Astronauts deploy solar array on 100th US spacewalk by International Space Station crew members
AI-summarised brief · reviewed before publication
Two astronauts, NASA’s Anil Menon and CSA’s Joshua Kutryk, completed the 100th U.S. spacewalk by installing and deploying the second‑to‑last International Space Station roll‑out solar array (iROSA). The 7‑hour EVA began and ended in the Quest airlock, with the crew unbolting the 750‑pound array from a Dragon cargo trunk, mounting it on the 2A electrical channel, and extending it to 63 feet using stored potential energy. The new panels boost the ISS power supply by 20‑30 % and support future operations, including the planned 2030 deorbit.
💡 Why It Matters
- · The upgraded solar arrays extend the station’s operational life and enable more complex missions, ensuring reliable power for critical systems as the ISS approaches its decommissioning phase.
