Origin of Late Noachian‐Early Hesperian Valley Networks on Mars: Insights From Landform Evolution and Ice Sheet Modeling

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Dendritic valley networks on Mars have been cited as evidence for a warm and wet Noachian Mars, permitting rainfall precipitation and surface runoff. However, the climatic conditions required to sustain rainfall on early Mars remain debated.

The seven ages of Fortran

open access: yesJournal of Computer Science and Technology, 2011
When IBM's John Backus first developed the Fortran programming language, back in 1957, he certainly never dreamt that it would become a world-wide success and still be going strong many years later.

Corona Clustering on Venus Hints at Mantle Dynamics

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Coronae are ring‐shaped volcanic features on the surface of Venus whose origins are not well understood. Coronae are absent from the lowest and highest topographic regions, as well as lows and highs in the Venusian geoid. How coronae form remains debated; one hypothesis suggests that diapirs uplift the crust, creating ring fractures; later ...

Capturing Spatiotemporal and Subgrid Variability in Global Land Surface Albedo Parameterization

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.
Abstract Accurate surface albedo parameterization is critical for modeling Earth's energy balance. Yet, many schemes rely on static look‐up tables or semi‐empirical formulations that fail to capture spatiotemporal variations and complex radiative interactions. This study develops a physics‐informed machine‐learning parameterization using 19 years (2003–
