Indian-origin Nasa astronaut upgrades space station in major spacewalk

Indian-origin astronaut Anil Menon and Canadian astronaut Joshua Kutryk successfully completed a nearly seven-hour spacewalk on November 5, 2026 (US time), to install the eighth and final International Space Station Roll-Out Solar Array (IROSA). This achievement marks a significant milestone in a five-year initiative to boost the ISS's electricity-generating capacity from 160 kilowatts to approximately 215 kilowatts, which will support ongoing scientific experiments and onboard systems.

Context

The International Space Station has been a hub for scientific research since its launch, relying on solar power for its operations. The addition of the Roll-Out Solar Arrays is part of a long-term plan to increase the station's energy capacity. Anil Menon, an Indian-origin astronaut, exemplifies the growing diversity in space missions.

Why it matters

The successful installation of the final solar array is crucial for enhancing the International Space Station's power supply. This upgrade will enable more extensive scientific research and improve the station's operational capabilities. It highlights the contributions of astronauts from diverse backgrounds to international space exploration.

Implications

The upgrade is expected to facilitate more ambitious scientific experiments, potentially leading to new discoveries. Increased power capacity may also extend the operational life of the ISS. This development could influence future collaborations among space agencies and private companies in space exploration.

What to watch

Future missions may focus on how the increased power capacity impacts ongoing research projects aboard the ISS. NASA and its international partners will likely monitor the performance of the new solar arrays. Upcoming spacewalks and missions may also involve further enhancements to the station.
