From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

First Observation of Electron Rolling‐Pin Distribution in Jupiter's Magnetosphere

Geophysical Research Letters
The electron rolling‐pin distribution, showing electron pitch angles primarily at 0°, 90°, and 180°, has been widely studied in the Earth's magnetosphere, but has never been reported in other planetary environments.

A Machine Learning‐Based Model of Three‐Dimensional Ion Fluxes in the High‐Altitude Earth's Northern Cusp

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Magnetic reconnection at the dayside magnetopause is the primary pathway for transferring mass, momentum, and energy from the solar wind into the terrestrial magnetosphere. Previous studies have shown that the spatiotemporal dynamics of dayside magnetic reconnection can be inferred remotely from properties of Earth's cusps, specifically their ...

Observational Analysis on the Relationship Between Chorus Waves and MeV Microburst Electron Precipitation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Microbursts are thought to be a key contributor to radiation belt electron loss, with chorus waves considered a primary driver of this precipitation. However, the conditions under which chorus waves produce MeV electron loss remain poorly constrained.

Chorus Element Repetition: Roles of Energetic Electron Injection and Nonlinear Wave Growth

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Chorus waves are coherent whistler‐mode emissions in Earth’s magnetosphere and play a key role in the acceleration and loss of radiation belt electrons. Their spectra commonly consist of discrete and repetitive elements, yet the mechanism governing this repetition is not fully understood.

Transport of Mirror Mode Structures through Saturn’s Magnetopause Reconnection

The Astrophysical Journal
Magnetopause reconnection plays a significant role in transferring plasma and energy from the solar wind to planetary magnetospheres. Using a Cassini measurement, we reported a magnetopause reconnection at Saturn, identified by the Hall magnetic field ...

Substorm Effects on Chorus Emissions Modulated by ULF Waves

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Although cross‐scale wave‐particle interactions play a critical role in energy transfer in the magnetosphere, the influence of geomagnetic activity on the physical mechanisms involved remains unclear. In this study, we investigate this question by analyzing Van Allen Probes‐A observations of an event occurring on 25 July 2016.

Analysis of Ion Cyclotron Waves during Cassini’s Flybys of Enceladus

The Astrophysical Journal
Ion cyclotron waves (ICWs) are ubiquitous phenomena within Saturn’s magnetosphere, particularly in the vicinity of Enceladus. This study focuses on the Cassini spacecraft’s flyby data of Enceladus to investigate the spatial distribution and properties of

A summary of observational records on periodicities above the rotational period in the Jovian magnetosphere [PDF]

Annales Geophysicae, 2009
The Jovian magnetosphere is a very dynamic system. The plasma mass-loading from the moon Io and the fast planetary rotation lead to regular release of mass from the Jovian magnetosphere and to a change of the magnetic topology.
