NASAs Curiosity rover accidentally pulled a rock out of Mars

NASAs Curiosity rover had an unexpectedly stubborn Mars souvenir after drilling into a rock nicknamed Atacama - the entire chunk ripped loose from the ground and stayed stuck to the rovers drill. Engineers watched as Curiosity shook, vibrated, tilted, and spun the drill over several days in an effort to free the rock, while cameras captured the strange scene on the Red Planet.
