Abstract
In this abstract we show the preliminary results of the micro-comparison between two basaltic shergottites DAG489 and NWA8657 by means of the Spectral Imager (SPIM)spare of Dawn spectrometer. The spatial resolution of SPIM enable the interpretation of spectra pixel by pixel to obtain a more reliable assignment of endmembers/minerals occurring in these meteorites. The preliminary investigations revealed a difference in pyroxenes composition and variability, and in the occurrence of hydrated phases in DAG489. Further studies are ongoing on these meteorites that will support the interpretation of MaMISS imaging spectrometer onboard of the next ExoMars2020 mission.
