Canadarm2

The Canadarm2 robotic arm on the International Space Station has stopped working, according to a report by Ars Technica. The arm is critical for docking spacecraft, moving cargo and performing spacewalk support, so a failure would raise immediate operational concerns for NASA and its station partners. Details on the cause of the fault and the outlook for repairs were not given.

NASA is troubleshooting the transporter system that moves the International Space Station's robotic arm along the station's truss, according to Ars Technica. The issue affects the mobile base that allows the Canadarm2 to relocate and support operations outside the orbiting laboratory. Details on the nature of the fault and its impact on station operations remain limited.
