NASA U.S. Spacewalk 93

On Thursday, May 1, NASA astronauts Anne McClain and Nichole Ayers will step outside the International Space Station to complete station upgrades. The spacewalk is scheduled to begin at 8 a.m. EDT (1200 UTC) and last about six and a half hours.

McClain and Ayers will relocate communications antenna and install a mounting bracket to prepare for the installation of a new set of International Space Station Rollout Solar Arrays, also called IROSAs, on a later spacewalk. The arrays will boost the station's power generation capability by up to 30%.

McClain will wear a suit with red stripes; Ayers will wear an unmarked suit. This will be the third spacewalk for McClain and the first for Ayers.
