10 Years of Mapping the Icy Saturnian Satellites
, 2014 The Cassini spacecraft started its tour through the Saturnian system in July 2004. The Imaging Science Subsystem onboard the orbiter consists of a high-resolution Narrow Angle Camera (NAC) with a focal length of 2000 mm and a Wide Angle Camera (WAC) with

Polarimetry of Saturnian satellite Enceladus [PDF]
Advances in Astronomy and Space Physics, 2015 We present results of polarimetric observations of Saturn's moon Enceladus carried out from April 14, 2010 to April 13, 2013 in WR spectral band (550-750 nm). We used 2.6-m telescope equipped with a one-channel photoelectric photometer-polarimeter (Crimean Astrophysical Observatory). The measurements were performed at phase angles ranging from 1.65° to

Cassini’s Determination of the Gravity Fields of the Saturnian Satellites
, 2007 The determination of the gravity fields of the Saturnian satellites is one of the main scientific goals and responsibilities of the Cassini Radio Science team.

ORIGIN OF THE CHAOTIC MOTION OF THE SATURNIAN SATELLITE ATLAS [PDF]
The Astronomical Journal, 2016 ABSTRACT We revisit the dynamics of Atlas. Using Cassini ISS astrometric observations spanning 2004 February to 2013 August, Cooper et al. found evidence that Atlas is currently perturbed by both a 54:53 corotation eccentricity resonance (CER) and a 54:53 Lindblad eccentricity resonance (LER) with Prometheus.

A survey of low-velocity collisional features in Saturn's F ring [PDF]
, 2014 Small (~50km scale), irregular features seen in Cassini images to be emanating from Saturn's F ring have been termed mini-jets by Attree et al. (2012). One particular mini-jet was tracked over half an orbital period, revealing its evolution with time and

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

ORIGIN OF THE DIFFERENT ARCHITECTURES OF THE JOVIAN AND SATURNIAN SATELLITE SYSTEMS [PDF]
The Astrophysical Journal, 2010 The Jovian regular satellite system mainly consists of four Galilean satellites that have similar masses and are trapped in mutual mean motion resonances except for the outer satellite, Callisto. On the other hand, the Saturnian regular satellite system has only one big icy body, Titan, and a population of much smaller icy moons.

Curtain-based Maps of Eruptive Activity in Enceladus’s South-polar Terrain at 15 Cassini Epochs
The Planetary Science JournalWe map surface eruptive activity in Cassini images of Enceladus’s south-polar terrain (SPT) at 15 epochs spanning late 2009 to late 2015 using a refined curtain approach derived from that of J. N. Spitale et al. (S2015).

Soft X‐Ray Emission From Saturn's Magnetosheath II: Solar Wind Driving
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract Saturn's magnetosphere is dominated by Enceladus‐sourced neutrals, which spread throughout the system into the magnetosheath. The neutrals can charge exchange with highly charged solar wind ions, causing soft X‐ray emission (<2 ${< } 2$ keV) upon de‐excitation of the ion.
