Assessment of Callisto Gravity-field Determination Using the Inter-satellite Range-rate Link

open access: yesThe Astronomical Journal
China will launch the “Tianwen-IV” mission around 2030, focusing on the orbiting exploration of Jupiter and Callisto, a moon of Jupiter. As part of this ambitious mission, a main satellite will carry another satellite that will be released in the Jupiter

Pitch Angle Distributions of Energetic Electrons Near Ganymede: Galileo EPD Measurements

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Galileo flew‐by Ganymede six times between 1996 and 2000. The Energetic Particles Detector (EPD) performed energy resolved, directional electron measurements, and together with the magnetometer data, pitch angle distributions (PADs) could be derived.

Temporal Changes in Europa's Ice Shell Thickness: Insights From Models of Convection

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Europa is characterized by a thin ice Ih shell overlying a subsurface ocean and a large solid core. Estimates of the outer ice shell's thickness range from a few kilometers to several tens of kilometers, with strong implications for Europa's thermal and geological history.

Evidence of an Extended Alfvén Wing System at Enceladus: Cassini's Multi‐Instrument Observations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract We report in situ evidence for Enceladus' Alfvén wing system and its coupling with Saturn's ionosphere, based on multi‐instrument observations from the Cassini spacecraft. Analysis of 36 events, including 13 from non‐flyby paths, confirms the existence of a Main Alfvén Wing (MAW) current system generated at Enceladus, and associated Reflected ...

Ozone Production by Electron Irradiation of Regolith Ice: Laboratory Study for the Icy Moons

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract We irradiate fine‐grained regolith pure water ice in ultra high vacuum with 5keV $5\,\text{keV}$ and 10keV $10\,\text{keV}$ electrons to study the radiolysis of water ice. The ice regolith is designed to closely mimic the physical characteristics of the surfaces of the icy moons of the Solar System.

Sampling the volcanic plumes at Io: Impact speeds and shock conditions

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 2, Page 241-271, February 2026.
Abstract The desire to sample material from the interior of Io, by flying through its volcanic plumes, requires consideration of the flyby speed and the types of sample collection techniques that can be utilized. Low speed collection (1–2.5 km s−1) would require an orbit around Io itself, which is unlikely due to the accumulated radiation dose that ...

Comparison of manual, image-guided, and femtosecond laser-assisted marking techniques for toric intraocular lens alignment

open access: yesPhotodiagnosis and Photodynamic Therapy
Background: To compare the visual outcomes and the accuracy of three axial marking techniques for toric intraocular lenses (IOLs): manual marking, the CALLISTO eye image-guided system and femtosecond laser-assisted capsulotomy marking.

The Origin of Jupiter’s Obliquity

open access: yesThe Planetary Science Journal, 2023
The origin of the 3.°12 obliquity of Jupiter’s spin axis to its orbit normal is unknown. Improved estimates of Jupiter’s moment of inertia rule out a previously proposed explanation involving a resonance with the precession of the inclined orbit of ...
