NASA Investigates Issues with International Space Station's Canadarm2 Robotic Arm

Canadarm2 Mobile Transporter Experiences Errors

The International Space Station's Canadarm2 robotic arm, a 58-foot-long component supplied by the Canadian Space Agency, encountered operational issues with its mobile transporter. These problems arose after a routine 'walk-off' maneuver, which allows the arm to reposition itself along the station's exterior. The arm itself is currently functioning for inspections, but the non-robotic components of the mobile transporter are exhibiting communication errors.

Investigation Underway

NASA engineers are actively working to determine the root cause of these communication errors. The investigation focuses on whether the problem stems from data or software issues, or if it is related to the hardware of the robotic arm or the mobile transporter. The current position of the transporter, at Worksite 6, prevents its movement.

Potential Impact on Dragon Spacecraft

In parallel with the transporter investigation, NASA and SpaceX teams are assessing whether the mobile transporter's current position is causing GPS interference that could affect the Crew-12 Dragon spacecraft's docking capability. This analysis is crucial for predeparture procedures and the upcoming Crew-13 launch. Joint teams expect to resolve the issue before the Crew-13 launch.

Aging Hardware

The Canadarm2, developed by MDA, was launched in April 2001 and has a nominal design lifetime of 15 years. It has been operating for over a decade beyond its original design life, serving as a critical component of the International Space Station.
