19th January 2017 Sol 1584

We have found another (the 4th) meteorite.  The fist sized sample called Ames_Knob – which was analysed by ChemCam – turns out to be composed of Fe and Ni metal. This iron meteorite looks like it fragmented in the martian atmosphere, producing fragments like Ames_Knob and Egg_Rock, Lebanon and Littleton. It is notably fresh and unaltered so may have fallen relative recently, within the last thousands of years perhaps.
