An Approach Based on Multiobjective Genetic Algorithms to Schedule Observations in Planetary Remote Sensing Missions

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Data acquisition in planetary remote sensing missions is influenced by complex environmental resource- and instrument-specific constraints. This impedes to perform observations at any given time during the mission and with any of the instruments ...

A Recent Impact Origin of Saturn’s Rings and Mid-sized Moons

The Astrophysical Journal, 2023
We simulate the collision of precursor icy moons analogous to Dione and Rhea as a possible origin for Saturn’s remarkably young rings. Such an event could have been triggered a few hundred million years ago by resonant instabilities in a previous ...

Possibility for albedo estimation of exomoons: Why should we care about M dwarfs? [PDF]

, 2016
Occultation light curves of exomoons may give information on their albedo and hence indicate the presence of ice cover on the surface. Icy moons might have subsurface oceans thus these may potentially be habitable.

Surface charging of thick porous water ice layers relevant for ion sputtering experiments [PDF]

, 2016
We use a laboratory facility to study the sputtering properties of centimeter-thick porous water ice subjected to the bombardment of ions and electrons to better understand the formation of exospheres of the icy moons of Jupiter.

The Diverse Solar Phase Curves of Distant Icy Bodies. II. The Cause of the Opposition Surges and Their Correlations [PDF]

, 2008
We collect well-measured opposition surge properties for many icy bodies orbiting the Sun (mostly from our own observations) plus for many icy moons, resulting in a data base of surface and orbital properties for 52 icy bodies.

Plume Sample Modification at Icy Moons: Implications for Biosignatures

Frontiers in Astronomy and Space Sciences, 2020
Water from the plumes of icy moons is a potential sampling target that may preserve the aqueous chemistry of the interior oceans, as well as organics and other biosignatures or prebiotic chemical precursors.

Revealing the Interior Structure of Icy Moons with a Bayesian Approach to Magnetic Induction Measurements

The Planetary Science Journal, 2023
Some icy moons and small bodies in the solar system are believed to host subsurface liquid water oceans. The interaction of these saline, electrically conductive oceans with time-varying external magnetic fields generates induced magnetic fields ...

New Signatures of Bio-Molecular Complexity in the Hypervelocity Impact Ejecta of Icy Moon Analogues

Life, 2022
Impact delivery of prebiotic compounds to the early Earth from an impacting comet is considered to be one of the possible ways by which prebiotic molecules arrived on the Earth.

PlanetProfile: Self‐Consistent Interior Structure Modeling for Ocean Worlds and Rocky Dwarf Planets in Python

Earth and Space Science, 2023
The open‐source PlanetProfile framework was developed to investigate the interior structure of icy moons based on collectively matching their observed properties and comparative planetology.

Active-passive microwave scattering in the Antarctica wind-glazed region: an analog for icy moons of Saturn [PDF]

The Cryosphere
Microwave radiometry and scatterometry, two complementary modes of sensing the composition and structure of the upper meters to hundreds of meters of the subsurface, are often difficult to reconcile, both on the Earth cryosphere and on icy moons of ...
