Between 1965 and 1975, our knowledge of Mercury and its physical characteristics improved dramatically. Radar studies of the planetary orbit and rotation rate and Mariner 10 spacecraft studies of its surface, atmosphere, magnetic field and plasma environment provided startling new results on what had been the least understood member of the terrestrial planets. With a highly cratered surface and a modest magnetic field, Mercury is a differentiated planet with fractionally the largest iron core… Expand
Space Exploration of Planetary Magnetism
This chapter gives a brief overview of the major observational advances in our quantitative knowledge of the intrinsic magnetic fields of the 8 planets, except Earth, from Mercury to Neptune, sinceExpand
On electromagnetic phenomena in Mercury’s magnetosphere
Mercury has a small but intriguing magnetosphere. In this brief review, we discuss some similarities and differences between Mercury's and Earth's magnetospheres. In particular, we discuss howExpand
Particle populations in Mercury's magnetosphere
Observations by Mariner 10 during its first and third flybys showed that Mercury possesses an intrinsic magnetic field resulting in a small magnetosphere that can keep the solar wind from directlyExpand
Planetary and lunar magnetism
In situ studies by spacecraft of the magnetic fields of Earth and all the planets except for Pluto began with the USSR’s launch of Sputnik 3 in 1958. The study of the geomagnetic field by the USAExpand
MERCURY: MAGNETIC FIELD AND MAGNETOSPHERE
Mercury is the smallest of the terrestrial planets. Its radius of 2440 km places it between the Earth's Moon and Mars in size. It is of great importance to those studying planetary magnetic dynamosExpand
Planetary Magnetic Field Measurements: Missions and Instrumentation
The nature and diversity of the magnetic properties of the planets have been investigated by a large number of space missions over the past 50 years. It is clear that without the magnetic fieldExpand
Recent advances in planetary magnetism
During the past decade, significant advances in thein situ measurements of planetary magnetic fields have been made. The U.S.A. and U.S.S.R. have conducted spacecraft investigations of all theExpand
Mercury's exosphere origins and relations to its magnetosphere and surface
Abstract Mariner 10, the only spacecraft that ever passed close to Mercury, revealed several unexpected characteristics: an intrinsic magnetosphere, the highest mean density of any Solar SystemExpand
Plasma Dynamics in Mercury's Magnetosphere
Mercury is in all sense of the words still Terra Incognito, its magnetosphere is hence little known. The only source of knowledge came from the in-situ measurements by the Mariner 10 close encountersExpand
Induced magnetic field effects at planet Mercury
Abstract At Mercury's surface external magnetic field contributions caused by magnetospheric current systems play a much more important role than at Earth. They are subjected to temporal variationsExpand

The magnetic fields of the terrestrial planets
Abstract A single model for the terrestrial planets based upon the structure inferred for the lunar interior is developed, which subdivides them according to size. It is probable that planetaryExpand
Observations of Mercury's magnetic field
This paper presents a study of magnetic field data obtained by Mariner 10 during the third and final encounter with the planet Mercury on 16 March 1975. A well developed bow shock and modestExpand
Implications of an internal dynamo for the thermal history of Mercury
Abstract The dynamo explanation of Mercury's magnetic field leads to constraints on the thermal evolution of the planet. A heat-source density at least comparable to the Earth's mantle-wide averageExpand
Does Mercury have a molten core?
THE Mariner 10 mission has discovered a magnetic field associated with the planet Mercury1. The preferred explanation of the source of this field based on these observations, is an internal dynamo2.Expand

TLDR
The complete body of data favors the preliminary conclusion that Mercury has an intrinsic magnetic field, which represents a major scientific discovery in planetary magnetism and will have considerable impact on studies of the origin of the solar system. Expand
Speculations on the origin of the magnetic field of Mercury
Abstract The intrinsic magnetic field of Mercury may be generated by a dynamo process in a liquid core, despite the planet's slow rotation rate. It is argued that, provided the core of Mercury isExpand
Does Mercury have a molten core?
THE discovery of an intrinsic magnetic field for the planet Mercury by Mariner 10 (ref. 1) and its preferred source in an internal dynamo2 imply the existence of a conducting molten core. We proposeExpand
Dynamo generation in Mercury
OBSERVATIONS during the most recent encounter of the planet Mercury by Mariner 10 seem to have confirmed the existence of a small but intrinsic magnetic dipole of about 3×10−3 gauss RM3, where RM isExpand
Rotation Period of the Planet Mercury
THE recent radar measurements of Mercury indicate that the period of rotation of the planet is 59 ± 5 days1. This result is in complete disagreement with the previously quoted value of 88 days basedExpand
