Simulation of meteoroid and asteroid explosion event by terawatt-class laser Project ID: GA21-11366S Provider: Czech Science Foundation Period: Jan 01, 2021 - Dec 31, 2023 Recipient -- coordinator: Jaroslav Heyrovsky Institute of Physical Chemistry -- RNDr. Martin Ferus, Ph.D. Co-recepient(s) / PI(s): Faculty of Nuclear Sciences and Physical Engineering, Czech Technical University, Prague -- Ing. Barbora Drtinová, Ph.D. Institute of Plasma Physics, Czech Academy of Sciences, Prague -- Ing. Michaela Kozlová, Ph.D. Co-investigators from IPP P. Gajdoš, T. Uhlířová, M. Červeňák, D. Mašlárová Aims of the project: The research in the field of meteor science instantly continues and there is still a wide range of unanswered questions and challenging scientific topics strongly connected to fundamental study of physical and chemical processes and consequences related to an atmospheric entry, the impact, meteor plasma, meteoroid bodies and meteorites. Using unique large terawatt laser facility PALS, we intend to experimentally explore chemical and physical consequences of large explosion and cataclysmic impact events. Specifically, the project is focused on investigation of plausibility of spectral detection of such an events on exoplanets using ARIEL exoplanet telescope mission and beyond, heterogeneous chemistry of material released during explosion or impact (synthesis of H2, HCN, PH3 and composition of dust) and laboratory observation of spectra and fragmentation of meteorite samples during laser target experiments.
