Spacewalk to wrap up second solar array installation at space station

French astronaut Thomas Pesquet and NASA crewmate Shane Kimbrough prepped for a third spacewalk outside the International Space Station on Friday to install the second of six roll-out solar arrays. It's part of a major upgrade to offset age-related degradation in the lab's existing solar wings.

As with all NASA spacewalks, the excursion is expected to begin when Pesquet and Kimbrough, floating in the station's Quest airlock, switch their spacesuits to battery power around 8 a.m. EDT. It will be Kimbrough's ninth spacewalk, Pesquet's fifth and the 241st in the 23-year history of the space station. For identification, Pesquet, call sign EV-1, will be wearing a suit with red stripes while Kimbrough, EV-2, will be wearing an unmarked suit. Both men will be equipped with high-definition helmet cameras.
