Mars Has Far Fewer Minerals Than Earth Does
The development of plate tectonics and life on Earth provided avenues for mineral evolution that did not occur on Mars, resulting in relatively limited mineral diversity on the Red Planet.

A Mystery About the Moon’s Deep Interior Endures
Geophysical data has suggested that the base of the Moon’s mantle is partially molten or contains ilmenite, but an improved rheology model puts the existence of this layer in doubt.
