Near‐Earth Cosmic Ray Modulation Index ϕ and Neutron Monitor Cutoff Rigidities at Hourly Cadence: Toward an Improved Monitoring of Solar‐Terrestrial Radiation Environment, Space Weather, and Space Climate

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic rays (CRs) are energetic particles originating from galactic and extragalactic sources. When arriving into the solar system and the Sun's heliosphere, they are diverted and modulated by the magnetic activity of the Sun. This modulation can be quantified by the modulation parameter ϕ $\phi $ determined with the Force‐field approximation (

Effect of Lunar Rotation on Antipodal Ejecta Deposition

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The Moon's crust exhibits strong magnetic anomalies that likely record ancient magnetic fields produced by a core dynamo. Lunar materials have low magnetic susceptibility, but impactor material with high susceptibility may record the Moon's ancient dynamo. Some magnetic anomalies are antipodal to lunar basins and it is hypothesized that impact

Topographic knowledge-aware network for automatic small-scale impact crater detection from lunar digital elevation models

International Journal of Applied Earth Observations and Geoinformation
Impact craters represent the most prevalent and prominent topographical features on the surfaces of planets. They provide crucial insights into the internal and surface-level geological activities of planets but are difficult to identify from digital ...

Coupling Seismic, Gravity and Magnetic Surveys for the Investigation of Planetary Lava Tubes: A Terrestrial Analog Case Study in Lanzarote (Spain)

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Lava tubes are subsurface volcanic conduits formed during effusive basaltic eruptions and are considered key targets for planetary exploration. Orbital remote sensing on the Moon and Mars has identified numerous collapse pits interpreted as possible surface expressions of underlying lava tube systems. However, the limited resolution of current

Characteristics of Lunar Surface Electrons Inferred From THEMIS‐ARTEMIS Observations: 2. Photoelectrons

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The lunar surface charging is controlled mainly by the balance of electron currents near the surface. One of the main electron currents is the photocurrent on the dayside, comprised of photoelectrons produced by solar photons ionizing the lunar surface.

Tidal and Rainfall Controls of CH4 Fluxes in a Southern Moreton Bay Mangrove‐Saltmarsh

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract Coastal wetlands play a crucial role in global carbon dynamics, acting as carbon dioxide (CO2) sinks while also emitting methane (CH4), a potent greenhouse gas. This study investigates CH4 fluxes over a six‐month period in a sub‐tropical coastal mangrove‐saltmarsh wetland in southern Moreton Bay, Queensland, Australia, using eddy covariance ...

Mission Design and Early Navigation Operations for the Lunar Trailblazer Mission

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Lunar Trailblazer is a smallsat mission launched on 27 February 2025 as a secondary payload with the Intuitive Machines IM‐2 mission. After insertion into a near‐polar circular orbit around the Moon, the mission's goal was to search and characterize lunar water, primarily looking for ice in permanently shadowed craters and water bound in ...

Formation of Compact Aggregate Piles on a Surface Through Dissipation of Kinetic Energy Associated With Horizontal Motion

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Accumulation of dust on the Lunar and Martian surfaces plays a critical role in both surface evolution and human exploration efforts, limiting equipment lifetimes and obscuring optical surfaces. Yet, the underlying physics of surface soiling is still poorly understood.
