Indian-origin NASA Astronaut Anil Menon Completes Maiden ISS Spacewalk
On 6 August 2026, Indian-origin NASA astronaut Anil Menon performed his first extravehicular activity (EVA), commonly known as a spacewalk, outside the International Space Station (ISS). Alongside NASA astronaut Jessica Meir, Menon conducted a 6-hour 27-minute spacewalk designated US Spacewalk 96, targeting upgrades to the ISS power system.

Key Facts
- Date and Time: The spacewalk occurred on 6 August 2026, lasting approximately 6 hours and 27 minutes, concluding at about 3 p.m. EDT (12:30 a.m. IST on 7 August 2026).
- Participants: Anil Menon (making his maiden spacewalk) and Jessica Meir (executing her sixth spacewalk).
- Purpose: Installation of mounting hardware on the ISS's Starboard 6 truss segment 3B power channel, routing electrical cabling for future installation of a Roll-Out Solar Array (iROSA), and wrapping struts with multi-layer insulation to protect against extreme space conditions.
- Significance: This was the 281st spacewalk dedicated to ISS assembly and maintenance, and the first of three planned EVAs scheduled for the Expedition 75 crew in August 2026.
- Anil Menon's Background: Selected to NASA’s 2021 astronaut class; former SpaceX medical director and emergency medicine physician; born in Minneapolis to an Indian father from Kerala and a Ukrainian mother.
Background & Context
Extravehicular activities (EVAs), or spacewalks, are essential for maintaining, repairing, and upgrading orbital infrastructure such as the ISS. The ISS relies on solar arrays for power; however, the original arrays experience degradation over time due to prolonged exposure to space radiation and thermal cycling. The Roll-Out Solar Arrays (iROSAs) are newer deployable solar panels designed to augment the ISS’s electrical generation capacity, ensuring continued power supply for scientific research, station operations, and supporting its eventual safe deorbit.
The installation of mounting hardware and electrical connections performed during this EVA are preparatory steps for iROSA installations planned for later in 2026, marking a critical incremental upgrade to extend the ISS's operational viability.
Why This Matters for Exams / Exam Relevance
- Showcases the ongoing international efforts in space station maintenance and upgrades, emphasizing scientific and technological collaboration.
- Highlights contributions of Indian-origin scientists and engineers in prominent global space missions.
- Relevant for understanding terms like EVA, ISS modules (Starboard 6 truss), space station power systems, and the significance of solar arrays.
- Memorizing dates, astronaut names, and mission details can help in objective-type and general awareness exams.
Points to Remember
- Anil Menon's first spacewalk occurred on 6 August 2026, lasting 6 hours 27 minutes, outside the ISS.
- Main activities involved preparing the 3B power channel on the Starboard 6 truss for future iROSA solar array installation.
- The EVA was part of Expedition 75's planned spacewalks to maintain and upgrade ISS systems.
- This was U.S. Spacewalk 96 and the 281st spacewalk in support of the ISS.
- Anil Menon is a NASA astronaut with medical and engineering credentials, contributing significantly to human spaceflight programs.
