Our main task will be to complete the install of an “IROSA mod kit,” which will serve as the mounting plate to attach an @iss Roll-Out Solar Array (IROSA). This new, compact, roll-out solar array will augment the aging ISS arrays by providing a significant boost to the existing power system. Here we are practicing building the mod kit inside the LAB… Always useful since we will lose a lot of our dexterity once we are in the pressurized volume of our spacesuits!".
