One of the most interesting discoveries made so far by the Opportunity rover on Mars has been the small round spherules or "blueberries" as they are commonly referred to, covering the ground at the rover's landing site. Typically only a few millimetres across, some lie loose on the soil while others are imbedded in rock outcrops.
