Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract We present high‐precision Ni stable isotope data for mesosiderites, eucrites, and diogenites to investigate the accretion and differentiation of asteroid 4 Vesta. Ni isotope variations in eucrites and diogenites are dominated by kinetic diffusion and chondritic contamination, rendering them unsuitable for reconstructing Vesta's primitive Ni ...

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.

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract The Martian magnetosheath acts as a conduit for mass and energy transfer between the upstream solar wind and its induced magnetosphere. However, our understanding of its global properties remains limited. Using 9 years of data from NASA's Mars Atmosphere and Volatile EvolutioN mission, we performed a quantitative statistical analysis to ...

Statistical Analysis of Multiple Bow Shock Crossings at Mars
Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract We conduct a statistical analysis of multiple bow shock (BS) crossings at Mars. Data from the magnetometer (MAG) and Solar Wind Ion Analyzer (SWIA) onboard the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft from its first 2 years in orbit is used to identify flapping events.

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.
