Triton: Topography and Geology of a Probable Ocean World with Comparison to Pluto and Charon
Remote Sensing, 2021 The topography of Neptune’s large icy moon Triton could reveal important clues to its internal evolution, but has been difficult to determine. New global digital color maps for Triton have been produced as well as topographic data for

Consequences of large impacts on Enceladus' core shape [PDF]
, 2015 International audienceThe intense activity on Enceladus suggests a differentiated interior consisting of a rocky core, an internal ocean and an icy mantle.

Survival of Organic Materials in Hypervelocity Impacts of Ice on Sand, Ice, and Water in the Laboratory [PDF]
, 2014 The survival of organic molecules in shock impact events has been investigated in the laboratory. A frozen mixture of anthracene and stearic acid, solvated in dimethylsulfoxide (DMSO), was fired in a two-stage light gas gun at speeds of ?2 and ?4?km s?1 ...

Magnetospheric considerations for solar system ice state [PDF]
, 2018 The current lattice configuration of the water ice on the surfaces of the inner satellites of Jupiter and Saturn is likely shaped by many factors. But laboratory experiments have found that energetic proton irradiation can cause a transition in the ...

Titan as an analog of Earth’s past and future
EPJ Web of Conferences, 2009 Titan, the second-largest moon in the solar system, is revealed by the joint ESA-NASA mission Cassini-Huygens to have a dense atmosphere of nitrogen and methane, lakes and seas of liquid methane and ethane, evidence for fluvial (river-based) erosion, and ...

The Survival Rate of Ejected Terrestrial Planets with Moons [PDF]
, 2007 During planet formation, a gas giant will interact with smaller protoplanets that stray within its sphere of gravitational influence. We investigate the outcome of interactions between gas giants and terrestrial-sized protoplanets with lunar-sized ...

The Young Age of the LAMP‐observed Frost in Lunar Polar Cold Traps
Geophysical Research Letters, 2019 The Lunar Reconnaissance Orbiter/Lyman Alpha Mapping Project (LAMP) ultraviolet instrument detected a 0.5–2% icy regolith mix on the floor of some of the southern pole permanently shadowed craters of the Moon. We present calculations indicating that most

Can large icy moons accrete undifferentiated? [PDF]
Icarus, 2014 The apparent moments of inertia of Callisto and Titan inferred from gravity data suggest incomplete differentiation of their interior, commonly attributed to slow and cold accretion. To understand whether such large icy moons can really avoid global melting and subsequent differentiation during their accretion, we have developed a 3D numerical model ...

Modeling Virus and Bacteria Populations in Europa’s Subsurface Ocean
Life, 2022 The search for life in the universe is often informed by the study of “extreme” environments on Earth, which provide analogs for habitable locations in the Solar System, and whose microbial inhabitants may therefore also serve as analogs for potential ...

Effect of the tiger stripes on the deformation of Saturn's moon Enceladus
Geophysical Research Letters, 2016 Enceladus is a small icy moon of Saturn with active jets of water emanating from fractures around the south pole, informally called tiger stripes, which might be connected to a subsurface water ocean.
