Q&A Europa Clipper mission [PDF]

open access: yesNature Communications
NASA’s latest space probe Europa Clipper, was launched on October 14, 2024, and will study Jupiter’s moon Europa. Europa is covered by an icy crust and is thought to host a subsurface ocean of liquid water. Europa Clipper’s main mission objectives are to

Near-infrared reflectance spectroscopy of sublimating salty ice analogues. Implications for icy moons [PDF]

open access: yes, 2022
The composition of the surface of the Galilean icy moons has been debated since the Galileo mission. Several chemistries have been proposed to explain the composition of the non-icy component of the moon's surfaces, notably, sulphuric acid hydrates and ...

Ceres’ Broad‐Scale Surface Geomorphology Largely Due To Asymmetric Internal Convection

open access: yesAGU Advances, 2022
While we now know much about the volatile‐rich world of Ceres from the Dawn mission, the deep interior remains something of an enigma, shrouded by a crust composed of water ice, carbonates, phyllosilicates, salts and clathrate hydrates.

Ammonia as a parameter shaping habitability on icy moons. [PDF]

open access: yesFEMS Microbes
Abstract The search for life now extends beyond the traditional habitable zone to include the icy moons of Jupiter and Saturn. These moons feature ice-covered surfaces overlying substantial oceans formed primarily of liquid water and other potential constituents, such as ammonia.

A Review on Hypothesized Metabolic Pathways on Europa and Enceladus: Space-Flight Detection Considerations

open access: yesLife, 2023
Enceladus and Europa, icy moons of Saturn and Jupiter, respectively, are believed to be habitable with liquid water oceans and therefore are of interest for future life detection missions and mission concepts. With the limited data from missions to these

The archaeal class Halobacteria and astrobiology: Knowledge gaps and research opportunities

open access: yesFrontiers in Microbiology, 2022
Water bodies on Mars and the icy moons of the outer solar system are now recognized as likely being associated with high levels of salt. Therefore, the study of high salinity environments and their inhabitants has become increasingly relevant for ...

Energetic Constraints on Ocean Circulations of Icy Ocean Worlds

open access: yesThe Planetary Science Journal, 2023
Globally ice-covered oceans have been found on multiple moons in the solar system and may also have been a feature of Earth’s past. However, relatively little is understood about the dynamics of these ice-covered oceans, which affect not only the ...

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

open access: yesIEEE 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

open access: yesThe 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 ...
