NASA Astronauts to Replace Canadarm2 Joint in 6.5-Hour ISS Spacewalk 95

Summary
Tuesday’s ISS spacewalk will send Chris Williams and Jessica Meir outside at 8:35 a.m. EDT to swap out a malfunctioning wrist joint on the Canadarm2 robotic arm.
The joint failed during normal operations on May 27, when the arm drew elevated motor current and did not move as expected, prompting NASA and the Canadian Space Agency to conclude an EVA was required.
NASA said the repair will use a spare part already aboard the station; the agency expects the outing to last about six-and-a-half hours and will begin live coverage at 7 a.m. EDT.
The mission will be Williams’ second spacewalk, Meir’s fifth, and the 280th spacewalk supporting ISS assembly, maintenance and upgrades.
NASA framed the fix as routine long-term upkeep for Canadarm2, whose replaceable components were designed for planned maintenance after more than 25 years of continuous operations.
