   Explanation: On sol 46 (April 6, 2021) the Perseverance rover held out
   a robotic arm to take [6]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, [7]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
   [8]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, [9]the Mars
   Ingenuity helicopter.
