Dear Colleagues, Apologize for multiple postings. *Links updated!* We are pleased to announce a five-hours seminar on the meteoritics science with particular emphasis on importance of meteorites related with planetary formation and impact hazards, sample return missions from other celestial bodies, and from Antarctica. The seminar will be VIRTUAL from Agricultural University of Athens on *Thursday **7th July 2022*. Do not hesitate to visit our website ( https://sites.google.com/view/meteor-athens2022). Meteorites are rare objects containing precious information on the origin of our solar system. They preserve evidence of processes that occurred on asteroids in the first few million years of our solar system’s history, but also of later stage events. These asteroids were heated by radioactive decay, leading to thermal metamorphism and release of fluids. They also experienced multiple collisions that left shock damage in the meteorites. Some of these meteorites are “finds”, often recovered in Antarctica or in hot deserts, but the most pristine ones are observed “falls” that are quickly recovered after their landing on Earth, preventing terrestrial alteration.
