Experimental and simulation efforts in the astrobiological exploration of exooceans [PDF]
, 2020 The icy satellites of Jupiter and Saturn are perhaps the most promising places in the Solar System regarding habitability. However, the potential habitable environments are hidden underneath km-thick ice shells.

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

Ground-based detection of a cloud of methanol from Enceladus: When is a biomarker not a biomarker? [PDF]
, 2017 Saturn's moon Enceladus has vents emerging from a sub-surface ocean, offering unique probes into the liquid environment. These vents drain into the larger neutral torus in orbit around Saturn. We present a methanol (CH3OH) detection observed with IRAM 30-

Particle entrainment and rotating convection in Enceladus’ ocean
Communications Earth & Environment, 2023 Observations from Cassini have identified nanometer-sized silica grains in Saturn’s E-ring although their origin is unclear. Tidal deformation within Enceladus’ silicate core has been predicted to generate hot hydrothermal fluids that rise from the core ...

Enceladus: Cassini observations and implications for the search for life [PDF]
, 2006 Aims. The recent Cassini discovery of water vapor plumes ejected from the south pole of the Saturnian satellite, Enceladus, presents a unique window of opportunity for the detection of extant life in our solar system. Methods.

Enceladus as a Potential Niche for Methanogens and Estimation of Its Biomass
Life, 2021 Enceladus is a potential target for future astrobiological missions. NASA’s Cassini spacecraft demonstrated that the Saturnian moon harbors a salty ocean beneath its icy crust and the existence and analysis of the plume suggest water–rock reactions ...

A Sensitivity Study of the Enceladus Torus [PDF]
, 2009 We have developed a homogeneous model of physical chemistry to investigate the neutral-dominated, water-based Enceladus torus. Electrons are treated as the summation of two isotropic Maxwellian distributions$-$a thermal component and a hot component. The

Predicting the Effect of Surface Properties on Enceladus for Landing
The Planetary Science Journal, 2023 The prospect of landing on the surface of Enceladus comes with the question of whether the surface conditions permit selection and certification of one or more safe landing sites in an area of high science value.
