A LIBRATION MODEL FOR ENCELADUS BASED ON GEODETIC CONTROL POINT NETWORK ANALYSIS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
A new global control point network was derived for Enceladus, based on Cassini and Voyager-2 image data. Cassini images were taken from 2005 to 2014, for Voyager we have only one flyby in the middle of 1981.

Design and performance of low-energy orbits for the exploration of Enceladus [PDF]

open access: yesCommunications in Nonlinear Science and Numerical Simulation, Volume 90, 2020, 105393, ISSN 1007-5704, 2020
The icy moons are in the focus of the exploration plans of the leading space agencies because of the indications of water-based life and geological activity observed in a number of these objects. In particular, the presence of geyser-like jets of water near Enceladus' south pole has turned this moon of Saturn into a priority candidate to search for ...

Using Tidally‐Driven Elastic Strains to Infer Regional Variations in Crustal Thickness at Enceladus

open access: yesGeophysical Research Letters, 2023
Constraining the spatial variability of the thickness of the ice shell of Enceladus (i.e., the crust) is central to our understanding of the internal dynamics and evolution of this small Saturnian moon.

Comment on `Heating of Enceladus due to the dissipation of ocean tides' by R. Tyler [PDF]

open access: yesIcarus 350 (2020) 113934, 2020
Dissipation of ocean potential energy is proposed by Tyler (2020) as a new mechanism leading to possible high-power states for Enceladus. I show here that this process actually results from viscoelastic dissipation within the crust. For plausible values of Enceladus's ocean thickness, crustal dissipation can be computed with the standard approach of ...

Returning Samples From Enceladus for Life Detection

open access: yesFrontiers in Astronomy and Space Sciences, 2020
Evidence suggests that Saturn's icy moon Enceladus has a subsurface ocean that sources plumes of water vapor and ice vented to space from its south pole.

Spatial Distribution of Glycine and Aspartic Acid in Rapidly Frozen Brines Relevant to Enceladus

open access: yesThe Planetary Science Journal, 2023
Saturn’s moon Enceladus harbors a global, subsurface liquid ocean beneath an icy crust that actively erupts water jets from fissures in its south pole. Data returned from the Cassini mission have identified salts and organic matter within these ejected ...

Enceladus's measured physical libration requires a global subsurface ocean [PDF]

open access: yesIcarus 264, 37-47 (2016), 2015
Several planetary satellites apparently have subsurface seas that are of great interest for, among other reasons, their possible habitability. The geologically diverse Saturnian satellite Enceladus vigorously vents liquid water and vapor from fractures within a south polar depression and thus must have a liquid reservoir or active melting. However, the

A Recent Impact Origin of Saturn’s Rings and Mid-sized Moons

open access: yesThe Astrophysical Journal, 2023
We simulate the collision of precursor icy moons analogous to Dione and Rhea as a possible origin for Saturn’s remarkably young rings. Such an event could have been triggered a few hundred million years ago by resonant instabilities in a previous ...

Comparing Jupiter and Saturn: dimensionless input rates from plasma sources within the magnetosphere [PDF]

open access: yesAnnales Geophysicae, 2008
The quantitative significance for a planetary magnetosphere of plasma sources associated with a moon of the planet can be assessed only by expressing the plasma mass input rate in dimensionless form, as the ratio of the actual mass input to some ...

Blocks Size Frequency Distribution in the Enceladus Tiger Stripes Area: Implications on Their Formative Processes

open access: yesUniverse, 2021
We study the size frequency distribution of the blocks located in the deeply fractured, geologically active Enceladus South Polar Terrain with the aim to suggest their formative mechanisms.
