The Hayabusa2 spacecraft collected samples from the surface of the carbonaceous near-
Earth asteroid (162173) Ryugu and brought them to Earth. The samples were expected to …

Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2
spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide …

Carbonaceous meteorites are thought to be fragments of C-type (carbonaceous) asteroids.
Samples of the C-type asteroid (162173) Ryugu were retrieved by the Hayabusa2 …

Presented here are the observations and interpretations from a comprehensive analysis of
16 representative particles returned from the C-type asteroid Ryugu by the Hayabusa2 …

Without a protective atmosphere, space-exposed surfaces of airless Solar System bodies
gradually experience an alteration in composition, structure and optical properties through a …

Volatile and organic-rich C-type asteroids may have been one of the main sources of Earth's
water. Our best insight into their chemistry is currently provided by carbonaceous chondritic …

Samples of the carbonaceous asteroid (162173) Ryugu were collected and brought to Earth
by the Hayabusa2 spacecraft. We investigated the macromolecular organic matter in Ryugu …

The lack of pyrimidine diversity in meteorites remains a mystery since prebiotic chemical
models and laboratory experiments have predicted that these compounds can also be …

The pristine sample from the near-Earth carbonaceous asteroid (162173) Ryugu collected
by the Hayabusa2 spacecraft enabled us to analyze the pristine extraterrestrial material …

The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173)
Ryugu. The mission performed two landing operations to collect samples of surface and …
