iss075e0014476 (Aug. 12, 2026) --- The Canadarm2 robotic arm’s latching end effector grapples visiting spacecraft, such as Northrop Grumman’s Cygnus XL cargo vehicle, to capture or release them from the International Space Station. It also attaches to power and data grapple fixtures on the orbital outpost for stability and maneuvers astronauts during spacewalks. Credit: NASA
