The Challenge of Icy Sample Return Begins With Artemis

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Throughout the Solar System, volatiles are found as solid ices. Returning ices to Earth for scientific analysis is critical to understanding the formation of a Solar System that bears life. This challenge begins with the Artemis missions to the lunar south polar region, where the coldest lunar regolith is enriched in H2O and other ices—systems

Freeze‐Thaw Cycling Accelerated Olivine Weathering and Water Sequestration on Icy Mars

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Geological evidence and paleoclimate models suggest that freeze‐thaw (FT) cycling has played a pivotal role in shaping the Martian surface composition throughout geological time. Here we show the experimental investigation of the sulfuric acid weathering of olivine under simulated FT conditions (193–293 K).

Lithospheric Mantle Heterogeneity Drives Delayed Magmatism and Wide Continent‐Ocean Transitions in Rifted Margins

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The formation of wide, magma‐starved continent–ocean transition (COT) zones remains incompletely understood. We use 2‐D thermo‐mechanical numerical experiments, coupling hydrous mantle melting with parameterized crustal accretion, to explore controls on magmatic lag: the delay between continental crustal break‐up and steady oceanic crustal ...
