Constraints on the Feasibility of Ferrovolcanism on Asteroid 16 Psyche

Journal of Geophysical Research: Planets, Volume 130, Issue 8, August 2025.
Abstract Asteroid 16 Psyche's surface appears to be highly metallic, but its bulk density suggests a silicate‐rich interior. Ferrovolcanism has been suggested to explain how a silicate‐rich body could develop a metallic surface. This requires trapping of light elements bearing iron‐rich metallic melt in a core solidifying from the outside inwards.

From Amino Acids to α‐Keto Acids via β‐Elimination and Transamination Initiates a Pathway to Prebiotic Reaction Networks

Angewandte Chemie, Volume 137, Issue 29, July 14, 2025.
A reaction starting from two amino acids, phosphoserine and Gly, reveals a pathway to the α‐keto acid building blocks pyruvate and glyoxylate, key components of a plausible early metabolic system. A one‐pot β‐elimination and transamination sequence also initiates a cascade of protometabolic transformations that provide crucial insights into the ...

Mineralogical and Chemical Mapping of Martian Meteorite SaU 008 Using Deep UV Raman and Fluorescence Spectroscopy on Earth and Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 8, August 2025.
Abstract The NASA Mars 2020 mission Perseverance rover carries a piece of Martian meteorite Sayh al Uhaymir (SaU) 008 as part of the calibration payload for the SHERLOC science instrument. We report SHERLOC observations of the SaU 008 flight piece over the first 1,000 sols of the mission and compare them to measurements done prior to launch, showing ...
