8月22日，在第180号任务中，毅力号漫游车上的危险相机拍摄了这张清晰的照片，照片中可以看到火星耶泽罗陨石坑布满岩石的地面。直径52.5厘米（21英寸）的火星车的一个可操纵前轮位于画面的左下方。靠近中央的是一块昵称为罗切特的大岩石。然而，任务规划者并不想避开罗切特。相反，“毅力”号将被指示伸出其2米长的机械臂，磨损岩石表面，以确定它是否具有适合使用探测车的取心钻头获取比铅笔略厚的样本的稠度。毅力号收集的样本将在未来的火星任务中返回地球。

Taken on mission sol 180 (August 22) this sharp image from a Hazard Camera on the Perseverance rover looks out across a rock strewn floor of Jezero crater on Mars. At 52.5 centimeters (21 inches) in diameter, one of the rover's steerable front wheels is at lower left in the frame. Near center is a large rock nicknamed Rochette. Mission planners don't want to avoid Rochette though. Instead Perseverance will be instructed to reach out with its 2 meter long robotic arm and abrade the rock's surface, to determine whether it has a consistency suitable for obtaining a sample, slightly thicker than a pencil, using the rover's coring bit. Samples collected by Perseverance would be returned to Earth by a future Mars mission.
