Investigating the source regions of meteorites is one of the major aims of current research of small interplanetary bodies. Unfortunately, meteorite findings are not common and in addition provide information mostly for asteroidal materials. Spectroscopic observations of meteors may have the potential to classify the material of meteoroids entering the Earth's atmosphere. This presentation is devoted to the simulated atmospheric entry of meteoroids using meteorite samples. We used the plasma wind tunnel, which reproduce the atmospheric entry-like heating conditions, at the Institute of Space Systems at the University of Stuttgart with the aim of collecting six emission spectra in the visible wavelength range of different meteorite types CV, H, L and LL. Description of the project, laboratory experiment and examples of meteorite ablation video recording are going to be presented.
