ISS Astronauts Complete Solar Array Upgrade with 7-Hour Spacewalk

Successful Seven-Hour Spacewalk

NASA astronaut Anil Menon and Canadian Space Agency (CSA) astronaut Joshua Kutryk conducted a 6-hour and 59-minute spacewalk outside the International Space Station (ISS). The duo successfully completed key assembly tasks on the station's exterior.

Final iROSA Array Installed

During the extravehicular activity, the astronauts installed and deployed the eighth and final International Space Station Roll-Out Solar Array (iROSA) onto the station's 3B power channel. This completed a major project designed to boost the orbital laboratory's overall power generation capability.

18 Spacewalks Since 2021

Efforts to upgrade the space station's power grid began in February 2021. Since then, astronauts have performed 18 spacewalks to prepare power channel equipment and mount the eight rollout solar arrays, successfully bringing the station's upgraded power capacity to 160 kilowatts.
