NASA astronaut Anil Menon and Canadian Space Agency astronaut Joshua Kutryk were scheduled Thursday to install the eighth and final roll-out solar array on the International Space Station, according to Space.com¹.

The roughly seven-hour outing, U.S. spacewalk 101, was set to begin at 8:30 a.m. EST, Space.com reported, with NASA video coverage starting about 7 a.m. Eastern¹. Reuters carried a livestream of astronauts working outside the station².

The pair installed the station's seventh International Space Station Roll-Out Solar Array, or iROSA, on Oct. 29, Space.com said, describing that excursion as the 100th U.S. spacewalk from the ISS¹.

NASA officials wrote that finishing the installation would complete a process begun in June 2021 to raise the station's power generating capacity from 160 kilowatts to about 215 kilowatts, about a 30% increase, Space.com reported¹.

Menon and Kutryk were sharing the station with NASA astronauts Luke Delaney and Jessica Watkins and Roscosmos cosmonauts Pyotr Dubrov, Anna Kikina and Sergey Teteryatnikov, according to Space.com¹. Delaney, Kutryk, Teteryatnikov and Watkins arrived Oct. 1 on SpaceX's Crew-13 mission; Dubrov, Kikina and Menon arrived in mid-July on a Soyuz, the outlet said¹.

Whether the spacewalk started on time, finished the array, or ran into delays was not detailed in Space.com's preview or in the Reuters stream listing^1,2.
