Juice-SWI during the Lunar-Earth-Gravity-Assist (LEGA) – Part 2: Instrument operations [PDF]

Annales Geophysicae
The Jupiter Icy Moons Explorer (Juice) embarked in 2023 on a 8-year interplanetary journey to Jupiter and its icy moons. The Submillimetre Wave Instrument (SWI) is one of the ten science instruments aboard the spacecraft. SWI is a sophisticated and first-

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.

Review of Saturn's icy moons following the Cassini mission [PDF]

, 2018
We review our knowledge of the icy moons of Saturn prior to the Cassini orbital mission, describe the discoveries made by the instrumentation onboard the Cassini ...

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.

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 ...

Evolution of Amino Acids in Icy Astrochemical Environments [PDF]

EPJ Web of Conferences
This study investigates the behaviour and evolution of amino acids under simulated astrophysical conditions, such as those found in the Interstellar Medium and icy moons like Europa.

Observation of nuclear quantum effects and hydrogen bond symmetrisation in high pressure ice

Nature Communications, 2018
Hydrogen atoms in water ices, under pressures at which they might exist in ocean exoplanets and icy moons, exhibit dynamics that are still poorly understood. Here, 1H-NMR experiments approaching the Mbar range shed light on the symmetrisation of hydrogen

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.

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 ...

7. Moons of small bodies

, 2015
The small bodies of our Solar System consist of: asteroids (rocky or carbonaceous objects that are mainly concentrated in the space between the orbits of Mars and Jupiter); trans-Neptunian objects (icy bodies beyond Neptune’s orbit); comets (small icy ...
