Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.Abstract We present a comprehensive study of a new Martian meteorite, Northwest Africa (NWA) 16788, found in the Sahara Desert in July 2023. This specimen constitutes the largest known individual meteorite of Martian origin, with a total weight of ⁓25 kg. A detailed mineralogical and geochemical investigation identifies NWA 16788 as an enriched olivine

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.Abstract The internal structures of asteroids are estimated iteratively via a classic gravity‐field‐inversed method on the ground computer in the post‐mission phase due to a large amount of gravity data. This paper develops a flight‐information‐perceived approach that has a superb capacity for constructing the interiors of a differentiated celestial ...

Fluvial valleys on Martian volcanoes [PDF]
Channels and valleys were known on the Martian volcanoes since their discovery by the Mariner 9 mission. Their analysis has generally centered on interpretation of possible origins by fluvial, lava, or viscous flows.

Examining the Quantification Capability of Automated Mineralogy System: A Machine Learning Approach
Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.Abstract Automated mineralogy (AM) systems are a novel platform for material characterization. By analyzing the X‐rays generated from sample–electron interactions, these systems can rapidly and automatically provide mineralogical and textural descriptions of a sample.

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.Abstract We study the dynamical and thermal roles of internal gravity waves generated in the troposphere and above using the Coupled Middle Atmosphere Thermosphere‐2 General Circulation Model. This model incorporates the whole atmosphere nonlinear spectral gravity wave parameterization and its extension to include non‐tropospheric sources. We conducted

Physiological and technological considerations for Mars mission extravehicular activity [PDF]
The nature of the suit is a function of the needs of human physiology, the ambient environment outside the suit, and the type of activity to be accomplished while in the suit.
