Electron Acceleration and Zebra Stripe Formation in Saturn's Radiation Belts
Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.Abstract This study uses the Versatile Electron Radiation Belt code to model Saturn's radiation belt environment, investigating electron acceleration, loss, and transport mechanisms. The simulations consider various physical processes, including convection particularly driven by a Volland‐Stern (VS) electric field, radial diffusion, collisional energy ...

Solar Cycle and Seasonal Dependences of Field‐Aligned Currents
Space Weather, Volume 23, Issue 5, May 2025.Abstract Enhancements of Birkeland field‐aligned currents (FACs) have been reported during magnetospheric substorms and geomagnetic storms. While FACs related to geomagnetic disturbances have been extensively studied, the long‐term variations of FACs remain less explored.

An overview of the petrography and petrology of particles from aggregate sample from asteroid Bennu
Meteoritics &Planetary Science, Volume 60, Issue 5, Page 979-996, May 2025.Abstract The OSIRIS‐REx mission returned a sample of regolith from the carbonaceous asteroid Bennu in September 2023. We present preliminary in situ investigations of the petrology and petrography of selected particles ranging in size from 0.5 to 3 mm.

Detection of Low‐Altitude Cislunar Dust With the Lunar Occultation Archive
Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract It is believed that dust formations above the lunar surface, manifested via sunlight scattering and detected in‐situ, are of too low density to pose threats to lunar missions. However, occasionally prolonged fading/kindling of the immersing/emerging stars near the lunar limb indicates much denser low‐altitude dust clouds.

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Traveling ionospheric disturbances (TIDs) driven by a large number of internal and external sources are detectable with dense networks of ground‐based Global Navigation Satellite System (GNSS) receivers' measurements of total electron content (TEC).

Numerical Simulations for Optimizing Small Satellite Constellations for TGF Studies
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 8, 28 April 2025.Abstract The detection of Terrestrial Gamma ray Flashes (TGFs) from space is mostly made by astrophysics satellites, which only provide single‐point measurements. Future TGF missions could consist in performing simultaneous detection by a detector array in space.
