Mars Crustal Magnetic Field Remnants

This image shows especially strong Martian magnetic fields in the southern highlands near the Terra Cimmeria and Terra Sirenum regions, centered around 180 degrees longitude from the equator to the pole. It is where magnetic stripes possibly resulting from crustal movement are most prominent. The bands are oriented approximately east - west and are about 100 miles wide and 600 miles long, although the longest band stretches more than 1200 miles. The false blue and red colors represent invisible magnetic fields in the Martian crust that point in opposite directions. The magnetic fields appear to be organized in bands, with adjacent bands pointing in opposite directions, giving these stripes a striking similarity to patterns seen in the Earth's crust at the mid-oceanic ridges. These data were compiled by the MGS Magnetometer Team led by Mario Acuna at the Goddard Space Flight Center in Greenbelt, MD.plain2016-05-18T12:27:44+00:00Internet ArchivePLAN-PIA02819imageWhat -- TerraWhat -- Mars Global Surveyor Orbiter (MGS)What -- MagnetometerWhat -- MarsWhere -- Goddard Space Flight Center (GSFC)Mariek Schmidt3b678a5bd42eb8bf9a55fb761e5f17b11ce872c1
