NASA's Canadarm2, the International Space Station's essential 58-foot robotic arm, has encountered operational difficulties following a routine maneuver performed by astronauts. Initially, engineers were uncertain whether the issue stemmed from software, data, or hardware problems. The malfunction matters significantly because the arm is critical for berthing cargo vehicles, moving heavy equipment during spacewalks, and performing essential maintenance tasks on the ageing space station. NASA and SpaceX are actively investigating and expect to resolve the issue before the upcoming Crew-13 launch.

According to NASA's statement, the Canadarm2 itself is currently operating as expected and is being used for spacecraft inspections. However, communication errors have appeared in non-robotic components of the mobile transporter—the carriage system that guides the arm along the station's main truss. The arm, supplied by the Canadian Space Agency and launched in 2001, was designed for a 15-year lifespan but has now been operating for over 25 years, far beyond its nominal lifetime. It can manipulate payloads up to 116 tonnes and is irreplaceable for berthing cargo vehicles, particularly as SpaceX plans to retire the Dragon spacecraft within four years. The incident underscores the International Space Station's ageing infrastructure, as the facility approaches its thirtieth anniversary whilst operating decades beyond its original specifications.
