It meant the stuck rock, which has been nicknamed \u201cAtacama\u201d, took a week to sort out. <\/p>\n<p>\u201cWhen the rover retracted its arm, the entire rock lifted out of the ground, suspended by the fixed sleeve that surrounds the rotating drill bit,\u201d <a href=\"https:\/\/science.nasa.gov\/photojournal\/nasas-curiosity-rover-frees-its-drill-from-a-rock\/\" data-wpel-link=\"external\" target=\"_blank\" rel=\"follow external noopener nofollow\">NASA explains in a blog post<\/a>. <\/p>\n<p>\u201cDrilling has fractured or separated the upper layers of rocks in the past, but a rock has never remained attached to the drill sleeve.
