The Hayabusa2 mission journeys to C-type near-Earth asteroid (162173) Ryugu (1999 JU
3) to observe and explore the 900 m-sized object, as well as return samples collected from …

BepiColombo has a larger and in many ways more capable suite of instruments relevant for
determination of the topographic, physical, chemical and mineralogical properties of …

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

Micrometeorite impacts and solar wind irradiation, the dominant space weathering (SW)
processes, largely modified compositions and microtexture of soil materials on the Moon …

The Hayabusa2 spacecraft delivered samples of the carbonaceous asteroid Ryugu to Earth.
Some of the sample particles show evidence of micrometeoroid impacts, which occurred on …

We present an experimental study on ion irradiation of carbonaceous chondrites, simulating
solar wind irradiation on primitive asteroids, to better constrain the space weathering …

Abundant nanophase iron (np-Fe0) is ubiquitously formed on the surface of the Moon and
other airless bodies through space weathering processes, and plays a dominant role in …

The isotopic composition of water in Earth's oceans is challenging to recreate using a
plausible mixture of known extraterrestrial sources such as asteroids—an additional …

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 …

Surface‐correlated nanophase iron particles (npFe0) alter the reflectance spectrum
characteristics of airless bodies, thus making it an essential aspect of studying space …
