First 3-D Map of Mars Magnetic Topology

Mars’ intense crustal magnetic sources give rise to complex magnetic fields. These fields either form closed loops (miniature magnetospheres) or connect with the interplanetary magnetic field to form cusps, as in the Earth’s polar regions. The first 3-D map of Mars magnetic topology has been determined from MAVEN SWEA/MAG data.
