ISS Spacewalk Scheduled for August 2026

European Space Agency astronaut Sophie Adenot is preparing to venture outside the International Space Station on Tuesday, August 25, 2026, for a scheduled spacewalk in low Earth orbit, according to mission announcements and updates from the European Space Agency and the International Space Station program.

The extravehicular activity requires astronauts to spend hours working in the harsh vacuum of space, performing critical maintenance, equipment upgrades, or scientific hardware installations outside the orbiting laboratory. Spacewalks demand rigorous preparation, precise coordination with flight controllers on the ground, and extensive safety checks of the spacesuits that protect crew members from extreme temperatures and solar radiation.

Preparation protocols for the spacewalk involve reviewing step-by-step procedures, checking life support systems, and depressurizing the airlock before the hatch opens into the void of space. Mission controllers at ground stations across the globe monitor every phase of the operation to ensure the safety and success of the crew members working outside the pressurized module.

Further details regarding the specific tasks assigned to Adenot during the excursion and the expected timeline of the operations continue to be tracked through official mission channels and updates from space agencies participating in the International Space Station partnership.
