Review of Asteroid, Meteor and Meteorite Type Links
[#6098]
In 2018, there were only hints that different meteorite types arrive on different impact orbits, but now those hints have evolved into patterns that are distinctly different for H, L, and LL chondrites.

Determination of Parameters of Fireball Through Metaheuristic Optimization
[#6401]
We introduce a metaheuristic algorithm method to estimate meteoroid parameters without explicitly using velocity profiles. The method shows good agreement for large meteoroids but discrepancies for fragile ones.

Taghzout Meteorite: The First Recovered Fall in Morocco Detected by MOFID Cameras Network
[#6030]
Taghzout is a unique meteorite fall with a trajectory and an orbit collected by the Moroccan Observatory for Fireball Detections MOFID. It's an H5 meteorite among the 25th Moroccan eyewitnessed falls.

Al-Khadhaf: A Camera-Observed H5-6 Fall from Oman
[#6140]
This work describes the recovery and classification of Al-Khadhaf, a H5–6 chondrite that fell on 8 March 2022 in Oman. This meteorite is the first camera-observed fall from Oman.

PRISMA: A Fireball Network for the Recovery of Freshly-Fallen Meteorites in Italy
[#6335]
PRISMA is the Italian fireball network for the recovery of freshly-fallen meteorites on the Italian territory. To date, the observations and data analysis of the PRISMA project allowed for the recovery of two meteorites, namely Cavezzo and Matera.

Reconstructing Complete Meteor Velocity Profiles Using Radar Head Echo Detection
[#6312]
We present a method aimed at overcoming the inherent limitations of radar detection by developing modeling techniques capable of extrapolating pre-atmospheric velocity even before a meteoroid enters the radar's observational volume.

NIMROD UK Radar Data Use in Tracking and Locating UK Meteorites Falls
[#6391]
Following success locating meteorites in the USA and Australia using NOAA radar data, UK NIMROD weather radar data has been used to attempt to confine strewn fields of meteorites and to assess the likelihood of retrieval for recent and past falls.

Finding the Rocks: A Machine Learning Strategy for Drone-Assisted Meteorite Searching
[#6416]
Rapid recovery of freshly-fallen meteorites is key, but it can be subject to various factors that hamper success. We studied how to leverage the aerial vantage point of drones with machine learning to improve the odds for successful recoveries.

Omani-Swiss Meteorite Searches 2001–2024: Main Results and Open Questions
[#6136]
Searches for meteorites in Oman 2001–2013 yielded 7300 samples from ~1400 falls. An overview of the meteorite distribution, find frequencies, and the most important finds is given, and open questions are discussed.
