Accumulation of Dust on a Surface and the Subsequent Formation of Compact Aggregate Piles

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Dust aggregation is a prominent topic in space physics, yet the accumulation of dust on surfaces in airless environments remains poorly understood. It is commonly assumed that, during the initial stages of dust deposition, particles spread uniformly to form a monolayer.

Corinto: A Young, Extensively Rayed Crater That Produced a Billion Secondaries on Mars

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Corinto crater is a fresh, 13.9 km diameter impact crater in Elysium Planitia that produced one of the most extensive systems of thermally distinct rays and secondary craters on Mars, extending up to ∼2,000 km and covering a nearly 180° arc. It is the youngest crater of its size on Mars and impacted between 0.1 and 2.5 Ma into Early Amazonian ...

The Boulder‐Rich Blocky Unit of the Western Jezero Upper Fan: Discriminating Olivine and Pyroxene Compositions and Constraining Provenance

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The boulder‐rich unit of the Upper Western Fan in Jezero crater, Mars is the youngest preserved unit of the fan stratigraphy. Understanding boulder compositions, distribution, and textures is critical for constraining their emplacement, provenance, and the depositional history of the Western fan.

Magnetic Properties of Martian Impact Basins Including the Effect of Mantle Excavation

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The weak magnetism of many impact basins on Mars has historically been interpreted as evidence of the martian dynamo's cessation before ∼4.0 Ga. However, expected magnetic properties of these impact basins are poorly known because basin formation exhumes and recrystallizes mantle material, which has not been sampled by martian meteorites ...

Dark‐Toned Halite‐Enriched Veins Above the Marker Band Record a Drying Environment in Gale Crater

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The Martian surface preserves evidence of a global climate transition from wetter to drier conditions, but the nature of the fluids involved in this evolution remains poorly constrained. In Gale crater, the clay‐sulfate transition and presence of evaporite mineral assemblages can provide insights into the properties of these fluids and the ...
