Clay minerals, or analogously phyllosilicates, are some of the most astonishing minerals
ever discovered on Mars due to their roles as indicators of water-rock interaction. Their …

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 …

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 …

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 from the carbonaceous asteroid (162173) Ryugu provide information on the
chemical evolution of organic molecules in the early solar system. Here we show the …

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

Samples from asteroid Ryugu returned by the Hayabusa2 mission contain evidence of
extensive alteration by aqueous fluids and appear related to the CI chondrites. To …

The carbonaceous asteroid Ryugu has been explored by the Hayabusa2 spacecraft to
elucidate the actual nature of hydrous asteroids. Laboratory analyses revealed that the …

Large amounts of nitrogen compounds, such as ammonium salts, may be stored in icy
bodies and comets, but the transport of these nitrogen-bearing solids into the near-Earth …
