Accurate 3D fireball trajectory and orbit calculation using the 3D-FireTOC automatic Python code

, 2021
The disruption of asteroids and comets produces cm-sized meteoroids that end up impacting the Earth's atmosphere and producing bright fireballs that might have associated shock waves or, in geometrically-favorable occasions excavate craters that put them

Impact‐diagnostic criteria for use in confirming a meteorite impact origin of terrestrial geological structures: Recommendations by the Impact Cratering Committee of the Meteoritical Society

Meteoritics &Planetary Science, EarlyView.
Abstract The framework of the Impact Cratering Committee (ICC) of the Meteoritical Society was approved in 2020, with the first committee members appointed in 2023. The ICC has a mandate to (1) approve, maintain, and update a database of confirmed terrestrial meteorite impact structures, (2) define and regularly update the criteria used for ...

Accretion of Meteoric Organic Matter at the Surface of Mars and Potential Production of Methane by Ultraviolet Radiation

The Planetary Science Journal
In this study, a comprehensive model of the meteoric organic cycle on Mars for the current geological period is developed, which characterizes the ablation of exogenous organic matter in the upper atmosphere, the accretion of intact carbon at the surface,

Achondrites in meteor data: Spectra, dynamics, and physical properties of candidate aubrite and eucrite impactors

Astronomy & Astrophysics
Meteor spectroscopy presents new opportunities for investigating the diversity of small Solar System bodies and capturing the real distribution of present material types. In this work, we analyzed a sample of 180 higher-resolution meteor spectra from the

Stardust Mine: A 2024 gabbroic shergottite from Arizona, USA

Meteoritics &Planetary Science, EarlyView.
Abstract This study provides an initial characterization of Stardust Mine, a fresh gabbroic enriched shergottite collected in Arizona, USA, in September 2024 and is the first Martian meteorite to be unequivocably collected on US soil. Analysis was conducted on the type specimen and finds that Stardust Mine is composed of equal proportions of pyroxene ...

Solar System material reaching neighboring star systems

Astronomy & Astrophysics
Context. In our Solar System, few macroscopic objects have been observed to be moving in hyperbolic orbits and, thus, they must have originated from interstellar space. Some meteoroids are also suspected to have an interstellar origin.

Potential of VIS‐IR imaging spectroscopy and SEM‐EDS and EMPA to map the mineralogical composition of NWA 7317 (CR6)

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 1026-1044, June 2026.
Abstract Asteroid compositional analysis relies on comparing reflectance spectra with laboratory data from well‐characterized meteorites. To advance this comparison, we performed a comprehensive laboratory analysis on a slab of the Northwest Africa (NWA) 7317—CR6 carbonaceous chondrite.

Geminids are initially cracked by atmospheric thermal stress

Astronomy & Astrophysics
Context. Geminids have the highest bulk density of all major meteor showers and their mechanical strength appears to depend on their mass. They are also the most active annual shower, enabling detailed studies of the dependence of their physical and ...
