{Why is much of the surface of Mars covered with red iron oxide dust when the rocks that compose much of its surface are blue or violet? - Mars has been systematically bombarded with small iron-nickel meteorites or micrometeorites that oxidize in its atmosphere - Mars has been frequently bombarded with hematite containing micrometeorites - asteroid impacts on Mars may have forced iron from near its core into the atmosphere and onto the surface as hematite dust that oxidized - Mars is like Earth in surface hematite composition, but Earth has much more water + precipitation from iron-rich water
