NASA astronaut Shane Kimbrough and ESA astronaut Thomas Pesquet maneuver the first ISS Roll-Out Solar Array (iROSA) into place on the space station’s port 6 truss structure during a spacewalk on 16 June.
Two astronauts will venture outside the International Space Station on 25 June for a third spacewalk to continue power system upgrades that are already increasing output and proving the technology that will enable NASA’s future Gateway lunar outpost.
The crew members are scheduled to exit the station’s Quest airlock around 8am, and the spacewalk will last approximately six hours and 30 minutes.
Shane Kimbrough of NASA and Thomas Pesquet of ESA (European Space Agency) will install and deploy the second of six new ISS Roll-Out Solar Arrays (iROSA) on the station’s 4B power channel.
Pesquet will be extravehicular crew member 1 (EV 1), with red stripes on his spacesuit, while Kimbrough will be extravehicular crew member 2 (EV 2), with an unmarked suit.
During the spacewalk, Pesquet will secure himself to the end of the station’s robotic Canadarm2 then grasp the iROSA.
Operating from inside the station, NASA astronaut Megan McArthur, with NASA astronaut Mark Vande Hei serving as backup, will command the robotic arm to manoeuvre Pesquet and the array as close as possible to the installation location.
