JAXA's Hayabusa2 mission carried out a collection, never accomplished before, of samples of a very primitive carbonaceous asteroid, and successfully brought them back to Earth in early December 2020. The samples are now stored in the “Curation Facility” of ISAS, in Sagamihara (Japan), in ultra-clean chambers, in a controlled atmosphere, where initial analyzes are being carried out. These include a pioneer characterization by infrared hyperspectral microscopy, using the MicrOmega instrument developed at IAS, and integrated into the Curation Facility.
