Astronauts Repair Robotic Arm on International Space Station During Spacewalk

Two astronauts successfully conducted a spacewalk outside the International Space Station (ISS) to repair a critical robotic arm. NASA astronaut Jessica Meir and her colleague Chris Williams spent approximately seven hours outside the station, replacing a heavy, 90-kilogram joint on the arm.

The robotic arms are essential components of the ISS, utilized for various tasks, including the docking of spacecraft. The successful replacement of the joint ensures the continued functionality of this vital equipment.

This mission marked a significant milestone for both astronauts. It was the second spacewalk for Williams and the fifth for Meir, contributing to the extensive history of extravehicular activities conducted on the ISS. In total, this was the 280th spacewalk in the station's operational history.

The repair operation underscores the ongoing maintenance and operational efforts required to sustain the ISS as a platform for scientific research and international cooperation in space.
