Perseverance Selfie with Ingenuity

Explanation: 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.

说明: 在第46个火星日（地球历2021年4月6日）那天，毅力号伸展机械臂，并拍下它在火星的第一幅自拍照。不过，位在臂尖的华生相机，是设计用来拍摄火星岩石和火星表面的特写和细微结构，并不擅长记录好友及笑脸之类的生活照。所以，得用大量的团队合作及数个火星周的规划，并历经复杂的拍照程序和相机移动，才拍下毅力号及其周围的景观。所得的62张照片，然后再组合出一幅细致、至今最复杂的火星车自拍照之一。在上面这个版本的自拍照里，毅力号的桅杆Z及超级成像分析仪，正好面对这部火星车外伸机械臂尖的华生相机。大约在4米之外，可见到毅力号的伙伴——机智号火星直升机。
