Two NASA astronauts will venture outside the International Space Station, conducting US spacewalk 93 on May 1, 2025, to complete station upgrades.
NASA astronauts Anne McClain and Nichole Ayers will relocate a space station communications antennae and install a mounting bracket ahead of the installation of an additional set of International Space Station Rollout Solar Arrays, also called IROSA.
The arrays will boost power generation capability by up to 30%, increasing the station’s total available power from 160 kilowatts to up to 215 kilowatts. The arrays will be installed on a future spacewalk following their arrival on a SpaceX Dragon commercial resupply services mission later this year.
McClain will serve as spacewalk crew member one and will wear a suit with red stripes. Ayers will serve as spacewalk crew member two and will wear an unmarked suit. This will be the third spacewalk for McClain and the first for Ayers. US spacewalk 93 will be the 275th spacewalk in support of space station assembly, maintenance, and upgrades.
The spacewalk is scheduled to last about six and a half hours. NASA will provide additional information, including live NASA+ coverage details, when available.
