An Investigation of Libration Heating and the Thermal State of Enceladus's Ice Shell [PDF]

open access: yesIcarus, 114769 (2021), 2021
Tidal dissipation is thought to be responsible for the observed high heat loss on Enceladus. Forced librations can enhance tidal dissipation in the ice shell, but how such librations affect the thermal state of Enceladus has not been investigated. Here we investigate the heating effect of forced librations using the model of Van Hoolst et al.

ENCELADUS GEODETIC FRAMEWORK [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
The small (approximately 500 km in diameter) satellite Enceladus is moving near the equatorial plane and deep in the gravity field of its parent planet Saturn.

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.

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

Enceladus as a Potential Niche for Methanogens and Estimation of Its Biomass

open access: yesLife, 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 ...

Evidence that a novel type of satellite wake might exist in Saturn's E ring [PDF]

open access: yesPlanetary Science Journal 2 (2021) 127, 2021
Saturn's E ring consists of micron-sized particles launched from Enceladus by that moon's geological activity. A variety of small-scale structures in the E-ring's brightness have been attributed to tendrils of material recently launched from Enceladus.

Particle entrainment and rotating convection in Enceladus’ ocean

open access: yesCommunications 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 ...

Predicting the Effect of Surface Properties on Enceladus for Landing

open access: yesThe 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.

Low effective ultraviolet exposure ages for organics at the surface of Enceladus

open access: yesCommunications Earth & Environment, 2023
The saturnian moon Enceladus presents a remarkable opportunity in our solar system for searching for evidence of life, given its habitable ocean and plume that deposits organic-bearing ocean material onto the surface.

Investigating the porosity of Enceladus [PDF]

open access: yes, 2023
The interior of Enceladus, a medium sized icy moon of Saturn hosts hydrothermal activity and exhibits tidal heating and related geyser-like activity. There are major disagreements in the existing literature on the porosity of the interior, due to the different theoretical assumptions on which porosity related calculations were based.
