Meteoritics &Planetary Science, EarlyView.Abstract Terrestrial weathering alters the chemical and isotopic composition, and mineralogy, of meteorites; its effects on ordinary chondrites are well‐studied, but relatively little is known about the susceptibility of carbonaceous chondrites. We combined laboratory experiments, whereby Chwichiya 002 (C3‐ung find), Murchison (CM2 fall) and Kolang ...

Perihelion Asymmetry in the Water Production Rate of the Interstellar Object 3I/ATLAS
The Astrophysical Journal Letters3I/ATLAS is an interstellar object whose activity provides critical insights into its composition and origin. However, due to its orbital geometry, the object is too close to the Sun near perihelion to be observed from the ground, and space-based ...

Aqueous alteration in C2‐ung Bells through the analysis of carbonates – Does a CR origin ring true?
Meteoritics &Planetary Science, EarlyView.Abstract Bells is an ungrouped carbonaceous chondrite that has in recent years been proposed as a CR‐an. This link to CR chondrites has previously been identified through the analysis of anhydrous silicates, for example, oxygen isotopic compositions of olivine (Marrocchi et al., 2023).

Orbital and Absolute Magnitude Distribution of Hilda Population
The Astronomical JournalThe Hilda population of asteroids is located in a large orbital zone of long-term stability associated with the Jupiter J3/2 mean-motion resonance. They are a sister population of the Jupiter Trojans, since both of them are likely made up of objects ...

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

AGU Advances, Volume 7, Issue 3, June 2026.Abstract In Low Earth Orbit (LEO), atmospheric drag is the dominant source of trajectory prediction error below approximately 700 km altitude, primarily due to inaccuracies in thermospheric density models. This work presents a method for temporally deconvolving Energy Dissipation Rates (EDRs) to produce single‐satellite density estimates, which can be ...

Terrestrial Analogs to Titan for Geophysical Research
Reviews of Geophysics, Volume 64, Issue 2, June 2026.Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...
