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 ...

Enceladus as a potential oasis for life: Science goals and investigations for future explorations [PDF]

open access: yes, 2021
Enceladus is the first planetary object for which direct sampling of a subsurface water reservoir, likely habitable, has been performed. Over a decade of flybys and seven flythroughs of its watery plume, the Cassini spacecraft determined that Enceladus ...

Astrobiology eXploration at Enceladus (AXE): A New Frontiers Mission Concept Study

open access: yesThe Planetary Science Journal, 2023
The Saturnian moon Enceladus presents a unique opportunity to sample the contents of a subsurface liquid water ocean in situ via the continuous plume formed over its south polar terrain using a multi-flyby mission architecture.

The Case for a Return to Enceladus [PDF]

open access: yes, 2021
The plume of Enceladus provides access to fresh material from a habitable, subsurface ocean. We summarize in this white paper the evidence for Enceladus’ ocean and its habitability, identify constraints and outstanding questions on the detectability of ...

The Science Case for a Return to Enceladus [PDF]

open access: yes, 2021
The plume of Enceladus is unique in the solar system in providing direct access to fresh material from an extraterrestrial subsurface ocean. The Cassini Mission, though not specifically designed for it, was able to take advantage of the plume to ...

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

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.

The pH of Enceladus’ ocean [PDF]

open access: yesGeochimica et Cosmochimica Acta, 2015
Observational data from the Cassini spacecraft are used to obtain a chemical model of ocean water on Enceladus. The model indicates that Enceladus' ocean is a Na-Cl-CO3 solution with an alkaline pH of ~11-12. The dominance of aqueous NaCl is a feature that Enceladus' ocean shares with terrestrial seawater, but the ubiquity of dissolved Na2CO3 suggests ...

Moonraker -- Enceladus Multiple Flyby Mission [PDF]

open access: yes, 2022
Enceladus, an icy moon of Saturn, possesses an internal water ocean and jets expelling ocean material into space. Cassini investigations indicated that the subsurface ocean could be a habitable environment having a complex interaction with the rocky core.

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

A GLOBAL SHAPE MODEL FOR SATURN’S MOON ENCELADUS FROM A DENSE PHOTOGRAMMETRIC CONTROL NETWORK [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
A planetary body’s global shape provides both insight into its geologic evolution, and a key element of any Planetary Spatial Data Infrastructure (PSDI). NASA’s Cassini mission to Saturn acquired more than 600 moderate- to high-resolution images (<500
