A Panspermia Origin for Venus Cloud Life
Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Decades of study have hinted at the astrobiological potential of Venus's cloud layers. This potential is often cast as stemming from the idea that the Venusian surface was clement in the past. As the climate changed, life then remained in, or perhaps evolved and migrated to, the last habitable niche: the altitudes above ∼50 km with Earth‐like ...

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract The excess abundance of highly siderophile elements (HSEs), as inferred for the terrestrial planets and the Moon, is thought to record a “late veneer” of impacts after the giant impact phase of planet formation. Estimates for total mass accretion during this period typically assume all HSEs delivered remain entrained in the mantle.

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract The 2028 ESA/NASA Rosalind Franklin Mission (RFM) will search for signs of past and present life in the shallow subsurface of Mars. It is crucial to understand how minerals and any biosignatures uncovered during these sampling activities might change and be identified under today's Martian conditions.

Evaluating Seismic Ambient Noise Techniques for Imaging Lava Tubes on the Moon
Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Detecting and characterizing lava tubes is a key objective of upcoming lunar missions. While evidence for their presence exists, their precise dimensions and depths remain uncertain. This study evaluates the potential of seismic ambient noise methods, such as seismic interferometry, H/V spectral ratios, distributed acoustic sensing (DAS), and ...

Rocket Exhaust Derived Surface Water Migration at Lunar Landing Sites
Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Volatiles, especially water, are at the center of modern lunar explorations. They have various sources, including volcanism, asteroid/comet impacts, and Earth/solar wind implantations. However, due to the lack of in situ data, it has not been widely recognized that artificial activities, especially rocket exhaust, could significantly impact ...
