ESA (European Space Agency) astronaut Thomas Pesquet and NASA astronaut Shane Kimbrough have begun their spacewalk outside the International Space Station to install and deploy the second of two new ISS Roll-Out Solar Arrays (iROSA).

The spacewalkers switched their spacesuits to battery power at 7:52 a.m. EDT to begin the spacewalk, which is expected to last about six and a half hours.

Watch the spacewalk on NASA TV, the NASA app, and the agency’s website.

Pesquet is extravehicular crew member 1 (EV 1), wearing a spacesuit bearing red stripes and using helmet camera #20. Kimbrough is extravehicular crew member 2 (EV 2), wearing the unmarked spacesuit and helmet camera #22.

It is the fifth spacewalk Kimbrough and Pesquet have conducted together and the third during this mission to install new solar arrays. During Expedition 50, they conducted two spacewalks together in January and March 2017 that included another station power upgrade, replacing nickel-hydrogen batteries with new lithium-ion batteries.

From inside the space station, NASA astronaut Megan McArthur will command Canadarm2 with Pesquet attached to maneuver the array closer to the installation location on the far end of the left (port) side of the station’s backbone truss structure (P6) to upgrade the 4B power channel.

This is the 241st spacewalk in support of space station assembly.
