Methane from UV-irradiated carbonaceous chondrites under simulated Martian conditions [PDF]

open access: yes, 2012
A UV photolytic process was studied for the production of methane from carbonaceous chondrites under simulated Martian conditions. Methane evolution rates from carbonaceous chondrites were found to be positively correlated to temperature (−80 to 20°C ...

Drelów, the 13th and latest meteorite fall in Poland—A typical L6 chondrite with shock veins

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 466-486, March 2026.
Abstract On Tuesday, February 18, 2025, at 18:04:14 local time, residents of Poland observed a bright fireball registered by many Polish fireball stations belonging to the Skytinel Network established a few months before by Mateusz Żmija. Thus, the meteoroid's orbit, atmospheric trajectory, and the strewn field were calculated, and over 70 fragments ...

Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 522-547, March 2026.
Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.

Radiosonde‐to‐Space (R2S) Atmospheric Specifications: Bridging Observations and Models for Infrasound Propagation

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Infrasound propagation is inherently asymmetric and time‐dependent, making accurate atmospheric specifications essential for predicting when and where signals arrive. The Naval Research Laboratory's Ground‐to‐Space (G2S) model is widely used for this purpose, yet discrepancies between G2S predictions and observations highlight the need for ...

Is asteroid 2002NY40 a rubble pile gravitationally disrupted [PDF]

open access: yes, 2008
The existence of meteoroid streams containing meter-sized meteoroids capable of produc- ing meteorites after atmospheric interaction was pro- posed quite recently [1].

Observational Evidence for Wind‐Driven Low‐Pass Filtering of Infrasound at Short Range

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Infrasound from controlled explosions provides a unique opportunity to isolate atmospheric effects on propagation. We report observations from two campaigns in May and October 2024, each featuring 10‐ton TNT‐equivalent controlled surface chemical explosions recorded by a dense network of 31 single‐sensor stations within 23 km.

Disintegration and Skipping Dynamics of Bilobate‐Shaped Meteoroids for Generating Ultra‐Long Strewn Fields

open access: yesEarth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The longest known Aletai meteorite belt presents a unique phenomenon in meteoroid dynamics. To investigate its formation mechanism, this study introduces a bilobate‐shaped meteoroid model, emphasizing aerodynamic interactions and structure evolution.

Weather Radar Detection and Analysis of Bolides in the Day or Night

open access: yesAdvances in Astronomy
Weather radars have proven to be valuable tools for detection and analysis of meteorite falls, specifically identifying and analyzing falling meteorites which have survived the initial fireball.

Decameter‐Sized Earth Impactors—II: A Bayesian Inference Approach to Meteoroid Ablation Modeling

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Small asteroids and large meteoroids frequently impact the Earth, though their physical and material properties remain poorly understood. When observed as fireballs in Earth's atmosphere, these properties can be inferred from their ablation and fragmentation behavior.
