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

open access: yesJournal 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

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

open access: yesJournal 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 ...

Global Energy Circulation During a Solar Wind Density Pulse

open access: yesSpace Weather
We study the propagation and impacts of a strong density pulse through the magnetosphere during 11:40–12:00 UT near the peak of a geomagnetic storm on 3 February 2022. Using the Space Weather Modeling Framework Geospace global simulation, we show how the

Dynamic Evolution of a Storm‐Time “Super‐EPB” Event Over China on the Magnetically Disturbed Night of 01 December 2023

open access: yesSpace Weather, Volume 24, Issue 10, October 2026.
Abstract This paper investigates the dynamic evolution of a storm‐time “Super‐EPB” event over China on 1 December 2023 (Kp ≤ 7, SYM/H ≥ −130 nT) using multi‐instrument observations. Occurring near sunset as the IMF‐Bz abruptly turned southward, with auroral extension to midlatitudes, the “Super‐EPB” extended to 40°N with an apex height of ∼2,460 km ...

Global Three‐Dimensional Simulation of Magnetospheric Dynamics During the Extreme Geomagnetic Storm of 10–11 May 2024

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study presents a high‐resolution three‐dimensional global magnetohydrodynamic (MHD) simulation of the historic geomagnetic storm of 10–11 May 2024, using observational data for the ACE solar wind input. This extreme event was characterized by intense solar wind dynamic pressure (∼50 nPa) and exceptionally strong interplanetary magnetic ...

Statistical Analysis of the Equatorward UV Auroral Emissions of the Jovian Southern Hemisphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study presents a comprehensive statistical analysis of Jupiter's southern UV auroral emissions, with a focus on the secondary oval and equatorward injection signatures. Utilizing Hubble Space Telescope (HST) data, the frequency, location, and intensity of these auroral features are systematically evaluated, considering their variation ...

Earthward O+ Injections in the Plasma Sheet Boundary Layer During Geomagnetic Storms

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract During geomagnetic storms, energetic ions are injected from the Earth's magnetotail along the plasma sheet boundary layer (PSBL). Owing to its off‐equatorial inclined orbit, the Arase satellite is in a prime position to observe these injections in the PSBL on the nightside at the apogee.
