Mars crustal magnetism as measured by Mars global Surveyor:
I noticed the resemblance of parts of it to satellite tracks, but they are somewhat off center. So I tried NASA's GISS map projector, and playing a hunch used the antipodes of the Borealis Basin as the center: Has anyone read anything explaining why the curves they make should be roughly centered at the basin's antipodes? |
