Abstract The MErcury Surface, Space ENvironment, GEochemistry, and Ranging
(MESSENGER) spacecraft, launched on August 3, 2004, is nearing the halfway point on its …

Recent planetary space missions, new experimental data, and advanced numerical
techniques have helped to improve our understanding of the deep interiors of the terrestrial …

We study numerically an extensive set of dynamo models in rotating spherical shells,
varying all relevant control parameters by at least two orders of magnitude. Convection is …

Observations of radar speckle patterns tied to the rotation of Mercury establish that the
planet occupies a Cassini state with obliquity of 2.11±0.1 arc minutes. The measurements …

Scaling laws are derived for the time-average magnetic dipole moment in rotating
convection-driven numerical dynamo models. Results from 145 dynamo models with a …

The Magnetometer (MAG) on the MErcury Surface, Space ENvironment, GEochemistry, and
Ranging (MESSENGER) mission is a low-noise, tri-axial, fluxgate instrument with its sensor …

The structure of Mercury's internal magnetic field has been determined from analysis of
orbital Magnetometer measurements by the MESSENGER spacecraft. We identified the …

Mercury has a global magnetic field of internal origin and it is thought that a dynamo
operating in the fluid part of Mercury's large iron core is the most probable cause. However …

The state of knowledge and understanding of planetary magnetic fields is reviewed. All of
the planets, with the possible exception of Venus, have had active dynamos at some time in …

A number of observations performed by the MESSENGER spacecraft can now be employed
to better understand the evolution of Mercury's interior. Using recent constraints on interior …
