NASA Astronauts Step Into Open Space To Repair Critical ISS Robotic Arm Mid-Mission

A rare and technically demanding spacewalk is underway outside the International Space Station, where NASA astronauts Chris Williams and Jessica Meir are working to restore full functionality to the station’s Canadarm2 robotic system following a critical malfunction reported in late May, according to NASA. The operation highlights both the fragility and resilience of orbital infrastructure that has supported continuous human presence in space for more than two decades, as crews perform intricate mechanical work in vacuum conditions while moving at orbital velocity.
