The Near-infrared Spectral Characteristics of Water Ice, Epsomite, and Halite Mixtures Relevant to Europa

The Planetary Science Journal
We publish the first near-infrared spectra of grain particulate mixtures of water ice, epsomite, and halite at cryogenic temperatures. Furthermore, we perform a quantitative assessment of the ability of both intimately and linearly mixed models to ...

Tidal Seismicity in the Moon and Implications for the Rocky Interior of Europa

The Planetary Science Journal
Seismology is a powerful tool for probing the deep interiors of planetary bodies. Just as deep moonquakes triggered by Earth’s tides occur on the Moon, as observed by the Apollo seismometers, icy moons of the giant planets may also have seismically ...

Ring particle sizes and composition derived from eclipse cooling curves and reflection spectra [PDF]

The probable chemistry of the Saturn rings is reviewed. Reflectance spectra for H20 and NH3 frosts and Saturn's rings are compared, along with temperature dependence of 1.6 microns water frost feature.

On the Divergent Evolution of Io and Europa as Primordial Ocean Worlds

The Astrophysical Journal
The Galilean moons exhibit a decrease in bulk density with distance from Jupiter, which may reflect differences in evolutionary paths and water loss. Early in its history, Jupiter was more luminous, which may have driven substantial atmospheric escape on

On the Origin and Dynamical Evolution of Jupiter’s Moon Amalthea

The Astrophysical Journal
Interior to the orbits of Jupiter’s iconic Galilean moons are four small satellites with individual mean radii R  ≲ 84 km. Multiple lines of evidence suggest that these bodies formed at a more distant location in Jupiter’s circumplanetary disk before ...

Global Distribution of the Key Species on the Surface of Europa

The Astrophysical Journal
The icy surface of Europa is continuously bombarded by ions and electrons from Jupiter’s magnetosphere. The bombardment of the particles dissociates water molecules on the surface of Europa and introduces impurities to the icy surface.
