ISS Antenna Replacement Completed

On Tuesday, August 25, NASA astronaut Anil Menon and ESA astronaut Sophie Adenot carried out a spacewalk lasting approximately six hours and thirty minutes.

During the EVA they removed the existing Space‑to‑Ground antenna and installed a replacement unit on the exterior of the International Space Station.

The new antenna is intended to improve the station’s communications links with ground facilities, enhancing the downlink of scientific data and video feeds.

Both crew members had previously undergone extensive training in neutral‑buoyancy pools and virtual‑reality simulators to master the intricate tasks required in microgravity.

The spacewalk proceeded without any incidents, and ground controllers verified the operational status of the newly installed antenna after the astronauts re‑entered the station.

This activity forms part of the routine maintenance schedule designed to preserve the long‑term reliability of the ISS communication infrastructure.

  • Higher bandwidth for science payload data
  • More stable live‑video connections to mission control
  • Lower probability of comms loss during docking or debris‑avoidance maneuvers
