Determination of the Mercury’s Internal Dipole Parameters using MESSENGER Spacecraft Data

Key Points

The aim is to refine Mercury’s planetary dipole parameters using data from the MESSENGER spacecraft.
Analyzed magnetic equatorial plane crossings during MESSENGER flybys.
Assessed interplanetary magnetic field (IMF) direction and magnitude.
Refined dipole offset calculations for multiple orbits.
Determined precise dipole offsets for each orbit of MESSENGER.
Identified the influence of the IMF on dipole position adjustments.
Refined previously established dipole parameters, especially in low IMF conditions.

Abstract

Using data on Mercury’s magnetic equatorial plane crossings by the MESSENGER spacecraft, we refine the position of Mercury’s planetary dipole. Magnetic equatorial plane crossings provide precise dipole offsets for each orbit. Using data on the interplanetary magnetic field (IMF) magnitude and direction during MESSENGER flybys, we determine the influence of the IMF on the equatorial plane crossing position and refine the previously determined dipole offset for orbits with insignificant IMF contributions.
