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.

Why now: The arm is critical to space station operations, and any malfunction raises urgent questions about resupply missions and repairs.
