Helping to bring an asteroid home

(A) DCAM3 image of the ejecta created during the SCI impact, with four separate rays of material. (B) ONC optical image of the impact site, with numbers corresponding to the ejecta rays in (A). (C). Change in reflectivity before and after the SCI impact. Darker regions are thought to indicate material ejected from below the surface. (Figure 4 in Arakawa et al., Science 2020.)

Are primitive asteroids “fluffy”?

Asteroid Ryugu from an altitude of 6km. Image was captured with the Optical Navigation Camera - Telescopic (ONC-T) on July 20, 2018. (JAXA, University of Tokyo, Kochi University, Rikkyo University, Nagoya University, Chiba Institute of Technology, Meiji University, University of Aizu, AIST.)
