NASA, for the time being, is unable to move the space station's large robotic arm

Astronauts on the International Space Station performed a routine walk-off maneuver with Canadarm2, the 58-foot robotic arm supplied by the Canadian Space Agency. After the maneuver, both the arm and its mobile transporter became immobile, preventing further movement along the station’s main truss. The issue renders the arm unusable for the time being.
