Studying the Inner Heliosphere Using Radio Signals Transmitted From Spacecraft Orbiting Mars
Space Weather, Volume 23, Issue 5, May 2025.Abstract In this campaign, we used very long baseline interferometry (VLBI) radio telescopes to track the carrier radio signal transmitted from spacecraft orbiting Mars during the Mars solar conjunction. The campaign extended from September 6th $6\text{th}$ to November 6th $6\text{th}$ 2021 and targeted the Mars Express (MEX) and Tianwen‐1 (TIW ...

Infiltration Dynamics on Early Mars: Geomorphic, Climatic, and Water Storage Implications
Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract On early Mars, the integration of surface, groundwater, and climate systems into an integrated hydrological system remains poorly understood. The partitioning of precipitation, between surface and groundwater via infiltration, controls the Martian aquifer recharge rates and, subsequently, surface erosion processes.

Formula for the Chandler Period (Free Wobble of Planetary Bodies)
Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract If the rotational equilibrium of a planetary body is disturbed, the rotation pole responds with a cyclical motion. The duration of one cycle is referred to as the Chandler period, and, when viewed from space, the body wobbles. Because planets are not rigid, the wobble period differs from the Euler period by the factor 1−kX/kf $\left(1-{k}_ ...

Origin of Martian Moons from Binary Asteroid Dissociation [PDF]
arXiv, 2009 The origin of the Martian moons Deimos and Phobos is controversial. One hypothesis for their origin is that they are captured asteroids, but the mechanism requires an extremely dense martian atmosphere, and the mechanism by which an asteroid in solar orbit could shed sufficient orbital energy to be captured into Mars orbit has not been well elucidated.

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Mars lacks an intrinsic dipolar magnetic field but possesses strong crustal magnetic fields scattered across its surface. There has been an ongoing debate about how these crustal fields influence the bow shock, the outermost plasma boundary of the Martian space environment.

Behaviors of Martian CO2-driven dry climate system and conditions for atmospheric collapses [PDF]
arXivThe present Martian climate is characterized by a cold and dry environment with a thin atmosphere of carbon dioxides (CO2). In such conditions, the planetary climate and habitability are determined by the distribution of CO2 between exchangeable reservoirs, that is the atmosphere, ice caps, and regolith.

Efficiency of Thermoremanent Magnetization Acquisition in Vortex‐State Particle Assemblies
Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Magmatic rocks record ambient magnetic fields during cooling, preserving them for billions of years through thermoremanent magnetization (TRM). TRM accuracy depends on particle size, shape, magnetic properties, and the number of particles available to record the field.
