The International Space Station’s solar shrouds received a significant upgrade this week when NASA astronaut Anil Menon and Canadian Space Agency astronaut Joshua Kutryk launched into a daytime spacewalk at 7:57 a.m. Eastern Time on Thursday, October 29, 2026. The pair worked outside the station to install the seventh roll‑out solar array on the 2A electrical power channel, a move that should boost the space platform’s renewable energy supply and pave the way for its future safe deorbit.
According to Xinhua, the new array will be the seventeenth power‑generation unit to reach the ISS, but the latest installation is the station’s seventh roll‑out array, a modular design that can be deployed later if the need arises. The panel’s status as a “roll‑out” unit distinguishes it from earlier fixed solar arrays; it can be unfolded after being launched, allowing the ISS to replace aging panels without launching a new module.
NASA officials said the spacewalk was expected to last more than six and a half hours, a duration that matched the station’s long list of ongoing upgrades. The crew’s routine work is part of the 285th extravehicular activity that has supported the station’s assembly, maintenance and upgrades since 1998.
Menon’s fourth EVA and Kutryk’s first underscore a growing international partnership that keeps the ISS operational. The Canadian Space Agency, for its part, has contributed a substantial share of the research and materials for the roll‑out panels, illustrating the collaborative nature of contemporary space engineering.
The new solar array is designed to micro‑recharge the ISS’s batteries and supply additional power for instruments and experiments. NASA has highlighted that the panel will play a role in the station’s controlled deorbit, a mission that will eventually bring the spacecraft back to Earth in a safe, managed descent.
Expanding Solar Power for ISS
The 2A electrical power channel is a key site for solar power generation on the ISS. According to Xinhua, installing the new roll‑out array on this corridor will ease the strain on existing panels, improving reliability for critical systems. NASA’s blog notes that the initiative is a pre‑emptive measure to extend the station’s operational life beyond 2030, when the current solar arrays are expected to degrade.
Consultants and engineers who monitor the ISS’s energy budget report that the roll‑out array will add an estimated 70 watts to the station’s power supply. While the figure may seem modest in weight, it represents a critical redundancy layer for emergency operations and backup power during adverse weather on Earth's surface.
Long‑Term Sustainability in Microgravity
Deploying renewable energy solutions in the harsh environment of low‑Earth orbit also offers perspective for Earth-based sustainability efforts. By showcasing the viability of modular, easily deployable solar arrays in space, engineers can draw insights into lightweight and transportable solar technologies for remote areas on our planet.
At a time when terrestrial communities are turning to photovoltaic solutions to reduce fossil fuel dependence, the ISS’s roll‑out panels reinforce the message that clean energy is adaptable, whether in orbit or on the ground. The spacewalk itself demonstrates how human ingenuity can extend the usability of existing infrastructure, a concept that can feed back into redesigning aging power systems globally.
As the space program moves toward larger orbital habitats and lunar or Mars stations, the experience gained from installing and maintaining roll‑out solar panels on ISS will prove invaluable. The successful deployment marks a milestone in scaling renewable power systems beyond Earth’s atmosphere and underscores the broader trend toward sustainable, low‑impact energy generation in extreme environments.
In the coming months, NASA will evaluate the performance of the new array under varying sun angles, and data gathered will inform the design of next‑generation panels for deep‑space missions. The collaboration between NASA and the Canadian Space Agency exemplifies how shared expertise accelerates progress toward more sustainable and resilient space infrastructure.
