Summary form only given, as follows. NASA's Mars 2020 Perseverance rover takes a "rover selfie," albeit with a twist. For the first time, in this image taken 6 April 2021, a rover captured not only itself but a buddy— the tiny helicopter Ingenuity, which made the trip in Perseverance’s belly. What looks like a single wide-angle shot is actually 62 individual images stitched together, according to Vandi Verma, the mission’s chief engineer for robotic operations. The pictures were taken with the rover’s WATSON (for Wide Angle Topographic Sensor for Operations and eNgineering) camera, situated at the end of the rover’s robotic arm. The arm ultimately doesn't appear because the stitched-together images overlap in those areas, giving the impression of a floating camera. When not being used for selfies, WATSON takes highly detailed photographs of the Martian surface to identify possible spots of interest for Perseverance's scientific instruments.

红色星球自拍【大图】

仅给出汇总表，如下。美国宇航局的火星 2020 Perseverance 漫游车进行了“漫游者自拍”，尽管有些扭曲。在 2021 年 4 月 6 日拍摄的这张照片中，火星车第一次不仅捕捉到了自己，还捕捉到了一个伙伴——小型直升机 Ingenuity，它在毅力号的肚子里旅行。根据该任务机器人操作总工程师万迪维尔马的说法，看起来像一个广角镜头实际上是拼接在一起的 62 张独立图像。这些照片是用漫游车的 WATSON（用于操作和工程的广角地形传感器）相机拍摄的，位于漫游车机械臂的末端。手臂最终不会出现，因为拼接在一起的图像在这些区域重叠，给人一种浮动相机的印象。不用来自拍的时候，
