NASA astronauts Chris Williams and Jessica Meir will conduct a spacewalk on Tuesday, June 30, to replace a malfunctioning wrist joint on Canadarm2. The issue occurred on May 27, when the arm drew elevated motor current during routine operations and failed to move as expected.
NASA worked alongside CSA (Canadian Space Agency) to understand the issue and determined a spacewalk was required to replace the joint using a spare already aboard the space station. Repairs to robotics, like Canadarm2, are normal and expected after more than 25 years of continuous operations, as the system was designed with replaceable components and planned maintenance in mind.
Live coverage of the spacewalk begins at 7 a.m. EDT on NASA+, Amazon Prime, Netflix, and the agency’s YouTube channel.
