The Canadarm2, the large robotic arm aboard the International Space Station, has reportedly stopped working, according to Ars Technica. The arm is essential for capturing cargo spacecraft, moving equipment and supporting spacewalks, so its failure could complicate station operations and resupply missions. Details on the cause and repair prospects remain limited, and space watchers are discussing what the breakdown means for the aging station.

Why now: A failure of the ISS's critical robotic arm would affect station operations and resupply, drawing attention from the space community.
