Surface ages of mid-size saturnian satellites [PDF]

Icarus, 2015
The observations of the surfaces of the mid sized Saturnian satellites made by Cassini Huygens mission have shown a variety of features that allows study of the processes that took place and are taking place on those worlds. Research of the Saturnian satellite surfaces has clear implications for Saturn history and surroundings.

Saturnian Irregular Satellites as a Probe of Kuiper Belt Surface Evolution [PDF]

The Planetary Science Journal
We present the JWST NIRSpec PRISM 0.7–5.3 μ m spectra of Albiorix and Siarnaq and the NIRSpec G235H/G395M 1.7–5.3 μ m spectra of Phoebe, the three largest Saturnian irregular satellites.

Ice-Ocean Exchange Processes in the Jovian and Saturnian Satellites

Space Science Reviews, 2020
A growing number of satellites in the outer solar system likely have global oceans beneath their outer icy shells. While the presence of liquid water makes these ocean worlds compelling astrobiological targets, the exchange of heat and materials between the deep interior and the surface also plays a critical role in promoting habitable environments. In

Cratering and age of the small Saturnian satellites [PDF]

Astronomy & Astrophysics, 2019
Context. The small (≤135 km mean radius) satellites of Saturn are closely related to its rings and together they constitute a complex dynamical system where formation and destruction mechanisms compete against each other. The Cassini-Huygens mission provided high-resolution images of the surfaces of these satellites and therefore allowed for the ...

Astrometric Reduction of Saturnian Satellites with Cassini-ISS Images Degraded by Trailed Stars [PDF]

Research in Astronomy and Astrophysics, 2023
The Imaging Science Subsystem (ISS) mounted on the Cassini spacecraft has taken a lot of images, which provides an important source of high-precision astrometry of some planets and satellites.

UV-Induced Formation of Ice XI Observed Using an Ultra-High Vacuum Cryogenic Transmission Electron Microscope and its Implications for Planetary Science [PDF]

Frontiers in Chemistry, 2021
The occurrence of hydrogen atom-ordered form of ice Ih, ice XI, in the outer Solar System has been discussed based on laboratory experiments because its ferroelectricity influences the physical processes in the outer Solar System.

Positional measuring procedure and CCD observations for Saturnian satellites [PDF]

Astronomy & Astrophysics, 2002
A positional measuring procedure for the eight major satellites of Saturn (Mimas, Enceladus, Tethys, Dione, Rhea, Titan, Hyperion and Iapetus) is developed. Using this procedure, 199 frames of CCD images, obtained with the 1-meter telescope at the Yunnan Observatory from 1996-2000, are measured.

Shallow normal fault slopes on Saturnian icy satellites [PDF]

Journal of Geophysical Research: Planets, 2015
AbstractFault dips are a function of the coefficient of internal friction, μi, of the lithospheric material. Laboratory deformation experiments of H2O ice at conditions applicable to icy bodies yield 0 ≤ μi ≤ 0.55 such that normal faults dip between 45° and 59°.

Astrometric observations of inner Saturnian satellites [PDF]

Astronomy and Astrophysics, 2001
This paper presents observations of four inner Saturnian satellites (SX = Janus, SXI = Epimetheus, SXVI = Prometheus and SXVII = Pandora) made in August and November 1995 during the Earth and Sun crossings of Saturn's ring plane, respectively. The August 1995 data combine data taken with the Adonis optics system mounted on the ESO 3.6-m telescope at La
