A local Martian crustal field model: Targeting the candidate landing site of the 2020 Chinese Mars Rover

open access: yesEarth and Planetary Physics, 2020
Unlike Earth, Mars lacks a global dipolar magnetic field but is dominated by patches of a remnant crustal magnetic field. In 2021, the Chinese Mars Rover will land on the surface of Mars and measure the surface magnetic field along a moving path within ...
