Galilean Satellites: Anomalous Temperatures Disputed [PDF]

open access: yesScience, 1977
Anomalous averaged infrared brightness temperatures of the Galilean satellites of Jupiter reported by Gross (1975) are rejected as falsely conceived and lacking physical reality. It is argued that the calculations of equilibrium temperatures should be corrected, whereupon predictions would be in satisfactory agreement with observations, in conformity ...

Assessing the Detectability of Europa’s Seafloor Topography from Europa Clipper’s Gravity Data

open access: yesThe Planetary Science Journal, 2022
Due to its size and tidal heating, Europa may potentially possess active volcanism and hydrothermal circulation at its seafloor. The upcoming Europa Clipper mission provides the opportunity to obtain global gravity maps over a range of spatial scales, up

Cratering Rates on the Galilean Satellites [PDF]

open access: yesIcarus, 1998
We exploit recent theoretical advances toward the origin and orbital evolution of comets and asteroids to obtain revised estimates for cratering rates in the jovian system. We find that most, probably more than 90%, of the craters on the Galilean satellites are caused by the impact of Jupiter-family comets (JFCs).

Stratigraphy, Crater Size–Frequency Distribution, and Chronology of Selected Areas of Ganymede’s Light and Dark Terrains

open access: yesThe Planetary Science Journal, 2023
The stratigraphy of the largest natural satellite of our solar system, Ganymede, is investigated using available global mosaic (basemap) and high-resolution images. We are focusing on the reconstruction of the formation and tectonic evolution of selected

Experimental Validation of Cryobot Thermal Models for the Exploration of Ocean Worlds

open access: yesThe Planetary Science Journal, 2023
Accessing the potentially habitable subsurface waters of Ocean Worlds requires a robotic ice probe (or “cryobot”) to traverse tens of kilometers of ice with temperatures ranging from ∼100 to 273 K.

The Lense-Thirring effect in the Jovian system of the Galilean satellites and its measurability [PDF]

open access: yes, 2005
In this paper we investigate the possibility of measuring the post-Newtonian general relativistic gravitomagnetic Lense-Thirring effect in the Jovian system of its Galilean satellites Io, Europa, Ganymede and Callisto in view of recent developments in ...

Jupiter’s Early Luminosity May Have Driven off Io’s Initial Water Inventory

open access: yesThe Planetary Science Journal, 2023
After its formation, Jupiter was substantially more luminous than it is at the present day (10 ^4 times). Right after formation, the inner satellites Io and Europa would have received an order-of-magnitude larger incoming flux from Jupiter, than solar ...

Galilean satellite ephemerides E5 [PDF]

open access: yesAstronomy and Astrophysics Supplement Series, 1998
New ephemerides of Jupiter's Galilean satellites are produced from an analysis of CCD astrometric data, Voyager-mission optical navigation images, mutual event observations, photographic plates, and eclipse timing observations. The resulting parameters, for use in the galsat computer software, are in the B1950 frame for use by the Galileo space mission.

Thermal Properties of the Leading Hemisphere of Callisto Inferred from ALMA Observations

open access: yesThe Planetary Science Journal, 2023
We present a thermal observation of Callisto's leading hemisphere obtained using the Atacama Large Millimeter/submillimeter Array at 0.87 mm (343 GHz).
