Planetary science intern leads study of Martian crust
E-Mail The planet Mars has no global magnetic field, although scientists believe it did have one at some point in the past. Previous studies suggest that when Mars' global magnetic field was present, it was approximately the same strength as Earth's current field. Surprisingly, instruments from past Mars missions, both orbiters and landers, have spotted patches on the planet's surface that are strongly magnetized--a property that could not have been produced by a magnetic field similar to Earth's, assuming the rocks on both planets are similar.
