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 first new ISS Roll-Out Solar Array (iROSA).
The spacewalkers switched their spacesuits to battery power at 8:11 a.m. EDT to begin the spacewalk, which is expected to last about six and a half hours.
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 third spacewalk Kimbrough and Pesquet have conducted together, following two Expedition 50 spacewalks 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 2B power channel.
This is the 239th spacewalk in support of space station assembly.
