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

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

$R$-process enhancements of Gaia-Enceladus in GALAH DR3 [PDF]

open access: bronzeA&A 650, A110 (2021), 2021
The dominant site of production of $r$-process elements remains unclear despite recent observations of a neutron star merger. Observational constraints on the properties of the sites can be obtained by comparing $r$-process abundances in different environments.

Survival strategies of an anoxic microbial ecosystem in Lake Untersee, a potential analog for Enceladus [PDF]

open access: yesScientific Reports, 2022
Lake Untersee located in Eastern Antarctica, is a perennially ice-covered lake. At the bottom of its southern basin lies 20 m of anoxic, methane rich, stratified water, making it a good analog for Enceladus, a moon of Saturn.

New Insights into Variations in Enceladus Plume Particle Launch Velocities from Cassini-VIMS Spectral Data [PDF]

open access: yesThe Planetary Science Journal, 2023
Enceladus’s plume consists mainly of a mixture of water vapor and solid ice particles that may originate from a subsurface ocean. The physical processes underlying Enceladus’s plume particle dynamics are still being debated, and quantifying the particles’

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

open access: yesLife, 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.

Variations in plume activity reveal the dynamics of water-filled faults on Enceladus [PDF]

open access: yesNature Communications
After discovering a jet activity near the south pole of Saturn’s moon Enceladus, the Cassini mission demonstrated the existence of a subsurface water ocean with a unique sampling opportunity through flybys.

A Potential Mushy Source for the Geysers of Enceladus and Other Icy Satellites

open access: yesGeophysical Research Letters
Enceladus is a target for astrobiology due to the H2O plume ejecta measured by the Cassini spacecraft and the inferred subsurface ocean that could be the source of the geysers.

A multi-lander New Frontiers mission concept study for Enceladus: SILENUS

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Enceladus, with its subsurface ocean, is amongst the top priority targets in the search for life beyond Earth. Following on discoveries from the Cassini mission that Enceladus possesses a global subsurface ocean containing salt and organic compounds ...

The ETNA mission concept: Assessing the habitability of an active ocean world

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Enceladus is an icy world with potentially habitable conditions, as suggested by the coincident presence of a subsurface ocean, an active energy source due to water-rock interactions, and the basic chemical ingredients necessary for terrestrial life ...
