Canadarm2

The large robotic arm on the International Space Station has stopped working, and NASA says it cannot move it for the time being. Engineers are working to understand the fault on Canadarm2, which is essential for catching cargo spacecraft, moving astronauts during spacewalks and repositioning modules. The outage raises questions about station operations until the arm is restored.

The Canadarm2, the large robotic arm outside the International Space Station, has reportedly stopped working, according to an Ars Technica report. The arm is essential for capturing cargo spacecraft, moving equipment and supporting spacewalks, so a failure would be a significant operational problem for the station's crews and ongoing maintenance.

NASA says it is currently unable to move the International Space Station's large robotic arm, the Canadarm2, for the time being. The arm is essential for capturing cargo spacecraft, moving equipment and supporting spacewalks outside the orbiting laboratory. Few further details about the cause of the problem or expected repair timeline have been released, and observers are waiting for updates from the agency.

NASA says it is troubleshooting a transporter mechanism that moves the International Space Station's robotic arm along the station's truss. The issue affects the mobile base that allows the Canadarm2 to reposition itself for station maintenance and operations. NASA reports the station and its crew remain safe while engineers work the problem, though the arm's mobility may be limited until a fix is found.

The Canadarm2, the large robotic arm on the International Space Station, has reportedly stopped working. The arm is critical for capturing cargo spacecraft, moving equipment and supporting spacewalks, so a failure would be a significant operational problem for the station's crews and their backers at NASA and the Canadian Space Agency. Details on the cause and possible fixes remain limited.
