iss073e0133686 (June 3, 2025) --- JAXA (Japan Aerospace Exploration Agency) astronaut and Expedition 73 Commander is pictured during maintenance operations on the Japanese robotic arm's Small Fine Arm inside the Kibo laboratory module. The Small Fine Arm is used for precise and dexterous robotic maneuvers when grappling small components or payloads on the outside of the International Space Station. There are two other robotic arms on the outside of the orbital outpost including the Canadarm2 robotic arm and the European robotic arm (ERA). Canadarm2 can be used to maneuver spacecraft, spacewalkers, and large payloads. ERA can also be used to maneuver spacewalkers and space station components.
