Abstract: Abstract Samples collected on carbonaceous asteroids and preserved from terrestrial alteration are key witnesses of the early evolution of the Solar System. Here we present the results of the characterization, by the near-IR hyperspectral microscope MicrOmega within the ISAS/JAXA curation center, of the samples returned from the Bennu asteroid by the OSIRIS-REx mission. We compare these samples to those from Ryugu, analyzed with the same instrument and at the same facility, using gram-scale quantities of material. We demonstrate that Bennu and Ryugu samples exhibit similar near-IR diagnostic spectral properties, from the centimetre down to the sub-millimetre scale. A wide variety of compounds are detected within a similar phyllosilicate-rich matrix, including diverse carbonates, H2O-rich and NH-rich phases, and notably Hydrated Ammonium-Magnesium-Phosphorus-rich grains. Rarely, anhydrous silicates are also observed. Despite some minor, although significant differences, our results indicate that the parent bodies of Ryugu and Bennu share similar formation and early evolution processes in the outer protoplanetary disk. Their main characteristics would, thus, define an entire class of objects which might have driven specific evolutionary pathways for terrestrial planets, including that which led to life on Earth.
