Why the ISS’s August 18 Spacewalk Depends on Robotics as Much as Spacewalking

NASA says Anil Menon and Sophie Adenot are preparing for an approximately six-and-a-half-hour spacewalk to replace a high-speed data and communications antenna, with Canadarm2 and the crew inside the station supporting the work.

What NASA is planning

NASA’s August 14 station update says Anil Menon and Sophie Adenot are preparing to remove an old high-speed data and communications antenna from the Z1 truss and replace it with a spare. The planned sequence includes temporarily stowing the old unit, retrieving the spare from an external platform, making electrical and data connections, and moving the old antenna back to the platform.

Why robotics is part of the spacewalk

The operation is not only an EVA task. NASA says station commander Jessica Meir and flight engineer Jack Hathaway will support the crew from inside the station and operate Canadarm2. Menon is expected to be attached to the robotic arm for parts of the work so he can reach maintenance locations. The crew has been rehearsing arm movements, operating modes and safety procedures before the spacewalk.

Why the antenna matters

NASA describes the hardware as a high-speed data and communications antenna. Replacing aging communications hardware is the kind of infrastructure maintenance that keeps the station useful as an orbital laboratory; the immediate goal is reliability rather than a new scientific capability.

Current status

Expedition 75 is an active mission. NASA’s current mission page says the expedition began July 26, 2026 and includes Meir, Menon, Hathaway and Adenot among its seven crew members. The August 18 activity should still be treated as planned until NASA confirms the spacewalk has started or completed.

What to watch next

The next material update is whether NASA keeps the August 18 schedule, how long the spacewalk lasts, whether the spare antenna is installed successfully, and whether any changes are made to the planned Canadarm2 sequence. Atalk.TV will update this durable URL rather than create a duplicate story for routine countdown changes.
