Abstract Recent publications in soil science have reopened discussions over how soil and soil science should be defined, reflecting productive tension between historical constructs and the evolving frontiers of the discipline. While new definitions offered over the past decade provide valuable perspectives, they inevitably rely on past conventions and ...

Meteoritic Evidence for Injection of Trans-Neptunian Objects into the Inner Solar System [PDF]
There is excellent evidence that a dynamical instability in the early solar system led to gravitational interactions between the giant planets and trans-Neptunian planetesimals.

The outer solar system extends beyond a heliocentric distance of 5 AU. It contains the giant planets and their systems (rings and satellites), the Kuiper belt, the comets (except those which approach episodically the inner solar system) and, at its outer

The Dynamic Inducing Magnetic Field Signal at Triton
Abstract Triton, Neptune's largest moon, is suspected of harboring a subsurface ocean. Detecting sub‐surface oceans requires measuring the ocean's induced magnetic field, typically exploiting common frequencies at which the field environment of the moon changes, in this case Triton's path through Neptune's magnetosphere.

Precise orbit determination and high-accuracy ephemeris calculation for Nereid are crucial for understanding the dynamical origin of its high-eccentricity orbit. This study adopts a refined dynamical model that incorporates the gravitational influence of

We propose that one of the largest known bioconstructions (the Monte Zenone bioherm) in the Southern Alps, northern Italy, and its growth on a tilted and drowned platform block of the Norian Dolomia Principale was controlled by hydrothermal dolomitisation from fault‐controlled fluids during the Late Triassic–Early Jurassic rifting phase. Dolomitisation

Rotational fission of trans-Neptunian objects: the case of Haumea [PDF]
We present several lines of evidence, based on different kinds of observations, and we conclude that it is likely that rotational fission has occurred for a fraction of the known trans-Neptunian objects (TNOs).

Autonomous control of a reconfigurable constellation of satellites on geostationary orbit with artificial potential fields [PDF]
This paper presents a method of controlling a constellation of small satellites in Geostationary Earth Orbit (GEO) such that the constellation is able to reconfigure - changing the angular position of its members relative to the Earth’s surface in order ...

Spectral Trends across the Rings and Inner Moons of Uranus and Neptune from JWST NIRCam Images
JWST NIRCam images provide low-resolution spectra of the rings and inner moons orbiting Uranus and Neptune. These data reveal systematic variations in spectral parameters like the strength of the strong OH absorption band around 3 μ m and the spectral ...

Ozone Production by Electron Irradiation of Regolith Ice: Laboratory Study for the Icy Moons
Abstract We irradiate fine‐grained regolith pure water ice in ultra high vacuum with 5keV $5\,\text{keV}$ and 10keV $10\,\text{keV}$ electrons to study the radiolysis of water ice. The ice regolith is designed to closely mimic the physical characteristics of the surfaces of the icy moons of the Solar System.
