TL;DR: Spectral observations and a principal components analysis suggest that Ryugu originates from the Eulalia or Polana asteroid family in the inner main belt, possibly via more than one generation of parent bodies.

TL;DR: In this article, in situ thermal infrared observations of a boulder on the C-type asteroid Ryugu were reported, indicating high boulder porosities as well as a low tensile strength in the few hundred kilopascal range.

TL;DR: In this article, the authors collected observational evidence that supports the scheme of mass transfer on the nucleus of comet 67P/Churyumov-Gerasimenko and showed that up to 20% of the particles directly return to the nucleus surface.

TL;DR: The global trend of lobate flows suggests that differences in their geomorphology could be explained by variations in ice content and temperature at the near surface, and the identification of these potentially ice-related features suggests that there may be more ice within localized regions of Ceres’ crust.

TL;DR: Images from the Mobile Asteroid Surface Scout lander show that rocks on asteroid Ryugu are similar to carbonaceous chondrite meteorites, and close-up images of a rock reveal a dark matrix with small, bright, spectrally different inclusions, implying that it did not experience extensive aqueous alteration.
