Formation of Asteroid (16) Psyche by a Giant Impact

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

The New Space Race Era: The Exogeoheritage Challenge and Its Conservation

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract The escalating pace of space exploration has ushered in a new era reminiscent of the space race of the 1960s. However, the discourse on exogeoconservation—the protection of geological heritage—now demands a prominent place in decision‐making processes.

Craters and Lunar Lua (Pits/Skylights) in Mare Tranquillitatis and Marius Hills Reveal Variations in Protolith Properties

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract We investigated the regolith parent rock (“protolith”) properties of Mare Tranquillitatis and Marius Hills on the Moon, utilizing lunar pit craters (“lua”) to contextualize observations of rock abundance and crater degradation. We discovered a significant difference in underlying materials: the region around the Tranquillitatis lua is ...

Simulations of Radiological Dose Quantities in Astronauts During Solar Energetic Particle Events Across Modern Space History

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract Solar Particle Events (SPEs) represent one of the most significant hazards to future crewed space missions. Accurate assessment of radiation doses received by astronauts during these events is essential for determining the shielding requirements in spacecraft and off‐planet shelter design.

Forecasting SEP Atmospheric and Space Radiation by Coupling UMASEP and NAIRAS Models

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract The Nowcast of Aerospace Ionizing RAdiation System (NAIRAS) model predicts the radiation environment from the Earth's surface to free‐space. The model output provides dosimetric and particle flux quantities required to assess the hazardous radiation impacts to human health and adverse effects on vehicle electronic systems.
