The Canadarm2 is a critical component of the ISS, used for various tasks such as docking spacecraft and handling cargo. A malfunction in its wrist joint could hinder these operations, potentially delaying missions and increasing operational risks. The successful repair will ensure the robotic arm remains fully functional, supporting ongoing and future ISS activities. Astronauts conducting the spacewalk face inherent risks, including exposure to the vacuum of space and potential equipment malfunctions.
