NASA’s October 29 coverage followed two astronauts as they suited up for a lengthy excursion outside the International Space Station. The spacewalk was scheduled to start at about 8 a.m. EDT and was expected to run for more than six and a half hours.

NASA Blogs reported the preparations on Thursday, October 29. Because that timetable had passed by October 30, the announcement is best understood as the agency’s operational plan rather than confirmation that every task was completed as intended.

NASA astronaut Anil Menon and Canadian Space Agency astronaut Joshua Kutryk were assigned to leave the orbiting laboratory through the Quest airlock. Quest serves as the transition point between the station’s pressurized interior and the vacuum where crews conduct external maintenance and assembly work.

Their principal objective was to install and deploy an International Space Station Roll-Out Solar Array, widely identified by the acronym IROSA. The new array was designated for the 2A electrical power channel, placing the excursion within the continuing effort to reinforce the station’s power-producing infrastructure.

The hardware was to become the seventh IROSA installed on the ISS. Roll-out arrays can be transported in a compact configuration before being extended outside the station, an approach suited to upgrading a large orbital complex whose exterior already carries extensive structures and equipment.

NASA said the additional power would support critical station operations. The agency specifically included the ISS’s eventual safe and controlled deorbit among those needs, giving the assignment significance beyond routine power consumption during scientific and crew activities.

That connection highlights the long planning horizon behind station maintenance. An upgrade performed during the operational life of the laboratory may also contribute to the systems required as the program approaches later phases, when reliable power will remain essential for managing the spacecraft in a controlled manner.

Menon was designated extravehicular crew member 1 and was to wear a spacesuit marked with red stripes. Kutryk, assigned as crew member 2, was to use an unmarked suit. The contrasting markings allow flight controllers and viewers of the live feed to identify each astronaut when helmets and otherwise similar suits obscure individual features.

The assignment brought together markedly different spacewalking experience. It was scheduled to be Menon’s fourth excursion beyond the station and Kutryk’s first, pairing an astronaut with prior extravehicular work with a colleague making his debut outside the spacecraft.

NASA described the operation as U.S. spacewalk 100. It was also listed as the 285th spacewalk devoted to ISS assembly, maintenance and upgrades, a broader total that places the planned work within decades of construction and servicing around the multinational outpost.

A duration exceeding six and a half hours underscored the scale of the activity. Such an excursion encompasses more than the visible deployment of a solar array: astronauts must pass through airlock procedures, reach the worksite, handle hardware while restrained in microgravity and return safely to the station’s interior.

The agency provided live coverage through NASA’s online broadcast service and directed audiences to the space station blog and official social-media channels for continuing updates. The original notice, however, documented the schedule, crew assignments and intended objective; it did not provide a post-spacewalk account establishing how the deployment ultimately proceeded.
