Evolution of Mercury’s Earliest Atmosphere
MESSENGER observations suggest a magma ocean formed on proto-Mercury, during which evaporation of metals and outgassing of C- and H-bearing volatiles produced an early atmosphere. Atmospheric escape
Rationale for BepiColombo Studies of Mercury’s Surface and Composition
BepiColombo has a larger and in many ways more capable suite of instruments relevant for determination of the topographic, physical, chemical and mineralogical properties of Mercury’s surface than

Particles and Photons as Drivers for Particle Release from the Surfaces of the Moon and Mercury
The Moon and Mercury are airless bodies, thus they are directly exposed to the ambient plasma (ions and electrons), to photons mostly from the Sun from infrared range all the way to X-rays, and to
Early sulfur‐rich magmatism on the ungrouped achondrite Northwest Africa 7325 differentiated parent body
The ungrouped achondrite Northwest Africa (NWA) 7325 parent body underwent a severe impact after primary crystallization, which completely melted plagioclase and partially melted pyroxene, followed
Earthicle and Its Discontents: A Historical Critical Review of Iron (Oxide) Particles Singly and Doubly Shelled with Silica and/or Carbon
Earthicle was conceived as an astromimetic particle mimicking the stratified structure of Earth. Although earthicle can come in various compositional and structural forms, its seminal version consi...

The history of volcanism on Mercury is almost the entire history of the formation of its crust. There are no recognized tracts of intact primary crust analogous to the Moon’s highland crust, probably
A low O/Si ratio on the surface of Mercury: Evidence for silicon smelting?
Data from the Gamma‐Ray Spectrometer (GRS) that flew on the MErcury Surface, Space ENvironment, GEochemistry, and Ranging spacecraft indicate that the O/Si weight ratio of Mercury's surface is 1.2 ±
Silicate mineralogy at the surface of Mercury
NASA’s MESSENGER spacecraft has revealed geochemical diversity across Mercury’s volcanic crust. Near-infrared to ultraviolet spectra and images have provided evidence for the Fe2+-poor nature of
Evidence from MESSENGER for sulfur‐ and carbon‐driven explosive volcanism on Mercury
Targeted MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) X‐Ray Spectrometer measurements of Mercury's largest identified pyroclastic deposit are combined with neutron and
Remote sensing evidence for an ancient carbon-bearing crust on Mercury
Mercury appears darker globally than expected. Remote sensing evidence from the MESSENGER spacecraft indicates that the planet’s darkening agent is carbon and suggests that it originates from an
