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 ...

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 ...

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.

The Carbonate Geochemistry of Enceladus' Ocean

open access: yesGeophysical Research Letters, 2020
The plume composition at Enceladus contains clues about conditions and processes in the interior. We present new geochemical interpretations of Cassini mass spectrometry data from the plume gas and salt‐rich ice grains.

Photoelectrons in the Enceladus plume [PDF]

open access: yes, 2013
The plume of Enceladus is a remarkable plasma environment containing several charged particle species. These include cold magnetospheric electrons, negative and positive water clusters, charged nanograins, and magnetospheric photoelectrons produced from ...

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.

Method for detecting and quantitating capture of organic molecules in hypervelocity impacts

open access: yesMethodsX, 2021
Enceladus is a prime candidate in the solar system for in-depth astrobiological studies searching for habitability and life because it has a liquid water ocean with significant organic content and ongoing cryovolcanic activity. The presence of ice plumes

Alien Carousel: In Situ life detection on icy moons with a single-actuator holographic microfluidic platform

open access: yesFrontiers in Astronomy and Space Sciences
Enceladus, one of Saturn’s moons, is considered one of the most promising places in the solar system to find life. The Cassini mission discovered organic-rich water plumes from Enceladus’s subsurface ocean, prompting new lander mission planning.

A Recipe for Geophysical Exploration of Enceladus

open access: yes, 2020
Orbital geophysical investigations of Enceladus are critical to understand its energy balance. Mapping Enceladus' gravity field, improving the accuracy of the physical libration amplitude, and measuring Enceladus' tidal response would provide critical ...
