Different types of small volcanos on Venus [PDF]

One of the studies of volcanic activity on Venus is the comparison of that with the analogous volcanic activity on Earth. The preliminary report of such a comparison and description of a small cluster of small venusian volcanos is represented in detail ...

Experimental Hypervelocity Dust Impacts in Olivine—Multiscale Insights Into Microcrater Shock and Melting Effects From Coordinated SEM/TEM Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The flux of solar system meteoroids is dominated by objects less than 1 mm in diameter whose impact effects play a major role in the space weathering of airless body surfaces. These effects remain poorly characterized with respect to their dependence on the range of impact speeds for meteoroids across the inner solar system.

Topographic Relaxation of Complex Impact Craters in a Clathrate Crust on Titan

The Planetary Science Journal
Titan’s impact craters are significantly shallower than fresh craters on Ganymede, which are often used as templates for fresh craters on Titan. The presence of a clathrate crust on Titan, which would insulate the ice shell and maintain warmer ice near ...

Exploring Terrestrial Lava Tubes as Martian Analogs (I): Multi‐Analytical Study of Mineralization Processes in Cueva del Vidrio, La Palma (Canary Islands)

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The study of terrestrial lava tubes is essential for understanding geological processes occurring during volcanic activity on other planetary bodies, such as Mars. These processes lead to the formation of minerals analogous to those found on other planets.

The Constraint of Crewed Mars Missions Based on Current Radiation Dose Measurements

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Crewed missions to Mars will be a milestone of future space exploration programs. However, the absence of Earth's magnetic field leaves astronauts directly exposed to unattenuated energetic particles in deep space, primarily galactic cosmic rays (GCRs), resulting in significantly higher radiation levels and enhanced health risks. Understanding

Dome craters on Ganymede [PDF]

Voyager observations reveal impact craters on Ganymede that are characterized by the presence of broad, high albedo, topographic domes situated within a central pit. Fifty-seven craters with central domes were identified in images covering approx. 50% of

Change the world farm by farm: The moral care of audit and the paradox of animal welfare inspection in Europe Changer le monde, ferme par ferme : le soin moral de l'audit et le paradoxe des contrôles du bien‐être animal en Europe

Journal of the Royal Anthropological Institute, Volume 32, Issue 1, Page 55-74, March 2026.
In European animal welfare inspection on farms and at slaughter, inspectors encounter moral challenges that reveal the paradox at the heart of animal welfare. Against the harsh realities of industrial agriculture, not only are their idealized notions of animal wellbeing unrealizable, but inspectors are instrumental in perpetuating standards of welfare ...

Electron petrography of silica polymorphs associated with pseudotachylite, Vredefort structure, South Africa [PDF]

High-pressure silica polymorphs (coesite and stishovite) were described from the Vredefort structure in association with pseudotachylite veinlets. In addition to the fundamental significance of the polymorphs to genetic interpretations of the structure ...

RioM‐1: A New Calcite Reference Material for U‐Pb LA‐ICP‐MS Geochronology

Geostandards and Geoanalytical Research, Volume 50, Issue 1, Page 181-199, March 2026.
Key Points RioM‐1 calcite was characterised for trace elements, U‐Pb geochronology, Sr and O isotopes using ID‐TIMS, LA‐ICP‐MS and SIMS. U‐Pb dates from ID‐TIMS and LA‐ICP‐MS across several independent laboratories returned identical results within uncertainty.

MEVTV study: Early tectonic evolution of Mars: Crustal dichotomy to Valles Marineris [PDF]

Several fundamental problems were addressed in the early impact, tectonic, and volcanic evolution of the martian lithosphere: (1) origin and evolution of the fundamental crustal dichotomy, including development of the highland/lowland transition zone; (2)
