C-type asteroids are considered to be primitive small Solar System bodies enriched in water
and organics, providing clues to the origin and evolution of the Solar System and the …

Simple Summary Organic matter is an integral part of all living things on our planet, but
abiotic (not relating to life) organic matter can be found throughout the Solar System within …

This paper summarizes the evidence for the optical effects of space weathering, as well as
the properties of the surface that control optical changes, on asteroid (101955) Bennu. First …

Returned samples from Cb-type asteroid (162173) Ryugu exhibit very dark spectra in visible
and near-infrared ranges, generally consistent with the Hayabusa2 observations. A critical …

Ryugu is a carbonaceous rubble-pile asteroid visited by the Hayabusa2 spacecraft. Small
rubble pile asteroids record the thermal evolution of their much larger parent bodies …

Planetesimals—the initial stage of the planetary formation process—are considered to be
initially very porous aggregates of dusts,, and subsequent thermal and compaction …

Abstract Hayabusa2 is the Japanese Asteroid Return Mission and targeted the
carbonaceous asteroid Ryugu, conducted by the Japan Aerospace Exploration Agency …

Various natural effects gradually alter the surfaces of asteroids exposed to the space
environment. These processes are collectively known as space weathering. The influence of …

Hayabusa2 spacecraft successfully collected rock samples from the surface of C-type near-
Earth asteroid 162173 Ryugu through two touchdowns and brought them back to Earth in …
