Abstract

The Near-Earth asteroid 162173 Ryugu is the target of the JAXA sample return Hayabusa2 mission, which arrived at the asteroid in June 2018 and will analyse the surface until December 2019. Reflectance spectra of the Ryugu surface, acquired by the NIRS3 spectrometer (Near-Infrared Spectrometer), revealed a dark object with a positive slope, ranging from 0.10 to 0.29. A detailed analysis about areas with different spectral slopes has been performed, with the aim to detect physical/chemical variations and better constrain the history of Ryugu.
