The New Horizons spacecraft observed Jupiter's icy satellites Europa and Ganymede during its flyby in February and March 2007 at visible and infrared wavelengths. Infrared spectral images map H2O ice absorption and hydrated contaminants, bolstering the case for an exogenous source of Europa's “non-ice” surface material and filling large gaps in compositional maps of Ganymede's Jupiter-facing hemisphere. Visual wavelength images of Europa extend knowledge of its global pattern of arcuate troughs… Expand

ALMA Thermal Observations of a Proposed Plume Source Region on Europa
We present a daytime thermal image of Europa taken with the Atacama Large Millimeter Array. The imaged region includes the area northwest of Pwyll Crater, which is associated with a nighttime thermalExpand
Exospheric signatures of alkali abundances in Europa's regolith
[1] The sodium and potassium exospheres of Europa are described as well as the variations of the Na/K ratio from Europa's surface up to about 20 Europa radii. Observations carried out by M. E. BrownExpand
Salts and Radiation Products on the Surface of Europa
The surface of Europa could contain the compositional imprint of an underlying interior ocean, but competing hypotheses differ over whether spectral observations from the Galileo spacecraft show theExpand
Serendipitous infrared observations of Europa by Juno/JIRAM
Abstract We performed spectral analyses on four serendipitous observations of Europa acquired by the JIRAM instrument (Adriani et al., 2017) onboard the Juno mission. Due to the fixed orientation ofExpand
ALMA Thermal Observations of Europa
We present four daytime thermal images of Europa taken with the Atacama Large Millimeter Array. Together, these images comprise the first spatially resolved thermal dataset with complete coverage ofExpand

Abstract Ganymede's surface exhibits great geological diversity, with old dark terrains, expressed through the surface composition, which is known to be dominated by two constituents: H2O-ice and anExpand
Plasma, plumes and rings: Saturn system dynamics as recorded in global color patterns on its midsize icy satellites
New global maps of the five inner midsize icy saturnian satellites, Mimas, Enceladus, Tethys, Dione, and Rhea, have been constructed in three colors (UV, Green and near-IR) at resolutions of 1Expand
True polar wander on Europa from global-scale small-circle depressions
Two global-scale organized concentric antipodal sets of arcuate troughs and depressions up to hundreds of kilometres long and 300 m to ∼1.5 km deep are mapped, suggesting that many of Europa’s tectonic patterns may also be related to true polar wander. Expand
Bayesian analysis of Juno/JIRAM's NIR observations of Europa
Abstract Decades of observations of Europa's surface in the near-infrared (NIR), spanning spacecrafts like Galileo, Cassini and New Horizons, along with ground based observations, have revealed aExpand
New Horizons: Anticipated Scientific Investigations at the Pluto System
The New Horizons spacecraft will achieve a wide range of measurement objectives at the Pluto system, including color and panchromatic maps, 1.25–2.50 micron spectral images for studying surfaceExpand


Salts on Europa's surface detected by Galileo's near infrared mapping spectrometer. The NIMS Team.
Reflectance spectra obtained by Galileo's Near Infrared Mapping Spectrometer exhibit distorted water absorption bands that indicate the presence of hydrated minerals, and may represent evaporite deposits formed by water, rich in dissolved salts, reaching the surface from a water-rich layer underlying an ice crust.

Hydrated salt minerals on Europa's surface from the Galileo near‐infrared mapping spectrometer (NIMS) investigation
We reported evidence of heavily hydrated salt minerals present over large areas of Europa's surface from analysis of reflectance spectra returned by the Galileo mission near infrared mappingExpand
Amorphous and crystalline ice on the Galilean satellites: A balance between thermal and radiolytic processes
[1] The water ice on the three outermost Galilean satellites of Jupiter has a lattice structure that can vary from crystalline to amorphous. Amorphous ice is crystallized by heating, whileExpand
Is There Evidence for Polar Wander on Europa
Abstract The orientations of the albedo lineaments, bands, and lineations on Europa's surface have been compared in previous studies with the global stress fields set up by orbital eccentricity,Expand
Hydrated Salt Minerals on Ganymede's Surface: Evidence of an Ocean Below
Reflectance spectra from Galileo's near-infrared mapping spectrometer (NIMS) suggests that the surface of Ganymede, the largest satellite of Jupiter, contains hydrated materials that are similar to those found on Europa. Expand
Exogenic and endogenic albedo and color patterns on Europa

Abstract Ninety voyager images ranging in phase angle from 3 to 143° and covering the spectral range from 0.34 to 0.58 μm were analyzed to derive the photometric properties of Europa. At small phaseExpand

Two global issues regarding Europa are addressed by a survey of strike-slip faults. First, a common type of terrain that appears to represent convergent sites of surface removal, which may helpExpand
An experimental estimate of Europa's “ocean” composition independent of Galileo orbital remote sensing
