NASA astronauts Anne McClain and Nichole Ayers will install a mounting bracket to prepare for the future installation of an additional set of International Space Station Rollout Solar Arrays, also called IROSA. The IROSAs will increase power generation capability by up to 30%, increasing the station’s total available power from 160 kilowatts to up to 215 kilowatts. The astronauts also will relocate a space station communications antenna.  

McClain will serve as spacewalk crew member 1 and will wear a suit with red stripes. Ayers will serve as spacewalk crew member 2 and will wear an unmarked suit. This will be the third spacewalk for McClain and the first for Ayers. U.S. spacewalk 93 will be the 275th spacewalk in support of space station assembly, maintenance, and upgrades.
