MrSeb writes: "A few hundred million miles away on the surface of the Red Planet, Mars rover Curiosity has discovered an unidentified, shiny, metallic object. Now, before you get too excited, the most likely explanation is that bright object is part of the rover that has fallen off — or perhaps some debris from MSL Curiosity’s landing on Mars, nine weeks ago. There is the distinct possibility, however, that this object is actually native to Mars, which would be far more exciting. It could be the tip of a larger object, or perhaps some kind of exotic, metallic Martian pebble (a piece of metal ore, perhaps). Close-up imagery will now be captured and analyzed, and within the next few days we should know if it's simply a piece of Curiosity — or something a whole lot more exciting indeed."
