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)

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.

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

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

Q&A Europa Clipper mission [PDF]
Nature CommunicationsNASA’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

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

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

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