The ISS has deployed its seventh new solar array. One remains
The completed spacewalk adds power on channel 2A; the final roll-out array is planned for November 5.
Astronauts have installed and deployed the International Space Station’s seventh roll-out solar array, bringing its power upgrade one step closer to completion. The October 29 spacewalk added the array to electrical channel 2A; an eighth and final unit is planned for a November 5 excursion.
NASA’s completed-spacewalk report is careful about the sequence. The seventh array is installed. The full eight-array upgrade, and the combined capacity associated with it, are not yet complete.
Extra generation has more than one job
NASA astronaut Anil Menon and Canadian Space Agency astronaut Joshua Kutryk spent seven hours and 11 minutes outside the station. They installed the roll-out array and completed preparation tasks for the next spacewalk, when the final array is intended for channel 3B.
The agency says the complete set will raise available power from about 160 kilowatts to approximately 215 kilowatts, describing the increase as up to 30%. Those are system-level planning figures, not a claim that the seventh array alone adds 55 kilowatts or that generation remains at one fixed value throughout every orbit.
NASA explicitly includes support for a safe, controlled deorbit among the reasons for the extra electrical capacity. That connects routine maintenance with the station’s end-of-life planning. An aging orbital platform still needs reliable power while it operates and while the systems responsible for its final phase are prepared.
Completion is a separate event
The next spacewalk remains a planned operation. Its outcome should not be assumed simply because preparation work has been completed. NASA says coverage is scheduled to begin at 06:45 Eastern time on November 5, with viewing information on its live page.
The photograph shows Menon working from Canadarm2 during the installation, rather than a rendering of the finished eight-array configuration. That distinction helps keep the visible work connected to the milestone actually achieved.
The station’s longevity depends on these unglamorous increments: an electrical channel, a deployed panel and preparation for the next task. Seven arrays are now in place. The final installation will turn a sequence of individual spacewalks into the completed power upgrade.
