Topographical Features of the Lunar Surface Unveiled Through Spherical Geodesic Triangulation Analysis Method of DEM Roughness at Equal Spatial Scales

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract This study introduces an innovative method using equal spherical geodesic triangulation to uniformly sample the digital elevation model (DEM) of the lunar surface, ensuring an even distribution of elevation data. Utilizing spherical spline fitting, we have proposed new methods for calculating slope angles and aspects. An equilateral triangular

Tracking Deep Magma Migration Through Diffuse CO2 Degassing: Insights From Piton de la Fournaise Volcano (2013–2023)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Volcano monitoring requires identifying and distinguishing physico‐chemical processes at various depths within magma plumbing systems and their links to volcanic activity. Long‐term monitoring of deep magma reservoirs, extending down to tens of kilometers, is crucial even though signals from these depths are often altered or attenuated before ...

Thermal Evolution of the Sulfur‐Rich, Small Terrestrial Planetary Core as Inferred From the Experimental Study of the Fe‐S‐O‐H System

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract The cores of rocky planets, including the Earth, are believed to contain light elements such as silicon, oxygen, sulfur, hydrogen, and carbon. Amongst them, sulfur appears to be rich in the cores of small terrestrial bodies like Mars and Ganymede. To understand the evolution of sulfur‐rich cores in the presence of other light elements, we have

Were There Tides on Ancient Mars?

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Tides are a key component in the Earth system as they help regulate climate and sustain life. Mars very likely had a surface ocean around 4–3 billion years ago. The NASA Curiosity Rover and the CNSA Zhurong Rover were sent to Gale Crater and the Vastitas Borealis Formation (VBF) on Mars to explore the surface and search for evidence of the ...
