Unusual Enhancement in He(23S) Airglow Brightness Associated With Interplanetary Magnetic Field Northward Turnings During the 2025 New Year's Day Storm

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The upper thermosphere is important in the context of space weather, but continuous monitoring of the thermosphere at high latitudes remains limited despite its strong variations associated with geomagnetic activity. Orthohelium, He(23S), is found from the upper thermosphere to lower exosphere, and is a promising tracer of atmospheric dynamics.

Enhancement of Magnetic Flux Transferred to the Magnetotail Due to a Storm‐Time Kelvin‐Helmholtz Instability

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Along the flank magnetopause, magnetosheath flow interfaced with the relatively stationary magnetosphere produces strong flow shears, and the Kelvin‐Helmholtz instability (KHI) occurs. When the interplanetary magnetic field (IMF) is southward, anti‐parallel day‐side reconnection and KHI can interact, which may enhance the reconnection rate as ...

Analysis on the Turbulent Properties of Current Sheets in the Solar Wind

The Astrophysical Journal
The energy dissipation of solar wind turbulence, closely linked to solar wind heating, is a fundamental process in space physics. Previous research indicates that current sheets in the solar wind significantly influence both energy dissipation and ...

Instabilities Driven by Proton Temperature Anisotropy in the Presence of Alpha Particles: Implications for Proton-temperature-anisotropy Constraint in the Solar Wind

The Astrophysical Journal, 2023
In situ measurements reveal that proton temperature anisotropy is ubiquitous in the solar wind. Various plasma instabilities have been proposed to regulate the distribution of the proton temperature anisotropy in the solar wind; detailed constraint ...

Optimized Wavy Thermal Radiative Analysis of Electrochemically Ternary Hybrid Nanomaterials Affected by an Induced Magnetic Force: An ANN‐Based Levenberg–Marquardt Backpropagation Approach

Advanced Physics Research, Volume 5, Issue 10, October 2026.
This diagram illustrates the wavy flow configuration of the model in a Cartesian coordinate system. It represents the heat and mass transfer characteristics of ternary hybrid nanofluids over a vertically wavy surface in the presence of an induced magnetic field and double‐diffusive mixed convection.

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

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 ...

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

Space 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 ...

Ionospheric Scintillation Induced by Hot Flow Anomalies via Particle Precipitation

AGU Advances, Volume 7, Issue 7, October 2026.
Abstract Ionospheric scintillation disrupts trans‐ionospheric radio signals and represents significant challenges for critical communication and navigation systems. Here we document that hot flow anomalies (HFAs), transient disturbances formed near Earth's bow shock, can contribute to scintillation near the cusp.
