Pebbles and sand on asteroid (162173) Ryugu: In situ observation and particles returned to Earth
Science, 2022The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. The mission performed two landing operations to collect samples of surface and subsurface material, the latter exposed by an artificial impact.

Bright carbonate veins on asteroid (101955) Bennu: Implications for aqueous alteration history
Science, 2020The complex history of Bennu's surface The near-Earth asteroid (101955) Bennu is a carbon-rich body with a rubble pile structure, formed from debris ejected by an impact on a larger parent asteroid.

Asteroid Fragmentation and Evolution of Asteroids
Annual Review of Earth and Planetary Sciences, 2000To understand the complex collisional history of asteroids and explain their observed characteristics, it is necessary to be able to describe the fundamental physics of large-scale impact events. Because data collected on collisional outcomes is derived from small-scale laboratory experiments, success at describing asteroid evolution hinges ...

Itokawa (25143) is a near-Earth stony (S-type) asteroid. This object has been the first asteroidal target for a sample return mission, the JAXA Hayabusa mission. Itokawa is likely a contact binary. It is small (major axes 530 m, 290 m, and 210 m) and has a rotation period of about 12.13 h.

(162173) Ryugu is a near-Earth C-type (i.e., carbonaceous) asteroid. It has been, after Itokawa, the second target for an asteroidal sample return, thanks to the JAXA Hayabusa2 mission (Watanabe et al. 2019). Most interestingly, Ryugu in situ observations in 2018–2019 have confirmed, as expected from its classification, the presence of significant ...

(101955) Bennu is a near-Earth carbonaceous asteroid, suggested to belong to the taxonomic class B or more likely to the rare class F (Belskaya et al. 2005) from its spectro-polarimetric properties (Cellino et al. 2018). It has been the target of the NASA OSIRIS-REx sample return mission, which rendezvoused with it in late 2018 and collected samples in
