Space weathering record and pristine state of Ryugu samples from MicrOmega spectral analysis
The samples returned from asteroid Ryugu were collected both at its surface and at its subsurface by Hayabusa2 and can, thus, provide information on the space weathering of C-type asteroids at different depths...

Article
Constraints on Solar System early evolution by MicrOmega analysis of Ryugu carbonates
The samples returned from a C-type asteroid (Ryugu) by the Hayabusa2 mission constitute unprecedented access to carbonaceous material never exposed to Earth’s atmosphere that may still contain phases formed in...

Article
First compositional analysis of Ryugu samples by the MicrOmega hyperspectral microscope
The characterization of objects that have best preserved the mineralogical and molecular phases formed in the earliest stages of the Solar System evolution is key to understanding the processes that led to the...
