High-pressure experimental constraints of partitioning behavior of Si and S at the Mercury's inner core boundary
Abstract The partitioning of light elements between liquid and solid at the inner core boundary (ICB) governs compositional difference and density deficit between the outer and inner core.
Mercury Lander: Planetary Mission Concept Study for the 2023-2032 Decadal Survey
As an end-member of terrestrial planet formation, Mercury holds unique clues about the original distribution of elements in the earliest stages of solar system development and how planets and
The Inner Solar System Chronology (ISOCHRON) Lunar Sample Return Mission Concept: Revealing Two Billion Years of History
We present the Inner SOlar System CHRONology (ISOCHRON) concept to return samples of the youngest extensive mare basalt for age-dating and geochemical analysis. The young basalt is exposed at a site
Revolutionizing Our Understanding of the Solar System via Sample Return from Mercury
Data from Mariner 10, MESSENGER, and ground-based telescopic observations have facilitated great advancements towards understanding the geochemistry, geology, internal structure, exosphere, and


Earth's inner core nucleation paradox
Abstract The conventional view of Earth's inner core is that it began to crystallize at Earth's center when the temperature dropped below the melting point of the iron alloy and has grown steadily
MESSENGER observations of induced magnetic fields in Mercury's core
Orbital data from the Magnetometer on the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft allow investigation of magnetic fields induced at the top of Mercury's
Magnetic anomalies concentrated near and within Mercury's impact basins: Early mapping and interpretation
Ninety-five low-altitude passes of MErcury Surface, Space ENvironment, GEochemistry, and Ranging magnetometer data from February, March, and April of 2015 have been applied to produce an approximate
Magnetic mineralogy of the Mercurian lithosphere
Mercury and Earth are the only inner solar system planets with active, internally generated dynamo magnetic fields. The MESSENGER mission recently detected magnetic fields on Mercury that are
Melting processes and mantle sources of lavas on Mercury
Abstract The MESSENGER spacecraft provided geochemical data for surface rocks on Mercury. In this study, we use the major element composition of these lavas to constrain melting conditions and
Low-altitude magnetic field measurements by MESSENGER reveal Mercury’s ancient crustal field
Results indicate that a global magnetic field driven by dynamo processes in the fluid outer core operated early in Mercury’s history, and infer a lower bound on the average age of magnetization of 3.7 to 3.9 billion years.
Support of long-wavelength topography on Mercury inferred from MESSENGER measurements of gravity and topography
To explore the mechanisms of support of surface topography on Mercury, we have determined the admittances and correlations of topography and gravity in Mercury's northern hemisphere from measurements
Thickness of the crust of Mercury from geoid-to-topography ratios
To gain insight into the thickness of the crust of Mercury, we use gravity and topography data acquired by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging spacecraft to calculate
Constraints on the secular variation of Mercury's magnetic field from the combined analysis of MESSENGER and Mariner 10 data
Observations of Mercury's internal magnetic field from the Magnetometer on the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft have revealed a dipole moment of
