Development of a mass spectrometer system for the measurement of inert gases in meteorites [PDF]

open access: yes, 1983
The study of the inert gases in meteorites has provided many clues as to the origin and evolution of the solar system. Particularly crucial and complex are the gases krypton and xenon.

Olivine‐Ahrensite Phase Relations in the Mg2SiO4‐Fe2SiO4 System as a Function of Temperature

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Olivine and ahrensite are the primary components of the interiors of Fe‐rich terrestrial planets and meteorites, making their phase relations crucial for planetary science. Moreover, their phase relations can be used for calibrating large‐volume high‐pressure devices such as multi‐anvil apparatus.

Emergent Chemical Reactivity and Complexity of RNA Condensates

open access: yesAngewandte Chemie, Volume 137, Issue 52, December 22, 2025.
RNA condensates capable of substrate enrichment and catalysis modulate their environment. Could this start a catalytic selection loop or evolution? Abstract The RNA world hypothesis posits the existence of life‐like assemblies that consisted mostly of RNA.

Stratigraphy of Carbonate‐Bearing Rocks at the Margin of Jezero Crater, Mars: Evidence for Shoreline Processes?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Martian carbonate‐bearing rocks are compelling targets for exploration because they preserve detailed records of past aqueous processes, climate, and habitability. The Margin unit in Jezero crater is a distinct olivine‐ and carbonate‐bearing unit stratigraphically underlying the western fan, lining the inner margin of the western crater rim ...

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.
