NASA astronaut Anil Menon and Canadian Space Agency astronaut Joshua Kutryk are preparing for a spacewalk outside the International Space Station, NASA said in a blog post. The excursion, designated U.S. spacewalk 101, is scheduled to begin at approximately 8:30 a.m. EST and last more than six and a half hours, with live coverage streaming online.

During the spacewalk, the two astronauts will exit the station's Quest airlock to install and deploy the eighth and final IROSA on the 3B channel, which NASA describes as completing the station's power augmentation upgrades. The agency says the solar array will provide additional power for critical station operations, including its safe and controlled deorbit.

Kutryk will serve as spacewalk crew member 1 in a suit with red stripes, while Menon will be crew member 2 in an unmarked suit. NASA says the spacewalk will be Menon's fifth and Kutryk's second, and marks the 286th spacewalk supporting station assembly, maintenance and upgrades.
