Astronauts Begin Spacewalk to Upgrade Station PowerNASA astronaut Steve Bowen and UAE (United Arab Emirates) astronaut Sultan Alneyadi began a spacewalk at 9:11 a.m. EDT to prepare for future installation of upgraded solar arrays on the starboard side of the stationís truss. The astronauts will then retrieve S-band antenna equipment and bring it inside the space station for refurbishment.The spacewalk is part of a series to augment the stationís power channels with new International Space Station Roll-Out Solar Arrays (iROSAs). Four of the new arrays have been installed so far, and two additional arrays will be mounted to the installed platforms during future spacewalks following their arrival this year on SpaceXís 28th commercial resupply services mission for NASA.Bowen serves as extravehicular crew member 1 (EV 1) and is wearing a suit with red stripes. Alneyadi serves as extravehicular crew member 2 (EV 2) and is wearing an unmarked suit. U.S. spacewalk 86 is the eighth spacewalk for Bowen and the first for any UAE astronaut.Coverage of the spacewalk continues on NASA Television, the NASA app, and the agencyís website.Learn more about station activities by following the space station blog, @space_station and @ISS_Research on Twitter, as well as the ISS Facebook and ISS Instagram accounts.Get weekly video highlights at: https://roundupreads.jsc.nasa.gov/videupdate/Get the latest from NASA delivered every week.
