Mars Anomaly - 3 Iron Balls on Mars side by side!! NASA Curiosity Image

Friends... This image surprised me. There are Three iron balls each side by side with nearly same distance. First i found the big one ( Right Side ) Then the middle one, after deep searching, i found the third one ( Left side )
Sand dust on Mars closed these balls. May be they are in same size and same weight. Who put them there? Are they formed naturally? I feel they are iron balls but that is also a mystery. Click on above original image. Zoom-in that and see all three balls yourself or click source link and see original NASA Curiosity's Cute Image.
