The critical robot arm on the ISS isn’t working properly, but NASA has a plan to fix it

AI-summarised brief · reviewed before publication

The Canadarm2 robotic arm on the International Space Station (ISS) has stopped working due to a faulty wrist joint, which will require a spacewalk to repair. The arm, crucial for catching cargo ships and maintenance duties, has been offline since May 27. A spare joint is already on the station, and NASA plans a spacewalk for June 30. The repair is critical to berth cargo ships and perform maintenance on the ISS. The arm was designed with replaceable segments, and a similar repair was done in 2017.

💡 Why It Matters

  • · The successful repair of Canadarm2 will ensure the continued operation of the ISS, which relies on the arm for cargo berthing and maintenance.
  • · The arm's failure could have significant consequences for the station's operations, including delays in receiving essential supplies and equipment.
