Planetary Bistatic Radar [PDF]

, 2018
Planetary radar observations offer the potential for probing the properties of characteristics of solid bodies throughout the inner solar system and at least as far as the orbit of Saturn.

Energy and Temperature Dependencies for Electron-induced Sputtering from H2O Ice: Implications for the Icy Galilean Moons

The Planetary Science Journal
To better assess the role that electrons play in exosphere production on icy bodies, we measured the total and O _2 sputtering yields from H _2 O ice for electrons with energies between 0.75 and 10 keV and temperatures between 15 and 124.5 K.

Galileo to Jupiter: Probing the Planet and Mapping Its Moons [PDF]

The first project to use the space shuttle as an interplanetary launch vehicle, the Galileo mission is designed to obtain information about the origin and evolution of the solar system by studying large-scale phenomena on Jupiter and its satellites ...

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.

Spectroscopic Mapping of Callisto with HST/STIS and Implications for its Surface Composition

The Planetary Science Journal
We present global, spatially resolved ultraviolet–visible spectra of Callisto obtained with the Hubble Space Telescope/Space Telescope Imaging Spectrograph and explore possible compositions of Callisto’s surface material.

Orbit improvement of the satellites of the outer planets [PDF]

Data reduced from 127 plates showing Jupiter's and Saturn's satellites in the interval 1972 to 1974 are available on computer cards in the form of (O-C) residuals.

A Direct Simulation Monte Carlo–Driven Photochemical Model of Callisto’s Ionosphere

The Planetary Science Journal
Here we present a photochemical model of Callisto’s ionosphere with inputs supplied by a direct simulation Monte Carlo model of its neutral atmosphere. We compare a model that considers interactions with photons as the sole external ionization mechanism ...
