Introduction
Marking a triumphant personal and scientific milestone in orbital human spaceflight, Indian-origin NASA astronaut Dr. Anil Menon successfully completed his first career spacewalk (Extravehicular Activity - EVA) outside the International Space Station (ISS) on 17 August 2026 alongside veteran NASA astronaut Jessica Meir, spending 6 hours and 27 minutes in the vacuum of outer space during US Spacewalk 96.
Mission Objectives and Orbital Infrastructure Upgrades
The spacewalk executed critical infrastructure upgrades to extend the operational lifespan of the ISS:
- 3B Power Channel Preparation: Prepared the orbital laboratory's Truss 3B electrical power channel for the subsequent installation of new IROSA (International Space Station Roll-Out Solar Arrays).
- Power Generation Boost: The IROSA arrays will generate an additional 120 kilowatts of electricity, restoring power capacity to the ageing space station and ensuring stabilized power systems until its planned controlled de-orbit in 2030–31.
- Rigorous EVA Physics: Conducted maintenance in extreme temperatures ranging from -120°C to +120°C while tethered 400 kilometres above Earth, relying entirely on the Extravehicular Mobility Unit (EMU) spacesuit for life support.
