ENCELADUS GEODETIC FRAMEWORK [PDF]
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.

Librational response of Enceladus [PDF]
Physical librations could significantly contribute to Enceladus' geophysics through their influence on tidal stress. Therefore it is important to determine their behavior and the present paper is devoted to estimating Enceladus' libration in longitude. In a rotational model of Enceladus with no global ocean, we introduce the main perturbative terms of ...

The obliquity of Enceladus [PDF]
The extraordinary activity at Enceladus' warm south pole indicates the presence of an internal global or local reservoir of liquid water beneath the surface. While Tyler (2009, 2011) has suggested that the geological activity and the large heat flow of Enceladus could result from tidal heating triggered by a large obliquity of at least 0.05°-0.1 ...

The Tides of Enceladus' Porous Core [PDF]
AbstractThe inferred density of Enceladus' core, together with evidence of hydrothermal activity within the moon, suggests that the core is porous. Tidal dissipation in an unconsolidated core has been proposed as the main source of Enceladus' geological activity.

Enceladus exhibits some remarkable phenomena, including water geysers spraying through surface cracks, a global ice shell that is librating atop an ocean, a large luminosity, and rapid outward orbital migration.

A Recipe for the Geophysical Exploration of Enceladus
Abstract Orbital geophysical investigations of Enceladus are critical to understanding its energy budget. In this paper, we identified key science questions for the geophysical exploration of Enceladus, answering which would support future assessment of Enceladus’ astrobiological potential.

From early Earth to Enceladus—mineral electrochemistry could drive organic synthesis [PDF]
Hydrothermal systems in the ocean can behave like fuel cells when minerals connect reduced vent fluids to oxidized seawater, sustaining electrical potentials that drive reactivity.

The topography of Enceladus [PDF]
The surface of Enceladus modeled so far has relief of not more than ~2 km both at small (10 km) and larger (100 km) scales. This suggests that the lithosphere has been at most only a few kilometers thick over its history. A stereo-derived height model of the region between Enceladus’ leading side and the Saturnfacing side (Fig.

The Bolometric Bond Albedo of Enceladus [PDF]
The bolometric Bond albedo is a fundamental parameter of planets and moons. Here, combined observations from the Cassini spacecraft and the Hubble Space Telescope are used to determine the bolometric Bond albedo of Enceladus.

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