Astronauts Successfully Deploy New Solar Panels During Spacewalk

NASA's Anil Menon and CSA's Joshua Kutryk completed a seven-hour mission to enhance the International Space Station's power generation capabilities.

NASA astronaut Anil Menon and Canadian Space Agency astronaut Joshua Kutryk recently embarked on a spacewalk to install and deploy an International Space Station Roll-Out Solar Array (IROSA), a move aimed at boosting the station’s power output. According to reports, the duo spent 7 hours and 11 minutes outside the ISS, successfully unfurling the new solar array which is expected to generate approximately 8 kilowatts of electricity 23.

The installation of the IROSA marks a significant step in enhancing the power generation capabilities of the International Space Station. The original solar wings, installed between 2000 and 2009, were designed to last 15 years, but now face partial shading from the newer arrays 2. This upgrade is crucial for maintaining and potentially expanding the station’s operations and research activities.

The spacewalk was deemed essentially flawless by NASA Mission Control, highlighting the smooth execution of the task 2. It was also noted that this was Menon's fourth spacewalk, while for Kutryk, it marked his inaugural venture into the vacuum of space 3.

Looking ahead, the astronauts have another spacewalk scheduled for November 5, 2026, where they will install the final solar array, completing the series of upgrades to the station's power system 23.
