第46个月（2021年4月6日），毅力号火星车伸出机械臂，在火星上拍了第一张自拍照。安装在机械臂末端的沃森（WATSON）相机被设计用来拍摄火星岩石和表面细节的特写，而不是朋友和笑脸的快速快照。最后，团队合作和数周的火星时间计划需要编程一系列复杂的曝光和相机运动，包括毅力号和它的周围环境。由此产生的62张照片组成了一张细致的马赛克，这是有史以来最复杂的火星探测器自拍照之一。在这张自拍照中，火星车的Mastcam-Z和SuperCam仪器正看着沃森和火星车伸出的手臂的末端。离毅力号大约4米（13英尺）的地方是一个机器人同伴，火星匠心号直升机。

On sol 46 (April 6, 2021) the Perseverance rover held out a robotic arm to take its first selfie on Mars. The WATSON camera at the end of the arm was designed to take close-ups of martian rocks and surface details though, and not a quick snap shot of friends and smiling faces. In the end, teamwork and weeks of planning on Mars time was required to program a complex series of exposures and camera motions to include Perseverance and its surroundings. The resulting 62 frames were composed into a detailed mosiac, one of the most complicated Mars rover selfies ever taken. In this version of the selfie, the rover's Mastcam-Z and SuperCam instruments are looking toward WATSON and the end of the rover's outstretched arm. About 4 meters (13 feet) from Perseverance is a robotic companion, the Mars Ingenuity helicopter.
