Thermal picks for anchoring on icy moons [PDF]

Heliyon, 2019
Europa, Enceladus, and other icy moons are exciting science targets, but our capabilities to adequately explore these planetary bodies needs to be developed.

Spectroscopic Detection of Biosignatures in Natural Ice Samples as a Proxy for Icy Moons [PDF]

Life, 2023
Some of the icy moons of the solar system with a subsurface ocean, such as Europa and Enceladus, are the targets of future space missions that search for potential extraterrestrial life forms.

Jupiter Science Enabled by ESA's Jupiter Icy Moons Explorer. [PDF]

Space Sci Rev, 2023
AbstractESA’s Jupiter Icy Moons Explorer (JUICE) will provide a detailed investigation of the Jovian system in the 2030s, combining a suite of state-of-the-art instruments with an orbital tour tailored to maximise observing opportunities. We review the Jupiter science enabled by the JUICE mission, building on the legacy of discoveries from the Galileo,

Crystallography relevant to Mars and Galilean icy moons: crystal behavior of kieserite-type monohydrate sulfates at extraterrestrial conditions down to 15 K [PDF]

IUCrJ, 2022
Monohydrate sulfate kieserites (M2+SO4·H2O) and their solid solutions are essential constituents on the surface of Mars and most likely also on Galilean icy moons in our solar system. Phase stabilities of end-member representatives (M2+ = Mg, Fe, Co, Ni)

Implications of high-pressure oxygen hydrates on radiolytic oxygen in Jovian icy moons [PDF]

Communications Chemistry
Various icy moons, such as Europa and Ganymede, have thin oxygen atmospheres and exhibit spectral features attributed to oxygen held in their surface ices. The oxygen forms from the radiolysis of water.

How to Detect Life on Icy Moons. [PDF]

Astrobiology, 2018
The icy moons of the outer Solar System present the possibility of subsurface water, habitable conditions, and potential abodes for life. Access to evidence that reveals the presence of life on the icy moons can be facilitated by plumes that eject material from the subsurface out into space.

Growth, physiology, and metabolism of Halomonas meridiana in aqueous ammonium sulfate with implications for icy moon astrobiology [PDF]

Frontiers in Microbiology
The discovery of extraterrestrial reservoirs of liquid water has motivated missions to icy moons Europa and Titan. Tentative evidence of ammonium sulfate ((NH4)2SO4) has been detected on the surface of Europa, and (NH4)2SO4 could be a prominent ...

Lateral melt variations induce shift in Io’s peak tidal heating [PDF]

Nature Communications
The innermost Galilean moon, Io, exhibits widespread tidally-driven volcanism. Monitoring of its volcanoes has revealed that they are not homogeneously distributed across its surface: volcanic activity is higher at low latitudes and peaks east of the sub-

Q&A Europa Clipper mission [PDF]

Nature 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

An astrobiological perspective on microbial biofilms: their importance for habitability and production of detectable and lasting biosignatures [PDF]

Applied and Environmental Microbiology
The search for life elsewhere in the universe has remained one of the main goals of astrobiological exploration. In this quest, extreme environments on Earth have served as analogs to study the potential habitability of Mars and icy moons, which include ...
