Planetary Exploration 3.0: A Roadmap for Software-Defined, Radically Adaptive Space Systems

The surface and subsurface of worlds beyond Mars remain largely unexplored. Yet these worlds hold keys to fundamental questions in planetary science – from potentially habitable subsurface oceans on icy […]

ALMA Reveals Interstellar Comet 3I/ATLAS Formed in a Far Colder World Than Our Own

New observations from the Atacama Large Millimeter/submillimeter Array (ALMA) have yielded the first-ever measurement of deuterated water — also known as semi-heavy water — in an interstellar object. The discovery […]

Secular Light Curve of Exocomet 3I/ATLAS, and its Location on a Comet Evolutionary Diagram

In this work we will create the Secular Light Curve (SLC) of exocomet 3I/ATLAS, using the SLC-Methodology (Ferrin 2010-2023). The SLCs give a throve of new information and allow the […]

Analysing The Sample Preparation Process In Meteorites And Its Impact On The Pretreatment Of Returned Samples To Earth

The study of meteorites is important for planetary sciences because, among other things, it can provide information about the geochemical composition of their celestial body of origin. Often, subsample preparation […]

Distribution Of Extraterrestrial Nucleobases, Other N-heterocycles, And Their Precursors In A Sample From Asteroid Bennu

The recent discovery of all five canonical nucleobases in samples from Bennu provides compelling evidence that some of life’s ingredients were synthesized abiotically in the parent body of this asteroid […]

The Zhamanshin Impact Event: Potential Implications for Environmental Responses and Biological Linkages on Earth and Beyond

At least one large-body (diameter > 1.1 km) hypervelocity cratering event occurred during ~ 0.8-0.90 Ma (Zhamanshin, Kazakhstan) in the Middle Pleistocene Transition period.
