NASA's Curiosity rover temporarily had a rock stuck to its robotic arm while working on Mars, spending about five to six days with the fragment attached before finally shaking it off. New reporting identifies the piece as roughly 29 pounds and confirms the episode followed a 25 April 2026 drilling attempt. The incident highlights how near-surface Martian rocks can behave unpredictably during sample collection and will inform how scientists interpret rock properties and plan future sampling, while concurrent operations like Psyche's May 15 gravity-assist flyby show the range of technical challenges across surface and flyby missions.
