Magnetic Reconnection as a Potential Trigger for Magnetotail Flapping at Mars: Insights From MAVEN and Tianwen‐1 Observations

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Magnetotail current sheet (CS) flapping is a universal plasma phenomenon observed at multiple planets, yet its triggering mechanisms remain poorly understood outside of Earth. At Mars, single‐spacecraft observations have also reported tail flapping, but the processes responsible for its onset have never been identified.

Magnetosphere of Mars at Almost Radial Interplanetary Magnetic Field

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract We have studied the structure of the Martian magnetosphere under conditions of an almost radial interplanetary magnetic field (IMF). Under such conditions, the currents driven by the motional electric field −1cVsw×BIMF ${-}\frac{1}{c}{\mathbf{V}}_{sw}\times {\mathbf{B}}_{\mathit{IMF}}$ are expected to be strongly reduced, and the induced ...

Investigation on the Coherent Component of SHARAD Surface Echo and Surface Roughness: Scaling Behavior and Influence of Hurst Exponent

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The radar surface echo can be separated into coherent and incoherent components by statistical approaches, and the coherent component can be described by a backscattering model related to the RMS height. According to backscattering models for fractal surfaces, the coherent power in decibels decreases with RMS height on a scale independent of ...

Three-dimensional Particle-in-cell Simulations of the Solar Wind Interaction with Asteroid 2016 HO3

The Astrophysical Journal, 2023
The recently discovered asteroid 2016 HO _3 is the most stable quasi-satellite of our Earth. Several missions to 2016 HO _3 have been proposed, including the Tianwen-2 mission of China.

Simulation Analysis on Influential Factors of the Anchoring Force of Claw‐Spine Attachment Device

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
Asteroids have the characteristics of weak gravity, unknown surface topography and physical properties, and low cohesion of asteroid rocks, which make long‐term attachment to an asteroid challenging. Considering these characteristics, a claw‐spine attachment device was designed, and the effect of anchoring force generation and structural optimization ...

Plasma Acceleration by Magnetic Tension Forces in the Martian Magnetotail: MAVEN Observations

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The Martian magnetotail is a dynamic region where several processes contribute to plasma acceleration. Here, we analyze ∼5 ${\sim} 5$ years of Mars Atmosphere and Volatile EvolutioN (MAVEN) data to evaluate the role of magnetic tension forces in driving plasma acceleration within current sheets in the tail. Based on magnetic field measurements,

Direct Observations of Acceleration of Planetary Ions From Mars' Ionosphere Through Magnetic Reconnection When IMF Rotates

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Mars lacks an intrinsic global magnetic field but possesses crustal magnetic anomalies and an atmosphere. Mars' ionosphere, resulted from interactions between Mars' atmosphere and solar radiation, directly interacts with solar wind and interplanetary magnetic field (IMF). However, the mechanisms governing ion acceleration and escape from Mars'
