expandable space habitat technology.
