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.
