Observations by MESSENGER show that Mercury's magnetosphere is immersed in a comet-like cloud of planetary ions. The most abundant, Na+, is broadly distributed but exhibits flux maxima in the magnetosheath, where the local plasma flow speed is high, and near the spacecraft's closest approach, where atmospheric density should peak. The magnetic field showed reconnection signatures in the form of flux transfer events, azimuthal rotations consistent with Kelvin-Helmholtz waves along the… 
MESSENGER observations of Mercury's magnetosphere during northward IMF
[1] MESSENGER's January 14, 2008, flyby of Mercury has provided new observations of the planet's magnetosphere for northward interplanetary magnetic field (IMF). The dusk magnetopause was located
First Observations of Mercury's Plasma Mantle by MESSENGER†
We present the first observations of Mercury's plasma mantle, a primary region for solar wind entry into the planetary magnetosphere, located in the high-latitude magnetotail. MESSENGER observations

The nature of magnetic reconnection in planetary magnetospheres may differ between various planets. We report the first observations of a rapidly evolving magnetic reconnection process in Mercury's
MESSENGER observations of magnetopause structure and dynamics at Mercury
[1] On 18 March 2011, MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) became the first spacecraft to orbit Mercury, providing a new opportunity to study the outer boundary
Kinetic instabilities in Mercury's magnetosphere: Three-dimensional simulation results
[1] A self-consistent global three-dimensional kinetic study of Mercury's magnetosphere is carried out examining waves and instabilities generated by ion temperature anisotropy and plasma flow. The
Observations of Kelvin‐Helmholtz waves along the dusk‐side boundary of Mercury's magnetosphere during MESSENGER's third flyby
[1] During the third MESSENGER flyby of Mercury on 29 September 2009, 15 crossings of the dusk-side magnetopause were observed in the magnetic field data over a 2-min period, during which the
The Structure of Mercury's Magnetic Field from MESSENGER's First Flyby
TLDR
During its first flyby of Mercury, the MESSENGER spacecraft measured the planet's near-equatorial magnetic field, consistent to within an estimated uncertainty of 10% with that observed near the equator by Mariner 10.
Structure and dynamics of Mercury's magnetospheric cusp: MESSENGER measurements of protons and planetary ions
The MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft has observed the northern magnetospheric cusp of Mercury regularly since the probe was inserted into orbit
Ion dynamics during compression of Mercury's magnetosphere
Abstract. Because of the small planetary magnetic field as well as proximity to the Sun that leads to enhanced solar wind pressure as compared to Earth, the magnetosphere of Mercury is very dynamical

A quantitative model of the planetary Na + contribution to Mercury’s magnetosphere
Abstract. We examine the circulation of heavy ions of planetary origin within Mercury’s magnetosphere. Using single particle trajectory calculations, we focus on the dynamics of sodium ions, one of
Search for pick‐up ion generated Na+ cyclotron waves at Mercury
[1] Magnetometer data was examined from the two Mariner 10 passages through Mercury's magnetosphere for evidence of Na+ electromagnetic ion cyclotron waves (ICW). These waves are expected to be
Initial ISEE magnetometer results: magnetopause observations
The magnetic field profiles across the magnetopause obtained by the ISEE-1 and -2 spacecraft separated by only a few hundred kilometers are examined for four passes. During one of these passes the

During MESSENGER's first Mercury flyby, the Mercury Atmospheric and Surface Composition Spectrometer measured Mercury's exospheric emissions, including those from the antisunward sodium tail, calcium
Plasma entry from the flanks of the near‐Earth magnetotail: Geotail observations
Geotail observations of the low-latitude boundary layer (LLBL) in the near–Earth tail flanks are reported. Cold-dense stagnant ions, which are likely to be of the magnetosheath origin, are detected

MESSENGER Observations of the Composition of Mercury's Ionized Exosphere and Plasma Environment
TLDR
The MESSENGER spacecraft's observations of Mercury's ionized exosphere during its first flyby yielded Na+, O+, and K+ abundances, consistent with expectations from observations of neutral species.
