Near Infrared Interferometry of the Galilean Satellites [PDF]

International Astronomical Union Colloquium, 1979
AbstractSome of the Galilean satellites show evidence of two distinct surface types, a high albedo frost and a dark, presumably silicate material. We are beginning a program to map the spatial distribution of these components with a Michel son spatial interferometer. This will be done both in and next to the 2.0µm frost absorption band.

Laboratory Investigation of CO2-driven Enhancement of Radiolytic H2O2 on Europa and Other Icy Moons

The Planetary Science Journal
Observations of Europa’s leading hemisphere reveal elevated H _2 O _2 in the warmer, low-latitude chaos terrains compared to the colder, polar regions.

Constraints from deuterium on the formation of icy bodies in the Jovian system and beyond

, 2008
We consider the role of deuterium as a potential marker of location and ambient conditions during the formation of small bodies in our Solar system. We concentrate in particular on the formation of the regular icy satellites of Jupiter and the other ...

Stability of water on the Galilean satellites [PDF]

The selective loss of water from Io under currently prevailing physical conditions was studied to determine whether a large quantity of water can be lost from the satellite over the lifetime of the solar system. Loss processes considered include: thermal

Giant impacts in the Saturnian System: a possible origin of diversity in the inner mid-sized satellites

, 2011
It is widely accepted that Titan and the mid-sized regular satellites around Saturn were formed in the circum-Saturn disk. Thus, if these mid-sized satellites were simply accreted by collisions of similar ice-rock satellitesimals in the disk, the ...

Report of the Terrestrial Bodies Science Working Group. Volume 7: The Galilean satellites [PDF]

The formational and evolutionary history of natural satellites, their mineralogical composition and other phenomena of scientific interest are discussed. Key scientific questions about IO, Ganymede, Callisto, and Europa are posed and the measurements and

Orbital resonances, unusual configurations and exotic rotation states among planetary satellites [PDF]

Several examples of satellite dynamics are presented where significant progress has been made in understanding a complex problem, where a long-standing problem has finally been solved, where newly discovered configurations have motivated novel ...

Pwyll and Manannán Craters as a Laboratory for Constraining Irradiation Timescales on Europa

The Planetary Science Journal
We examine high-spatial-resolution Galileo/Near-Infrared Mapping Spectrometer observations of the young (∼1 My–∼20 My) impact features, Pwyll and Manannán craters, on Europa’s trailing hemisphere in an effort to constrain irradiation timescales.
