NASA astronauts Jessica Meir and Anil Menon conducted a spacewalk outside the International Space Station on Aug. 6 [4].
The mission is critical for maintaining the station's energy infrastructure as it enters its final years of operation. By modifying the power systems now, NASA ensures the orbital laboratory can support advanced research and maintain stability.
Exiting through the Quest airlock, the duo worked to install hardware designed to modify the station's 3B power channel [1]. This modification is a prerequisite for the future installation of an International Space Station Roll-Out Solar Array, known as IROSA [1].
The extravehicular activity was planned for a duration of seven hours [3]. For Anil Menon, the mission marked his first spacewalk [2]. For Jessica Meir, the outing was her sixth overall [1], and her third spacewalk of 2026 [5].
The installation of the IROSA hardware allows the station to increase its power-generation capacity. This upgrade is necessary to offset the degradation of older solar arrays and to provide the electrical load required by new scientific experiments.
NASA coordinated the EVA to ensure the 3B power channel was correctly configured before the new arrays are delivered. The successful modification of this channel prevents potential power failures and optimizes the distribution of energy across the station's modules [1].
“Anil Menon conducted his first spacewalk during the seven-hour mission.”
This mission represents a transition phase for the International Space Station. By installing the IROSA-compatible hardware, NASA is extending the operational viability of the station's power grid. This ensures that the facility remains a functional research hub while the agency prepares for the eventual transition to commercial space stations.
